Slipform retaining wall
Retaining walls can be slipformed in either of two profiles:
- Mass profile, where the external face is vertical, and the rear face is battered.
- ’L’ shaped profile, where both the external face and the rear face are vertical, and anchorage is achieved with a ‘toe’ at the bottom of the rear face.
- DCB face profile retaining wall is a system combining our Vehicle Restraint System with battered or ‘L’-shaped rear faces for retaining heights of up to 1.4 metres.
We have slipformed retaining walls from 0.9m right up to 2.4m – which is the highest slipformed retaining wall in Europe.
On the M25 Section 4 project, installation of our 2.4m wall saved having to transport several thousand tonnes of excavated material to landfill, resulting in a considerable cost saving and significant environmental benefits.
Key statistics:
We have been able to transfer the skills developed over 40 years of slipforming to construct slipformed concrete retaining walls up to 2.4m high. This technique offers a high output, high quality retaining wall solution. Outputs have been consistently higher than industry standards.
With our in-house expertise, the slipform moulds can be adapted to suit the required section and level of reinforcement.
Benefits of slipformed retaining walls include:
- Reduced land take compared to earthwork slopes
- Fast rate of construction
- Fewer temporary works
- Efficient use of plant and materials
