Question 1

What is drain lining?

Accepted Answer

It is a repair without excavation where a new wall is created inside the existing pipe to make it watertight and strong, without replacing it.

Question 2

Does drain lining require excavation?

Accepted Answer

In most cases, no. We use existing access points (cleanouts, manholes). Sometimes, a small targeted opening may be necessary if no access is possible.

Question 3

What problems can drain lining solve?

Accepted Answer

Cracks, leaking joints, root infiltration, weakened pipes, porous or worn sections, and some sealing problems that cause recurring blockages.

Question 4

Can drain lining stop root intrusion?

Accepted Answer

Lining blocks root entry by making the pipe watertight and covering the joints/cracks. If roots are present, they are usually removed before lining.

Question 5

Does drain lining reduce pipe diameter?

Accepted Answer

Very slightly, as a layer is added inside. In practice, the surface becomes smoother, which often improves flow despite the small reduction.

Question 6

Is drain lining a durable solution?

Accepted Answer

Yes. The method is designed to strengthen the existing pipe. The process is controlled, and the condition of the pipe is confirmed before intervention with camera inspection.

Question 7

When is drain lining not suitable?

Accepted Answer

No. If the pipe is crushed, heavily sagging, completely collapsed, or with significant negative slope, the problematic section often needs to be repaired or replaced before (or instead of) lining.

Question 8

What is the purpose of a camera inspection?

Accepted Answer

A camera inspection allows viewing the pipe's condition, locating cracks/misaligned joints, and confirming if lining is possible and cost-effective.
