How Level is Your Shop Floor?

[Gary Curtis]

Mine isn't. It has a pronounced slope. The slab was poured 14 months ago, and my table saw arrived a year ago. I was bothered by the tilt as I worked away with a 48" carpenter's level and misc. bubble levels to get the tables dead flat and dead even.

Does it matter that the best I could do was shoot for an equal bubble deflection on all the table surfaces?

Hi Gary,
How much slope are you dealing with?

Mine was both sloped and a glacial mountain range when I moved in ... the slope didn't bother me nearly as much as the protruding pieces of concrete. In 16 feet, it dropped 6 full inches, but the peaks of some of the chunks stuck up only about 3-4 inches.

I finally laid down sleepers in a 12x12 inch grid and put down some cheap stuff - at the time it was particle board. Then I painted the whole floor with garage floor paint. Now the floor's perfectly level and has no surprise bumps to trip over. It was a good move, since I bought a ton (literally) more machinery that really needed to be level and on a smooth surface to move around.

Mine isn't level at all. Double garage, pronounced hump in the middle of the floor.

My previous shop was actaully worse, so the table saw sits on a platform with four of LV's "one ton" glides supporting the saw. Works great.

Ladders and sawhorses have to be placed carefully to avoid wobbling.

Concrete guys do concrete because they don't how how to read a level, square, or tape mesure. Which by the way are the three most basic carpentry skills.

If you wanted a spot to be dead level for some reason, you could put down a layer of a self leveling grout, of course checking it with a level as you go, to flatten out and level the floor.

I build a lot of large pieces on the floor and rely on it being level. Beds , chairs , cabinets are often layed out...modified and components cut and measured from the shop floor....it really needs to be dead on!

Mine is pretty level. Only a few inches from one end to the other but it needs to slope a little for drainage unless you have a drain in the center and then it would slope toward the drain. If you want it flat and level your gonna have to build it.
My tablesaws are resting on 3 points. It is the easyest way to level them. I learned hanging mirror in yatchs, nothing is square or flat, that you will always have 3 points that will touch a surface. you have to shim the 4th.
As far as assemly just build you a table, mine is 24" tall, flat on top and put ajustors on the legs to ajust it to the floor. For me that is a good working highth and lets me work all the way around something. If you really want to get funky put one on a lazy susan so you can turn it to do the finish work. That is a project I will be working on in the future

Garages are not supposed to have flat floors. They are supposed to slope down toward the door so that water and ice drain out instead of pooling inside the building.

Hey Gary,
Our shop floor is slightly sloped for just that reason, drain off any water out the garage door. But we've not had any trouble at all leveling the band saw, lathes. Seem to be just fine. Best of luck to you on your endeavors, though. Jude

Level? What is this strange term you speak of?

I use lots of shims.

[Rob Will]

My machine room was poured dead level. Other parts of the building have floor drainage either to a drain or out the overhead doors.

[Larry Fox]

Not at all. Shims under almost everything. My Uni has the 4th corner shimmed with a short piece or Romex that was lying around when I initially setup - I will replace it ..... one of these days.

[Cliff Rohrabacher]

My shop has a little slope a couple degrees t so that when the thing floods the water all runs out down the hill.

I have used this feature on numerous occasions to clean the whole shop and basement.

[Steve Schoene]

Building codes require garages to have that slope toward either drain or doorway. The one on the house I am having built was poured this morning and is being finished as we speak. It will slope 2" in 23 ft.

Of course, it won't really see cars, since it really will be my shop.

My shop has a wooden floor which over time has developed high and low spots. When I roll around the saw, the mobile base would bow with the floor which would force my laminated extension table out of square. To help with the problem, I made my own legs for the extension table angled back to the base of the cabinet. Reducing the size of the footprint necessary for the mobile base, helped maintain the alignment of the table to the saw top.
