Mould and Damp: The Hidden Physical and Mental Health Risks in South African Homes

maggie_adminsafe — Thu, 05 Mar 2026 06:23:54 +0000

Mould and Damp: The Hidden Physical and Mental Health Risks in South African Homes

In South Africa, damp and mould are common problems in both residential and commercial buildings, especially in coastal regions, high rainfall areas, and poorly ventilated structures. While most people recognize the damage damp causes to walls and ceilings, fewer understand the serious impact it can have on physical and mental health.

Damp environments create the ideal conditions for mould growth. Even when mould is not immediately visible, microscopic spores can enter the air and be inhaled, affecting the lungs, immune system, and overall well-being. According to the National Institute for Communicable Diseases and the South African Medical Research Council, prolonged exposure to mould and damp indoor environments can significantly increase the risk of respiratory illness and worsen existing health conditions.

Respiratory Health Risks

Mould spores primarily affect the respiratory system. Inhaling these spores can lead to both short-term irritation and long-term illness.

Common symptoms include:

Persistent coughing
Wheezing and shortness of breath
Sinus congestion and throat irritation
Asthma flare-ups or worsening asthma symptoms
Increased risk of lung infections

In South Africa, where asthma rates are already high, particularly among children in urban and informal housing environments, damp conditions can make respiratory illnesses more severe and more frequent.

Black mould, often found on damp walls and ceilings, can release harmful spores that may lead to serious infections, particularly in individuals with weakened immune systems.

Physical Health Effects Beyond the Lungs

Exposure to damp and mould can also affect other parts of the body, including:

Eye irritation and redness
Skin irritation, rashes, and eczema
Allergic reactions
Fungal skin infections

These conditions can reduce quality of life and lead to ongoing discomfort. People living in overcrowded housing or poorly maintained buildings face increased risk due to prolonged exposure.

The Mental Health Impact of Living with Damp and Mould

The effects of damp and mould extend beyond physical health. Living in a damp, mould-affected environment can take a serious toll on mental well-being. Common emotional and psychological effects include:

Stress and anxiety about health risks
Embarrassment or reluctance to invite guests into the home
Frustration with ongoing maintenance problems
Feelings of helplessness or depression

In many South African households, where homes represent safety, stability, and pride, visible mould and structural deterioration can deeply affect emotional well-being. This often creates a harmful cycle: as damp worsens, health declines, stress increases, and overall quality of life is reduced.

Most Vulnerable Groups

Certain individuals are especially at risk from damp and mould exposure:

Children, whose lungs are still developing
Elderly individuals
People with asthma or chronic lung conditions
Individuals with weakened immune systems
Pregnant women
People living in overcrowded or poorly ventilated housing

In South Africa, vulnerable communities, particularly those living in informal settlements or older buildings, face higher exposure due to structural and environmental conditions.

Damp and Mould: A Public Health Issue

Damp and mould are not just maintenance issues. They are public health concerns. Addressing moisture problems early can help prevent serious health complications, reduce medical costs, and improve quality of life.

Property owners, contractors, and maintenance professionals all play a critical role in preventing and treating damp before it leads to mould growth.

Preventative waterproofing, proper ventilation, and early intervention are essential to creating safer, healthier living and working environments.

Final Thought

Damp does not only damage buildings. It affects people.

By identifying and addressing damp early, we protect not only structures but also the health, dignity, and well-being of those who live and work within them.

Uv Protection For Waterproofing

maggie_adminsafe — Tue, 20 Jan 2026 11:06:09 +0000

UV PROTECTION FOR WATERPROOFING

Most of us are aware of the dangers of Ultra Violet rays on our skin. We protect ourselves as much as possible with clothing and protective sun blocking creams or simply avoid excessive exposure to the sun’s rays as much as possible.

But what of our buildings and especially our waterproofing products?

