Protection Against Roots

[MortarThePoint]

I'm about to lay lots of 110mm drainage pipe and wondered if there is some effective protection I can put in to prevent root penetrating the ring seals. Ideally it would be something I can wrap around the joint. Has anyone identified a good approach.

 

Osma have something new called Rootseal. No idea if it works and it is only on newly bought Osma fittings and I have a lot of older black ring fittings.

They only find the joints if it leaks surely? Just make a good job you should be fine.

That's the plan, but you never know

I can find geotextile sleeves designed to stop silt and sand entering land drain pipes, but not one designed to sleeve over pipe couplings to stop root penetration.

 

Three approaches I am considering are:

1. Do nothing
2. Wrap and cable tie each coupling with a 1m length of non-woven geotextile like this: https://www.amazon.co.uk/dp/B0DQ88WHD4/?th=1
3. Use a 1m length 8" temporary downpipe or layflat tubing an duct tape at each coupling (normal 150mm not large enough)

Actually, the socket OD of the couplers is just too big for 8" layflat tubing so would need to be 10" or larger: https://www.amazon.co.uk/Triplast-LF5001001-10-Inch-Layflat-Tubing/dp/B07BRNYC32/
