Common cctv drain surveys problems in Greenwich
- ✓ Pre-purchase surveys on Georgian townhouses around Greenwich Park and the Cutty Sark, where original drain runs are old
- ✓ Tidal groundwater checks for waterfront and Peninsula properties near the Thames Barrier
- ✓ Repeat blockage diagnosis on Victorian terraces in Woolwich and Charlton, where street tree roots often play a part
- ✓ Gradient-related faults on steep streets around Shooters Hill and Blackheath, where a change in fall speeds up silt build-up and joint wear
- ✓ Drain mapping for extensions in Kidbrooke and Plumstead, where new work sits beside older shared drains
