Damp proof or water proofing Tunnel Linings?

Lining a tunnel to prevent water ingress?

Solution:

Newton System 500 has been used extensively to stop water ingress in tunnels used by the London Underground System. By using Newton 508, a dry-lined finish can be achieved in the tunnel. However, if a rendered system is required, then Newton 508 Mesh (with its built-in mesh) is the membrane to be used. In both instances the membrane and fixing plugs would need to be sealed with our bituminous rope or tape and the joints over taped.

To comply with BS8102, the depressurized Water being channeled behind the membrane can be removed by the use of Newton Basedrain incorporated at the wall/floor junction which acts as a collection point for water which can then run to a natural drainage point or to a Newton Titan sump/pump chamber.
