Precast House Foundations

Precast House Foundations


‘Offsite Construction’ brings the advantages of improved quality, better Health & Safety, greater speed of construction and simpler construction processes to the building site.

Terradrive Piling & Foundations Ltd’s Precast House Foundation System is the result of the needs of the house building industry for a solution to the difficulties imposed upon them by spiralling labour rates, acute skills shortage and ever increasing performance demands (both time and economic).

The system combines precast concrete piling, precast concrete pile caps and precast concrete ground beams, manufactured under controlled factory conditions employing the very latest concrete technology, to produce a tailor made house foundation solution.

Advantages include;

  • Improved Health & Safety,
  • Greater speed of construction
  • Higher standards of quality and reliability,
  • Greater predictability of costs and programme,
  • Less disruptions to the construction process (not weather dependent),
  • Reduced environmental impact (no spoil on site or wasted materials),
  • Simpler construction process,
  • Reduced reliance on expensive, scarce traditional trades,
  • All delivered in one sub-contract package.

Restricted Access Piling

Restricted Access Piling


Restricted access piling utilises a wide range of mini and medium size piling rigs to install piles and foundations on restricted access sites.

If you have a property with piled or deep foundations, mini piling will often be less expensive than digging conventional foundations and without exception will always be quicker, easier and cleaner.
Many houses built in recent years have relatively deep foundations and very little working room around them making digging for foundations for extensions very difficult.

There can also be considerable risks of causing damage by digging close to your neighbour’s property or even your own.

The current high cost of removing and disposing of spoil makes mini piling very cost effective.
Our light and compact rigs can get around houses with very limited access. The larger rigs only needing a 900 mm (3 foot) wide pathway.

Mini-Piling & Under-Pinning

Mini-Piling & Under-Pinning



Mini-piling solutions are ideal for foundation problems such as:

  • In limited access locations such as house extensions and conservatories where spoil excavation and removal would be both difficult and expensive
  • In built up areas where noise and vibration are a consideration and are particularly costs effective when compared to conventional systems
  • In limited headroom locations within buildings for alterations to existing structures or for new work such a lift pits, machine bases, etc.
  • In all small piling contracts such as foundations for a single house where the cost of mobilising large equipment and the cost of the site preparation required would be a problem.



The Underpinning solutions available include a number of tried and tested systems incorporating Mini-Piling and reinforced concrete beams or slabs, some which can be carried out entirely from outside the existing building, minimising disruption and therefore cost.

Settlement or subsidence problems tend to be specific to a particular property so the underpinning solutions we propose are individually designed to suit.

The underpinning techniques can be used for the stabilisation of failing foundations or for the upgrading of foundations or slabs to allow increased capacity for a change of use.

Precast Concrete Driven Piling

Precast Concrete Driven Piling


Precast piling offers consistent quality from the first pile to the last which can be seen and verified prior to installation. Driven precast piles maintain their shape during installation. They do not bulge in soft soil conditions and are typically not susceptible to damage from the installation of subsequent piles.

They are cost effective, versatile, they improve ground conditions, are self proving, adaptable and environmentally friendly.
