It is red in colour and measures 20 mm wide by 5 mm in thickness. <br />1.2 An ancillary item that is available for use with the product, and which is included in this Certificate is: <br />• AQUAFIN-CA – used to secure AQUAFIN-CJ6 to the concrete substrate.</p> <p>2 Manufacture <br />2.1 The compound is manufactured by a batch blending process and then extruded into strips and cut to length. <br />2.2 As part of the assessment and ongoing surveillance of product quality, the BBA has: <br />• <br />• <br />• <br />• <br />• <br />•</p> <p>agreed with the manufacturer the quality control procedures and product testing to be undertaken <br />assessed and agreed the quality control operated over batches of incoming materials <br />monitored the production process and verified that it is in accordance with the documented process <br />evaluated the process for management of nonconformities <br />checked that equipment has been properly tested and calibrated <br />undertaken to carry out the above measures on a regular basis through a surveillance process, to verify that the <br />specifications and quality control operated by the manufacturer are being maintained.</p> <p>2.3 The management systems of Schomburg GmbH & Co. KG have been assessed and registered as meeting the <br />requirements of BS EN ISO 9001 : 2015 by TÜV Rheinland Cert GmbH International (Certificate 01 100 6383/05).</p> <p>3 Delivery and site handling <br />3.1 AQUAFIN-CJ6 is supplied in 40 m rolls, which are packaged in a carton containing 5 rolls and having a gross weight <br />of approximately 25 kg. Cartons can be supplied on pallets containing a maximum of 20 cartons. <br />3.2 The product must be stored under cover, clear of the ground and protected from UV, moisture, frost and other <br />sources of contamination at a temperature of between 5 and 35°C. When stored correctly in unopened packs, <br />AQUAFIN-CJ6 will have a shelf life of at least two years from the date of manufacture. <br />3.3 The Certificate holder has taken the responsibility of classifying and labelling the product under the CLP Regulation <br />(EC) No 1272/2008 on the classification, labelling and packaging of substances and mixtures. Users must refer to the <br />relevant Safety Data Sheet(s).</p> <p>Page 3 of 7</p> <p>Assessment and Technical Investigations <br />The following is a summary of the assessment and technical investigations carried out on AQUAFIN-CJ6.</p> <p>Design Considerations <br />4 Use <br />4.1 The product is satisfactory for use as part of a Type B (structurally integral) protection (as defined in BS 8102 : <br />2009) to waterproof construction joints and penetrations in underground waterproof reinforced concrete structures. <br />4.2 The product is not suitable for use in movement joints, eg expansion joints. <br />4.3 The product swells on contact with water and must be fully confined within the concrete structure to form an <br />effective seal. <br />4.4 The unconfined AQUAFIN-CJ6 will expand by up to 550 % by volume in neutral pH water. The expansion under <br />alkaline or acidic water conditions will be less, but will be adequate to enable the product to form an effective seal <br />when fully confined. <br />4.5 The product will shrink on drying, but will re-hydrate on wetting and re-swell to provide an effective seal. <br />4.6 The ability of the product to expand and form an effective seal can be adversely affected by the groundwater <br />chemistry, especially saline conditions. A detailed study of this aspect must be carried out to establish the presence of <br />any contamination. The Certificate holder must be consulted for advice on specific applications, service conditions and <br />groundwater chemistry. <br />4.7 The product will develop significant pressure when confined within a concrete structure and must be covered by at <br />least 80 mm of concrete from each edge to avoid damage to the concrete.</p> <p>5 Practicability of installation <br />5.1 The product must only be installed by contractors who have been trained by the Certificate holder. <br />5.2 To avoid premature swelling, the product must be protected from contact with water until enclosed in the <br />structure and must not be placed during rain or when rain is forecast.</p> <p>6 Resistance to water pressure <br />6.1 When confined, the product forms an effective barrier to water under hydrostatic pressure from the <br />ground in water-resistant reinforced concrete construction joints. <br />6.2 The product was tested at a maximum hydrostatic water pressure of 4.0 bar and remained watertight. <br />6.3 An appropriate safety factor must be applied to the maximum water pressure given in section 6.2 and the use of <br />additional waterproof protection should be considered, depending on the specific use and risks associated with any <br />particular structure.</p> <p>7 Maintenance <br />As the product is confined within the structure and has suitable in-situ durability, maintenance is neither possible nor <br />required.</p> <p>Page 4 of 7</p> <p>8 Durability <br />8.1 AQUAFIN-CJ6 will function effectively as a waterstop and provide an effective barrier to water under <br />hydrostatic pressure for the life of the structure in which it is incorporated.</p> <p>8.2 The durability of the product may be affected if dislodged or damaged during or following installation, therefore <br />care must be taken to ensure that the product remains in position and is not dislodged when concrete is poured over it, <br />nor damaged during subsequent actions, eg vibration.</p> <p>Installation <br />9 General <br />9.1 AQUAFIN-CJ6 must be placed onto smooth and dust-free concrete surfaces. Uneven and irregular surfaces must be <br />levelled using a suitable mastic. The Certificate holder must be consulted for suitable products, the performance of <br />which are outside of the scope of this Certificate. <br />9.2 Dust, dirt and other debris must be removed using a stiff brush and/or suitable mechanical means.</p> <p>10 Procedure <br />Placing <br />10.1 AQUAFIN-CJ6 is unrolled and placed onto the concrete surface to sit centrally between the inner and outer rows <br />of the reinforcing bars. <br />10.2 A minimum of 80 mm concrete coverage must be ensured around all edges. <br />10.3 Roll ends must be placed to have an overlap of ≥50 mm and pressed firmly together, or by butt jointing. Butt <br />joints must be covered by a separate section of waterstop with a 30 mm overlap to both sections. <br />Fixing <br />10.4 AQUAFIN-CA can be used on clean substrates, wire brushed to remove all contamination. A 10 mm bead of <br />AQUAFIN-CA is gunned onto the substrate, and the product firmly pressed into the adhesive. <br />Enclosing <br />10.5 Prior to enclosing AQUAFIN-CJ6, the placed product must be inspected for damage and premature swelling. If <br />damaged and/or swollen, the product must be replaced at this stage. <br />10.6 Concrete is then poured to enclose the product, compacting well around the waterstop but taking particular care <br />not to dislodge or damage the strip during the process.</p> <p>Technical Investigations <br />11 Tests <br />Tests were carried out on samples of AQUAFIN-CJ6 and the results assessed to determine: <br />• <br />• <br />• <br />• <br />•</p> <p>product characteristics <br />resistance to hydrostatic water pressure <br />unrestricted swelling characteristics under alkali, neutral and acidic water conditions <br />effect of wet/dry cycles on swelling characteristics <br />load developed when restrained. <br />Page 5 of 7</p> <p>12 Investigations <br />The manufacturing process was evaluated, including the methods adopted for quality control, and details were <br />obtained of the quality and composition of the materials used.</p> <p>Bibliography <br />BS 8102 : 2009 Code of practice for protection of below ground structures against water from the ground <br />EN ISO 9001 : 2015 Quality management systems — Requirements</p> <p>Page 6 of 7</p> <p>Conditions of Certificate <br />Conditions <br />1.
