KG conforms to all <br />requirements of this method statement.. <br />2.2 Materials <br />A. Sodium bentonite embedded in a matrix of high <br />molecular weight poly-isobutylene rubber as well <br />as special filters and additives. <br />2.3 Performance Criteria <br />AQUAFIN-CJ4 has the following properties: <br /> <br />Basis: <br />bentonite <br /> <br />Format: <br />square-edged and flexbile <br /> <br />Colour: <br />black / grey <br /> <br />Density: <br />730 g / m <br /> <br />Thickness: <br />18 mm <br /> <br />Width: <br />24 mm <br /> Swelling capacity <br />(demin. water): approx. ≥ 500 % after 8 days <br />Water-impermeability <br />after installation <br />(0.25 mm joint): 2 bar <br /> Toxicity: <br />none <br /> <br />Packaging: rolls of 5 linear meters; 4 rolls to <br />a box</p> <p>1/2</p> <p>06/20</p> <p>Part 3 – Execution <br />3.1 General <br />AQUAFIN-CJ4 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-CJ4 the <br />substrate may be matt damp. The formation of puddles is <br />not permitted.</p> <p>• 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-CJ4 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-CJ4 into <br />the adhesive until it oozes out from beneath. Do not <br />begin the concreting process for at least 8 hours after <br />bonding. Alternatively, AQUAFIN-CJ4 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 />•W <br /> aterstops must lie flat and planar on the concrete. <br />There must be no contaminants beneath the waterstop.</p> <p>The rights of the buyer with regard to the quality of our materials are based on our terms and conditions of sale and delivery.
