Your garden, considered

Retaining walls hold back more than soil

Retaining walls hold back soil and water pressure, which grows with height. Footings, reinforcement and drainage behind the wall prevent bulging and collapse.

We design the wall for the height and soil, add drainage and backfill, and finish it to suit the garden.

In Carshalton, sloping lawns can be terraced into patio, lawn and planting levels.

Materials & possibilities

Retaining wall options

Material depends on height and style.

01

Timber sleepers

Natural

Quick to build for lower walls.

Rendered or faced, for higher walls.

03

Gabions

Stone-filled

Water is the enemy

Most retaining wall failures are caused by water building up behind them. We install free-draining backfill and drainage outlets on every wall.