A French team of scientists conducted a 10-year climatology study using ultraviolet radiation measuring instruments based at Cape Town international airport. The results showed very high UV radiation exposure, especially during the austral summer, often reaching the “extreme” category (more than 11) on the World Health Organisation UV index.
South Africa experiences particularly high levels of surface and tropospheric ozone, especially in July and August, largely due to biomass burning activities.
UV attacks on buildings involve ultraviolet radiation from the sun degrading building materials over time, causing color fading, discoloration, reduced tensile strength, cracking, and delamination. This photo-degradation is caused by the breaking down of chemical bonds within materials like paint, plastics, wood, plaster, brickwork and concrete. Damage levels vary by location, building orientation (north and west-facing sides are more exposed), and the specific material’s UV resistance.

The direct effects of this process include the loss of impact strength, changes in color, cracking, loss of elongation, tensile strength, or chalking of the surface.
UV has a very serious impact on our waterproofing materials. Acrylics and most paints usually require refreshing of the coatings every 2-3 years. The surface starts to delaminate and “blister’ allowing UV to further attack the underlying substrate which invariably ends up in cracking or in degradation of the material. Cementitious waterproofing products are similarly
affected by UV and need some form of protection to prevent cracking. Polyurethane waterproofing products may “chalk” or yellow if not covered by an aliphatic UV stable and UV resistant top coat.

Bitumen products also need protection from UV rays and this is usually provided by Bitumen Aluminium paint. This not only reflects the sun’s rays providing cover to the underlying Bitumen but also lowers the heat absorbed by the building structure. Some individuals attempt to coat the Bitumen with acrylic paint but this soon de-bonds from the surface due to both UV attack and the “leeching” of chemicals from the bitumen membrane. This “leeching” is often under-estimated by contractors. Manufacturers of Bitumen Aluminium paint stress the fact that Bitumen Aluminium paint should not be applied to Bitumen membranes within 7 days of application. This is to allow chemicals in the bitumen to settle. If ignored this will often lead to “bronzing” of the paint and even “crocodiling” of the paint surface.

UV is most damaging to horizontal surfaces. Vertical surfaces have the ability to deflect UV rays whilst horizontal surfaces absorb them leading to eventual damage to the surface.

Do your waterproofing a favour. Provide it with a suitable sun block!

Protecting Your Walls: The Importance Of Masonry Sealants

maggie_adminsafe — Tue, 06 Jan 2026 00:39:44 +0000

PROTECTING YOUR WALLS: THE IMPORTANCE OF MASONRY SEALANTS

Moisture is one of the biggest threats to the structural integrity of buildings. Rain, condensation or groundwater can penetrate walls and lead to cracks, frost damage and the growth of algae, fungus or moss. Over time, salt and lime deposits may appear, leaving unsightly marks, while dirt carried by rainwater can stain masonry surfaces.

The best way to prevent these problems is to protect your walls with a high-quality masonry sealant, which creates a long-lasting barrier against water without affecting the wall’s natural appearance.

How Masonry Sealants Safeguard Your Building

Masonry sealants work by stopping water from entering the walls while allowing trapped moisture to escape. This “breathable” protection helps prevent internal issues such as peeling paint, mould and damaged plaster. Benefits of using a masonry sealant include:

Reducing the risk of structural damage from moisture
Preventing algae, moss and other biological growth
Minimising surface staining and efflorescence
Extending the lifespan and appearance of your walls

Stormdry Masonry Protection Cream: Effective, Long-Term Protection

At Safeguard Chemicals, we offer Stormdry Masonry Protection Cream, a trusted solution for keeping walls dry and protected for decades.

Solving Pinhole And Adhesion Problems With Liquid Waterproofing Products

maggie_adminsafe — Mon, 22 Dec 2025 09:20:50 +0000

SOLVING PINHOLE AND ADHESION PROBLEMS WITH LIQUID WATERPROOFING PRODUCTS

The presence of pinholes in liquid-applied waterproofing products is a problem faced by all of us at some time. When this occurs on exposed external surfaces it can result in water ingress and damage.

There are several reasons why pinholes and lack of adhesion can occur:

Inadequate cleaning of the substrate

Failure to thoroughly clean the surface, especially after grinding, removing all loose material and grease is a major source of failures. It is often not good enough to to simply brush the surface. Dust can stick in small pores and crevices affecting adhesion

Concrete off-gassing

When concrete surfaces are ground it exposes the pores of the substrate. These pores can trap moisture and gases within the concrete especially when newly laid. Changes in temperature, pressure or even sunlight can cause gases to escape from the substrate in a process called off-gassing. When waterproofing is applied over a surface that is still off-gassing, tiny bubbles form in the liquid membrane as the gases escape, leading to pinholes in the membrane. These pinholes compromise the waterproofing, allowing moisture ingress. This is why it is so crucial for your primer coat to fill every single pore so as to block the passage of these gases and to ensure that your membrane has no weak spots.

