Whena crack opened up on this owner's wall he called us in. With engineer inspection and design to correct, we resealed the crack , dug behind the wall to correct the drainage issues and topped up the rock to stabilise the wall and to bring the wall back to it's original design.
Over time rock slumps and walls become destabilised. It is very important canal waterfront owners realise the importance of checking their walls and ensuring their wall is still functioning as it should.
The crack was allowing material to flow through from behind the wall. The owner had noticed the beginnings of subsidence.
Using the excavator (and a little manual labour) the effected section of the wall is given a new geofabric lining. The lining is topped and with a new layer of gravel (to allow water to drain behind the wall), back filled and grass reinstated.
Engineer report noted the rock was no longer supporting the wall at the level it was designed to- rock top up was final step in the repair.
Above- before and photo below is after the rock top up.
