Restricted Access Piling

Sectional Flight Auger Bored Piles – Open Bore

This type of pile constructed with sectional solid stemmed augers, once the design depth has been reached the augers 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.

Sectional Flight Auger Bored Piles – Hollow Stem Bore

Sectional Flight Auger Bored Piles

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

For both systems we offer diameters ranging from 300mm – 450mm and up to depths of 20.0m.

Steel Cased Bottom Driven Piles

Steel Cased Bottom Driven Piles

Steel cased bottom driven piles are formed using a circular steel casing with a crimped (pointed) toe. These casings are driven into the ground using an integral weight which is repeatedly dropped a pre-determined distance. The energy is transferred from the weight through a dry mix concrete plug in the base of the pile, and into the outer steel casing which propels the casing through the surrounding soil. The Casings are connected together by forming a continuous water tight fillet weld around sections. Once the pile length has been achieved the weight is withdrawn, and the pile is completed by filling the casing with concrete and reinforcement.

Steel Cased Grundomat Driven Piles

Grundomat Driven Piles

Grundomat driven piles are formed using a circular steel casing with a crimped (pointed) toe. These casings are driven into the ground using a pneumatic pile hammer which is placed inside the casing. Once the hammer is activated the energy is transferred through a dry mix concrete plug in the base of the pile, and into the outer steel casing which propels the casing through the surrounding soil. The Casings are connected together by forming a continuous water tight fillet weld around sections. Once the pile length has been achieved the grundomat is withdrawn, and the pile is completed by filling the casing with concrete and reinforcement.
