Features & Benefits

• Uses include:
  • Crack Injection Applications
  • Filling and bonding of cracked concrete
  • Structural support where thin section grouting is required
  • Structural support where dynamic load resistance is required
  • Bonding of lifted floor toppings
• 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 and 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
• For each pack size all containers must be used to complete the mix
• Pour all of the resin and hardener into a suitable mixing vessel
• Thoroughly mix the components until a homogenous clear product is achieved
• Each 1.13kg pack will yield approximately 1 litre of mixed grout
• Each 6.075kg pack will yield approximately 5.62 litres of mixed grout

Application

Pouring Under Gravity

• For supporting structures, where Epoxy Injection Grout is being poured under gravity, the use of a grout-tight shutter is essential. This 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 affect 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 Polyester Mortar/Putty for fixing the tubes and facing up the crack
• Allow prepared crack system to harden, approximately 6 hours at 20°C
• Use 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 @ 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 Mortar/Putty
• Tools and equipment should be cleaned with Solvent prior to grout setting
• No special curing practice is required
