Limited Access & Mini Piling – Is space a problem?
Often we are asked if a restricted working space will be an issue. Our equipment range is versatile & we can undertake piling projects in both large construction sites & houses with limited working space. We provide a range of Piling Services for a number of properties.
Our kitten rigs are built to be small but highly effective & can access spaces as small as a doorway. They are the perfect solution for domestic properties with low headroom or restricted access areas. The hydraulic widening track enables us to position it into the most compact spaces. Once the machine is in place, we’ll widen the tracks to form its operating position.
Silent Electric Piling- Is noise a concern?
Our environmentally-friendly electric piling rig dramatically reduces noise & emission pollution. This is a perfect solution for built-up areas such as London.
Open Bore Piling
Open bore piling is ideal for cohesive ground conditions such as clay. It can be used for both small & large-scale projects & causes minimal vibration.
The auger is drilled down to depth and when removed it pulls out the soil with it. This process will be continually done until the desired depth is achieved. Reinforcement is then placed, and the pile is filled with concrete.
(CFA) Continuous Flight Augering Piling
CFA piling is the ideal method for unstable & soft ground conditions. It is also one of the quietest piling techniques that are both fast and economical. Its limited noise and vibration emission make it ideal for urban areas. We also have a range of auger sizes that enables the most cost-effective design.
Once the augers are drilled into the ground to their required depth, concrete is pumped through the hollow stem of the auger, as the auger is removed from the hole, the reinforcement is then inserted.
Sections of interlocking steel sheet piles are driven into the ground, providing soil retention & excavation support. It can be used as a temporary or permanent wall within construction.
The hydraulics push the sheet piles into the ground by gripping onto previously installed piles. In environments where the ground is hard or full of rubble and gravel, using this method may require us to also use a high-pressure water jetting system to help the machine push the pile into the ground.
Ground Beams are usually constructed from concrete & are generally quick to install compared to methods such as conventional footings.
Trenches are excavated to the required width & depth & reinforcement is inserted & tied to the pile reinforcement. The beam is then concreted creating a foundation for blockwork.
Reinforced Concrete Slabs
Reinforced concrete slabs are a common structural element in modern buildings & are most commonly used to construct structural floor slab and foundations.
Layers of reinforcement are placed on to the piles & formwork is constructed. Concrete is then poured & levelled providing an even base to build on.
Contiguous Bored Pile Walls
Contiguous pile walls are sequential cast-in-situ piles & are generally used in basement construction. The pile wall provides excavation support & it is tied into the basement reinforced concrete construction.
They are often used to construct economic & efficient retaining walls. They are perfect for underground structures where working space may be limited but the structure needs support. They minimise bulk excavation, whilst also helping control the external environment.
Secant Bored Pile Walls
One pile is cast using a lower strength concrete & the other is drilled in between the primary piles, creating a retaining wall. The walls may need reinforced concrete lining for permanent use in sandy ground conditions. Like contiguous pile walls, the secant method is generally used in basement construction.
King Post walls are easy to install & are also a cost-effective technique. They are ideal for garden retaining walls.
Similar to cast-in-situ piles, the method is dependent on ground conditions. Once the concrete is inserted, a steel column is placed instead of reinforcement cages. Timber or concrete provides infill between the King Posts.
Design & Calculation
Our design team is led by Dr A. Adekunte. He is highly skilled, has a PhD in Geomechanics & also lectures about innovative pile techniques across the world.
He is assisted by Harry Element who is currently working towards an MSC in Geomechanics, & by Pat Fraser Stansbie, an expert in CAD drawing.
No matter the size of the project, we can advise, design & calculate your project. Our wide set of skills enables us to give you the information you need to lay any foundation.
