Drainage Services Across Essex

Essex is dominated by London Clay, and that single fact explains most of the drainage faults we attend from Chelmsford and Colchester through to Basildon, Southend and the Thames-side towns.

London Clay is highly shrinkable. In dry summers it contracts and in wet winters it swells, and older clay drainage laid in it moves with the ground — joints open, pipes crack and sections drop out of line. The same soil makes soakaways ineffective, so surface-water systems that were undersized to begin with flood in storms. Coastal and estuary areas around Canvey, Southend and the Dengie are low-lying with a high water table and tide-locked outfalls, so infiltration and slow discharge compound the problem. Post-war new towns such as Basildon and Harlow have large shared private drainage networks now reaching sixty or seventy years old, including pitch-fibre pipework that deforms and collapses with age.

CCTV identifies whether we are dealing with clay movement, pitch-fibre failure or a simple blockage, and relining fixes most of it without digging up an Essex driveway.
