Piling Mat design

In all piling projects the stability of the plant is key and as such, a suitably designed piling mat is essential if the works are to be executed in a safe and controlled manner. It is particularly important that the working platform does not deteriorate or suffer from any movement and/or heave because in piling work the specialist equipment used has a high centre of gravity and the consequences of a collapse can be fatal.

The traditional method of constructing a piling mat is to import and lay a deep layer of stone. Reductions in stone depth have been mitigated by adding plastic containment grids at the base of the structure to spread loadings and limit shear.

This is an unsustainable method of construction adding numerous unnecessary lorry movements of materials to and from the site. Whilst a graded stone mat with a well-designed geogrid giving under support and containment has been proven to meet safety requirements. It is a compromise as the loose stone in the mat can cause deflection and require longer setup. In addition piles have been known to snag going through the plastic geogrid base layer an unnecessary safety issue.

PowerCem for ten years have been offering onsite stabilisation of in-situ materials to meet all UK piling mat standards. We can achieve loading specifications to meet the requirements of the heaviest of rigs constructed from any soil/ground type.

The stabilisation process off the bound soil mat will be carried out with either Wirtgen self-drive or Stehr tractor pulled dust free soil mixers.

The high modulus of elasticity of RoadCem bound soil mats has a dampening effect which will make driven piling operations, safer and far quicker with easy setup and zero deflection.

The ductile mat will eliminate breakaway, and cracking around the piles will also be reduced, allowing ongoing use of the bound soil mat as a cost-effective foundation element.

We believe that we can save time, cost, and embodied carbon for most piling mat requirements: Driven, Auger and Sheet.

Strength testing can allow early commencement of piling operations and all plant operational certifications can be arranged by our partner team engineers, as part of the installation package.

The wrapping cage like bond created by our patented zeolite technology allows weak, organic, and even sulphate bearing soils to bound together to form impermeable heave resistant monolith layers that will have a flexural easy to work nature allowing easier pile penetration with very little deformation during the lifetime of the mat.
