TPE waterstop/expansion joint overlap tape is a flexible sealing material based on thermoplastic elastomer (TPE). It combines the high elasticity of rubber with the easy processing of plastic, providing waterproof sealing and displacement adaptation solutions for building expansion joints, construction joints, and deformation joints.

Building Engineering: Basements, underground garages, floor slabs, wall expansion joints.
Municipal Transportation: Tunnel, pipe gallery, bridge, road joint waterproofing.
Water Conservancy and Environmental Protection: Water tanks, sewage treatment plants, dams, reservoirs.
Prefabricated Buildings: Precast component splicing joints, exterior wall panel joints.
Substrate Treatment: Dry, clean, and flat; remove oil, dust, and loose concrete. Overlap Requirements: Overlap length ≥ 5cm, hot welding or special adhesive bonding, ensuring a tight seal.
Installation Methods: Pre-embedded (before concrete pouring), post-installed (after joint formation).
Environmental Requirements: Construction temperature should be ≥ 5℃; preheating is required for low temperatures.
