Not at all about you Shaun dont take it personally..... just the thoughtless crap they are selling with no regard for the environment...... of course concrete has it issues but that doesn't mean it makes that pipe o.k.I am still at a bit of a loss to see why this land drain has caused such a stir!!
There must be more damage being done with concrete than just my 30m of poly beads!! I use a lot of recycled agg in roads and drives but the problem here was access. It serves a purpose. Is the issue just future contamination or use of plastic in general??
Future contamination imho
