From strengthening weak bridges and filling embankments. Filling voids before excavation and even large networks of roads and encapsulation of utilities, Foamed concrete in its many forms is ever present, especially in ground work, construction and demolition.
Crossrail, HS2, Road bridges, rail bridges and airports. New builds and upgrading the existing. Propump engineering are continually requested to specify material for broadening applications. Whether the foam injected concrete is used to keep the overall weight load down, or even as a self-stabilising material the can readily be re-excavated, lightweight foamed concrete can be continuously poured. Requires no compaction and is mostly self-levelling.
Decommissioning of old terminals and filling of cargo tunnels under the main runway, Propump have produced materials for the widening of taxi-ways at Heathrow airport and the decommissioning of old service tunnels. Foamed concrete has been used significantly throughout the last 25 years at Heathrow Airport for expansion and upgrades.
Another reoccurring use of foamed concrete is for road bases. Propump have encapsulated many different utilities whilst pouring light weight ultra-low density foamed concrete for suspended roadways.« Filling Tunnels, and James Henry Greathead
