Product Catalog

The patented MPA bolt improves the normally stiff R32 self-drilling bolt by providing a smooth section of bar. The smooth bar is then annealed to improve ductility for demanding dynamic conditions. 

Fast, single-step anchoring system using standard equipment. Efficient installation since drilling and grouting can be performed in a single operation, saving both time and money.

• The MPA Bolt is a high dynamic capacity hollow “self drilling bolt” for squeezing, dynamic, and quasi-static broken ground conditions
• The hollow bolt design with sacrificial anchoring drill bit allows in cycle rapid development or post grouting making it ideal for broken ground and speeding up rehabilitation jobs
• Smooth annealed sections allow for deformation and energy absorption of up to 40kJ with independent test reports available Range of drill bits available
• Compatible with cementitious and pumpable resin systems.
• Dynamic test results available with J-Lok P pumpable resin system
• Galvanized and PE corrosion protection coatings available

The MPA Bolt System is specially designed for use with J-LOK P™ Pumpable resin, eliminating the capsule and injecting directly into the hollow-core bolt.