Incorrect or Insufficient Primer

The purpose of the primer is to seal the pores of the substrate and to ensure maximum adhesion of the waterproofing membrane and no pinholes.

Moisture in the substrate

If the concrete/substrate is still curing or contains moisture, the moisture will rise to the surface and push its way through the waterproofing membrane causing pinholes and delamination. It is thus essential to ensure that the surface is fully dry before applying the waterproofing. The use of a moisture meter to determine the levels of moisture in the substrate is strongly advised.

Application in humid or unfavourable conditions

High humidity or rapid temperature changes during application of many liquid-applied membranes, especially polyurethanes, can cause premature curing, trapping air or moisture in the membrane. This appears as bubbles in the product, ultimately leading to
pinholes. Regular checking of weather forecasts is a major factor in project management. Some products will specifically advise against application if rain is expected within a few hours.

Excessive film thickness

Applying product too thickly can result in the surface drying faster than the layer beneath. This creates trapped air pockets that eventually lead to pinholes as the product cures unevenly. Application of multiple thinner coats will prevent these problems.

Conclusions

Like the application of any product, surface preparation is key to a successful outcome. Taketime to inspect your substrate prior to application and take all necessary steps and precautions to avoid possible failure. Doing it right first time will prevent the need for costly remedial work and damage to your professional image.

Drying Time V Curing Time

maggie_adminsafe — Tue, 09 Dec 2025 09:40:06 +0000

DRYING TIME V CURING TIME

When working with liquid-applied waterproofing products it is important to understand the difference between drying time and curing time and is vital in ensuring the best performance and longevity of the product or system. Failing to understand the difference between the two can lead to failure of the product – either immediately or in the short to medium term – due to a lack of adhesion or compromise of the waterproofing.

So let’s start by looking at Drying Time

What is Drying Time?

Drying time refers to how long it takes for the liquid system to become touch-dry or reach a point where it is no longer wet to touch. This point is usually when solvent or water evaporation takes place from the product.

Factors affecting drying time:

Ambient temperature and humidity – warmer temperature and low humidity accelerate drying, whilst cold temperatures and high humidity slow it down.
Ventilation – good ventilation or airflow speeds up drying time by allowing moisture or solvents to evaporate more quickly
Coating thickness – thicker layers take longer to dry. Multiple thin layers are quicker to dry and give fewer problems – pinholes etc
Type of product – some products such as solvent-based products dry faster than water-based or cementitious products.

What is Curing Time?

Curing time is the period required for a waterproofing membrane to fully react and develop its optimal strength, adhesion and waterproofing properties. Unlike drying time, which primarily involves moisture or solvent evaporation, curing time involves chemical reactions that solidify the membrane’s structure.

Factors affecting curing time:

Chemical composition – Polyurethane and epoxy-based membranes require longer curing times compared to acrylic or cementitious systems.
Ambient temperature and humidity – Just like drying time, curing is affected by environmental conditions, with lower temperatures extending the process.
Water exposure – Premature exposure to water before curing can compromise membrane performance – particularly acrylics
Number of coatings – additional coats extend curing time as each layer needs to bond properly with the previous one. This is particularly so of polyurethanes.

Understanding the difference between drying and curing

Application time

Drying time determines when you can apply the next coat of waterproofing

Curing time determines when the surface is sufficiently ready for tiling, screeding or exposure to water or traffic.

Failure prevention

Rushing the installation process based on drying time alone can lead to weak adhesion and compromised waterproofing.

Ensuring proper curing before exposure to moisture prevents delamination or softening, even re-emulsification in the presence of water

Product Specifics –

Always check manufacturer details for both drying and curing times

Some products have very lengthy curing times compared to drying especially where traffic may be involved

Conclusions

Always check manufacturer specifications and application details and check expected weather conditions both during and after application.

