Our branded DPC injection cream for the treatment of rising damp is accredited by the BBA. Certificate issue number: 16/5313. It offers 25% active ingredient which is higher than most brands in the market place. DryFix DPC damp proofing injection cream is a Silane based chemical cream that is easy to apply without the need for specialist equipment. The Silane cream works by migrating through the mortar bed once injected through a series of pre-drilled holes. Moisture within the mortar triggers the resin carried within the cream to create a pore liner within the mortar. Once fully cured, a new, fully formed damp proof course becomes effective. DryFix DPC damp proofing injection cream is suitable for specialist damp proofers and general trades. A 20 year performance certificate is available on request. The patented installation method has been optimised to ensure that it is effective on a wide range of mortar types, including porous and low-alkalinity mortars as well as stone and rubble filled walls. For best results, this product should be applied in accordance with the British Standard 'Code of Practice for Installation of Chemical Damp Proof Courses' BS 6576 (2005). Contaminated plaster should be removed and the walls re-plastered to an appropriate re-plastering specification. BENEFITS Easy to install, no specialist equipment required Virtually odourless Non-hazardous to the environment Ready to use Fully cured within 2 – 6 weeks In all cases, a remedial chemical damp proof course should, as far as is possible, be installed in accordance with the British Standard ‘Code of Practice for Installation of Chemical Damp Proof Courses’ BS 6576 (2005). In particular, the inserted DPC should be below the level of timber floors. Contaminated plaster should be replaced in accordance with BS6576 (2005). New plaster should not bridge the DPC. Injecting DryFix DPC in Suspended Timber Floor Where a suspended timber floor is supported on joists and/or a wall plate bearing on, or embedded in, the wall, there is a possibility of decay, particularly where concealed timbers are in contact with the damp wall. The condition of these timbers should be ascertained and remedial action taken if necessary. Preparation The course to be injected is chosen so that the position of the horizontal DPC complies, as far as is practicable, with the recommendations of BS 6576 : 2005, clause 8.3. Internal walls on solid floors are treated as close to the floor as possible. Complementary vertical DPC’s are positioned, where necessary, to isolate treated walls from the effects of rising damp in adjoining walls or to maintain continuity between horizontal DPC’s at different levels. Internal skirting and flooring are removed, as necessary, to expose the area for treatment. Externally, the proposed DPC line is exposed, where necessary, by removing any facing material. Internal plastering which may be affected by hygroscopic salts is removed from the area to be treated to a height of at least 300 mm above the maximum level of the rising damp (subject to a 1 m minimum height). Procedure Holes 12 mm in diameter are drilled horizontally at the base of perpends and at maximum intervals of 120 mm along the selected mortar course. Solid walls of brick or stone should be drilled from one side to within 20 mm of the opposite face. Where this is not possible advice should be sought from the Certificate holder. For preference, cavity walls should be treated from both sides but, if the thickness of the individual leaves permits, may be treated from one side. When undertaking treatment from one side, the drill must pass completely through the selected mortar course, then across the cavity and to a depth of 90 mm in the other leaf. The cavity must be clear before treatment. When treating cavity walls from one side it is essential that the holes in each leaf are filled. In random stone and rubble infill walls, the mortar course should, if possible, be followed at the appropriate selected level, or drilling's may be made into porous stone. Where the variable thickness of stone walls and the possibility of rubble infill dropping and blocking injection holes cause difficulties, it may be necessary to drill to 50% of the wall thickness from both sides at a corresponding height.The injection process consists of loading the DryFix cartridge into the applicator gun and inserting the gun delivery tube into the full depth of the predrilled hole. Each hole is backfilled fully with DryFix to within 10 mm of the surface by slowly squeezing the gun trigger whilst withdrawing the delivery tube.Particular care must be taken to avoid bridging the dpc, either internally or externally. Where external rendering has been removed, it must be restored, ending in a bell casting above the injected dpc. Holes in the external wall surfaces are plugged with sand/cement mortar. The treated walls are left for at least 14 days to allow initial drying out. Internal plastering is applied in accordance with a BBA-approved replastering specification.
