Applications include plugging in-situ and precast concrete segments in tunnels, water storage tanks, sewerage mains and processing tanks, basements, below ground car parks, access chambers, building foundations and mines. Vandex plug is effective in sealing water leaks through concrete, concrete block walls, brickwork, earthenware and all types of stone and masonry. Advantages „ Highly abrasion resistant „ Stops water flow „ Sets in approximately 30 seconds after mixing „ Permanent durable repair „ Works on concrete, brick, stone and all types of masonry „ Can be installed underwater „ Non-toxic „Can be mixed with water or used as a dry powder „ Easy application „ Colour compatible with the host concrete „ Packed in convenient resealable plastic containers Description Vandex Plug is a one-component, rapid setting, ready-mixed, cementitious, waterproof plugging mortar which is ready for on-site application to leaking cracks and water seepage areas in concrete, stone and all types of masonry after mixing with water. Test Reports and Approvals WRc Evaluation & Testing Centre Ltd, Oakdale, Gwent ‡ Potable water compatibility WBS Approval / Water Byelaws Scheme - approved Drinking Water Inspectorate, Romney House, London ‡ Potable water compatibility - DWI-approval National Sanitation Foundation, Michigan ‡ Potable water compatibility NSF-approval Design Criteria Vandex Plug can be applied in vertical, horizontal and overhead applications. Areas of leakage must be identified and a rebate with width and depth of 30-50 mm, formed along the defect to accept the Vandex Plug. Applications where a very high water pressure exists behind the leak can be repaired more effectively by drilling a hole through the substrate and inserting a plastic tube to allow the water to flow and release the pressure. Plugging can then be performed on the surrounding leakage points before removing the plastic tube and plugging the hole. Properties Form: Cementitious powder Colour: Cement grey Bulk density: 1.10 - 1.30 kg / L Initial setting time: 30 seconds (after mixing) Physical or chemical Chemical cure change: Application temperature: 5 - 30°C Chemical Resistance Vandex Plug is suitable for use in contact with sewerage water, sea water, aggressive ground water and a range of chemical solutions. Maintenance No special requirements, any damage identified during normal inspections should be water blasted clean, chiselled out, repaired and recoated as appropriate. Specification Clauses Where so designated, surfaces subject to water leakage must have the leakage points identified and repaired using a one-component, rapid setting, cementitious plugging mortar. All cracks and leakage points will be chiselled out to create a rebate having a minimum width and depth of 25 mm. The plugging compound must have a bulk density of 1.1 to 1.3 kg / L and a setting time of 20 - 40 seconds after mixing with clean fresh water. The cementitious mortar must be non-toxic and be suitable for hand or trowel application to vertical, horizontal and overhead repairs. March 2008
