A retaining wall is a structure linked to the ground and subject to significant horizontal pressures due to the soil upstream, which can increase considerably in the case of inefficient drainage: a significant quantity of water modifies the characteristics of the soil and aggravates the pressure of the soil on the retaining wall.

The use of Laterlite Expanded Clay is particularly useful as a replacement for traditional aggregates for backfilling or embankment behind both new and existing retaining walls, as it reduces thrust, is highly draining and provides various additional benefits.

The reduced thrust and improved drainage provided by Laterlite Expanded Clay lightweight drainage fill has advantages in the design, construction or restoration and consolidation of most solid retaining walls or diaphragm walls, whether traditional gravity walls, reinforced concrete walls, reinforced soil walls, embedded metal sheet piles or vegetated walls, etc., as the internal and external stability of the wall is increased.
