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.
