PU grouting is a specialized 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 the water seepage,  for example, from the underside of the leaking walls or the lower floor ceiling for issues involving upper and lower floor neighbors or in inter-floor water leakages. A pre-drilled hole will be prepared on the underside of the ceiling, and the PU grout will be injected using low/high pressure. The grout will then expand to fully fill up the void, crack or space that is caused by the water damage. This PU injection can be used for concrete cracks or expansion joints that are actively leaking.

​

We specialize in PU injection to seal joints in concrete, screed or masonry as well as water-bearing cracks. We can also help with the repair of damaged false ceiling, including the opening and resealing up of broken or damaged false ceiling.

 

PU Grouting Concrete Crack Injection Technique:

 

Cracks in concrete happen overtime due to environmental issues such as thermal movement, drying shrinkage and other causes like nearby construction works or renovation works. If its not severe, it will be a minor problem and they will cause no instant issues or problems. But after some time, these minor and small cracks often become bigger problems and huge headaches, where water damage causes structural problems including reduced structural integrity due to water seepage.

​

We provide comprehensive PU injection / PU grouting services, using modern technology and the best equipment to use solutions for filling up the gaps, voids and cracks in structures and bonding concrete and other materials permanently.
