Good evening, I'm looking for a little help in tracking down a specific product that will improve the headroom in my basement conversion. I've had the OK from Building Control to use Jabcore 70 Hardcore replacement under my concrete slab which will provide acceptable U value and negates the need for 150ml of hardcore base. Sounds fantastic- but I can't find a stockist. Anyone know of it or a similar alternative that is available then please let me know. Thanks in anticipation Cratchett Hardcore-Replacement.pdf
