Restricted Access Bearing Piles

MEC Piling have an extensive fleet of rigs that can offer solutions in a wide variety of situations where confined spaces can be an issue. 

We have extensive experience in projects - particularly basement projects or residential extensions where access for our larger rigs might be an issue.

MEC Piling can offer the following Mini Piling solutions:-

Sectional Flight Auger Bored Piles – Open Auger Bore (Temporary Cased)

Open auger bored piles are constructed with sectional solid stemmed augers and temporary steel casing. Once the design depth has been reached the augers and casings are removed from the bore and the pile reinforcement is placed ready for concreting, once concrete has been introduced the pile is completed.

This method of piling requires bores to remain dry and stable for concreting, this is achieved by installed temporary casing through unstable or wet ground.

Sectional Flight Auger Bored Piles – Hollow Stem Bore (Concrete/Grout Injected)

Hollow stem bored piles are constructed with sectional hollow stemmed augers, once the design depth has been reached grout/concrete is pumped through the centre of the augers to base of the pile, the augers are then extracted whilst the grouting/concreting continues to ground level, reinforcement is introduced completing the pile.

This method of piling alleviates any issues with unstable bores and water strikes as the bore is permanent supported by the augers throughout construction.
