hi - ive a 35m2 cellar that i'm waterproofing with system platon. floor is wet clay/aggregate, level with base of foundations (the toe-in brick), so i need to sort a concrete floor asap - the platon goes over the top of this. headroom is at a premium so want advice on best approach - building regs apparently requires 100mm concrete (min) laid over (?mm) compacted stone. thx
