Localised Structure Repair

What is Localised Structure Repair (LSR)?

Where traditional drain excavation is difficult, Localised Structure Repair (LSR), sometimes known as drain patching, can be applied. This is similar to drain relining, however, this is where a certain area of the drain is relined, rather than the entire pipe. It tends to be used in areas where traditional drain excavation is difficult or is awkward to get to. LSR is used for smaller cracks and breaks in pipework where a full structural relining job may not be necessary.

It is a method of rehabilitating blistered pitch fibre or crushed pipework. Remedial work can include re-forming the pipe if necessary and then installing the patch liner.

We tend to work with pipework with a diameter of 100mm to 450mm and a length of 1 metre. If the damaged pipework has a wider diameter and longer length than this, you may want to consider drain relining.

We offer this service throughout Kent and London.

What is the difference between drain relining, drain patching and LSR?

When do you need LSR?

If you do not want the disruption that is caused from drain excavation, are looking for a cheaper alternative and have damage on a drain that has a diameter of 100mm to 450mm then LSR is for you!
