Design & Install Piles and Foundations

Reduce costs by having

One Contractor to Design and Install Piles & Foundations

Advanced Mini Piling Systems provide the full package of design, pile and foundation systems across the South West in Frome BA11, Warminster BA12, Westbury BA13, Wiltshire, and Somerset. Reinforced steel beams are used to connect all the piles together, transferring the load of the superstructure onto the piles.

With the help of void products, the R/C Beam, Slab, and Raft are isolated from existing ground movements such as heave, which is caused by weather conditions, tree roots, and water leaks.

These can come from mains water, rainwater and wastewater. The void material collapses over time, and with the aid of anti-heave sleeving, which can be cardboard with a special slip coating or a grease-lined plastic sleeve, the stress on the pile is greatly reduced by allowing the heaving ground to move naturally, not impacting on the foundations.

Piled Beam Systems, Covering London and the Southern United Kingdom.

Piled Beam Systems are used in all commercial and residential developments. They are a requirement by building authorities, where clays and soft ground conditions are present.

Piled Beam Systems also reduce the need for traditional deep footings, which reduces the cost of material being removed from the site, and the cost of large amounts of concrete to fill the deep excavations. This saves money and reduces the impact on the environment, and transport.

Trench sheets are products that retain the sides of the excavation, prevent any collapse of material into steel reinforcement in poor ground conditions, and prevent grout loss from concrete.

Claymaster is placed around all internal sides of the piled beam, and prevents expansion of the fill material, increasing lateral loads on the piles and beam system.

This capping beam works on the same principle as a piled beam but has piles placed directly to one another forming a wall. This is used for lateral and vertical loadings.

Piled Rafts & Slab Systems

Piled Rafts and Slab Systems, Covering London and the Southern United Kingdom.

Piled Rafts and Slabs are used where a whole building needs support. In commercial developments, the Piled Slab acts as the floor and supports walls.

Piled Rafts and Slabs are well suited to new build domestic projects, where timber frames and modular systems can be erected directly off the reinforced concrete slab, after adequate curing time has been allowed. All Piled Raft and Slab Systems are compatible with void-forming technology.

Piled Slabs and Rafts can be installed in existing subsiding properties. However, unless the building can be underpinned from the outside with cantilever beams or traditional underpinning, the lower ground floor or basement must be excavated.

Once the piles are installed, steel reinforcement is laced throughout the building with needles pocketed into the external walls, spreading the load of the building over the piles. With the void under the slab and external footing removed below the newly installed slab, the building is in total isolation.

Cantilever Beams and Underpinning, Covering London and the Southern United Kingdom.

Cantilever Beams are used to stabilise buildings with subsidence, by installing a pair of Piles approximately at 1 to 1.5 m intervals the length of the external walls. The pair of piles consists of a compression pile, which is closest to the wall and maintains its proximity to the building.

As the compression pile has the loading of the wall placed onto it via the needle beam, the needle beam is inserted into a pre-cut hole in the wall. These can either be made up of steel reinforcement or an H section.

The second Pile installed approximately 1 m out from the compression pile, works in tension and holds the rear of the beam down supporting the wall. This cantilever action gives this system its name.

Piled underpinning is a method undertaken when the building cannot be needled into. This is because either it’s structurally unsound or it is on a failed R/C ring beam, piles installed, and the beam is excavated below the footing. This requires deep excavation in some situations.

Piled Pads and Pile Caps

Piled pads consist of one or more piles working together in compression to support a column. These piles are used in commercial developments, mezzanine floors, modular builds for hospitals and schools and residential developments for glazed extensions, garden rooms and orangeries.

We work across Wiltshire and Somerset including Frome BA11, Warminster BA12, and Westbury BA13. If you would like more advice and guidance about piled foundations, get in touch with us here at Mini Piling systems. As well as piled foundations, we also specialise in basement construction & piled retaining wallsdriven piling, and screw piles.
