PU (polyurethane) grout injection is a repair method where polyurethane grout is injected into damaged areas of a manhole. The grout expands and hardens to create a strong, durable bond that restores structural integrity — sealing cracks, joints, and water ingress points without excavation.
Manholes deteriorate due to age, wear and tear, ground movement, chemical attack from sewer gases, tree root intrusion, and groundwater ingress. Over time these factors weaken the structure and can lead to leaks, collapse, or safety hazards.
PU grout injection creates a durable structural seal that typically lasts decades depending on the operating environment and severity of the original damage. The repair restores the manhole to its optimal structural condition.
Yes. PU grout injection minimises downtime and surface disruption compared to traditional dig-and-replace methods. The repair is performed through the existing manhole access without excavation, allowing for quick and long-lasting results.
Yes. Every manhole repair includes pre-work assessment, post-work inspection, and full compliance documentation. PPT operates under DBYD certification and Western Australian safety standards on every project.
