Overview
Abandoned pipelines can create serious safety hazards and environmental problems.
An abandoned pipe effectively creates an underground void, which can cause subsidence, soil destabilisation, and water ingress. This can increase the risk of residual fluids leaking into public areas and the ground collapsing.
In the interest of public safety and satisfying legal requirements, it is vital that councils and asset owners decommission abandoned pipelines and fill properly, quickly, and safely.
Terefil® from Mainmark is a lightweight, engineered void fill solution for pipes of every size. It’s a unique, flowable fill material that can fill massive pipelines and concrete culverts quickly and cost-effectively.
