Rotary Percussive Drilling
Reinforcement Placement
Colloidal Pressure Grouting
Hydraulic Tensioning
Calibrated multi-strand jacks stress anchors beyond working load limits before wedge-locking into heavy structural bearing plates.
Down-the-hole hammer tooling advances through overburden and hard rock strata to verified refusal depth without destabilizing adjacent foundations.
High-tensile steel reinforcement cages or unbonded multi-strand prestressed tendons are lowered to design depths with centralizers intact.
High-pressure neat cementitious grout injection fills the borehole from the bottom up, displacing groundwater and bonding anchor zones.
Tensile Proof Load Testing
Every prestressed rock anchor undergoes cyclic hydraulic proof testing against basalt and granite bedrock to confirm design hold capacity before structural lock-off.
Real-time dial gauge deflection logs verify borehole bond strength, eliminating grout creep and securing deep basement diaphragm walls against lateral hydrostatic pressure.
