Performance Foundations provides a range of retaining wall construction services in London and Sussex

Retaining walls are built to hold back ground and stabilise slopes. They provide useful areas at different levels, such as for a terrace, basement or new building. As piling and groundwork experts we install reinforced concrete walls when there is no access restriction to the site and an area can be safely excavated. Otherwise we install contiguous piled walls.

Piled retaining wall or RC retaining wall?

For retaining walls in construction projects, a structural calculation is essential for understanding the type of wall that will be needed to hold back the earth on the site. A clear site is ideal but at Performance Foundations we are experts at working on sites with limited access.
A combination of site considerations and the purpose of the retaining wall will dictate whether a piled retaining wall or rc retaining wall is the right approach. We will undertake a comprehensive site visit to make sure to provide an effective and long-lasting solution.

What are the uses of retaining walls?

Garden retaining walls can be simple jobs if they are to hold back a relatively small volume of soil, and are not required to bear any load. Tiered gardens and terraces require retaining walls of appropriate construction, and if the garden landscaping project involves significant loads and slopes, a reinforced concrete or piled wall will be the approach to take.
Basement projects invariably involve excavation and the construction of load bearing retaining walls. The structural calculation will take into account the vertical load and the horizontal pressure from the retained soil. We will advise and quote for the solution most appropriate to the requirements of the project. Building projects involving retaining walls have the same considerations.

What are types of retaining wall?

The principal types of retaining walls are:

RC retaining walls

Reinforced concrete retaining walls are created on level footings with the use of reinforcing metal frames with concrete poured over. They can create highly robust and enduring retaining walls for building and structural work.

Piling retaining walls

The use of concrete piling creates a strong, enduring structure for a retaining wall for all building and external purposes. At Performance Foundations we provide a range of different piling solutions to meet the requirements of multiple construction projects.

Gravity retaining walls

Gravity walls are generally constructed with concrete blocks which have enough collective mass to hold back slopes and resist movement and slippage. They need to be built on solid, level footings and built with care.

Cantilever retaining walls

Cantilever walls use sections of steel-reinforced concrete which form a vertical wall and an L-shape or T-shape. The part of the wall under the soil is locked in place by weight of the soil.

Anchored retaining walls

Anchored walls are sunk into the earth and held in place by cables driven into the retained soil.

The Performance Foundations approach to retaining walls

Performance Piling’s construction of retaining walls is carefully considered, designed and constructed. We take into account the tendency of the retained material to move down the slope because of gravity, which creates lateral earth pressures, and we look into proper drainage which will eliminate hydrostatic pressure on the walls.
Our retaining walls are designed to ensure stability against overturning, excessive foundation pressures, sliding and water uplift.
