Chemical grouting for foundation bolts is a method used to fix anchor / foundation bolts into concrete, stone, or masonry using a high-strength chemical adhesive instead of conventional cement grout. It is commonly used where high load capacity, fast installation, or retrofit fixing is required. LG Industries manufactures foundation bolt.
What is Chemical Grouting?
Chemical grouting involves injecting a resin-based adhesive (epoxy, polyester, or vinyl ester) into a drilled hole, then inserting a threaded foundation bolt. Once cured, the chemical forms a strong bond between the bolt and base material.
Types of Chemicals Used
Epoxy Resin (Heavy Duty)
Very high strength
Long curing time
Suitable for heavy machinery & structural loads
Vinyl Ester Resin
High load capacity
Faster curing than epoxy
Good chemical resistance
Polyester Resin
Medium load applications
Fast setting
Cost-effective
Chemical Grouting Installation Process
Drill hole to specified diameter and depth
Clean hole (air blower + brush)
Inject chemical grout into the hole
Insert foundation bolt / threaded rod with slow twisting
Allow curing time (as per chemical manufacturer)
Fix base plate using nut & washer after curing
Suitable Foundation Bolts
Threaded rods (MS / HT / SS)
Stud bolts
Rebar anchors
Anchor bolts for retrofitting
Chemical anchor foundation bolts
