Maintaining levels within any foul or surface water drainage system can be difficult when the drain runs across a soft soil site.

maxit LWA can be used as a lightweight pipe surround, reducing the pressure to the underlying soil sand minimising the likelihood of irregular settlement.

Surrounding utilities and drainage carried within bridge beams either side of the carriageway with maxit LWA is a lightweight, simple to install alternative to that of sand traditionally used to support and insulate these services.

The added benefit of using the lightweight round granules of maxit LWA as a pipe surround is that there is little danger of any damage to pipelines during backfilling and the likelihood of damage from settlement is also reduced.
