Construction of Flood Embankment
This project was to construct a new flood embankment to protect domestic properties and an electrical sub station adjacent to the River Roding.
The line of the embankment was set out and the topsoil stripped and set to one side. The clay based material was imported and keyed into the existing ground and then compacted in layers using the tracked excavator and vibrating sheeps foot rollers.
A Thames water storm water manhole was located within the line of the new embankment and so this was raised as part of the works along with a headwall and flap valve at the termination of the embankment at the river to drain any water accumulated on the back slope.
Once the structure was completed it was covered with imported topsoil and seeded with grass.
Warning markers identifying the structure as a flood embankment were also set in concrete along the top of the embankment.
