Roof Waterproofing

The A to Z of Roof Waterproofing

Firstly, an essential thing in every homestead, especially when rainy seasons or winter is approaching, is a quality waterproofed roof. You don’t want to place buckets strategically in your house every time it rains. Or worse, having to fork our tens of thousands to repair damaged structures. Therefore, it’s vital to know everything about roof waterproofing.

A waterproofed roof protects the house from rain damages, and your belongings will be safe despite heavy, ongoing rains. Roof leaks are preventable through proper maintenance and roof installation.

Roof Waterproofing Guideline

You may be wondering what roof waterproofing entails. It is the layer that’s added to the roof to guarantee that no water leaks occur. As much as many roof leaks causative agents exist, poor roof waterproofing is among the significant causes.

There are cities where heavy rains are typical, and storms occur often. That’s why it’s essential to have proper roof waterproofing.

Roof Repairs

This is what happens to a house with poor roof waterproofing;

  • The roof structure goes through damages, and this can get dangerous if it goes unattended for a long time. The dampness in your rooms will become extreme, causing mould growth within no time. Such damages end up causing a break down in the house due to insufficient support.
  • There will also be stains on your ceiling and walls when you have poor roof waterproofing. Removing the stains can be challenging. Mould growth also leads to health issues. Especially with those who already have complicated respiratory problems.
  • Interior damage to your furniture and other precious personal belongings. Should your office roof be leaking, this could cause significant damage to computers, servers, office furniture and more.

Materials Used To Waterproof Roofs

Now the best part of roof waterproofing is that it doesn’t require complex waterproofing systems. Unless in severe cases.

A lot of people presume that the tiles, shingles or membrane on their roof mean that their roof is watertight. Although, they help and prevent water from leaking into your home, it takes more than that to have a waterproofed roof.

The essential materials for waterproofing your roof are;

  1. Acrylic Waterproofing

This is a cost effective and durable compound, which is used in conjunction with SBP membrane. It is designed to waterproof ridge capping, parapets, roof screws and lap joints on metal roof sheeting.

  1. Barge Boards

Barge boards are fastened to the projecting gables of a tiled roof o give them strength and protection. They also conceal the exposed end of the roof. Therefore, preventing water from leaking in under the roof.

  1. Flashing

Roof flashings are a metal sheet that is installed in vents, chimneys, skylights or other vertical wall joints. The purpose of roof flashings is to divert water. Therefore, preventing the accumulation of water. The metal used in roof flashing include; aluminium, stainless steel, copper, and galvanized metals.

  1. Gutters

Gutters help in roof waterproofing, and they divert roof water to a place far from home. However, they need maintenance practices to prevent sagging or clogging. When installing a gutter, you need a professional plumber because incomplete or incorrect installation causes roof rotting.

  1. Roof Foil Underlay (Tiled Roof Waterproofing)

Underlayment is commonly used in roof installation as a water-resistant material for protection during harsh climatic conditions. There are many forms of underlayment materials, and they differ for flat or sloppy roofs.

  1. Torch On Membrane

torch on waterproofing membrane is made up of a combination of modified bitumen layers coated with various sticky, viscous organic liquids. Bitumen, a hydrocarbon made from crude oil, is one of the primary components of this membrane.

The multiple layers create a waterproof surface that is also resistant to the sun’s ultra-violet rays. The membrane is sealed onto the surface by heat fusion. Torch on membrane is usually used on flat roofs, balconies and retaining walls.Waterproofing Options

  1. Shutter Boards (For Boarded Roof Waterproofing)

The boards are essential when you are installing a boarded roof system. These sheets act as a roof foundation, and they follow the rafters to seal them appropriately, so in rainy weather conditions, you will be safe.


What To Do Before Waterproofing Your Roof:

It’s not easy deciding on the best solutions. Nowadays, you have to be careful when hiring a roofing contractor or waterproofing contractor for the installation of the best roof waterproofing.

Consider the reliability, expertise, and material choices because when you are choosing the best roof waterproofing, you should consider these factors;

  • Compatibility of the roof surface matters a lot when it comes to roof waterproofing solutions. You have to know what material is going to be used by the waterproofing contractor.
  • Clean the substrate thoroughly before applying the new roof waterproofing solutions. This increases the performance of the new waterproofing system.
  • You need to prime the surface to improve the adhesion of the membrane.

Lastly, the big question. How much does roof waterproofing cost? It’s okay to tense about how much the process will cost you. However, there are certain things you need to know as a homeowner.

The cost of waterproofing a roof depends on your roof system. The material and skillset involved are worth it and the roof benefits in more ways than one.

