Concrete Specification and Solutions
Van Learn about the specification of concrete and practical solutions to design requests. This webinar will address the specification of concrete in Ireland, concrete onsite testing, finishes and mix types. It will also address recommendations around the use of concrete in hot and cold weather. Finally, you will learn about the concrete services offered by Roadstone.

Foamed Concrete

Contact us for sales or technical advice on this product


Foamed concrete is a lightweight, highly flowable, limited strength mix, also referred to as flowable fill material. The mix contains a high and stable mass of air that reduces the density and significantly improves the placing characteristics giving it self-compacting characteristics with no requirement for vibration. Because of the high air content foamed concrete has excellent insulation, sound-absorbing and fire resisting properties. Strength grades of between 1 – 10 N/mm2 can be achieved making this mix ideal in applications where future excavation may be necessary. A versatile material foamed concrete is ideally suited to fill voids where limited, difficult or unstable access is a problem such as disused vaults, sewers and pipe lines or for neutralising redundant petrol/diesel storage tanks.

Key Features & Benefits
  • Ease of placement and finishing (particularly where access is limited)
  • Self-compacting
  • Cost effective compared with traditional trench fill methods
  • Good thermal, sound and fire resisting characteristics
  • Resistant to freeze / thaw damage
  • Reduced weight compared with conventional concrete
  • Neutralises and secures old fuel storage tanks
  • Fills disused vaults, sewers, pipe lines, culverts and shafts
  • Trench re-instatement
  • Insulating sub-screeds
  • Filling of temporary openings
  • Filling of arches in bridges and viaducts
