A rapid-setting water-stop repair compound

Feb Febtank Plug, when mixed with clean water, provides a ready-to-use ultra-rapid setting durable plugging compound for active water leaks in concrete and masonry. The material expands as it cures to form a watertight seal with similar characteristics to concrete. Use on holes, joints and cracks. Sets both above and below the water level.

  • Ultra-rapid set, instant plugging of leaks.
  • Requires the addition of water only.
  • Expands as it sets, ensuring a permanent watertight seal.
  • Similar characteristics to, and compatible with, concrete.
  • Chloride-free.
  • Does not promote corrosion of the reinforcement.
Usage
Feb Febtank Plug is used to stop active water or seepage under pressure through joints, cracks and holes in concrete or masonry, where a normal mortar would be washed away and resin mortars would not bond. Areas of use include:
  • As a seal for construction joints or floor joints prior to basement tanking with FEBTANK SUPER.
  • For instant sewer connections.
  • For sealing cracks and construction joints in reservoirs and other water retaining structures.
  • For rapid anchoring of bolts, conduits, pipes, railings, sanitary equipment, etc.
  • Joint filling, pointing between concrete segments in concrete and brick tunnels, sewage systems, pipes and mines.
