Features & Benefits

• Uses:
  • Filling and bonding of cracked concrete where grout leakage may occur
  • Structural support where thin section grouting is required without the use of shuttering
• Rapid strength gain obtaining mechanical properties several times those of high quality concrete
• Non shrink enabling complete fill of the grouting area
• Resistant to most chemicals
• Stable to sea water & petroleum products
• Resists freeze thaw cycles
• Tested in accordance with the relevant parts of BS 6319

Preparation

• Ensure that grouting surfaces are free from dust and oily contamination
• Small gaps may be blown out using clean dry compressed air
• Steel should be free of rust and flaking mill scale
• All work surfaces must be essentially dry

Mixing

• Pour all of the hardener from the small bottle into the base container which has sufficient volume to act as the mixing vessel
• Thoroughly mix the two components until a homogenous thixotropic product is achieved
• Each pack will yield approximately 1 litre of mixed material

Placing

Supporting Structures

• The use of a shutter is recommended although the shutter need not be completely grout tight
• The Epoxy Thixotropic Injection Grout will “stay” once the placing pressure is released
• The shutter may be constructed from timber and sealed using Rapid Mortar or a suitable silicone sealant
• Apply a silicone based release agent to the formwork surfaces which will effect release after the grout has hardened
• Alternatively use thick polyethylene sheet

Crack Injection

• Drill and fix suitable injection tubes at approximately 300mm centres along the crack-line using Tecgrip CAS Cartridge for fixing the tubes and facing up the crack
• Allow prepared crack system to harden, approximately 6 hours at 20°C
• Use a Tecgrip Gun or a low pressure pump to inject mixed grout starting at the lowest point of the crack and work upwards to the highest point sealing off each injection point in turn
• Place the mixed grout within 25 minutes at 20°C. At the end of the useable time the mix will start to generate a great deal of heat. At this time any unused material should be mixed with sand to reduce the heat output and discarded
• Allow grout to cure for at least 24 hours
• Cut off external parts of injection tubes and make good with Polyester Putty
• Tools and equipment should be cleaned with Solvent prior to grout setting.
