Contiguous Piled Walls

This is a widely used form of construction where contiguous walls are constructed with small spaces between adjacent piles where the size of the space is determined by the nature and condition of the soil. At Performance Foundations we use this method of piling on projects such as:

• The safe excavation of basements
• Ground stabilisation work (such as working on a hill or incline)
• or when you need to ensure that you maintain the ground where there is an adjoining property

This is due to the fact that the main advantage of this system is that it does not cause vibration which can destabilise existing structures.

We use two methods of bored piling techniques for contiguous piled walls, CFA and rotary. Where the available working area dictates that basement excavation faces must be vertical, these two techniques provide special advantages. Both methods are technically effective and are a cost effective method of providing temporary or permanent means of retaining the sides of bulk excavations, even in water bearing strata.

Contiguous piled walls can be designed to accommodate vertical loads in addition to horizontal forces when they are used in permanent works and the construction techniques for both methods are the same as for foundation bearing piles.
