Parex Epoxy Thixotropic Injection Grout

Epoxy Thixotropic Injection Grout is a Thixotropic Two-Part Epoxy Resin System

Parex Epoxy Thixotropic Injection Grout is a thixotropic two-part epoxy resin system. The base resin component is thixotropic, with a low viscosity liquid hardener. Parex Epoxy Thixotropic Injection Grout may be placed using suitable mortar gun, or injected using a suitable hand or mechanical pump. Grouting of gap dimensions of 0.1mm to 10mm may be achieved without the use of grout tight shuttering. The two-part system gives rapid strength gain obtaining mechanical properties several times those of high quality concrete. The Product is non-shrink, enabling complete fill of the grouting area. The hardened grout is resistant to most chemicals, stable to sea water, petroleum products and resists freeze thaw cycles.

  • Thixotropic.
  • Can be placed without the need for grout tight shuttering. 
  • High mechanical strength.
  • Good adhesion to most construction materials (i.e. concrete, masonry, stone, steel, wood, etc.).
  • Easy to use.
  • Can be placed with a suitable hand or mechanical pump.
  • Suitable for grouting and sealing the narrowest of gaps (as thin as 0.1mm).
  • Can be used to fill cracks, fissures and voids up to 10mm.
  • Non-shrink.
  • Application temperature range +5°C to +30°C.
  • High early strength gain.
  • Hardened grout is resistant to most chemicals, sea water and petroleum products.
  • Can provide structural support where dynamic load resistance is required.
  • Can be used to fill and bond cracked concrete.
  • Hardened grout resists freeze-thaw cycles.
  • Solvent free.
  • Available in a convenient 1.191kg size.

Yield

Application steps

SUBSTRATE 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, approximately 2-3 minutes.

APPLICATION

The use of a shutter is recommended although the shutter need not be completely grout tight.

The Parex Epoxy Thixotropic Injection Grout will 'stay' once the placing pressure is released.

The shutter may be constructed from timber and sealed using a rapid mortar (e.g. Parex Rapid Mortar Light) or a suitable silicone sealant.

Apply a silicone based release agent to the formwork surfaces which will enable 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 for fixing the tubes and facing up the crack (Sikadur-31+ is a suitable product for this purpose). 

Allow prepared crack system to harden, approximately 6 hours at 20°C.

Use a low pressure pump to inject the 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 the useable time as given in the Application time section.

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 a suitable product (like Parex Epoxy Putty LS or Sikadur-31+). 

CURING TREATMENT

No special curing practice is required.

CLEANING OF EQUIPMENT

Clean all tools and application equipment using the Sika® Thinner C in accordance with the Product Data Sheet. Hardened material can only be mechanically removed.
