Fluid-fill concrete simplifies the process of laying pipe and cable by surrounding those with a tightly packed shell that provides protection from the elements, prevents settling, and enables crews to work quickly.

Conventional concrete is difficult to use for such purposes, but technology has developed superplasticizers, chemical additives that enable fluid-fill concrete to flow into tight spaces, without losing any of its inherent strength.

It’s provided extremely useful recently on London’s Crossrail project in stabilising buildings at ground-level effected by the deep-level tunnelling.

One of the many advantages of Fluid-fill concrete is that it can be pumped long distances, into places that are impossible to reach with simply a truck, and because it’s quite light it can be pumped to great heights too.
