The system has been <br />assessed as a flexible, hydrophilic waterstop for use at construction joints and penetrations in underground reinforced <br />waterproof concrete structures.</p> <p>ASSESSMENT <br />System description and intended use <br />The Certificate holder provided the following description for the system under assessment. <br />AQUAFIN-CJ6 is a flexible hydrophilic waterstop. It is red in colour and measures 20 mm wide by 5 mm in thickness. <br />Ancillary Items <br />AQUAFIN-CA is an adhesive used to secure AQUAFIN-CJ6 to the concrete substrate which is essential to use with the <br />system and has been assessed with the system. <br />Applications <br />The system is satisfactory for use as part of a Type B (structurally integral) protection (as defined in BS 8102 : 2022) to <br />waterproof construction joints and penetrations in underground reinforced waterproof concrete structures. <br />The system has not been assessed for use in movement joints.</p> <p>System assessment – key factors <br />The system was assessed for the following key factors, and the outcome of the assessments is shown below. <br />Conclusions relating to the Building Regulations apply to the whole of the UK unless otherwise stated.</p> <p>1 Mechanical resistance and stability <br />Not applicable.</p> <p>2 Safety in case of fire <br />Not applicable. <br />BBA 20/5741 PS3 Issue 2</p> <p>Page 3 of 9</p> <p>3 Hygiene, health and the environment <br />Data were assessed for the following characteristics. <br />3.1 Weathertightness <br />3.1.1 Results of weathertightness tests are given in Table 1. <br />Table 1 Weathertightness <br />System assessed <br />AQUAFIN CJ-6</p> <p>Assessment method <br />Unrestrained swelling and recovery <br />BBA test method</p> <p>Requirement <br />No detrimental <br />effect</p> <p>Result <br />Pass</p> <p>AQUAFIN CJ-6</p> <p>Restrained load developed when swollen <br />BBA test method</p> <p>Value achieved</p> <p>1008 N achieved <br />after 10 days</p> <p>AQUAFIN CJ-6</p> <p>Resistance to hydrostatic pressure <br />PG-FBB Part 1 <br />Exposure to 4 bar of water pressure for 28 days</p> <p>No water <br />penetration</p> <p>Pass</p> <p>3.1.2 The unconfined system, in neutral pH water at +5°C and +23°C, will expand by up to 550% and 1000% by volume, <br />respectively. <br />3.1.3 The expansion of the system in an alkaline solution of calcium hydroxide with a pH up to 12.0 and an acidic <br />solution of sulphuric acid with a pH down to 5.0 will be less than that in neutral water, but will be adequate to enable <br />the system to form an effective seal when fully confined. <br />3.1.4 The system will shrink on drying, but will re-hydrate on wetting without detriment to their ability to swell. <br />3.1.5 On the basis of data assessed, the system forms an effective barrier to water under pressure from the ground. <br />3.1.6 The ability of the system to expand and form an effective seal can be adversely affected by the groundwater <br />chemistry, eg saline conditions, and the system has not been assessed for use under conditions other than those <br />detailed in Table 1. The Certificate holder must be consulted for advice on specific applications, service conditions and <br />groundwater chemistry, but such advice is outside the scope of this Certificate. <br />3.1.7 The system will develop significant pressure when confined within a concrete structure and must be covered by <br />at least 80 mm of concrete from each edge to reduce the risk of damaging the concrete. <br />3.1.8 An appropriate safety factor must be applied to the maximum water pressure given in Table 1 and the use of <br />additional waterproof protection must be considered, depending on the specific use and risks associated with any <br />particular structure.</p> <p>4 Safety and accessibility in use <br />Not applicable.</p> <p>5 Protection against noise <br />Not applicable.</p> <p>6 Energy economy and heat retention <br />Not applicable.</p> <p>7 Sustainable use of natural resources <br />Not applicable. <br />BBA 20/5741 PS3 Issue 2</p> <p>Page 4 of 9</p> <p>8 Durability <br />The potential mechanisms for degradation and the known performance characteristics of the materials in the system <br />were assessed. <br />8.2 Service life <br />8.2.1 Under normal service conditions, the system will have a life equivalent to the structure in which it is <br />incorporated, provided it is designed, installed and maintained in accordance with this Certificate and the Certificate <br />holder’s instructions. <br />8.2.2 The durability of the system may be affected if it is dislodged or damaged during or following installation; <br />therefore, care must be taken to ensure that the system remains in position and is not dislodged when concrete is <br />poured over it, or damaged during subsequent actions, eg vibration.</p> <p>PROCESS ASSESSMENT <br />Information provided by the Certificate holder was assessed for the following factors:</p> <p>9 Design, installation, workmanship and maintenance <br />9.1 Design <br />The system swells on contact with water and must be fully confined within the concrete structure to form an effective <br />seal. <br />9.2 Installation <br />9.2.1 Installation instructions provided by the Certificate holder were assessed and judged to be appropriate and <br />adequate. <br />9.2.2 Installation must be carried out in accordance with this Certificate and the Certificate holder’s instructions. A <br />summary of instructions and guidance is provided in Annex A. <br />9.2.3 Installation must be carried out in accordance with the relevant requirements of BS 8102 : 2022. <br />9.2.4 To avoid premature swelling, the system 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. <br />9.2.5 The system is intended for use on a sound and well-compacted concrete substrate. The substrate must be: <br />clean and free from surface contamination <br />dry <br />at a temperature between +5 and +35°C <br />free of dust, dirt and other debris (if present, must be removed using a stiff brush and/or suitable mechanical <br />means) <br />• smooth. Freshly placed concrete can be smoothed with a wooden batten to form a shallow rebate along which the <br />system can be placed. <br />• <br />• <br />• <br />•</p> <p>9.2.6 A minimum of 80 mm concrete coverage must be ensured around all edges. <br />9.2.7 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.</p> <p>BBA 20/5741 PS3 Issue 2</p> <p>Page 5 of 9</p> <p>9.3 Workmanship <br />Practicability of installation was assessed by the BBA, on the basis of the Certificate holder’s information.
