Drainage in Gravesham.

Gravesham's combined-sewer legacy is the defining characteristic for drainage work across DA11 and DA12. Rather than the separated foul-and-surface-water runs common on post-1970 estates, many Gravesend and Northfleet properties feed into a single combined system – a fact that must be established before any jetting or rodding work begins, because a high-pressure flush on a combined run can push debris toward a shared highway connection.

Every project starts with a CCTV push-rod or crawler survey to map pipe diameter, material, fall and connection point. Where scale or grease has reduced the bore, high-pressure water jetting clears the run and a follow-up camera pass confirms the result. Cracks, root intrusion and collapsed haunching – all common in the Victorian-era clay laterals found in central Gravesend – are addressed through no-dig CIPP lining where the host pipe retains enough structural integrity; open excavation is reserved for collapsed sections or where a connection to the combined-sewer main must be re-made. In Meopham's rural stock, private drainage runs and soakaway condition form part of the same survey scope. No callout fee applies; the fixed price follows the CCTV report. See /pricing.
