Local context

Drainage in Portsmouth: what we expect on site.

Drainage in Portsmouth comes down to access and water table. The island's classic terraces share back-alley runs serving a whole row, with rear inspection chambers that are frequently buried, paved over or built upon – so the first job is finding and proving the run on CCTV before anyone lifts a slab. The high water table means a cracked lateral takes in ground water as well as backing up, which we confirm on camera and address with no-dig relining wherever the pipe allows. On shared runs we map responsibility and access so the right length is repaired. Surveys are reported in writing, and relining or excavation is fixed-priced after the camera survey, with no callout fee – see /pricing.
