LONGSEAL
Longseal self adhesive membranes offer excellent structural waterproofing for new construction projects. Depending on the engineering requirements and project specifications a wide range is available in varying thicknesses and mechanical strengths. Specialised membranes are also available for methane barrier protection, and for applications where membranes may be in direct contact with potable water. Roll sizes and weights can be altered to suit specific requirements.

In this case Longseal 100 was manufactured to suit the tunnel dimensions in line with the contractors application method.
