Drainage under block paving

[Gary Prentice]

 

It sounds like the job was bodged in the first place. my thought, but outside my field

 

You might be lucky if you can get someone in to "drain jet' it, which could solve the problem until you wind up the jacks on your caravan:biggrin:.

 

As said above land drains under block paving is a bad idea. It sounds like a dig-up job, then lay rigid pipe down to the drain/sewer.

 

A root cutter won't help in this instance, it will shatter/break/crack the land drain

 

I wondered if they were only suitable for clay only. [/]Do they work in the new 'plastic' pipes, the thick ones?.

 

This has all been very educational:thumbup1:
