9/2017 – Step by Step rock face wall
Step by step TERRAFORCE rock face retaining wall:
Terraforce rock face retaining wall in picturesque Cornwall, on a plot in the town of Rock, a holiday resort across the Camel Estuary from the fishing port of Padstow. Installed by Ross Campbell, Ross Campbell Contractors, the 4000-block wall is built with starter bar to the top of the vertical section, with concrete infill, a double block layer and no fines concrete infill for extra reinforcing.
The sloped section has a geogrid layer placed every second row of blocks. A perforated 110mm drainpipe drains out any excess water via two discharge points.
