Piles and Anchors - Roger Bullivant
Used for the installation of foundations where access is limited
- New foundations for Housing (Up to 3 plots at any one time) close to sensitive areas.
- Factory units for Mezzanine floors.
- The installation of foundations within factory units for heavy machinery where the settlement criteria is critical.
- For the construction of retaining walls, and retro-fit basements.
For the construction of retaining walls, and retro-fit basements.
Used within restricted areas for poor ground conditions, where deep foundations are impracticable. For extensions to homes and one off housing plots we offer a full design service including site investigation to meet NHBC and Building Control standards. We also design and construct foundations for machine bases, and mezzanine floors where access is limited.
Drill Bar Pile
This can be used in most ground conditions and is probably our most versatile pile. The drill bit and bar is sacrificial and are drilled to a designed length and filled with grout through the centre of the bar and drill head.
Overburden Drilling
There are several methods used for this type of drilling. These are used where the ground conditions do not allow a driven or an augered pile to be used, for example a quarry that has been backfilled in an uncontrolled manner. A permanent casing is drilled through the fill ground onto the rock head, dependent on the system used, the drill will then continue on into the rock to form the pile at the designed length, or the overburden drill is removed and another type of drill is used to complete the drilling into the rock head. The pile is then filled with a designed grout mix from the bottom.
Sectional Flight Auger
Used in ground conditions where heave may be a possibility, but the ground conditions do not allow the pile bore to stay open. Heave conditions will be designed out by increasing the depth of the pile and the reinforcement used. This pile is filled with concrete through the centre of the augers as they are retracted.
Top Driven Steel / Pre-cast
Used within restricted areas for poor ground conditions where deep foundations are impracticable. Extensions to homes, one off housing plots machine bases and mezzanine floors for example primarily used as an alternative to bottom driven piles to offer a higher load capacity.
Open Hole Auger
Used in ground conditions where heave may be a possibility, but the ground conditions will allow the pile bore to stay open. A plastic coated liner can be installed to a designed depth to minimise heave. Temporary casings can be used to support ground that may be unstable towards the top of the pile. This means the pile can still be filled with concrete from the top as the casings are removed.
