Mini rigs get houses in order

Foundations Contracts

A NOVEL piled slab foundation system is starting to capture a share of the buoyant housing market Abbey Pynford has secured NHBC technical approval for its innovative Housedeck piled slab foundation system, suitable for new-build houses of up to three storeys.

The system can be constructed with a suspended floor slab, which makes it particularly suitable where heave is an issue or where landfill gases or radon protection is required.

Additionally, the patented deck support units feature a stainless steel edge detail that allows bricklaying to get underway much sooner than a conventional construction - accelerating the overall programme.

The key advantage of the system is it is very clean and self-contained approach to house foundations. Furthermore due to the alternative sequence of working, says the company, the installation of piles and construction of the soffit system is not affected by adverse weather.

Abbey Pynford starts by laying down a blinding layer that acts as a clean, safe working platform. Abbey then tracks in a small minipiling rig to install the foundations, and herein lies one of system's main selling points.

'Many of our competitors seem to be going for bigger rigs, say 35-40t crawler cranes which require substantial piling platforms, whereas we've attempted to go in the opposite direction' says Nick Hodder, commercial director with the company's Housedeck foundation division.

'Provided pile depths are less than around 15m the small rigs are more than adequate for the lightweight structures.'
