Waterproofing Concrete roof

Our Roof Waterproofing systems provides one of the most cost effective methods for making a new or existing roof waterproof. Correctly installed and maintained they can provide a long term life and save up on roof replacement costs.

Most roofs in Singapore are constructed using reinforced concrete which is known to have pores or capillary tracts. Depending on the design strength, density and installation techniques, the number of pores can vary. These pores are interconnected within the concrete and water will penetrate through such capillary tracts aided by osmotic effect.

Concrete is known to be inherently weak in tension; cracks and voids can also form due to thermal expansion, contraction and shrinkage. As a result, water will seep through these voids. Therefore, roof waterproofing is required to keep the roof water-tight since they are exposed to the weather.


Our suggestion

Refurbishment – when roof is coming to the end of its life, our roof waterproofing system applied is seamless and fully bonds to the substrate, so is ideal for used over existing roofing, including single ply membranes, profiled metal or fiber cement.

Repair – where an existing roofing material has failed, if an existing membrane has failed, for example a single ply membrane, applying an overlay can be a very cost effective solution, and its bonding characteristic make it much more reliable.

Our waterproofing specialist will inspect the area with our equipment and assess the seriousness of the roof leakage before giving our professional opinion on the areas that need to be waterproof.

Our trained staff will propose the best fit waterproofing method after the assessment and explain our procedure of waterproofing on the spot.
