Our Waterproofing Methods
Prima Seal Waterproofing Singapore uses a unique Flood Infusion Treatment that utilizes waterproofing chemicals that is waterborne and dampness sealing for concrete and masonry substrates. Also known as chemical infusion waterproofing, our specially formulated solution is manufactured from a blend of Inorganic and Organic Polymers. It achieves both surface and in-depth sealing by both film formation and crystallisation. It involves no dust, smell, noise, drilling, hacking, and removal of existing tile finish.
PU Grouting / PU Injection is a specialised technique that involves the injection of expanding polyurethane to stop any water flowing down or through cracks or to fill voids under slabs, concrete joints or behind concrete walls and joints. This method is very useful and effective when used on the underside or negative side of a water seepage.
Fibreglass Acrylic Waterproofing System is considered to be one of the most popular and sought-after waterproofing methods. Due to the various features and attributes of fibre glass, this product is used in various waterproofing applications like on balconies or concrete roofs.
Torch On Membrane Waterproofing is a type of waterproofing method used in various places like flat roofs and balconies, just to name a few. It creates a comparatively strong membrane layer that is made up of polymers and bitumen that protects that layer against moistures and dampness. Due to this property, torch on membrane can effectively stop water from pooling on certain parts of a surface.
