Precast Caps

Roger Bullivant Limited is one of market leaders in the design, manufacture, and installation of Precast Segmental Piles. To complement our range of piling solutions, RBL provides Precast Caps, a flared head, which can reduce the design thickness of an insitu slab. Pile centres can be adjusted to allow for the optimum load on piles for the most cost-effective pile size. This package solution includes design, manufacture, setting out, cropping and installation.

Installation can be carried out before or after the building is watertight, so off the critical path.


Roger Bullivant Limited’s Precast Cap solution is ideal for commercial projects, like sheds, to support internal concrete slabs. They can also be used as an internal piled slab replacement as well as an external concrete hardstanding.



Following installation of precast piles, RBL excavate locally around pile position. Driven Precast Concrete Piles are then mechanically cropped to cut off level. The central bar is then cut to length, so it does not protrude above pile cap level.

The Precast Cap is then lowered onto to pile, seated on an even grout bed achieving a final level tolerance of +0/-10mm.

RBL or the attendant groundworker utilising the excavated material, back fills locally around pile location, compacting in layers using a small ‘vibrating wacker plate’ ready to receive a membrane to go under insitu slab.


WHY USE Precast Caps?

  • Reduces on site activities once the precast pile is cropped, shuttered and concrete cap is placed
  • Package includes design, manufacture, setting out, cropping and installation.
  • Factory quality products utilising low carbon concrete
  • Non-weather dependant
  • Reduced site waste and wash out
  • Various precast pile cap sizes depending on load requirements.
  • Reduces the depth of insitu concrete slab, providing savings to the project
  • Takes the operation off critical path and can be installed once structure sides and roof on.
