Topfoam is a lightweight, foamed concrete. Topfoam is a lightweight, pumpable concrete to encapsulate pipework or conveniently fill voids.
Topfoam foamed concrete has been specifically developed for void fill. Simply pour into place to the required level, Topfoam needs no compaction, has excellent insulating properties and can be delivered to site in conventional readymix concrete trucks.
Topfoam foamed concrete is highly workable and can be placed by either direct discharge from the mixer vehicle or via a standard concrete pump.
Topfoam is a low density, free flowing, easy to place foamed concrete for void fills and trench reinstatement applications.

Additional info
Topfoam Road is also available, developed for highway applications.
Topfoam Road is a free flowing concrete ideal for trench reinstatement compliant with HAUC ( Highway Authorities & Utilities Committee) legislation.
With Topfoam Road, no compaction is required and lateral support is restored to adjacent services. A wearing course can generally be laid within 24 hours.
Applications include cable and other utility trenches, carriageway excavations and HAUC reinstatements.
Topfoam foamed concrete can be engineered to deliver tailored requirements for density and end strengths dependent on project applications. Compressive strengths range from 1N/mm2 to 10N/ mm2 and wet densities range from 800kg/m2 - 1800kg/m2. Topfoam foamed concrete can be delivered as a base mix to specialist contractors if a lower density is required.
