What are Preformed Substructures?
Preformed Substructures are a modern method of construction that uses off site manufacturing to ensure the quality of complex structural reinforced concrete components. Similar to pre-cast methods but without the heavy haulage and lifting requirements. Its combined with the GoliathTech screw / helical piles to provide a super efficient and superior foundation system ideal for heavy duty loadings even in poor ground conditions and can be deployed through access as narrow as a single doorway.
They are well-suited for new builds, extensions underpins, restricted access, projects with TPOs (tree protection orders) or root protection zones, passive house projects, piers, garden rooms, solar projects, Modern Methods of Construction (MMC), prefabricated buildings and more.
About Us
We don’t just supply and install screw pile foundations, we offer a full range of high quality and complete foundation and retaining wall solutions with all the associated groundworks to both the private and commercial sectors.
Our screw pile foundation services covers large parts of the South East of England.
We use offsite manufacture and modern methods of construction to provide a high quality product, with an emphasis on support and fast lead and installation times.
Benefits of a Screw Pile Foundation System
Restricted Access Foundations
We can install a full foundation system for high load applications through a gap of just 800mm – the standard width of a door – meaning sites with restricted access become viable for construction
Warranty Included
Warranty included on the GoliathTech high-quality galvanised steel ground screws.
Low impact
Kinder to the environment with far less excavation and concrete than traditional poured concrete foundations – reducing carbon footprint
High Quality
Rapid screw pile installation
Less disruptive
We don’t use large noisy equipment and the offsite manufacture reduces need for loud cutting – great for noise sensitive areas with neighbours

Installation Case Study
Installation Case Study
Our Completed Project in Ealing
- 1
Following an onsite survey we proposed to utilise a helical pile foundation with reinforced concrete capping beam and to balance the proposed surrounding landscaped ground levels slightly.
- 2
The result was a foundation system which required minimal excavation and could be install quickly and efficiently (within 4 weeks).
- 3
In conjunction with the adjusted landscape levels it meant no material had to be transported from site.
- 4
Only the screw piles went down into the root areas resulting in minimal impact and allowing construction over root protection zones.
- 5
The ground beams were manufactured offsite which meant they could be installed quickly and efficiently with no cutting on site resulting in less noise and disruption to the local residents.
- 6
We also installed the cess tank and sustainable urban drainage systems.

Chris and the team at Preformed Substructures completed a complex screw pile foundation installation for our house extension in Surrey. An excellent job considering the very difficult ground conditions for the build
