Redi-Rock™ Modular Flood Protection

To answer the national challenge of rising water levels, Marshalls CPM offers a range of flexible low cost, high quality solutions based on their innovative Redi-Rock™ interlocking modular wall system.

Whether looking to heighten river banks, build new sea walls or construct flood plain defences, Redi-Rock™ offers considerable benefits over alternative solutions, not least the aesthetically pleasing finish that Redi-Rock™ offers enabling it to blend perfectly into the local environment.

Redi-Rock™ flood protection walling offers

  • Quick and economical installation
  • Overall cost savings on projects typically more than 30% compared to alternatives – In fact, many projects have achieved even greater savings when taking into account massive labour savings, less land take and faster installation
  • Dry laid with no cement, formwork or shuttering and minimal foundations
  • Can be installed in any weather and into water
  • Minimal delays to work and schedules
  • No maintenance
  • Natural stone appearance to blend into or complement local landscapes

Concrete has a proven track record of performance in water applications, and the modular blocks are 100% concrete and not steel-reinforced. As the blocks are dry laid, they can be easily moved should the situation on the ground change.

Water applications benefits:

  • Pre-cast strength against freeze-thaw cycles
  • Massive blocks with in-built strength
  • Quick and economical installation
  • Dry-laid, no mortar
  • Competitively priced
  • No maintenance
  • Natural stone appearance to blend into or compliment local environments

Redi-Rock™- Waterways & Shoreline Defence

As past summers have shown, at least ten per cent of all land in England lies within areas at risk of flooding. This includes large areas of Eastern England and much of the cities of London, York and Hull. There are tens of thousands of buildings at risk including the Houses of Parliament.

Predictions for the next 50 years estimate that water levels in England will rise by around 0.3 meters.

To help answer this national challenge, Redi-Rock™ provides flexible solutions that offer savings in economy and time-scale when compared to traditional methods.

Shoreline Protection and Erosion Control

The proven track record of concrete performance in water applications makes Redi-Rock™ a fitting match too many challenges because the blocks are 100 per cent concrete and not steel reinforced. Most severe water conditions can be addressed by using different cement or additives in the concrete mix to guard against water erosion.


Canals and rivers can utilise Redi-Rock™ blocks. Tow paths and river banks can be reinforced with a Redi-Rock™ walling solution that aesthetically compliments the environment. Redi-Rock™ is a quick to install and economically attractive solution that has the added advantage of being very ascetically pleasing in the country environment.

Flood Plain Defences

Redi-Rock™ is ideal for flood plain defences since as the seas rise so will the rivers and low lying land will flood unless protected. Redi-Rock™ concrete blocks are ideal for this type of flood defence. In the UK, the Environment agency has specified Redi-Rock™ for many projects including a large scheme in Newcastle.

Marshalls CPM is able to offer Redi-Rock™ modular walling in BIM (Building Information Modelling) which is now a requirement for all government construction projects.

Redi-Rock™ is an engineered retaining wall system that looks great, is easy to install, and will stand the test of time. Marshalls CPM is the exclusive manufacturer of Redi-Rock™ retaining walls within mainland UK, including England, Scotland, and Wales. We lead the retaining wall market in the UK with extensive production facilities across the UK.
