When used against retaining walls, maxit LWA will reduce the weight acting on the rear of the structure by at least 75%, in comparison to traditional fill materials.

This reduction in weight avoids potential sliding, overturning, slip and tilting or bearing failures and enables savings by increasing spacing between buttressing walls and reducing structural dimensions.

The bulk weight of the wall can also be reduced and more cost efficient, attractive materials can be used in place of costly, unattractive structural concrete.

The use of maxit LWA will also minimise the differential settlement between piled bridge abutments and the embankment fill. As it is a free draining material maxit LWA, can also eliminate the need for rear wall block drainage.

The ‘pull out’ resistance of LWA also makes it an ideal solution for reinforced soil retaining walls. Particularly when constructed over weak sub-soils or voids, this method can cut overall construction costs considerably.

1. maxit LWA backfilled against bridge abutments reduces loading on the underlying subgrade, exerts less pressure on adjacent pile foundations and prevents settlement irregularities.

2. Backfilled against a retaining or basement wall, maxit LWA settles less and exerts 75% less horizontal earth pressure than conventional fill materials.
