Redi-Rock walling innovation to tackle flooding
In July this year, the Government announced a multi-billion pound investment programme to tackle long-term flooding.
The £5.2 billion plan is to create around 2,000 new flood and coastal defences to better protect 336,000 properties in England by 2027. The plans also include £200 million for innovative projects such as sustainable drainage systems and nature-based solutions like temporary and permanent water storage areas.
A recently completed water management project was located in Garstang, Lancashire where Floodsafe Projects built a flood defence scheme to stop seasonal flooding that had become a real issue for local residents.
Local residents and councillors had set up a Flood Action Group following flooding in the local area to look at the possible funding available to construct a flood defence bund that could be extended to defend the entire village.
With the involvement of the Environment Agency (EA) and local authorities, several options were explored, and due to the nature of the surrounding area, being of agricultural land, and the abundance of working space, the final design, which covered over 600 meters of flood defence, was agreed.
The design consisted of a combination of an earthen raised bund through the agricultural land, and a 1.5-metre high Redi-Rock modular block wall, complete with grates and a demountable barrier, where the line came close to a domestic property.
Contractors Floodsafe Projects completed the project, which is adjacent to the River Wyre, a major ‘A’ road and the properties of three landowners.
Now complete, the flood defence project is protecting three landowner’s properties and preventing the flow of floodwater from the River Wyre onto the road, where it had previously flooded into 58 properties, causing flood damage.
The 70-meter wide by 1.5-metre high wall was built using the latest walling development from Marshalls CPM, with Floodsafe being one of the initial consumers in the UK to install it. The flood wall is based on the Redi-Rock concrete block walling system, with Floodsafe using a ledgestone finish that gives a random textured natural stone looking face.
Laid on a reinforced concrete strip foundation, the hollow blocks allow for a steel reinforcement and concrete infill to be used, allowing for quick installation. This protected the surrounding property from floodwater whilst still enhancing the look of the local area.
On completion of the wall, Floodsafe Projects commentated; “this is the first time we have used the Redi-Rock walling solution after seeing it at an exhibition. We have been impressed with its ease of installation and the help we have received from the team at Marshalls CPM, from design to delivery. They have been with us at every step of the way, answering any questions from the EA or us. The installed wall went in quickly and looks great, the owners of the property are very happy.”

Innovation Award for Highways England
On smart motorway schemes, there is a requirement to construct retaining wall solutions at locations where the verge needs to be widened for gantry bases, technology sites or emergency areas but the verge is not flat ground and is either an embankment or a cutting.
On the M20 J3-5 & M23 J8-10 smart motorway schemes, Kier Highways had 2.9km of verge that needed to be retained in cuttings and it would have been easy to use tried and tested retaining wall methods (including bored piles, sheet piles or gabion baskets) but they were determined to find a better, more innovative method.
They investigated various retaining options including Redi-RockTM modular blocks, which gained Highway Authorities Product Approval Scheme certification for use on UK highways in 2018, and it was chosen as their preferred solution. The Redi-RockTM modular blocks have realised verified efficiencies of over £16m for Highways England compared to conventional retaining wall solutions. Installation is simple, as the blocks slot together similar to lego and the safety, quality, environmental, programme, logistical and commercial benefits they bring make a compelling case for using modular blocks.
The prefabricated concrete Redi-RockTM blocks are stacked to form a gravity wall and are precast with domes and grooves which lock together forming a mechanical key. Blocks typically weigh a tonne and are craned into position using a cast in lifting loop. They are non-grouted, dry placed, and rely on gravity for stability. The units decrease in depth higher up the wall whilst the front block face remains the same size. The units with a design life of 120 years are BBA approved, CE Marked, are British Kitemarked by PAS 68 certification and have approval from the Highway Authorities Product Approval Scheme (HAPAS) for use on UK highways.
Following the initial research reports generated collaboratively during early contractor involvement with Highways England’s designer Jacob Atkins Joint Venture, it was clear that if delivered well the Redi-RockTM modular blocks would deliver many benefits but as they had not been used previously on Highways England’s network there was still a lot of work to be done. This collaborative approach continued with their supplier Marshalls CPM to develop the product into a solution that met all client and designer requirements. By thinking innovatively and working collaboratively their team delivered a product that is new to the Strategic Road Network, pleasing to look at, and will form an attractive, less industrial roadside feature than other retaining options while ticking all the boxes for client Highways England.
Redi Rock ‘Modular Block Retaining Walls’ have delivered independently verified efficiencies of over £16m on the M20 J3-5 & M23 J8-10 smart motorway schemes
Redi Rock blocks have many environmental benefits. The blocks are made of 25% recycled material, they are laid dry without cement products, they require minimal foundations and walls can be de-mounted, with blocks used again in a different configuration, meaning they do not need to be disposed of.
The M23 J8-10 SMP has an AFR of zero and has currently worked over 1.5 million hours without a Lost Time Incident and there have been no near misses or incidents related to the Modular Block Wall operations
About the Innovation Award:
Innovation is widely recognised as the critical factor for increased and sustained productivity and growth. It demonstrates an organisation’s confidence, capacity and appetite for improved performance and productivity gains. Innovation is most effective as a holistic approach that identifies both demand and ideas and is most successful when supported by collaboration between customers and the supply chain.
