2 questions for the wise ones out there?
New road going in for a residential house - acquired about 500 m3 of chalk, best quality I have seen for a while. Planning on using it for a base followed by a few inches of road Plainings whacked down hard ready for a tarmac cap in the future. Will chalk @ maybe 300mm be enough / work at all? It's a substitute for hard core which is getting expensive!
Secondly, re concreting yards, 8 inch with re bar. I know I need to put expansion joints in, thinking ever 6 m. Current plan is to pour every other then when it sets fill in the others. Question is I think you can buy expansion kits, otherwise it's cut out and fill with mastic / resin. What would people recommend?
