PVC Waterstops for Internal & External Construction Joints
PVC Waterstops (Betostop ECJ / EEJ / ICJ / IEJ) are high-grade extruded flexible PVC sealing profiles designed for embedded installation in concrete expansion and construction joints to form a durable watertight barrier against high hydrostatic head.
Product Overview
This product range offers advanced material performance and long-term durability. Formulated to meet high standards of protection and reliability under various site conditions. PVC Waterstops (Betostop ECJ / EEJ / ICJ / IEJ) are high-grade extruded flexible PVC sealing profiles designed for embedded installation in concrete expansion and construction joints to form a durable watertight barrier against high hydrostatic head.
Best-fit Applications
- • Water-retaining structures including water tanks, reservoirs, and pools
- • Water-excluding structures including basements, tunnels, and subways
- • Expansion and construction joints in floor slabs, walls, and podium decks
- • Civil engineering infrastructure and sewage treatment plants
Technical Benefits
- • High-tensile extruded virgin PVC compound with long-term elasticity
- • Withstands high hydrostatic water head pressure
- • Simple heat-welding on site for continuous watertight joint network
- • Resistant to acidic, alkaline, and saline groundwater environments

Application Guidelines & Installation Method
Step 1: For reinforcement mesh, ensure a clean, sound substrate, cut and position the mesh to the approved detail, provide required overlaps, secure it against movement and apply the specified waterproofing or coating layer.
Step 2: For PVC waterstops, position centrally along the joint, secure with suitable clips or fixings, maintain continuous alignment, avoid damage and ensure every joint is correctly welded and watertight.