Keep in mind that quality matters a lot, so don’t go for low priced services and expect to get productive results from it. Maintenance and repair costs are incurred later on. However, this is normal as every structure requires maintenance at some point.

We hope this article gave you some more insight on what to expect. Please contact us should you require any advice or assessments.

Defects Of Plaster

Common Plaster Defects

Plaster defects have been a problem in South Africa’s building industry for decades. However, the SABS specifications and the National Building Regulations do not have any requirements covering plaster quality. Additionally, most contract documents are not clear on the subject. Therefore, it may be difficult to force the contractor to make repairs should there be any defects.

Defects most frequently noticed and plaster fall into one of the following categories:

  • Non-structural cracks
  • structural cracks
  • Debonding
  • lack of hardness
  • Grinning
  • Expansion
  • Popping

Non-Structural Cracks

“Crazing” is a network of fine cracks, usually in a hexagonal pattern, which measure between 5 and 75 mm across each hexagon. They are usually very fine and shallow and do not extend through the whole depth of the plaster.

They are usually the result of over-trowelling a rich mix (one with a high cement content) or using a sand containing an excessive amount of dust (more than 15% by mass passing a 0,075 mm sieve). plaster cracks

Crazing often occurs within a few hours of the plaster being applied to the wall and cracks may hardly be visible until dust or moisture makes them noticeable.

Craze cracks are of little importance, do not open and close with time, and can be covered using a reasonable quality paint. Glass fibre tissue is applied during the painting operation.

Cracking which results when an excessive amount of water is lost from the plaster in the first hours after application is known as plastic shrinkage cracking.

Plaster will always shrink and crack so it is desirable that is should develop a large number of fine, unnoticeable cracks at close spacings. Plasters with very high cement contents and those which are made with poor quality sands having a high water requirement will tend to develop a few, widely-spaced cracks. Plaster applied in layers that are too thick will also tend to crack in this way. These cracks are normally stable and can be filled with a proprietary filler and painted over.


Structural Cracks

Some cracks visible in the plaster may result from cracking of the wall. This can be caused by differential movement of the foundations, moisture expansion or drying shrinkage of masonry units, or thermal movement of the roof.

This type of crack often forms in straight vertical or horizontal lines, or in stepped diagonal lines, and may be quite unsightly.structural cracks

The crack width will often vary with the seasons. Because these cracks originate in the wall and not in the plaster, repairing the plaster is ineffective.

A specialist should be called in to establish the cause of the cracking and to recommend remedial measures. Such measures may include structural alterations which change cracks into movement joints. Visible joints can be hidden by cover strips fixed on one side of the joint or sealed with elastomeric sealants.


Debonding Plaster

Debonding of plaster is often noticed as a hollow sound when the surface is tapped.

Plaster is inclined to curl and debond from the wall because the outside skin of the plaster that is exposed to the air will shrink at a different rate from the plaster in contact with the wall.

This is especially true of excessively thick plaster layers. Because debonding is generally the result of inadequate preparation of the substrate, it is important to make sure that the bond between plaster and wall is as good as possible. This can be done by:Debonding

  • Cleaning dusty or oily walls thoroughly.
  • Allowing the walls to reach the correct moisture content.
  • Using a cement slurry or spatterdash coat before plastering.
  • Using bonding liquids and following the procedure recommended by the manufacturer.

Small areas of debonding (about the size of a plate) are not significant, but larger areas should be removed and replaced.


Lack Of Hardness

There are no specifications covering the hardness or strength of plaster, and there is no reliable way of measuring it.

Scratch the surface with a hard sharp object such as a screwdriver or a key.

It is often better to have a slightly weaker plaster that is less likely to show significant cracking or debonding than one which is too strong. However, very weak plasters will be unable to resist impacts, will have reduced resistance to water penetration and picture nails will tend to fall out.

There are five common causes of soft plaster:

  • Insufficient cement
  • The use of sand containing excessive quantities of dust (more than 15% by mass passing the 0,075 mm sieve)
  • The use of a mix with poor water retention properties
  • The addition of extra water some time after first mixing (a practice known as retempering)
  • Rapid drying due to plastering in full sun or wind.

Painted plaster can only be removed and replaced. The inconvenience of this option has to be weighed up against living with the weak, unsatisfactory plaster.

A coat of high quality exterior paint will normally reduce the risk of water penetration to acceptable levels if the plaster is strong enough to hold such a paint. Areas which are particularly susceptible to impact, such as corners, can be re-plastered with relatively little disruption.


