Bored pile retaining walls have many uses, basement construction, cut and cover bridges, bank stabilisation and road/rail cuttings, but the system which you may need will depend heavily on certain factors; ground conditions, retained height, ground water and deflection.
At Advanced Mini Piling Systems, we provide:
Rotary Bored Contiguous Piled Walls
Piled Retaining Walls are a very cost-effective way of forming a retaining wall, as there is reduced bulk excavation with maximum underground space. Walls can follow complex layouts and our specialist rigs can perform with a minimum working requirement of 500mm to the face of the perimeter. (Distances can be further reduced depending on certain factors.)
Large diameter and mini piled cast-in situ retaining walls, give an economic and efficient way of constructing, permanent or temporary piled retaining walls. These walls are ideally suited for deep basement construction in the ever-expanding basement industry in London, as they can be bored and cast in restricted access and open site conditions, and where adjacent structures require support. Which is perfect for domestic projects as the piled retaining wall, can be bored and cast parallel to the party wall, retaining back neighbouring properties, giving the client maximum underground space.
Contiguous Piled Walls are suitable, where the ground water level is below the depth of excavation. It is the most economic and fastest method for piled retaining walls and the piles can be cast at 150mm greater than the diameter of the pile be used, which will leave gaps of soil once the excavation is complete, but will then have a reinforced concrete lining applied to prevent long term water ingress.
Where the ground conditions are unstable and the underlying clay is without ground water, temporary liners can be installed and removed after pile has been cast. This method is more economic and efficient than mini piled hollow stem.
