MortarThePoint Posted May 12, 2020 Share Posted May 12, 2020 We're going to be pouring the raft for our garage/workshop in a couple of weeks. It's a real treat for me to have this space and part of the reason why we are doing the whole selfbuild thing. It's my last chance to think of some of the details to add and I thought I would ask people to fantasise a bit. They can be simple details (e.g. I am thinking of asking them to cast in anchors near the door pillars for pulley winches) to that 'if only I could' thing (e.g. I'd love a car lift but that's not on the list unfortunately).

Miek Posted May 12, 2020 Share Posted May 12, 2020 Power float the floor flat so you can roll a jack around easily. I did this and it's great. Very easy to sweep up too. Link to comment Share on other sites More sharing options...

Sink with hot and cold water, maybe even a loo! Floor drain may be a good one as well. Link to comment Share on other sites More sharing options...

Just some time spent with a bull float will do that as well. Link to comment Share on other sites More sharing options...

Just right to sit in on a duck board to do an oil change, about the only thing it gets used for. Anything deeper and you are into serious retaining wall stuff.

BotusBuild Posted May 12, 2020 Share Posted May 12, 2020 My garage design requirement has a four post lift included - I own a classic and do a lot of the work myself (much to the annoyance, but praise and admiration, of the local specialist garage) so it will be used for working on the car and also storing it raised with drip trays installed and the daily drive will be parked underneath.

joe90 Posted May 12, 2020 Share Posted May 12, 2020 I have a sink and toilet (old kitchen units), great to get the oil off yours hands before going indoors. I also have a classic and dreamed of a two post lift but dreams eh,! Link to comment Share on other sites More sharing options...
MortarThePoint Posted May 12, 2020 Author Share Posted May 12, 2020 We're going for hot water sink and a loo. I don't fancy being repeatedly told off for traipsing filth in to the new house ? 49 minutes ago, ProDave said: Yes mine is only 1 metre deep. Just right to sit in on a duck board to do an oil change, about the only thing it gets used for. Anything deeper and you are into serious retaining wall stuff. A shallow pit is a good call. Combined with a low lift and you've got most of the win of full lift. There might be a call to the Structural Engineer coming up. That said, I think I remember reading somewhere that pits aren't allowed any more due to fume buildup. Is that beyond a certain depth or something?

joe90 Posted May 12, 2020 Share Posted May 12, 2020 I installed an electric over sink water heater, not really hot but warm enough for washing hands (in winter). Link to comment Share on other sites More sharing options...

dnb Posted May 16, 2020 Share Posted May 16, 2020 3 phase power. Everyone needs good machine tools. Make it bigger. The correct number of classic cars to own is always N+1, where N is the number currently owned. Get the floor very flat so you can do suspension geometry measurements easily (seeing as you aren't having the 2 post lift) Overhead gantry for the winch for that time you need to get an engine out of a TVR, and the wheeled engine hoist doesn't have the reach. (Don't ask how I know...) Sink with hot water is a good call. I think a reasonable 2 post lift is going to be cheaper than a pit. But it depends on your soil etc of course.

Underneath that it's MOT Type 1 for about a metre down to the stiff clay Edited May 16, 2020 by MortarThePoint Link to comment Share on other sites More sharing options...

They were briefed that I wanted a 2 post lift. Not got as far as building the workshop though, so I've not had the "design review" yet where I sign off the floor design.

A quick Google turned up a bloke from the US saying 3000PSI @ 4 inches. 3000PSI > 21,000 kN/m2 so that doesn't make sense [Edit: that's the tensile strength of the concrete not the floor loading] Edited May 16, 2020 by MortarThePoint Link to comment Share on other sites More sharing options...

I've been wondering if you can get a ~10mm thick neoprene mat with built in electric heating elements. Then you can lay it where you need it and it saves tools and elbows from hits on the floor Link to comment Share on other sites More sharing options...

MortarThePoint Posted May 16, 2020 Author Share Posted May 16, 2020 In theory a 2t car would need 2m2 per side so thats about 1.5m square on each side. The limiting factor is likely to be the GreenGuard GG300 insulation under the concrete Link to comment Share on other sites More sharing options...

Good point, I'll ask what the spec is for localised loads as it obviously does allow cars to be parked in there Link to comment Share on other sites More sharing options...

How about a dual function megnetic system that could also levitate a car for an oil change. Lifts and pits are 20th century thinking. Link to comment Share on other sites More sharing options...
