Hi all, I'm looking to split my integral garage in half to have a utility room for the wife. I am unsure what to do with the concrete garage floor as there is only a 90mm difference between that and the kitchen floor. I did think about building a timber floor. Any thoughts or ideas would be appreciated, cheers
I'm not sure if there's any dp under concrete slab so I was going to insulate it and put in new membrane. I've just looked on kingspan website about doin a floating floor.
Is there a internal door from the kitchen to the garage, if so 90mm is to shallow for building control purposes. Not that it matters if your splitting the garage in half, so DPM, 70mm celotex and 18mm t&g chipboard flooring would be close enough for a utility room.
Hi Phil, there is a door from kitchen into garage, can I ask what you mean about 90mm been to shallow for building control? Cheers
I understand they don't allow 'single' steps of that size (or any?) - a trip hazard. In any case, you surely want some insulation down there? In which case what Phil suggests sounds ideal. Job jobbied. (Do make sure the garage floor is level, tho' - they sometimes slope...)
Phil will probably give you more accurate info, but I believe you need a garage floor to be about 20 cm lower than an internal floor in case of a fuel fire.
Garage floors should be 150mm below the house floor if there's an internal door, its all to do with fuel spillage/ flooding and it getting into the occupied section of the house.
Should that have been picked up on survey when we brought the house? I think the extension was built around 20yrs ago?
Hardly an earth-shattering issue... In any case, I'd have thought that the 'step' should now be betwixt the new utility room and the remainder of the garage? Personally, I'd have the utility room at the same height as the adjoining kitchen - anything else is chust plain daft. Especially as the addition of insulation and a solid chipboard floor will do the job of levelling it all out nicely.
