Strip Foundations

Strip foundations are a type of shallow foundation that we typically use for domestic projects, including new builds and extensions. These foundations can support load-bearing walls when the ground underneath’s load-bearing capacity has been evaluated and supports the project.

Strip foundations offer many advantages, including the fact that they are relatively inexpensive in terms of construction and materials. Our experts seamlessly install these foundations to ensure projects are well-supported and can continue swiftly.

Trench Fill Foundations

Trench fill foundations are typically used when constructing houses, garages and smaller commercial buildings. We manage these foundation installations by digging a trench around the planned space for the building and filling it in with concrete. 

These foundations are popular for many projects because they are quick and relatively easy for our specialists to construct. Trench fill foundations require less excavation than other foundation types and are suitable for various soil types. They also effectively distribute the weight of buildings evenly across the ground, which helps prevent subsidence.

Piled Foundations

Piled foundations are deep foundations with a depth of three times their width. They are created with long, columnar elements usually made from reinforced concrete or steel. These foundations are mainly used to transfer the loads from structures through weak strata onto stronger soil, increasing the foundation's effective size. 

Pileds foundations are often used for larger buildings and in circumstances where the soil isn’t typically used for large structures. They are also used when the soil isn’t suitable to prevent extreme settlement.

Raft Foundations

Raft foundations are made from large concrete slabs which can support numerous walls and columns. These foundations are commonly used when the strata is unstable or, as a result of this, a typical strip foundation would cover more than half of the ground area underneath the building. 

They are successful in domestic and, more often, commercial construction. At Onyx Contractors, we use these foundation installations to spread the weight of the building over the whole ground floor area of the structure in Guildford, Godalming, Farnham or any of the surrounding areas.
