PU Injection Grouting.


What is PU injection grouting


PU injection Grouting (also called polyurethane grouting) is one of the popular techniques that is used for waterproofing construction industries. Nowadays, PU injection grouting is an inevitable content in the commercial and residential building sector. Today the major threat in the construction field is water leaking issues. In these modern times, we have lost our planetary energy balance and our climate is changing day by day.

Nowadays, We are facing major threats are floods, earthquakes, soil erosion, etc. Water leaks through the roofs, walls, and even through floors are unpredictable and it is a complicated issue to rectify this. Sometimes we don't care about small water leaks in our homes. When we plugged one gulp, then water will surely find another way to get in. Maybe a small water leak will lead to the complete demolition of our homes.

Polyurethane chemical structure


PU injection grouting is the most effective and reasonable solution to rectify water leaks. Polyurethane is a large molecule polymer combined with carbamate links. 

Polyurethane reaction with water

Polyurethane foam quickly reacts with the water creates a hydrophobic or hydrophilic expansion. After the expansion, it will become rigid and solid form. This procedure is used in PU injection grouting. The grout is injected into the void using a gun, causing a tight, rigid form inside the void.