By understanding the differences between drying and curing times you will avoid costly mistakes and waterproofing failures and ensure that the product performs to expectations. Proper planning and preparation will make the difference between success and failure.

BASEMENTS AND CELLARS

Basements and cellars should ideally be waterproofed on the positive side of the walls during the construction phase. However, either this does not happen or at some stage the waterproofing fails.

Under these circumstances it is necessary to waterproof the insides of the walls (negative side) in a process called “tanking”.

Surprisingly, national building regulations have no specific reference to the waterproofing of basements, cellars and other sub-terranean structures. There is, however, in SANS 10021:2006 a reference to “dry” and “wet” sites inferring that there needs to be additional measures undertaken in “wet” sites or wherever water tables are likely to be affected by seasonal rains.

For “dry” sites it is usual to apply one layer of 4mm APP torch-on membrane to the walls or a suitable liquid-based polyurethane waterproofing. The success of torch-on membrane is based on full adhesion of the membrane to the underlying substrate and the careful sealing of all overlaps. Due to the weight of the rolls, it is common for lengths of membrane to be cut from the roll, increasing the number of overlaps that have to be sealed.

Liquid polyurethanes on the other hand can be applied in 2 coats using a roller or brush. The system is seamless with no overlaps to create potential points of moisture ingress. The product also has huge flexibility which is a huge advantage during the settlement of the building when waterproofing products can be subjected to major stresses.

Polyurethane waterproofing products are more than capable of handling the additional pressure of “wet” sites, but when using torch-on membrane it is advisable to use 2 layers, with the second layer positioned in such a way as to protect the underlying laps.

Once this initial waterproofing fails, it is almost taken for granted that there can be no remedial action on the positive side. In many cases there are adjacent roads or walkways or simply backfill that has been applied all around the building. The only way of treating moisture ingress is, therefore, from the negative side of the walls.

There are few waterproofing products that can handle negative water pressure. Torch-on membrane, cold bitumen and polyurethanes are all prone to separation from the substrate under such conditions. The most common alternative is the use of a cementitious product in a process called “tanking”.

Depending upon the depth underground and the degree of water pressure, this can normally be achieved using a cementitious slurry such as our SWS Slurry. 2-3 coats of slurry will need to be applied to the walls once plaster has been removed. NEVER apply slurry over plaster especially if this plaster is already contaminated with salts. This is inviting failure. Always pay particular attention to the wall/floor joint which is the weakest point in the structure, and preferably re-inforce this using Fillet Seal. Cut a “V” joint into the wall at the base and pack this area with the Fillet Seal mixed with water or diluted Bondaid Plus. You may also need to apply several coats of slurry to the floor if this too is leaking. It is absolutely vital that each layer of product fully cures before application of an additional coat.

There will be occasions, however, when normal waterproofing products are either inappropriate or inadequate to deal with the presence of subterranean moisture.

In these circumstances it is necessary to seek an alternate solution which accept the presence of moisture and merely channels it to a means of extraction.

One such product is Cavity Drainage Membrane (CDM).

The underground vaults in the Roman Baths in Bath, England were the subject of a major project run by Safeguard Europe. These vaults were some considerable distance underground and were constantly under water as a result of the high water table and lack of waterproofing.

Since there was considerable water pressure on the existing walls, it was decided to address the problem by installing a Cavity Drainage Membrane system. The CDM allowed water to be channelled to a self-actuating pump which then evacuated the moisture as long as it was present. By fitting the CDM system, it was possible to provide new walls and floor which gave a totally dry appearance, even though beneath the surface water penetrating the original walls and floor was being effectively drained.

CDM comes in 2m x 20m rolls and is attached to the wall using plastic plugs.

Rolls of CDM are joined together with a special waterproof double-sided tape. Plugs attaching the CDM to the wall are waterproofed using a further waterproof sealing rope around the head of the plug.

When joining two sections of CDM, apply the lower section over the upper section to ensure a watertight seal.

The finishing touch is the fitting of a pump in a sump dug into the floor and to which all moisture drains. From this self-actuating pump water is evacuated to the outside by means of piping. Remember that such pumps always require battery back-up or some other power source, particularly in South Africa!
