Driven piles transfer their load to layers of rock or soil that have sufficient bearing capacity, and suitable settling characteristics.

Driven piles commonly support buildings, walls and bridges, and can be the most cost-efficient deep foundation method.

The long slender preformed and shaped material is installed by impact hammering, vibrating or pushing into the ground to a design depth or resistance. As an adaptable type of foundation, driven piles can be installed with compression, tension or lateral loads in mind, with consideration of structural needs, budget, and soil conditions.

CLL has the capability to drive:

• Timber piles up to 16m in length and up to 400mm in diameter
• Reinforced concrete piles up to 900mm in diameter and up to 18m deep
• Steel piles up to any size and length
• End-plated casing pipes

Our unique excavator-mounted pile drivers drop hammers weighing from 500kg to 2.2T.

This equipment is very mobile, enabling rapid work at reduced cost.

Our design also allows CLL to handle challenging sites which are beyond the scope of most ground improvement enterprises.

“There’s many different types of driven piling. We find the technique is particularly useful when there’s quite a depth of softer ground to eventually reach a harder layer. Often too driven piling is an excellent option where there will be lightly loaded or less loaded infrastructure. For a straight-forward foundation a universal column or tube may be employed. Alternatively we often use driven timber piles, particularly for ground improvement. This closes up gaps in the soil structure, densifying the soil.”

“It stands to reason that you have to know the spacings to achieve this consolidation. This is all part and parcel of the knowledge CLL brings to the job.”
