Waterproofing Contractors: Who Are They and What Do They Do?

February 29, 2024

We are constantly surrounded by water, whether in the form of rainfall or water travelling through the pipes. Unfortunately, this means that our buildings are always at risk of water penetration, which may lead to water leakage, mould growth and decay, and structural weaknesses.

As such, we recommend consulting waterproofing contractors once a problem arises—though their services may be costly to engage, they are critical in the protection of your property. Read on to learn more about waterproofing contractors and what they do.


What Are Waterproofing Contractors?

Waterproofing contractors are individuals trained in the prevention of water and moisture penetration into a building. Ultimately, they aim to keep your building dry, reduce water penetration and damage, and increase the protection and comfort of your property.


What Do Waterproofing Contractors Do? 

Waterproofing contractors offer various services, including (but not limited to):

  • Inspection of properties to determine areas that need waterproofing.
  • Applying water-repelling membranes and coatings to wet areas like roofs and decks.
  • Mitigate water leakages and prevent water from seeping through cracks and faulty joints.


1. Reduce Damage to Your Property

Roof, ceiling, and wall cracks often lead to water leakage problems that spread throughout the building, resulting in a host of issues. For one, the water may damage electrical appliances, in-build furniture, and wooden structures, thus requiring costly replacements and repairs.

Water penetration can also weaken the walls, causing severe damage to the building’s structure, stability, and aesthetics. This is immensely dangerous: if left unattended, parts of the building might collapse, leading to injuries and even fatalities.

Water leakage is not always visible; the problem is often subtle and usually only caught once it has grown exponentially. As such, we recommend monitoring your property carefully for signs of water leakages.


2. Increase Tenant Safety 

Singapore experiences heavy rain and light drizzles all year round. Hence, it is common for buildings to incur weather-induced damages and water leakage problems, resulting in puddles forming around the property.

If you have elderly family members or young children running around, it is critical to engage a waterproofing contractor to prevent the possibility of falls and injuries.


3. Avoid Health Risks 

Damp environments are the perfect breeding ground for fungi, mould, and other bacteria. These organisms may trigger allergic reactions, asthma attacks, and other irritations and infections. Additionally, pools of stagnant water caused by sustained water leakage may encourage mosquito breeding, thus posing serious health problems like dengue fever.

Waterproofing contractors do the important job of creating a barrier between the exterior and interior sections of your home, thus preventing the growth of mould and mildew.


Avoid Health Risks



Water leakages can cause significant problems to your family or tenant’s health and safety. Therefore, it is always best to engage a waterproofing contractor to protect your building from water penetration and damages.
