Conventional plasticised PVC waterstops do not offer the long term resistance to a broad range of aggressive chemicals, solvents and hot petroleum oils. Typical applications are: „ Primary and secondary containment „ Refineries „ Mining facilities „ Fueling depots „ Chemical plants and acid storage Advantages „ Outstanding chemical resistance to a range of deleterious fluids such as acids, oils and other aqueous solutions (Alcohol, Ketones, Glycols, Esters, & Hydrocarbons) „ Excellent retention of physical properties at elevated temperatures „ Superior ozone and weathering resistance „ No harmful plasticisers (phthalates) „ EPA compliant certificate (NSF standard 61) „ Range of profiles installation „ Prefabricated intersections Description Earth Shield is used as a fluid tight diaphragm embedded in concrete, across and along the joint in what is considered a standard traditional installation method. Unlike polyvinyl chloride (PVC) waterstop Earth Shield contains no plasticiser, stabiliser or filler to leech out when exposed to chemicals, fuels and aggressive industrial fluids. Detailed performance listing is available on request. It can also withstand exposure to high and low temperatures (-60°C to 135°C) without detrimental effect. Earth Shield has chosen a fully cross linked TPV (Thermoplastic Vulcanizate) as its standard elastomer compound which provides superior mechanical properties and retention as well as chemical resistance. Design Criteria Profile selection should be based on the detailed drawings and specification for contraction, expansion and construction joints. Ribbed centerbulb - accommodates lateral, transverse and shear movement and with its long fluid-flow path is the most versatile of the waterstop profiles available. Base Seal or Rear Guard - waterstops are ideal for flat pavement jobs such as runways and large containment slab’s etc. Properties Test Method Results Shore A hardness (5 sec): ASTM D2240 90± at 25°C Tensile strength: ASTM D412 15.9 MPa Ultimate elongation (at break) 100% ASTM D412 530% Modulus: ASTM D746 16.9 MPa Tear strength: ASTM D624 278 pli @ 25°C Compression set: ASTM D395 45% at 100°C Brittle point: ASTM D746 -25°C Ozone resistance: ASTM D1171 Passed, no cracking at 450 pphm Chemical resistance: ASTM D471 Meet or exceed specific testing standards July 2008
