Assessment and Technical Investigations The following is a summary of the assessment and technical investigations carried out on Hey Di K11. Design Considerations 3 Use 3.1 Hey Di K11, used as a two-coat application in the proportions defined in section 15, provides an effective barrier against the transmission of liquid water and can be applied to brickwork, stonework, blockwork or concrete substrates. 3.2 The product is satisfactory for use in the situations defined: for interior and exterior waterproofing of concrete, brickwork, stone and blockwork structures for waterproofing concrete floors, or as a waterproofing system eg for reservoirs and pools. 3.3 New buildings must be designed to withstand the hydrostatic pressure expected in service and the product should not be applied until structural movements due to curing has occurred. 3.4 The product is suitable for use in contact with potable water and has been approved by the Water Regulations Advisory Scheme for this purpose. 4 Practicability of installation The product is applied by suitably competent and experienced contractors using conventional techniques. Workmanship should comply with BS : Resistance to water penetration The product provides an effective barrier to the transmission of water. 6 Sulfate resistance 6.1 The product is based on cement and may be used in class DS1 soils or groundwater as defined in BRE Special Digest 1 : 2005 Concrete in aggressive ground, Part C Assessing the aggressive chemical environment (see Table 1). 6.2 Where the substrate has a high sulfate content, or is efflorescing, the advice of the Certificate holder should be sought.

4 Table 1 Concentrations of sulfates Design sulfate class 2:1 water/soil extract Groundwater Total potential for site (SO 4 g per litre) (SO 4 g per litre) (SO 4 %) DS1 < 1.2 < 0.4 < Condensation risk 7.1 If the product is applied to the inside of a basement wall, the wall structure will remain cold and wet, with subsequent risks of condensation and frost damage. 7.2 The condensation risk can be minimised by the application of a coat of proprietary lightweight cement-based renovating plaster, such as Sovereign Renderlite Renovating Plaster, and the provision of adequate heating and ventilation and/or the use of a dehumidifier. 8 Resistance to movement The product is unable to accommodate movement due to settlement and can only be used where settlement is not anticipated, or in conjunction with waterproof movement joints. The Certificate holder s advice on suitable materials should be sought. 9 Fixings 9.1 Special measures are necessary to avoid breaching the waterproof slurry when attaching fixings. The measures include: the use of Sovereign Pro-Stick 2000 to bond lightweight fixings to the coated surface recesses, made in the substrate to accept heavy-duty fittings, are coated with Hey Di K11 to form waterproof pockets. These are filled with an appropriate mortar and then coated with Hey Di K11 to provide continuity of the surface coating; and the use of floor standing supports. 9.2 If these techniques cannot be applied and it is necessary to breach the coating, the recess formed in the substrate must be filled with the product. 10 Resistance to damage 10.1 The coating is vulnerable to damage during installation, and in service, particularly in heavily trafficked areas where there is a risk of impact or abrasion Coatings of the product on external walls should be protected by boarding or a sand-cement render. 11 Maintenance As the product is protected by an overcoating layer or screed and has suitable durability, maintenance is not required. 12 Durability Under normal conditions of use, the product will provide an effective barrier to the transmission of groundwater for the life of the building to which it is applied. Installation 13 General 13.1 Hey Di K11 may be applied under most normal site conditions, but external application should not be attempted during rain nor at temperatures below 5 C Continuity should be maintained with any membrane (new or existing) in the basement floor using a flexible waterproof joint. 14 Surface preparation 14.1 Prior to application, all mortar joints must be flush-pointed, defects made good and irregular surfaces given a trowelled or floated finish with a sand-cement mortar mix (4:1) gauged with a Sovereign SBR Bonding Agent and water (1:4) All surfaces must be clean, sound, and free from existing coatings or contamination (eg paint, laitance, dirt, surface water) A new concrete surface should be bush-hammered, scabbled or grit-blasted to remove any laitance.

5 14.4 Water infiltration through the surface to be treated is either diverted by drainage or concentrated at weepholes and plugged with Hey Di Powder X (see section 15.9) If the surface shows frost damage, the affected area is removed and replaced before the product is applied. 15 Application 15.1 The prepared surface must be wetted with a gauging solution prepared by mixing one part Sovereign SBR Bonding Agent to nine parts water. This solution is applied to the surface 20 minutes prior to the application of the product A slurry is prepared by mixing (preferably by machine), approximately 25 kg of the grey product with 8 litres of the gauging solution (consisting of two parts Sovereign SBR Bonding Agent to one part water), in clean containers, until a plastic consistency is obtained. Care must be taken to prevent the formation of lumps The product is applied to the substrate in two coats using a block brush to achieve an overall application rate of 4 kgm The product should be used within 20 minutes from the time of mixing The first coat is brushed vigorously into the surface. A flowing edge should be maintained during the application. If this is not possible, when application is continued, the previously applied coat should be overlapped by at least 200 mm At all angled internal vertical and horizontal joints, a 25 mm angled fillet is formed from a thick paste of Hey Di Barrier Mortar mixed with clean water in accordance with the Certificate holder s instructions The second coat of the product is applied, using a block brush once the first coat and angled fillet have hardened sufficiently (after approximately four to five hours). If more than 24 hours elapse between coats, the first coat must be allowed to cure fully, before re-wetting and applying the second coat Each coat is examined and any damaged or areas of incomplete coverage recoated before the next coat is applied Once the final coating has fully hardened, the weeps should be stopped using Hey Di Powder X. Any recesses are coated with Hey Di K11, filled with an appropriate mortar and coated with Hey Di K11 to provide continuity of the surface coating. 16 Finishing 16.1 To protect the waterproofing from damage during service a bonding coat consisting of one part Sovereign SBR Bonding Agent mixed with one part water and 1.5 parts fresh Portland cement is applied. This is followed by a coat of a proprietary cement-based plaster such as Sovereign Renderlite Renovating Plaster or a suitable sand-cement mix. The plaster must be applied whilst the bonding coat is still tacky. If the bonding coat dries then a further application will be required. Gypsum-based plasters must not be used directly on the surface of the product Floors waterproofed with Hey Di K11 must be protected against traffic by the application of a suitable floorlevelling compound or sand-cement screed, the Certificate holder should be consulted on suitable materials. Technical Investigations 17 Investigations 17.1 An examination was made of independent tests conducted by Amtliche Materialprüfanstalt für Steine und Erden to determine: bulk density sieve analysis halogen content setting time stability of mix water retention of mix flexural strength compressive strength water vapour permeability modulus of elasticity shrinkage and swelling adhesion loss on ignition constancy of volume An examination was made of an independent test report conducted by Institut für Beton und Stahlbeton, Universität Karlsruhe, to determine the product s resistance to water pressure An examination was made of an independent test report conducted by Hygieneinstitut des Ruhrgebiets zu Gelsenkirchen, to determine the product s suitability for use in storage tanks for drinking water An independent report on the manufacturing process was examined, including methods adopted for quality control, and details were obtained of the quality and composition of the materials used A visit was made to a site in progress to assess the practicability of installation An assessment was made of the data contained in German Zulassung No Z issued by Institut für Bautechnik, Berlin, in the context of UK waterproofing and building regulations An assessment of the effect of the product on potable water was made under the Water Regulations Advisory Scheme.
