I'm about to convert an integral garage from my 1993 build detached house.
there is a tarmac drive leading up to the garage door.
Although I'll be contracting the job out, I want to have a good understanding of the work required, and I have a couple of questions:
1. The "trial dig" to establish what foundation lies beneath existing garage door in order to support new bricks/window - is it normal to dig away the tarmac in front of the garage door to find the foundation, or to do it by smashing through the garage concrete floor on the inside and looking from the inside so as not to damage the tarmac?
2. Building regs, insulation etc in regards to flooring - what's the best way to tackle the flooring, is it normal to dig out the existing garage concrete floor? I'm particularly keen to make sure I understand this bit, especially in order to get the best thermal efficiency - what's the "best" way to approach it, how many layers are there to a proper floor, and what should they be made of? where do "thermal breaks" etc need to be placed?
Thanks
Alan
