IZOMAX® STB PVC-V
IZOMAX® STB PVC-V is a flexible waterstop based on modified PVC with a thin cross-section and anchoring ribs, installed within the concrete section in construction (cold) joints of reinforced concrete structures. With widths of 15–20 cm and thicknesses of 3–4 mm, it provides a light and economical sealing solution for structures exposed to low and medium water pressure.
Areas of Application
• Building basements and underground car parks
• Retaining walls and ground-bearing slabs
• Water tanks exposed to low water pressure
• Irrigation canals and small-scale water structures
• Successive pour joints in walls and slabs
Advantages
• Provides an economical and lightweight solution with its thin cross-section
• Easy to place in densely reinforced areas
• Anchoring ribs key the waterstop into the concrete and prevent pull-out
• Can be welded easily and homogeneously on site with heating-element (hot plate) welding equipment
• Produced from high-quality modified PVC for a long service life
• Resistant to ageing, alkaline environments and natural groundwater
• Forms a continuous sealing system with T, L and X junction pieces
