1.3 Typical Guaraflex R Tanking specifications, descriptions and uses are detailed in Figure 1.

Quality control1.4 Quality control checks are performed on incoming raw materials, during production and on the finished material.

2 Delivery and site handling2.1 Guaraflex PR is supplied in hot charge (molten) form, delivered to site in purpose-built transporters. The productinformation is supplied on the relevant delivery notes with each consignment. The manufacturer’s material safety datasheet should be consulted prior to discharging and handling the molten product.

2.2 Alternatively, the product may be supplied in block form (similar to traditional mastic asphalt) with labels bearingthe product type and name. Each block weighs approximately 16 kg and should be stored in the same manner astraditional mastic asphalt.

2.3 The bitumen primer is supplied in 5 litre and 25 litre drums. The product is classified under The Chemicals(Hazard Information and Packaging for Supply) Regulations 2002 (CHIP3) and bears the appropriate hazard warninglabel. The flashpoint and hazard classification are given in Table 1.

2.4 Guaraflash and Guarafelt membranes are supplied in rolls and should be stored on end on a clean, level surfaceaway from heat and protected from inclement weather.

Assessment and Technical Investigations

The following is a summary of the technical investigations carried out on the Guaraflex R Tanking System.

Design Considerations

3 Use3.1 Guaraflex R Tanking System is satisfactory for use as below ground waterproofing on substrates of; concrete,brickwork, blockwork or masonry constructions, or as a damp-proof membrane for solid floors (see Figure 1).

3.2 The membrane is compatible with the substrate listed in section 3.1 and is resistant to those chemicals likely tooccur in normal practice. If doubt arises on the compatibility with other materials, the advice of the manufacturer shouldbe sought.

4 Practicability of installationThe product can be installed readily by operatives experienced with this type of product.

5 Weathertightness5.1 Test data confirm that the system will adequately resist the passage of water and water vapour to the insideof the building and so enable a structure to comply with the relevant requirements of the national BuildingRegulations.

5.2 When used in the systems described, it will provide a weathertight layer capable of accepting minor structuralmovements without leakage.

6 Resistance to mechanical damage 6.1 Tests indicate that the system can accommodate, without damage, the thermal movement likely to occur in practiceand the limited foot traffic and light concentrated loads associated with installation and maintenance operations.

6.2 Reasonable care is required, however, to avoid prolonged loading by sharp objects, (see the TechnicalInvestigations section Table for Performance tests).

7 MaintenanceAs the product is confined within a structure and has suitable durability, maintenance is not required.

8 DurabilityGuaraflex R, when fully protected and subjected to normal service conditions, will provide an effectivebarrier to the transmission of liquid water and water vapour for the design life of the structure in which it isincorporated.

Installation

9.1 Surfaces must be dry, clean, and free from sharp projections and concrete nibs.

9.2 Guaraflex R Tanking System must be installed in accordance with the relevant requirements of CP 102 : 1973,Section 2, BS 8102 : 1990 and the manufacturer’s instructions.

9.3 Concrete substrates must be wood float or shutter finish and free from large voids and sharp projections such asconcrete nibs. Any abrupt irregularities greater than 3 mm must be removed or filled prior to application.

9.4 New concrete should be well compacted and finished, preferably by power floating and power trowelling,without excessive laitance, to a dense, smooth finish free from defects. Concrete toppings/screeds should be properlyformulated, applied and compacted. They should be bonded to the substrate and have a wood-floated finish withminimum laitance.

9.5 A minimum curing period of 28 days is normally allowed before installing the product on new concrete substrates.

9.6 Substrates should be free from physical defects such as cracks. Small surface defects can be filled with aproprietary mortar.

9.7 The surface must be dry, clean and free from loose particles, paint, grease and oil, or other contaminants whichmay affect the application of the product.

9.8 When application is made to an old substrate the advice of the Certificate holder must be sought.

9.9 Installation of the waterproofing layer should be carried out using the techniques for laying mastic asphaltdescribed in the relevant Clauses of BS 8218 : 1998. Where not controlled by hot charge delivery, advice on thelaying temperature should be obtained from the Certificate holder.

9.10 If required, Guaraflex PR waterproofing, can be applied over Guaraflex CP or Guaraflex CP Super felt isolatingmembranes.

9.11 Gauges should be used to ensure the correct thickness of Guaraflex PR and to provide a bonding edge betweenadjacent bays of asphalt.

9.12 The membrane should be protected against damage from construction activities as soon as possible afterapplication. The vertical membrane can be protected with a brick or block wall.

Pipe detailing [see Figure 1(7.b)]9.13 Pipes manufactured from coated or uncoated cast-iron mild steel or pitch fibre pipes are cleaned and brushedprior to painting with a primer coat. The primed pipe is sleeved with two coats of Guaraflex PR tanking.

9.14 The Guaraflex PR sleeve portion of the pipe to be built into the structure must project 75 mm before furtherGuaraflex PR is applied.

9.15 Guaraflex PR Tanking is then applied up to the Guaraflex PR sleeve which is warmed and cleaned to ensure asound joint. Additional coats are applied as a collar over the Guaraflex PR and pipe (clipped if necessary) andfinished with an application of a two-coat angle fillet.

9.16 A protecting wall is constructed if the tanking is external or a loading wall or slab if the tanking is internal.

10 RepairAny damage to the system must be repaired as soon as possible and before the application of the surface protection.The system may be repaired by removing the damaged area and reinstating the system to the original specification.The advice of the Certificate holder should be sought.

Technical Investigations

11 TestsThe BBA obtained samples of the Guaraflex PR asphaltic cement and Guaraflex PR for testing. The results of tests on theasphaltic cement and tests for the general physical properties and service performance on Guaraflex PR are given inTables 2, 3 and 4 respectively.

12 Investigations12.1 Factory visits were performed to examine the manufacturing and quality control procedures at the productionlocation.

12.2 A user survey was carried out to assess the product’s performance in service.

Additional Information The management systems of Guaranteed Asphalt Ltd have been assessed and registered as meeting the requirementsof BS EN ISO 9002 : 1994 by the British Standards Institution Quality Assurance, Certificate Nos KM 07942 andKM 07350.
