Tree roots growing in drains are a major cause of blockages in the UK. This week we were booked for a home buyers survey for a client in Hampshire. The client requested a tank empty and drain survey with a full report, line mapping and compliance check. The property has a soakaway with pitch fibre and spigot vitrified clay drains.
The survey identified that the drain system was in need of extensive repair, the drains were backing up due to severe roots ingress.
How do tree roots enter your drains?
Tree roots enter the drainage systems through cracks, fractures and at joints. Moisture in your drains attracts tree roots looking for a water source. A ‘tap root’ will grown along the drain pipe with smaller roots branching off to maximise moisture intake. Joints in older drainage systems are susceptible to root ingress as they offer little resistance. Once the drainage system has been compromised growth can develop to such an extent that flow is effected causing extensive problems.
How do you remove tree roots in drains?
This particular job required crown cutting – a method of clearing tree roots using a rotational tool to cut through the matter. Our engineer identified that downstream a new chamber was also required. In addition the gully had collapsed and needed replacing or re-rounding and lining. If there has been displacement to your drainage system your drains may need to be excavated and replaced.
Home Buyers Drain Survey
A home buyers survey reduces the need to excavate a drainage system and is an efficient way to locate and identify both simple and complex drainage problems that could develop into major issues in the future. Alton Pumps Services provide pre-purchase surveys to investigate potential issues and provides the buyer the opportunity to make a fully-informed decision before exchanging contracts.