Grinning is the term given to the appearance of a plastered wall when the positions of the mortar joints are clearly visible through the plaster.Grinning

The difference in suction between the masonry units and the mortar causes grinning. Raking out mortar joints also causes grinning. Therefore, limit raking to soft clay brickwork. While grinning may be unsightly, it is unlikely to lead to further cracking. The choice is to live with it, or to remove and replace the plaster. Application of an undercoat or a spatterdash coat before plastering will help to avoid grinning.



This includes swelling, softening, layer cracking and spalling of the plaster. Proprietary gypsum-based products in the mix causes expansion.

Under moist conditions, the sulphate from the gypsum reacts with the portland cement paste and forms compounds of increased volume which disrupt the plaster.

The only remedy for this type of plaster defects due to gypsum in the mix is to remove and replace the plaster.


Popouts are conical fragments that break out of the surface of the plaster leaving holes which vary in size. The presence of contaminant particles in the plaster mix causes popping. It reacts with the moisture in the mix, expands and causes cavities in the plaster.plaster popping

Contaminants are usually seeds, other organic material, or particles of dead burnt lime.

The hole can be filled with a proprietary filler and painted over once the cause of the popout has been removed.

Will insurance cover rising damp?

Is Rising Damp Covered By Insurance?

Is rising damp covered by insurance policies? The short answer, no. Damp or condensation damage is not ordinarily covered by home insurance. When you apply for home insurance, you need to agree to a list of assumptions. One of the assumptions you need to make is that you agree your home is in a ‘good condition’. Therefore, if your home has rising damp, it is recognised as ‘not in good condition’, leading you to invalidating your insurance.

Some insurers offer specific cover for rising damp treatment. Others also offer a more comprehensive cover which includes rising damp.

Why Won’t My Insurance Cover Rising Damp?

When you submit a claim to your insurance, the claim implies that the damage was sudden or unforeseen. How

rising damp

ever, rising damp occurs over a period of time. Thus, the defect was caused by design or defective workmanship.

Damp is usually associated with poor waterproofing or defective damp proofing course. Therefore, if you submit a claim stating that the cause of loss is “damp”, you can expect your insurer to reject the claim. Purely because the loss occurred has been over time or that the loss was a result of wear and tear or defective waterproofing rather than storm, flood or bursting as is expected.

Rising damp treatment is not a cheap treatment and is intrusive to home owners or building occupants. It creates a large amount of dust and rubble as it includes hacking, drilling and chopping. The scope of work for rising damp treatment is always included in our quotations to the client. Therefore, you are aware of the mess it can make in the beginning. However, our damp team always clean up afterwards of course.

The Importance Of Proper Roof Maintenance

The Importance Of Roof Maintenance

Roof maintenance should be every building owner’s priority. Waterproofing materials can not last indefinitely. Additionally, if the current waterproofing is not care for and maintenance, its life expectancy will be drastically reduced. 

South African climate is harsh. We experience tremendous changes in temperature. We sometimes experience high quantities of sunlight and ultraviolet rays, a long with strong winds and heavy rain or hail storms. Thus, regular attention to all exposed roof waterproofing systems is a must. Although, often overlooked. 

This responsibility should lie not only with the building owner but also with the original waterproofing contractor committed to advising the building owner when his roof maintenance is due. This regular maintenance extends the life of the system whether under guarantee or not.roof maintenance

Although some waterproofing manufacturers of bituminous membranes state it is not necessary to apply any protective coating to their membranes,  the norm is to initially apply at least one if not two coats of bituminous aluminium paint. The location of the roof will depend on how often a maintenance repaint is required.

In an industrial area where there is a lot of pollution, it might be necessary to repaint every one to two years.

Whereas in more rural areas, every four to five years might suffice. However, the industry ‘norm’ is every three years.

Basement Waterproofing

Basement Waterproofing in South Africa

We receive a lot of enquiries regarding basement waterproofing or sub-ground waterproofing. Very few waterproofing companies specialize in basement waterproofing because it is finicky work and requires advanced experience.

However, we love basement waterproofing purely because we have mastered the skills and techniques required for sub-ground waterproofing.

We offer written guarantees for all our basement projects. Additionally, we advice you which system is best suited for your current water ingress situation.

Basement Waterproofing Projects


What Causes Your Basement To Leak?

  • Incorrect design from building stage.
  • Excessively high water table and hydrostatic pressure.
  • Damaged waterproofing on external walls.
  • Root growth or structural movement.
  • Inadequate subsoil drainage.
  • Blocked or failed subsoil drainage.


Symptoms Of Your Basement Leaking

  • The most obvious symptom is water seepage through the wall floor joints. This is the open joint where your masonry meets the concrete.
  • Damp and muggy feeling inside the room.
  • Mould smell or growth.
  • Bubbling paint.
  • Efflorescence or salts visible on walls.
  • Lifting floor tiles (if any).


