BDC Drill Grout
BDC Drill Grout
BDC Drill Grout – special drilling mud used in horizontal drilling projects with special self-hardening properties. Drilling works using microtunneling and HDD techniques, where geological structure includes loose formations that can lead to serious drilling complications and failures. Thanks to the BDC Drill Grout, we achieve drilling hole stabilization and ensure uniform and thorough filling of the inter-ring space. The product is ideally suited to overcome obstacles such as railroad tracks, roads and low-load land.
The use of BDC Drill Grout as an addition to drilling mud provides following advantages:
- Stabilizes walls of the borehole
- Minimizes subsidence of the ground
- Helps with the installation of pipes in the borehole
- Appropriate rheology of the suspension
- Filling empty spaces and stabilizing the opening wall
- Protection against groundwater inflow
