Soil Retention, M4/M5
Client: Highways Agency
Date: June 2006
Product: Bespoke designed, prestressed panels
FP McCann assisted with a successful completion of work for the edge of the motorway on the hard shoulder. 570 linear metres of concrete was erected into a pre-formed slot in the foundations.
An 11m2 panel was used to provide the required height of wall in one unit. The manufacturing process was made more complicated as the panels required skewed ends and simulated central joints. As a result FP McCann pioneered the use of mat formers to obtain a feature finish.
Achieving a decorative finish on prestressed panels is technically much more difficult than on a precast unit but the resulting panel is pleasing to the eye and has all the strength and benefits of prestressed concrete which exceeded client requirements.
