Dewatering involves controlling groundwater by pumping, to locally lower groundwater levels in the vicinity of the excavation. The simplest form of dewatering is sump pumping, where groundwater is allowed to enter the excavation where it is then collected in a sump and pumped away by robust solids handling pumps. Sump pumping can be effective in many circumstances, but seepage into the excavation can create the risk of instability and other construction problems.

Why Choose Us?

WE REALLY LOVE WHAT WE DO & OUR WORK ON EVERY PROJECT TRULY REFLECTS THAT..

With years of experience and knowledge behind our team, BDECL Services are experts in the application of dual wall reverse circulation methods. In extreme drilling conditions of this technique, our experience will offer the maximum sample recovery achievable. Major advantages of this include:

  • Recovery of uncontaminated samples in high water bearing formation
  • Faster penetration than standard rotary or core drilling
  • Lower costs due to increased production
  • Reduced bit and mud consumable costs
  • No lost circulation even through fractures, voids and joints
  • No surface casing as the outer pipe supports the bore hole while circulation is maintained internally.
  • Straighter holes with flush joint pipe while drilling with RC.
