Features & Benefits

• Uses:
  • Sealing pipe-work which passes through concrete
  • Sealing spacers in formwork
  • Sealing cold joints in reinforced concrete structures
  • Sealing where water seeps through cracks in reinforced concrete structures
  • Bonding various types of joints
  • Sealing lights and drainage outlets in swimming pools and tanks
  • Sealing construction joints in concrete walls
• Single component hydrophilic paste, used in repair and waterproofing operations
• May be applied on uneven surfaces
• May be used at any temperature and with any kind of water which infiltrates or seeps through
• On contact with water, its volume increases and, if well confined, is resistant to considerable hydrostatic pressure
• Bonds perfectly to slightly damp surfaces, as long as they are clean and solid

Application

• Eliminate all dust and loose parts from the surface, and any other material which could compromise the bond of Mapeproof Swell
• The substrate may be damp, but there must be no water on the surface
• The size of the bead of Mapeproof Swell which is extruded may be adjusted by cutting the tip on the nozzle according to the diameter required. The normal size of the bead is from 6 to 13 mm. Cut the tip at the first line to obtain this size
• With a single cartridge, approximately 3 metres of bead with a diameter of from 6 to 13 mm may be formed
• Apply the bead of Mapeproof Swell continuously and evenly
• Mapeproof Swell expands in all three directions, in the direction of the lowest resistance. Therefore, to make sure that Mapeproof Swell functions correctly, it must be enclosed or injected into a crack or a joint. This product is not suitable for surface only application, and must always be confined
• Before pouring on the concrete, wait until the product has completely set
• If Mapeproof Swell is applied on steel pipe-work, remove all traces of oil and grease used to lubricate the joints using ethanol
• If cracked concrete requires sealing, break out the sides of the cracks or construction joint using suitable mechanical means, to a depth of at least 6 cm. After removing all dust and rubble, apply Mapeproof Swell and then limit its boundaries using a suitable product from the Mapegrout line
• If water is seeping through, block the flow using Lamposilex and then apply Mapeproof Swell on both sides, making sure that the boundary formed is at least 5 cm
• Mapeproof Swell is available in cartridges containing 320 ml of the product. To apply Mapeproof Swell, cut off the tip of the nozzle according to the size of bead required, and pierce the membrane under the nozzle. Insert the cartridge in an extrusion gun and apply the product directly onto the concrete or element to be sealed
• Do not apply Mapeproof Swell if the surface on which it is to be applied is highly contaminated with acid or solvents. Carefully clean the surface before application
• Do not use Mapeproof Swell on dirty or weak surfaces
