Poole Sewage Treatment Works

Wessex Water’s treatment works treat millions of litres of sewage every day.  Southern Concrete Services were contracted by Damar Group to assist in the renovation of a storm water tank at Poole Sewage Treatment Works.

Scope of Works: Repairs and water-proofing of floor joints and wall cracks to the concrete storm water tanks.

It was detected on the initial visit the storm water tank had not been used for a considerable time and consequently areas of existing expansion joints material had broken down and were now failing.  In addition to this, cracking had appeared in the tank walls.

The works consisted of removing the existing failed product and carrying out patch repairs where concrete had deteriorated within the joints.  The surface was then ground off using diamond tipped floor grinders.  This was to remove all grime and debris to ensure good adhesion for the bandage work.  DW2 approved adhesive and hypalon bandage was applied in accordance with the manufacturers’ recommendations over the wall joints and wall cracks.

The storm water tank will now competently with hold the forces of holding water when required.
