Our Roof Waterproofing system provides one of the most cost-effective methods for making a new or existing reinforced concrete (R.C.) flat roof waterproof. When correctly installed and maintained, these roofs will have a longer lifespan, which can then save you roof replacement costs.
Some of our roof waterproofing methods include:
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 an 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 Suggested Procedure
Refurbishment – when an R.C. flat roof is coming to the end of its life, roof waterproofing is often required to seamlessly and fully bond to the substrate. It is ideal for use over existing roofing, including single ply membranes, profiled metal, or fiber cement.
Repair – when an existing roofing material has failed, it is often caused by a deteriorating membrane. With concrete roof repair, an overlay can be applied to a single ply membrane, which provides a cost-effective solution with a reliable bonding characteristic.
Our trusted 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 waterproofed.
Our trained staff will propose the best-fit waterproofing method after the assessment and explain our procedure of waterproofing on the spot.
