Our polypropylene macro and micro fibres helped food waste recycling leader Biogen avoid corrosion in concrete pavements at its biogas plants.
At Biogen’s many biogas facilities across the UK, organic waste is fermented to make methane gas for fuel. The acidic liquid can corrode the steel fabric used in the plants’ concrete pavements. Biogen needed to find a stronger, longer-lasting fibre – and replace the pavements at one of its sites in just 12 weeks.
A ready-mix concrete company suggested contractor Toureen Mangan work with us, praising our tailor-made approach to redesigning concrete reinforcements. After careful calculation, we replaced the steel fabric with 8000kg of our Durus S400 polypropylene macro fibres, and 1000kg of monofilament fibre Fibrin XT. These strengthened the concrete to cope with heavy plant traffic and higher levels of freezing and thawing, while also avoiding corrosion.
The new fibre-reinforced concrete pavement saved around two weeks of steel fixing. And because we didn’t need to place and store in-situ steel fabric, traffic could move around the busy plants as normal. While bad weather delayed the project, our flexible designs helped Taureen Mangan get back on track and meet the tight 12-week deadline. What’s more, Biogen’s stronger, more sustainable concrete pavements will last longer and cost less to maintain.
