Soil Reinforcement Project on Major Northern Ireland Roadway

A8 Belfast MacRes Sept 13 (20)

Maccaferri’s MacRes and Paraweb systems were successfully used in the construction of a network of reinforced-soil retaining walls in the A8 route, from Larne to Belfast in Northern Ireland.

Civil and geotechnical specialists from Maccaferri UK & Ireland constructed a network of reinforced-soil retaining walls as part of the upgrading of the strategic A8 route from Larne to Belfast in Northern Ireland.

The A8 is a route of strategic relevance forming part of the Eastern Seaboard Key Transport Corridor and is classified as one of the key Euro routes, with nearly 17,000 vehicles in transit a day.

Maccaferri UK & Ireland built a network of 16 reinforced-soil retaining walls which form abutments facings and wing walls to 8 new structures constructed as part of the new works.

The walls are constructed using Maccaferri’s own MacRes system of large, concrete facing panels [pictured], installed in conjunction with high strength Paraweb geosynthetic reinforcement, manufactured by Linear Composites, also a Maccaferri subsidiary.

The MacRes/Paraweb reinforced soil structure is a system extensively used outside the UK with over 500,000sqm of walls completed worldwide, including the Redding viaduct and Forth Bridge Replacement Crossing.

Paraweb is amongst the most tried and tested geostrips in the world offering 120 year design life and high performance and high resistance to physical, chemical and biological conditions.

Lagan Ferrovial Costain, a joint venture by Lagan Construction Group, and Costain, were particularly keen to work with us as we provide a fully indemnified, combined design and construct package, which is a service that’s not readily available for reinforced soil, concrete panel structures in UK and Ireland.
