Southgate housing, from a drainage engineer's side
Southgate offers a blend of substantial interwar properties and later 20th-century developments, including some apartment blocks. Drainage systems reflect this evolution, with older clay drains alongside modern PVC. The area is well-established with deep-rooted tree cover along streets and in gardens. There is a significant proportion of high-value residential transactions and commercial premises, demanding robust due diligence.

What fails here
Common drainage problems in Southgate
01
High-Value Property Transaction Surveys
For the higher-value homes in Southgate, drainage due diligence is a non-negotiable part of the conveyancing process. Our reports go beyond basic functionality, assessing the remaining asset life of the drainage system and forecasting major capital expenditure, which can influence purchase negotiations.
02
Drainage Design Verification for Extensions
Many properties undergo significant renovation and extension. Our surveys are used to verify the adequacy of existing drainage capacity and the correct installation of new connections. This documented verification is often required by building control and for architect/engineer sign-off.
03
Surcharging from Inadequate Capacity
Older clay drains, particularly those serving extended properties, may have insufficient capacity for modern water usage, leading to frequent surcharging (back-up). CCTV inspection confirms the pipe diameter and flow characteristics, providing technical evidence to justify system upgrade or separation.
04
Lateral Connection Defects
The point where a property's drain connects to the main sewer is a common failure point, suffering from poor original workmanship or ground settlement. Our engineers use CCTV to meticulously inspect these junctions, classifying defects like open joints or fractures that lead to leaks and ground subsidence risk.

Blasts grease, silt and root growth from pipe walls without digging.