Basement Waterproofing Recommendations

If your basement leaks once or twice a year during a multi-day long down pour, you can tank the basement and waterproof it from the inside relatively easily.

However, if it leaks through normal Gauteng flash storms, we advise installing external subsoil drainage or an internal sump pump as an artillery measure to deal with the water.


My Basement Is Leaking. What Now?

The cheapest option and first point of call is to look at drainage in the vicinity. This alone may alleviate the problem entirely, depending on the severity of the leak.

However, if you have a sump pump or subsoil drainage, your best option is known as tanking. This is an application of waterproof, structural slurry capable of withstanding high levels of negative water pressure. Therefore, this is a highly effective system when installed correctly.


What Not To Do When Your Basement Leaks

  • Do not apply a paint on ‘damp proofing’ or ‘waterproofing’ paint to the internal walls.
  • Drilling holes in the wall to drain water out the room will only make it worse.
  • Don’t apply any system onto the painted walls or floors.
  • Selling your house is not necessary as this is completely salvageable.


We have successfully solved many basement waterproofing problems. If you have any other questions or concerns you would like to ask us, don’t hesitate to get in touch with our basement waterproofing specialists.

Example Of Rising Damp

Rising Damp Explained

What is Rising Damp?

Rising damp can be defined as moisture which rises up from the ground and travels upwards in the masonry of the building structure by means of capillary action. This moisture dries out on the wall surfaces and can present in various unsightly forms such as paint failure, discolouration and mould growth.

Capillaries are very narrow passages or tubes which occur in masonry. Capillary action is when moisture rises up in these tiny passages even against the force gravity.

The foundations of a standard dwelling are generally constructed of concrete laid onto compacted soil. Brick work, usually between 5 and 8 courses high is built on top of the concrete foundation. Do you want to know how much rising damp treatment costs? Read our article here, ‘How Much Does Damp Proofing Cost?’

A DPC (Damp Proof Course) usually consisting of a heavy-duty plastic layer is loose laid onto this. The rest of the wall is built on top of this plastic DPC layer. The section of brickwork between the foundation and DPC is designed to be a “wet zone.” The DPC is designed to prevent water from rising up beyond this wet zone. However, when various factors develop and the DPC is comprised, then rising damp can take place.

Rising Damp Explained


What Are The Signs Of Rising Damp?

Rising damp can occur to interior and exterior walls and usually presents in the lower portion of the wall typically up to a height of 1m. It is rare for rising damp to be higher than 1,2m.

However factors such as tile cladding or a waterproof plaster applied to lower section of walls without installation of a chemical DPC can cause this occurrence.

The use of a moisture meter is sometimes used by professionals to detect rising damp, but usually the signs are very obvious and is not a necessary tool.

There is moisture in walls naturally so using a moisture meter is almost always guaranteed to pick up moisture.


Signs and symptoms include the following:

  • Paint failure characterised by blistering and bubbling of the paint film.
  • Brown or darker stains or “tide” marks to the wall surfaces which is blemishes due to moisture in the wall.
  • Wall surfaces feel cold and clammy.
  • White powdery deposits on the wall surfaces, technically termed salts or efflorescence.
  • Crumbling and failure of plaster.
  • Rotting or warped skirting boards.
  • Mould smell which could be occurring under skirtings or carpets and is often is triggered by damp in walls.
  • Peeling or discoloration of wallpaper.
  • Rooms feel unusually cold in the winter months.
  • Mould on wall surfaces which is usually black in colour, but can also be brown, red, green and yellow.


What Causes It?

There are many possible causes of rising damp and these include the following:

  • DPC non existent, degraded or failed or is incorrectly positioned.
  • Moisture bypasses DPC via plaster from wet zone area.
  • Wall below DPC has been plastered and painted, which traps moisture inside the wall.
  • Excessive exposure of walls to rain due to design of house with no eaves or roofs with no gutters.
  • Ground level higher on other side of wall which breaches DPC.
  • Wooden floors which been removed and replaced with concrete

signs of rising damp


What Are The Detrimental Effects Of Rising Damp?

There are numerous adverse effects of rising damp. These would typically include the following:

  • Unsightliness. Paint failure occurs very quickly when rising damp is present and negatively impacts on the aesthetics of the building structure.
  • Devaluation of property. Buyers seldom want to purchase buildings which are damp affected.
  • Moisture in walls reduces insulation properties and makes buildings much colder in the winter months.
  • Damp in walls can trigger mould growth which has bad odour and is detrimental to health.
  • Rising damp can cause damage to property, especially to interior walls, including rotting of skirtings and carpets and rusting of metal door frames and electrical plug sockets.
