KG conforms to all <br />requirements of this method statement <br />2.2 Materials <br />A. TPE (thermoplastic elastomer) <br />2.3 Performance Criteria <br /> <br />AQUAFIN-CJ6 has the following properties: <br /> <br />Basis: <br />TPE <br /> <br />Format: <br />quadratic and flexbile <br /> Colour: <br />red <br /> <br />Density: <br />1.25 g / m³ <br /> <br />Hardness per Shore A in accordance <br /> <br />with DIN 53505: 37 <br /> <br />Thickness: 5 mm <br /> <br />Width: 20 mm <br /> <br />Start of swelling on <br /> <br />water contact: <br />approx. 6 hours</p> <p>1/2</p> <p>06/20</p> <p> Swelling capacity <br />(demin. Water) approx. 50 % after 2 hours <br /> <br />approx. 460 % after 24 hours <br /> <br />approx. ≥ 700 % after 8 days <br /> <br />Expansive pressure: approx. 1.06 N/mm² <br /> Water-impermeability <br /> <br />after installation <br /> <br />(0.25 mm joint): 2 bar <br /> Toxicity: <br />none <br /> <br />Reaction to fire in accordance <br /> <br />with EN 13501: normal inflammability <br />(construction class E) <br /> <br />Packaging: <br />rolls of 40 linear meters</p> <p>Part 3 – Execution <br />3.1 General <br />AQUAFIN-CJ6 is used as a construction joint waterstop <br />in concrete construction. <br />3.2 Application: <br />Substrate preparation: <br />The substrate must be load-bearing, mostly flat and have <br />a closed surface texture. It must be free from gravel <br />pockets, cavities, gaping cracks, dust and be free from <br />adhesion inhibiting substances. Laitance layers are to <br />be removed, mechanically abraded (sand blasted) as <br />necessary. During the application of AQUAFIN-CJ6 the <br />substrate may be matt damp. The formation of puddles is <br />not permitted.</p> <p>begin the concreting process for at least 8 hours after <br />bonding. Alternatively, AQUAFIN-CJ6 can also be <br />fastened with steel nails (min. 5 nails/m). When doing <br />so, it is necessary to ensure substrate contact pressure <br />covering the whole area. Avoid looping or hollow layers. <br />Waterstop connections can be made by overlapping by <br />5 cm or by butt jointing. The waterstops must be placed <br />tightly together to prevent gaps. Butt jointed waterstops <br />must be covered by a separate section of waterstop with <br />a 3 cm overlap to both sections. <br />Notes: <br />• It is essential to store the waterstop dry. <br />• Waterstops must lie flat and planar on the concrete. <br />There must be no contaminants beneath the waterstop. <br />• Protect the waterstop from moisture until the concrete is <br />poured. <br />• Before commencing the concreting process visually <br />inspect the waterstop. Heavily swollen waterstop tape <br />is unsuitable and must be removed. <br />• Waterstops are not suitable for movement joints. <br />• Follow current relevant regulations and data sheets</p> <p>Product application: <br />It is essential that there is at least > 8 cm coverage <br />of concrete from the side exposed to water. Bond <br />AQUAFIN-CJ6 with a mounting adhesive suitable for <br />waterstops – e.g. AQUAFIN-CA. <br />Completely cover the prepared substrate with the <br />mounting adhesive and press the AQUAFIN-CJ6 into <br />the adhesive until it oozes out from beneath.
