Driven precast piles are installed using impact or vibration hammers to a design depth or resistance.
Process
Driven piles can be made of precast concrete or steel H-piles. In some cases, pre-drilling may be necessary in dense soil to allow the pile to reach design depth. They can be installed in one length or jointed for deeper piles.

Common uses
- Can be used for all types of construction, particularly in aggressive soil conditions
- Well suited to sites where the ground conditions are highly variable as they are driven to a set or pre-determined resistance
- A good foundation choice when you have very thick layers of soft soil and/or a high water table that would be problematic for a traditional drilled pile
- Large pile sizes can be used for: wind turbines and pylons, river bridge foundations, bridge abutments and piers, marine construction
Advantages
- No spoil so often the most cost effective piling solution for contaminated or brownfield sites
- Rapid follow-on construction
- Extensive range of pile sizes
- Piles are pre-manufactured to factory standards, the required length and standard conformity
- Piles may be installed to significant depths > 40m
- Unaffected by ground water
- Widely used and suited to most ground conditions
Quality assurance
Keller has access to an extensive selection of pile sizes to ensure an optimum design solution and can draw on extensive experience and resources to ensure successful project delivery.
We also use the most up-to-date, enclosed hydraulic hammers, which keep noise disturbance to a minimum..

Keller have installed approximately 1800 driven precast concrete piles for four new apartment structures for Weston Homes. The displacement piles have been driven through both cohesive and granular ground to achieve sets on the limestone bedrock in two separate visits to site.
