Piling

What is Piling and Mini Piling?

Piling and Mini Piling are forms of foundation stabilisation where piles are used to stabilise a structure. Piling solutions are ideal in the following situations:

  • When working in areas of limited access, such as house extensions or other domestic work.
  • When working in areas where noise and vibration are concerns.
  • When building on ‘made’ ground.
  • When working with weak/ soft ground conditions.

TAL Construction offer the following forms of Piling to civil & structural Engineers, contractors, developers and the public sector:

  • Underpinning
  • Augered Piles
  • Bottom-Driven Cased Piles
  • Drilled Dth Piles
  • Rotary Bored Piles
  • Self Drill Micro Piles

 

Piling and Mini Piling Techniques

 

Steps involved with a Continuous Flight Auger (CFA) Pile

Step 1: Set up with Lead Auger at the Pile position.

Step 2: Drill to desired depth adding segmental Augers as work progresses.

Step 3: Withdraw Augers while filling the borehole with grout through the hollow stemed Augers.

Step 4: Insert Reinforcement into wet grout.

Steps involved with a Bottom Driven Cased Pile

Step 1: Set up with lead casing on ground and drop hammer casing.

Step 2: Drop the hammer from a pre-determined height to drive the casing into the ground to a set depth adding casings as work proceeds.

Step 3: Withdraw the drop hammer.

Step 4: Fill the pile casing with concrete/ grout and place reinforcement.

Steps involved with a Rotary Bored (ODEX) Pile

Step 1: Set up with drill; with or without permanent casing at pile position.

Step 2: Drill to desired depth adding drill rods and casings as work proceeds.

Step 3: Remove drill rods leaving empty pile borehole.

Step 4: Fill pile borehole with concrete/grout and place reinforcement.

Steps involved with a Self Drill Micro Pile:

Step 1: Set up with drill bit at Pile position.

Step 2: Drill and inject grout simultaneously.

Step 3: Drill to desired depth using couplers to add extra lengths of threaded hollow bar as necessary.

Step 4: Secure anchor plate with two load bearing nuts and cast into concrete beam.
