PROPUMP FOAMED CONCRETE FILLS VICTORIAN UNDERGROUND WALKWAY

When a disused underground walkway in Eastbourne required infilling to prevent the road above from collapsing, Propump Engineering’s foamed concrete proved to be the ideal solution to strengthen and stabilise the road.

Believed to be an undercover route for guests in the Queen’s Hotel to get to the nearby Royal Hippodrome Theatre or possibly a staff entrance, the Victorian walkway beneath Collonade Gardens had rotting steel I beams and jack arch supports which were structurally unsound. With the safety of the road users paramount, Propump was appointed by East Sussex County Council and contractor Kier May Gurney to deliver a foamed concrete solution.

Propump supplied 150m3 of foamed concrete at a density of 1,100kgs/m3 and a strength of 1-2 N/mm2 which was required to complete the infill of the disused 40 metre long walkway beneath Collonade Gardens.

‘Foamed concrete was by far the best option to fill this underground walkway.’ commented Thurston Yapp, Structures Engineer, East Sussex County Council. ‘Kier May Gurney chose Propump with their extensive experience, to work alongside their own team, to deliver a thoroughly successful solution.’

Increasingly popular with designers and engineers, foamed concrete is perfect for filling voids where access is difficult or when a lightweight mix is needed to meet restricted loading limits. Its most common applications include bridges, floor and roof screeds, pre-cast panels, sewers and tunnels.

With the Victorian tunnel now filled with foamed concrete, Propump used their extensive experience combined with a dedication and philosophy to work with Kier May Gurney team to deliver a thoroughly successful solution.
