Procedure
- Fix the embedment depth and hole size with Armstrong or the design engineer.
- Drill to depth, blow out the dust with compressed air and brush the hole clean.
- Clean the bolt or bar of oil, loose rust and scale.
- Mix the two parts of RAPIDSTRONG AG fully; mix only what can be placed in its pot life.
- Pour the measured quantity into the hole and press the bolt to the bottom so the resin fills the annular gap.
- Hold the bolt still until the grout has set, and load only after it has cured.
Important Suggestions
Resin bonds to dust, not concrete, if the hole is not cleaned. Bolts in cast pockets are grouted with non-shrink grout instead.
Why This Treatment?
A polyester resin anchor grout bonds steel to concrete with high pull-out strength and fast cure, without the expansion stresses of mechanical anchors.
