Pile base grouting is a contemporary means of strengthening the soil beneath a pile foundation by injecting a mix of cement, chemicals, and water at high force. This process is powerful in Nearly doubling the load ability of a pile foundation. Pile base grouting is a sophisticated technology introduced and developed by Freehold Construction and Development (FCD) in Bangladesh, and it's been successfully utilized in numerous pile foundation tasks in Bangladesh. This technological innovation was also useful for the Padma Bridge’s pile foundation, under the direction of foreign consultants, to boost the load capability on the piles. The perform was carried out through the Chinese contractor Sinohydro Company Restricted.

The method is almost solely employed for halting huge inflows (commonly better than one,000 gpm), although may be Utilized in apps where its elasticity inside the cured condition is attractive. Bituminous grouting is mostly made use of exactly where void dimensions or Pile Foundation Contractors BD water circulation is just too terrific to permit other grouting methods to perform as a consequence of grout washout. The benefit of bituminous grout is usually that as the new bitumen is pumped into the bottom, finally, a leading edge of cured, elastic bitumen sorts.
The precast concrete pile is cast in pile bed within the horizontal type If they're rectangular in shape. Generally, circular piles are Solid in vertical kinds.
