The Maspion WSF Series PVC Waterstops, including the WSF 150 and WSF 200, are high-quality PVC waterstops designed to prevent water penetration through construction joints in reinforced concrete structures. Manufactured from durable, flexible PVC, their ribbed profiles create a strong mechanical bond with the surrounding concrete, providing a reliable and long-lasting watertight seal. Designed for construction joints where two concrete pours meet and little or no expansion movement is expected, the WSF Series is ideal for retaining walls, water-retaining structures, and below-ground construction. The WSF 150 is suited to residential and light commercial projects, while the wider WSF 200 is recommended for larger commercial, industrial, and civil engineering applications. Suitable for both horizontal and vertical installations, the WSF Series is commonly used in basements, reservoirs, water tanks, swimming pools, tunnels, culverts, and wastewater treatment facilities.
