TOP DRIVEN PILE ADVANTAGES > Capacities are calculated using long established pile-driving formulae. This helps eliminate the risk of an inferior pile resulting from ground conditions that vary from those perceived from boreholes.
> There is an infinitely adjustable hammer driving force available, with an accurate and consistent hammer energy.
> Hammer efficiencies in the high 90s, low losses and low vibration.( Use of a heavy hammer with a low terminal velocity results in an ideal piling environment.)
> There are no unforeseen pile capacity reductions due to hammer energy losses from hammer striking the walls of deflected piles.
> Piles are cured before arrival on site and can be dynamically (CASE) tested to twice their Safe Working Load (SWL) immediately on completion, rather than having to wait days until the concrete is cured as is the case with bored piles.
> The system and rig are suitable for simulated static tests (CAPWAP).
> Continuous computer monitoring of driving resistance is also possible.
> There is no possibility of inclusions or cavities in the concrete as a result of the controlled environment they are created in.
> Ground water leakage does not affect the concrete in the pile.
> Pile stiffness keeps the pile straighter.
> Square end deal well with obstructions.
> It is a dry process, so there is no wet concrete on site.
> Rock shoes are available on request.
> For mini piling, use of a relatively big hammer results in fast driving rates.
AND MOST IMPORTANTLY:
> Comfort factor! There is no substitute for seeing a hammer bounce on a completed pile and knowing that it has reached its capacity.
ADVANTAGES OF OUR RIGS OVER CONVENTIONAL PILING MACHINES
> Our equipment is 1/2 to 1/3 the size and weight of many conventional rigs and so:
> They need less room for access.
> They do less damage on entering the site.
> They work in lower headroom.
> They need less site preparation. Normal preparation for our 17 tonne lorry mounted rig is the same as that needed by a loaded premix lorry.
> Our 14 tonne track machine is for confined and soft sites where we normally only ask for 12 inches blinding on fabric.
> Our patent low vibration hydraulic hammers allow us to work inside historic buildings.
> Our 3 tonne mini rig can pass through a 1m wide opening, or be lifted over houses on a crane and can work up very close to existing buildings for conservatories and extensions.
