Features
-
High-strength fully threaded bars come in easy to handle 10' (3 m) lengths
- Standard ISO rope thread (R32-R51) or trapezoidal thread (RR64-RR108) promotes increased bond between bar and grout
- A wide selection of drill bits are available for various ground conditions
- Matching couplers, hex nuts, and anchor plates available for all bar sizes
- Continuously threaded bars for cutting and joining at any length
- Enhanced corrosion protection with hot-dip galvanizing available upon request
- Grout swivels available for most drill-rig configurations
Advantages
- Simple one-step installation
- Increased production through simultaneous drilling and grouting
- Allows tremie grouting, helping eliminate grout voids
- Can be installed in loose or collapsing soils without the need for a temporary casing to support the borehole
- Allows the use of smaller and less expensive drill rigs
- Can be installed in low overhead areas and sites with limited access
- Improves density of surrounding soils
- Promotes higher skin friction and soil bond due to rough pressure grouted borehole
- Fully threaded throughout the entire length to allow the bars to be cut at any desired length
- Additional corrosion protection can be provided
- Grout swivels can be used to retrofit standard rotary percussion drills
