Remedial waterproofing of garage – Leak sealing injections and WBE waterproofing system

 

Singapore Waterproofing recently carried out remedial waterproofing on this site in Singapore. Heavy rain regularly flooded the garage. The back wall showed signs of dampness and there was water seeping in through the wall-to-floor joints.  

To treat moisture ingress through the floor/wall joint that runs along the back wall and the garage, we recommended performing high-pressure leak sealing injections of hydrophilic polyurethane of the floor/wall joints.  

The injection system creates a three-dimensional waterproof seal inside the building element by injecting a high-quality hydrophilic polyurethane resin under high pressure. Once the leak sealing injections were completed, the injection ports were removed, and the holes and cracks were plugged with repair mortar. 

To treat the damp wall, we recommended grinding the existing paint off and installing a water-borne epoxy reverse side waterproofing system to the wall. 

Watch the video clip to see how much water is behind the retaining wall near the staircase. During the drilling for the injection ports, there was a lot of water coming out of the wall, especially in the corner near the stairs. In addition to Singapore Waterproofing’s proprietary leak sealing process, our on-site leak sealing specialists used a few additional steps. 

Please note that in cases where the water-borne epoxy waterproofing system is installed to a concrete floor, we recommend installing a flooring system (i.e. tiles or carpet) to protect the moisture barrier. The reason is that the WBE moisture barrier is susceptible to damage from UV-light and abrasive damage caused by foot traffic and objects (such as furniture) being dragged across its surface.

 

Give us a call to discuss the best protective treatment application for your vertical and horizontal surfaces to help you choose the appropriate product and methods to protect them and how to best prepare the surface before installation for best performance.

If you have any issues with water ingress, rooftop leaks, leaking balcony, leaking basement, wet lift pit, cracking concrete slabs, structural cracks, concrete deterioration, spalling concrete, concrete cancer, deteriorated joints, moisture, seepage, efflorescence, rising damp and/or high-flow active leaks in concrete structures, we would be happy to assist you. You are welcome to contact us with any questions that you may have.
