Housedeck on Brownfield Site

Client: Mears New Homes

Size: 2,625m2

Duration: 12 weeks

Scope of work : Concrete working surface, Rotary Displacement Piling, voided Housedeck RC slab with Brick Support Unit

The housing developer needed to minimise the volume of spoil removed from this brownfield site and so selected the Abbey Pynford housedeck system supported on Rotary Displacement Piles (RDP).

The RDP technique has been developed by Abbey Pynford to construct hollow stem injected bored piles using our fleet of midi piling rigs (circa 13T).  These piles produce virtually no spoil arisings and the use of midi rigs typically removes the requirement for a piling mat, further reducing the volume of spoil removed from site.  In addition the flat slab Housedeck system ensures that below ground drainage can be installed as shallow as possible.

A suspended raft slab constructed upon our re-usable Deck Support Units with perimeter Brick Support Units and air vents provided a complete heave protection system to meet warranty provider requirements.

The Housedeck system suits any superstructure construction and on this project timber frames with external brick skin was used.
