Do I need piling for my extension?
Piled Foundation: When the soil is unstable or incapable of bearing the load on its own, a piled foundation will create a much stronger support structure on which to extend your house. If the soil has much sand, clay or peat, this will be the most effective way of building out the foundation.
How deep can mini piles go?
A mini pile generally has a diameter of between 100 and 600mm and can extend to depths of over 50m.
What is mini piling?
Mini piling is a type of piling that has a smaller diameter than standard piling. As a result, they are light and affordable while still being able to withstand high weights. The most common kind of tiny piling is a hollow steel shaft fastened or drilled into the ground.
How do mini piles work?
Mini piling works by digging into the ground with the appropriate apparatus, lowering the concrete pile into the hole and pouring concrete gaps between the pile and the earth.
What is a floating pile foundation?
A floating foundation consists of boxlike rigid structures set at such a depth below ground that the weight of the soil removed to place it equals the weight of the building; thus, once the building is completed, the soil under it will bear the same weight… In construction: Foundations.
Do conservatories need piling?
Using piles for the foundations of conservatory may seem excessive to some, but in an increasing number of cases it is the most efficient, economical and best solution. If the ground conditions dictate deep foundations and/or there is no access for a sufficiently sized excavator, then piles can be the best way forward.
Are micro piles driven?
They can be driven or screw piles and tend to be used where access is restricted, for example underpinning structures affected by settlement. They were first used in Italy in the 1950s in response to the demand for innovative underpinning techniques that could be used for historic buildings and monuments.
How can I get mini piles?
For the most common type of mini piling a hollow steel shaft is screwed or drilled into the ground. On top of this, grout or concrete is poured in for the pile, while the soil is supported throughout by the steel shaft. Unlike traditional boring methods, no extra supports are needed, even in weaker, looser soil.
How long does mini piling take?

What are mini pile foundations?
Minipiles are a deep foundation element constructed using high-strength, small-diameter steel casing and/or threaded bars.
How much do screw piles cost?
How Much Do Screw Piles Cost? On average, screw piles (helical pier) cost $250 per standard screw pile That price includes the full installation, brackets, and a helpful little engineering report at the end.
What are anchor piles?
Tension piles, also known as uplift piles or anchor piles, are a type of pile foundation that is used to resist uplift forces that might otherwise cause it to be extracted from the ground. Uplift forces can develop as a result of hydrostatic pressure, seismic activity or overturning moments.
