Bentonite Waterproofi ng Liner
CEMtobent
Submerged tunnel crossingunder Bjorvika FjordOsloNorway
Advantages
CEMtobent DS
CEMtobent DS / DoubleSealconsists of two complementarycomponents:
the primary sealingis a 3D-PE sheet
the secondary sealingis a a high quality geocompositeclay liner (GCL)
CEMtobent CS-Plus
CEMtobent CS-Plus / CombiSeal-Plus consists of three complementary components:
the primary sealingis a 3D-PE-sheet
the secondary sealingis a a high quality geocompositeclay liner (GCL)
An additional PE coated linerthat is radon and root resistantis bonded to the CEMtobent CSmembrane.
Two designs
High resistant, easy to handle and eco-friendly.
Effective rain-protection.
Can be installed independent of temperatures and weather conditions.
No welding required.
Continuous quality controls.
Self-healing properties if damaged during installation.
Shrinkage cracks in the concrete structure can be sealed.
The large, respectively variable width allows or little loss of material at the overlappings.
CEMtobent can be used in areas where fl owing groundwater is expected.
CEMtobent CS-Plus is root-resistant and radon-tight, even under dry conditions!
CEMtobent is a bentonite-based membrane specially designed for waterproofi ng and protection of below ground concrete structures and tunnels.
The CEMtobent membrane is a strong and robustsystem that is suitable for use where working conditions are diffi cult, giving you the confi dence and assurance that the waterproof membrane will function correctly.An additional feature is the special rain protectionliner on the CEMtobent membrane that allows it to beinstalled in all types of weather.
The active ingredient in the CEMtobent membrane is a high quality sodium-bentonite powder, which is capableof swelling up to 8 times its original dry volume. If ground water comes into contact with the installed CEMtobent membrane, the sodium-bentonite powder swells and fi lls any voids or cracks in the concrete, producing a watertight structure.
The freshly placed concrete bonds with the CEMtobentmembrane; therefore, the possibility of any watercirculation between the concrete and the membrane iseliminated.
