maxit LWA’s ability to reduce settlement can offer massive benefits, reducing timescales from years to a few months for new or extended carriageways or for embankments and even, in some instances, eliminate settlement periods altogether.

Construction of embankments over weak and compressible soil deposits, where the loading of the embankment causes soil consolidation and settlement, is common.

Depending on the height of the embankment, the depth of the weak soil deposit and the consolidation properties of the soil strata, total settlements can be very deep and problematic in terms of road evenness, function and durability of the road construction.

In the most difficult cases, various combinations of soil strengthening techniques are available, for example, pre-loading, vertical drainage and deep stabilisation with piles - all of which are time consuming and costly to install.

By lightening the embankment with maxit lightweight aggregate, subsoil strengthening and lengthy settlement periods can be reduced or even avoided altogether.

1. Using maxit LWA on large scale cut and fill operations and construction on soft soils and bad ground, can overcome stability problems, reducing the risk of landslide and deformation.

2. Used in road embankments, maxit LWA exerts much lower horizontal earth pressures compared with other backfill materials, helps improve stability and reduce the need for counterfill.
