The guide to Waterproofing Membrane

Waterproofing membrane is a coat of water tight element that prevents leakage of water which usually be set on a surface. Waterproofing can be divided to two type which is liquid applied or in a form of sheet membrane. Water penetration can be thwart by applying these materials over the foundations (such as structural slab). Waterproofing membrane can be used to protect various areas such as the basement, roof and wall, but the main point is waterproofing main used to stop water from penetrating the foundation and protecting your construction from water damage.

Since Malaysia weather can be extreme in terms of heat, choosing a good quality waterproof membrane with high durability is crucial as a good waterproofing membrane is able to withstand the high temperature, chemicals and elongation that can withstand building movement.


In the construction industry, waterproofing materials are  sometimes overlooked completely, while others are applying a very think layer or using very low quality waterproofing membrane hence resulting to water damage to the premises. Did you know that water related issues contribute to 80% of a building defects, hence the importance of waterproofing to protect your premises.


Prevent leaks and water damage

Water leaks often leads to destruction of furniture, flooring and water stains on the ceiling or walls.


Poor waterproofing can lead to serious damage to integrity of a building hence making it dangerous to occupy.

Strengthen the building architecture

Waterproofing membrane extend the building’s lifespan by reducing any humidity that could penetrate and cause damage to the property and its content, structure corrosion, rust and rotting.

Protections from mold

Water leakages will damage furniture, carpeting and moisture staining the ceiling or wall and structural issues

Provides a healthier environment

Waterproofing create a cleaner and healthier surroundings from harmful elements especially in walls and ceiling, as these parts can cause fungus and mold growth that leads to various health problems such as asthma, coughs and falling sick often.

Lessen maintenance cost

When waterproofing is done correctly at the initial stage, it will protect your premise from being damaged by water leakage and also reducing the need to do costly repairs and maintenance.


No matter what is the size, location or type of building, waterproofing membrane is a crucial element that is essential to secure the building’s structural integrity. Waterproofing membranes can be applied in various areas, most commonly  waterproofing on flat roofs, balconies, toilets and etc.

Other commons areas such as:-

Concrete water tanks

Basement slab

Flat Roofs


Commercial and industrial building are slightly different than residential since there are much larger and have heavier traffics which resulted in more wear and tear. Here are some points that are crucial in waterproofing applications that can used on commercial, industrial and residential properties.

Foundation Waterproofing

Foundation problem is one of the worst issues that could fall to a building’s structure. The foundation itself is the main element that hold the building in place, and anything that affect this can jeopardize the entire structure itself. Most foundation issues in commercial and residential properties can be associated with water or moisture ingress.


If the soil in the building’s foundation are damp, it may cause the ground to swell and expand resulting to cracks within the structure and may causes damages to equipment. There is a few waterproofing systems that can be used for foundation such liquid applied waterproofing and sheet membranes, and it crucial to ensure proper drainage assimilate in the design

Quality roof waterproofing and insulation usually are often used for commercial properties as large buildings sustain an immense amount of strain. Many components are vulnerable to leaks. Roofs – specially flat roofs which are without proper drainage or concrete roofs are highly prone to leakage. Puddles shaped on a commercial roof due to no proper drainage  can hasten the degradation of current waterproofing system and additionally compromise the integrity and insulation of the ceiling.


Having to  repair or replacing the roof is an exorbitant cost , that is why a better solution is to apply water-proof membranes and enhance the general water drainage of the roof. We recommend looking at our roof top waterproofing membrane system for roof waterproofing because those products are not stricken by ponding or pooling water. but, it’s constantly endorsed to have graded falls to retailers. Concrete roofs are famous in modern architecture, with many residential and industrial premises being built using this approach. despite the fact that concrete is a robust material for roofing, it doesn’t protect the building from leaks.


To avoid concrete cancer or various water associated problems on a concrete roof, it is vitally crucial to apply a membrane which is supplied as a whole system. Chemind water-resistant membrane structures are offering a full range of systems as the waterproofing membrane comes in sheets and liquid – suitable for variety of . those membranes will offer long-term safety in opposition to heat resistance and water preventing structural harm.

Basements, especially aged ones, have a tendency to permit water to seep into the foundation resulting to mold and structural problems. It’s recommended to water-proof the basement from the exterior that allows you to prevent water at its cause. If a membrane has not been laid or it fails, then secondary back-up measures are required something like installing a sump pump, installing negative waterproofing system or installing a dehumidifier. but, the top recommendation is installing a p.c blend membrane sheeting at the exterior partitions. commercial structure are vulnerable to burst water pipes that may result in costly damage if there’s no appropriate  waterproofing in place. Damp may be a continual problem to the internal walls of concrete and brickwork basements, so a dependable prevention and repair strategy is important to save you expensive damages.

Waterproofing retaining walls is a proactive solution to diminish restore work within the long term. retaining walls are frequently introduced in commercial buildings to fully utilize usable space. due to the fact retaining walls keep off soil while there may be a drastic shift of elevation, there is constantly a risk of a crack or shift because of damp, and efficient drainage will be used to offset the strain at the back of the wall. To certainly prevent water build-up, waterproofing membranes used for retaining wall which includes Chemind waterproofing membrane make certain there are no factors of entry for water to get in and will guard from dampness or corrosion.
