Barry Docks Drainage Works

Barry Docks Drainage Works

As part of the new drainage layout to the residential development of Barry Waterfront, Kaymac were contracted to install an outfall drainage system to the harbour wall from modular pontoon platform system.

The work was carried out from a modular pontoon barge which was manoeuvred into position using a work boat. The wall was approximately 2m thick and required 36 individual cores to be drilled to achieve the correct diameter for the outfall to be installed.

The harbour wall was then recessed and the pipe was pushed through the hole using an excavator from the landward side of the wall.

The annulus around the pipe was filled with a structural grout and left to cure. The surface of the recess was made good with a concrete repair mortar  and  the  flap  valve  was finally fitted to the harbour wall.
