M & D Foundations
Mini Piling
Mini-pile systems can be used to underpin lightly loaded structures including properties affected by settlement. We tailor the type of pile and underpinning system to meet specific requirements - for example, the type of structure, general conditions, loading, access, etc. Mini-piling equipment can be used for work inside buildings and in locations where headroom is restricted to an extent which would make the use of larger piling systems impossible.
We provide two types of mini piling techniques, as follows.
Steel Cased Driven Piles
Where piling is used to underpin existing foundations or to support new foundations on unstable ground, we employ a steel cased driven pile technique.
Typical pile dimensions and loads available are:
- 100mm diameter - approximate SWL50KN*
- 150mm diameter - approximate SWL90-100KN*
Augered Piles
We use this system in conditions where driven piles are unsuitable, as in cases of settlement related to clay shrinkage or for tension piles in a cantilever beam system.
To install these piles M & D Foundations use a special track-mounted mini-pile assembly which can be operated inside domestic properties and in locations where headroom is as low as 2.4 metres.
We offer piles ranging from 100mm-300mm in diameter. Safe working loads are established dependent on the nature of the bearing strata, into which piles are founded. This type of drilling rig can also easily be adapted for down the hole hammer drilling to enable anchorage into firm strata such as mudstone, sandstone, etc.
Pile loads:
- Typical approximate SWL50-200KN*
