Hi I'm going to do a garage conversion in the near future and would like to use a suspended wooden floor over the original concrete garage floor which is not been DPC membraned. The span of joists from wall to wall is 3010mm but the house floor is only 240mm above the garage floor. The garage floor is one brick below DPC and the concrete is only around 3" thick over packed dolomite so I don't know if I can use sleeper walls without digging up the concrete and putting in deeper founds. Is there any easy way to do this or have I to resort to putting in a new concrete floor? Cheers for any info g
