cwr Posted October 30, 2022 Share Posted October 30, 2022 Hi folks I was going to start spreading out a load of 63mm crusher run out the front of the house this aft, but wondering should I put a layer of membrane down first, eg something like a G90 woven geotextile membrane. We'll eventually put stone down on top of it. The ground had the top soil layer removed, and 100mm hardcore put down at the start of the build 2 years ago, buts it's muddy enough now. So concerned about mud making its way up through any new material put down. Link to comment Share on other sites More sharing options...
markc Posted October 30, 2022 Share Posted October 30, 2022 If you have hardcore with a bit of mud on top then the textile won’t be doing much but can’t hurt. You would be better scraping the mud off before stoning. Link to comment Share on other sites More sharing options...

Mr Punter Posted October 30, 2022 Share Posted October 30, 2022 The big rolls are good value - less than 50p/m2. I have seen some Terram equivalents from reputable suppliers so they may be worth a go. Link to comment Share on other sites More sharing options...
cwr Posted October 31, 2022 Author Share Posted October 31, 2022 It's mostly mud impregnated hardcore that's there at the mo, which is probably better than whatever lies below it? Plan is to put the textile on it, and then apply a layer of fresh clean crusher run, then the final stone. Another concern after seeing the amount of leaves on the ground in the past week, is whether after a few years these will end up increasing the organic content of the stones anyway.

That is one of the reasons we chose tarmac not stones. Link to comment Share on other sites More sharing options...
saveasteading Posted October 31, 2022 Share Posted October 31, 2022 The membrane's main function is to keep the mud below the stones, as they will otherwise mix. On that principle, and from experience, i have moved towards favouring non-woven fabric. I say put it down. It will pay itself easily. Link to comment Share on other sites More sharing options...
Happy Valley Posted October 31, 2022 Share Posted October 31, 2022 We are just looking into this now. Experienced tarmac local recommends Terram 1000 for under our tarmac driveway. Easymerchant is the cheapest I have found so far at £260 ex VAT for a 100m x 4.5m roll. https://www.easymerchant.co.uk/gravel-grids/terram-white-non-woven-100gsm-custom-size/ Link to comment Share on other sites More sharing options...
saveasteading Posted October 31, 2022 Share Posted October 31, 2022 For non specialist circumstances I have no hesitation in avoiding the big names. But for Terram that price is good. That is a big roll. Link to comment Share on other sites More sharing options...
Happy Valley Posted October 31, 2022 Share Posted October 31, 2022 My builders merchant is trying to flog me Multitrack 700 as an alternative to the Terram 1000 - it's £58 cheaper for a 100m roll. Not sure if it's a like for like product. Link to comment Share on other sites More sharing options...
saveasteading Posted October 31, 2022 Share Posted October 31, 2022 Either would be fine. Ask the BM why they favour one. It might be on better terms for them, or a more reliable supply....or something technical. Multitrack appears to be by a small uk company, which is a plus to me.

Multitrack has a puncture resistance of 1000N, Terram is somewhere around 14-1500N I think (ironic given it is Terram ‘1000’) but both are non woven geotex products so either would work.

Many online companies quote free anywhere, then only later say that this is GB mainland excluding Highland and half of Aberdeenshire. Appalling ignorance of the geography of the country, so I will always then find someone else. Link to comment Share on other sites More sharing options...
