CONTENTS CONCRETE REPAIR CORROSION CONTROL GROUTS & ANCHORS PROTECTIVE COATINGS INDUSTRIAL FLOORING SURFACE TREATMENTS JOINT SEALANTS CONCRETE JOINTING JOINT FILLERS WATERPROOFING WATERSTOPS ROOFING TIMBER FLOORING ALPHABETICAL INDEX 431 Application Instructions Do not remove waterproof wrapping from Hydrocor until immediately prior to fixing. Hydrocor must be fixed against one section of concrete after shutter removal. It may be fixed in place by copper nails or by bonding to concrete using Fosroc Construction Adhesive . The next section of concrete is then poured in place with minimal delays, directly against the Hydrocor. After initial cure of the concrete, the top section of the Hydrocor is removed by power brush, grinder or saw to form a sealing slot of the required dimensions. To avoid the cutting or grinding step, Hydrocor may be initially placed below concrete surface (at depth of required sealing slot) then another section of Hydrocor, timber or polystyrene foam placed above the fixed Hydrocor, reachingto the concrete surface. This unattached top section of filler is easily removed once concrete has cured. Note: a bond breaker such as polyethylene tape must be applied over the Hydrocor prior to application of the joint sealant. See individual Technical Data Sheets for details. Limitations Hydrocor may cause staining of the surrounding concrete in damp conditions, especially light coloured concrete or where exposed aggregate finishes are produced by high pressure hosing. Staining usually disappears after 6-8 weeks normal weathering. Stiffjoint, a non staining polyethelene foam filler may be more suitable in such applications.
