Tunnel Construction is certainly a challenge for the engineer and the performance of the structure highly depends on the design, material and the construction method applied. Underground structures need to be made watertight to withstand the salty underground water encountered in most part of the GCC region.

The waterproofing of a tunnel structure is a key factor and has a major impact on the service lifetime of the tunnel. HDPE geomembrane liners are probably the most suitable waterproofing system as their wide roll dimensions allow for faster installation and less joints. Welded HDPE joints (by double wedge or extrusion welding) are considered strong points and are 100% tested, thus guaranteeing a leak free application. The Engineering team of BMC Gulf will assist you to choose the right waterproofing system you’re your project. With a significant project experience in waterproofing of tunnel structures we provide you with the right solution from the design stage to material supply and installation.
