Tunnel refurbishment/leak sealing

Having undertaken several major tunnel refurbishment projects, experience shows us that most underground tunnels suffer from water ingress.

This has led us to develop our own specialist leak-sealing division.

How does it work?

Our leak-sealing process uses a revolutionary two-component acrylic product that’s injected into concrete structures and masonry, and through tunnel bolts. This liquid follows the contours of the fissure, expands, and then solidifies to create an impenetrable seal.


 Fine clean

As a result, we are one of the UK’s largest leak-sealing contractors.

Underground Spaces

Forest Environmental’s proprietary leak-sealing procedures also mean that leaky basements and storeys below the water level can be transformed into watertight, dry areas. This enables you to make good use of what was redundant underground space to provide:

  • car parking
  • archive/ storage areas
  • warehousing
