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.
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
