Failing retaining wall

Optera were recently engaged by our insurer client to design and build a remedial solution to a failing retaining wall on the outskirts of Bristol. Our investigations revealed the wall to be rotating due to the hydrostatic pressure build up behind the wall, caused by faulty and silted weep holes which were set too low in the wall in solid bedrock. Negotiating a road closure with the local authority, Optera have worked in the highway behind traffic lights, fixing dywidag rock anchors into the sound strata behind the wall. In addition, longitudinal bed joint reinforcement has been fixed into the wall to form masonry beams which bridge between anchors. Additional drainage provision has been built into our design. Optera operatives, practicing social distancing and other control measures have completed this project in challenging times, on time and budget, thousands on a potential wall rebuild.
