What is PU Grouting?
PU grouting, also called polyurethane injection grouting, involves injecting polyurethane resin into cracks or voids in concrete structures. This resin expands upon contact with water, filling gaps and creating a watertight seal. The hardened resin strengthens the structure and prevents further water infiltration.
This technique is especially suitable for situations where conventional repairs may be disruptive or ineffective. PU grouting is commonly applied in basements, swimming pools, walls, ceilings, retaining walls, and honeycombed concrete structures. Its versatility makes it one of the most sought‑after waterproofing solutions in Singapore.
Signs You Need PU Grouting Services
Engaging a roof repair contractor for PU grouting early can prevent costly damage. Common signs that PU grouting may be required include:
- Visible cracks in walls, ceilings, or floors
- Water seepage through joints or voids
- Persistent damp patches or water stains
- Leaks in basements, swimming pools, or retaining walls
- Honeycombed concrete allowing water penetration
Ignoring these signs can lead to worsening structural problems and higher repair costs. PU grouting addresses these issues at the source, ensuring long‑term protection.
