Polyurethane (PU) Injection

PU injection also known as polyurethane injection is a waterproofing technique that expand injected polyurethane to prevent water from flowing through, and to fill and seal cracks and voids typically in concrete. Other than its quick installation, is it also highly viable, effective and useful solution that can withstand any weather and climate.

Pu injection is used to repair most water leakage problems in walls or ceilings. We usually drill a hole in the problem area, then pump PU into the hole. The chemical composition is then triggered to expand and will fill up the hairline cracks. When the chemical composition contacts with the water, it will crystalize and expand and fill up all the cracks. Usually, there will be a few holes being drilled into the wall or ceiling, to ensure all the possible crack areas are covered.

It is mostly used due to its low construction cost compared to other waterproofing methods. It can be used for coating, maintenance, emergency repair and insulation. Other than that, it is less time consuming due to its chemical components that quickly dries and less damages done on walls to fix your leakage problem as it only drills a hole to fill up. PU injection also have UV ray protection that protects your building from sun exposure, also susceptible to wear and tear and requires minimal maintenance.
