Alfarock is a modular precast concrete retaining wall system designed by engineers to provide a strong, reliable and cost-effective solution for retaining and landscaping projects of all sizes.
Its interlocking dry-stack design allows walls to be constructed quickly with minimal excavation, reducing installation time, labour costs and disruption on site.
Suitable for both temporary and permanent applications, Alfarock combines engineered performance with the appearance of natural stone, delivering an attractive, durable and maintenance-free retaining wall that maximises land use and long-term value.
Advantages of Alfarock
- Precast blocks manufactured under controlled conditions. No reinforcement necessary;
- Delivered to site ready for immediate installation;
- No scaffolding required during construction;
- Compact block design minimises excavation requirements, reducing earthworks and associated costs;
- Significantly faster installation than traditional retaining wall construction methods;
- In most applications, geogrid reinforcement is not required;
- Can be installed in virtually all weathers, helping to minimise project delays.
Design and Installation is available using approved contractor (Evogeo). All work is carried out, countrywide, to the highest construction standards while adhering to all health and safety requirements.
Designed for performance
- Specifically engineered for retaining wall applications;
- Suitable for simple and complex wall layouts;
- Engineered to Eurocode 7 (EC7) standards;
- Capable of constructing tall gravity walls without geogrid, depending on design requirements;
- Suitable for projects on land or in water;
- Available for walls of almost any height.
Case study
A retention pond development in Newtownmountkennedy, Co Wicklow, required an efficient and durable retaining structure to accommodate level changes associated with the stormwater management infrastructure.
The challenge
The project required a retaining wall system that could:
- Accommodate changes in site levels around the retention pond;
- Be installed quickly to maintain the construction programme;
- Minimise excavation and foundation requirements;
- Provide a durable, low-maintenance solution;
- Deliver an attractive natural stone appearance suitable for the surrounding environment.
The solution
Alfarock retaining wall system, delivering a:
- Precast concrete wall system;
- Modular and interlocking design;
- Mortar-free installation;
- Mass gravity retaining wall solution;
- Engineered retaining structure designed specifically for earth retention applications.
Key benefits delivered
- Fast Installation using standard site plant;
- Cost Efficiency with minimal foundation requirements and reduced site labour;
- Flexible Design featuring curves, terracing, changes in alignment and geometries;
- Aesthetic natural stone look that integrates well with landscaped environments. Inclusion of planter blocks allow for natural vegetation growth and a capping units to support fencing;
- Sustainable – Modular design reduces material waste and site disruption;
- Alfarock supplied in conjunction with many of our other products, including hydrobrakes, stone, concrete and other materials, demonstrating Roadstone’s extensive range of products and solutions.
Outcome
The Newtownmountkennedy retention pond project demonstrates the suitability of the Alfarock system for stormwater and SuDS-related infrastructure where construction speed, value engineering, durability and appearance were critical project requirements.
The project showcases how modular retaining wall technology can provide a practical alternative to conventional reinforced concrete solutions while maintaining engineering performance and visual quality.
