DALROD UTILISES BRAWOLINER TO COMPLETE A CHALLENGING RENOVATION PROJECT NEAR ELY CATHEDRAL

DALROD UK Ltd, with offices in both Peterborough (Head Office) and St Ives (Cambridgeshire) and depots across East Anglia, the Midlands and the North East of England, has once again proved itself as a leader in the drainage maintenance and repair field by successfully completing a technically challenging job, with the minimum of disruption, close to historic Ely Cathedral, using trenchless lining techniques.

THE PROBLEM

The problem was that some 5 years ago pipeline survey works highlighted that ground movement has caused deterioration and cracking in sewers the vicinity of the cathedral, with the situation being carefully monitored by DALROD since. A more recent survey indicated that the sewers were now in need of relining, which is normally a straightforward procedure for the DALROD team. However, in this instance, one particular 225 mm (9 in) diameter sewer system, which was approximately 2.8 to 3.0 metres deep, had particularly difficult access problems. The access was tricky for various reasons including that the pipeline runs below a terrace of pre-war-built houses with no rodable access points
