Steel Hollowbar SDA
The HDDR Hollowbar Self Drilling Anchor (SDA) serves as an economical solution for soil nails, tie backs, and micropiles when traditional casing method is not feasible. Using a sacrificial drill bit, the SDA system is capable of drilling a hole while injecting grout at a high pressure, forming a grout column. The system can then be post tensioned to provide needed ground support.
The self drilling anchor system consists of:
- Anchor Bar
- Bearing Plate
