Drainage Services in Bexley

Bexley spans ground from the Thames floodplain around Erith and Crayford, where a high water table and historic marshland mean surface water drainage needs particular care, up to higher gravel and clay terrain around Sidcup and Bexleyheath. Riverside areas often have older combined sewers that can be affected by both heavy rain and periodic high river or groundwater levels, occasionally requiring pumped drainage for the lowest-lying properties.

Sidcup and Welling, developed largely through the inter-war period, have extensive clay pipe drainage serving semi-detached suburban housing, with mature garden trees a recurring cause of root ingress. Old Bexley retains some older Victorian drainage in its historic core, while more recent development on the borough's edges generally uses separated plastic drainage systems that perform more predictably.

We approach Bexley drainage work with a CCTV survey that identifies pipe age and material, and checks for groundwater or river influence in the lower-lying riverside areas. High-pressure jetting clears root and silt blockages common in the borough's inter-war clay pipework, and no-dig lining allows repairs without major excavation, which is particularly useful on the flood-prone ground near Erith and Crayford where the water table sits close to the surface.
