Parex Epoxy Injection Grout consists of a base component containing solvent free epoxide resin plus a low viscosity liquid hardener. Epoxy Injection Grout may be placed by free flow under gravity or may be injected using a suitable hand or mechanical pump. Grouting of gap dimensions 0.1mm to 10mm may be easily achieved.
- Rapid strength gain obtaining mechanical properties several times those of high quality concrete
- Non shrink enabling complete fill of the grouting area
Please note: 6.075kg size is also available - please contact our Technical Department for availability on 0113 2455450 (option 2) or send a message to [email protected]

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
