Injection waterproofing methods are used exclusively for remedial works when the building is experiencing failure. Injection methods involve low-pressure applications and high-pressure injection. Most common concrete waterproofing problems are the result of cracks in the concrete. These cracks can be repaired by applying an epoxy resin to structurally bind the concrete and stop water migration. In this...

WHAT IS TORCH-ON MEMBRANE? Torch-on membrane waterproofing is a type of building waterproofing solution composed of bitumen and a variety of modified polymers. When applied to the surface of a structure, it prevents moisture and liquid from seeping through — which when ignored, can negatively impact the integrity of a building over time. This type of waterproofing...

Polyurethane (PU) Injection grouting is a waterproofing technique that involves creating a polyurethane mixture whereby when this mixture is inserted with pressure into the cracks of a structure, the mixture will react and in turn expand and toughen. It is used to stop water flowing through structural joints and cracks. PU grouting is mainly used...
