For a proper lift installation, begin by evaluating your concrete area and its existing specifications. This begins by inspecting your concrete slab to make sure it’s an adequate 4.25” thickness or more, has cured at least 28 days, and the surface has no more than a 3-degree slope.
How thick should concrete be for auto lift?
That’s the minimum – however if you’re installing a new slab, it’s a great idea to plan around a slightly deeper concrete for even better strength – a least 6 inches thickness concrete is our recommendation.
HOW MUCH CAN 4 inches of concrete hold?
Typically we like to limit the weight to about 40 lb/sqft on an unknown 4″ slab. In most cases you can go to 80 lb/sqft in isolated spots, but unless you know roughly what the soil bearing and reinforcing is for that slab you might be looking at cracking.
How tall does a garage need to be for a 2 post lift?
If you want to install a typical 2-post or 4-post lift in your garage, you need a ceiling that’s higher than 11 feet. While you can get a 2- or 4-post lift that works with a lower ceiling, almost all these lifts are not ANSI certified.
Do you need rebar for 4 inch slab?
The thickness of rebar should be no more than 1/8 that of the slab, so a 4” slab shouldn’t have steel greater than #4 or 1/2″ bar. It’s best to check with a Structural Engineer if your slab will bridge or cantilever. What is this? For 4” concrete slabs used for driveways and patios, #3 rebar is common.
What is 3000 psi concrete used for?
3,000 PSI. The residential workhorse of concrete, 3,000 PSI can be used for driveways, patios and sidewalks. Its durability will help shrug off the freeze-thaw cycle of harsh winters. This is a fine choice for any general construction use.
How much space do I need for a car lift?
As a guideline, count six feet for space underneath, five to six feet for vehicle height and one foot of clearance. That means you need a minimum of 12 feet of ceiling height to comfortably install and work with your auto lift.
Can you put a car lift outside?
An Outdoor Car Lift. Technically, the correct answer is, “You can put it outside (as in, who’s stopping you?), but should you?” Lifts are designed for indoor use, installed in a temperature-controlled environment.
How tall does a shop need to be for a lift?
Typically, a 12-foot minimum clearance, floor to ceiling, is required for your general two-post lift. Higher ceiling height is required for some of the four-post storage lifts and anything designed for larger trucks. For personal or hobby shops, many people purchase or reference Behm Design plans.
How thick does concrete need to be to not crack?
To prevent load-stress cracking, make sure a slab is built over a uniformly compacted, well-drained subgrade, and is thick enough to withstand the kind of use it will get. In residential concrete, 4 inches is the minimum thickness for walkways and patios.
How many yards of concrete do I need for a 24×24 slab?
For example, for a concrete slab that is 24′ X 24′ X 4”, simply enter 4 in the Thickness/Depth field, 24 in the Width field, and 24 in the Length field. Click “Calculate”. Your answer should be 7.11 yards. Note: The Concrete Volume Calculator can also be used to determine yardage for aggregate products.
How strong is 6 inches of concrete?
Determine the Pad’s Thickness For example, a 6-inch pad with a compression strength of 700 psi can support 1,105 psi. If it was 7 inches thick, it could support 1,194 psi, and if it was 12-inches thick, it could support 1,563 psi.
Which is better 2 post or 4 post lift?
A four post lift takes up much more room than a two post lift. A two post lift will raise a car “higher” in a low ceiling garage. If you have a 10 foot ceiling, the two post lift will raise most vehicles to about 6 feet off the ground. A four post lift makes it much easier to load and position the vehicle.
What is the standard garage height?
Standard Garage Height Not counting the attic, bonus room, or apartment above garages, the typical height for a garage comes in at 7 feet at a minimum and usually 8 feet. Those with vaulted ceilings still come in at the 7 to 8 feet range before the pitch of the roof starts turning inward.
What is the size of an average two car garage?
An average size two car garage space usually ranges from 9-14 feet wide by 18-22 feet long (to get sq. ft. multiply width by length).
Do you need gravel under concrete?
Whether you pour concrete for a walkway or patio, a strong gravel base is required to prevent the concrete from cracking and shifting. Gravel is especially important in clay soil because it doesn’t drain well, which results in water pooling under the concrete slab and slowly eroding the soil as it finally drains.
Which is better rebar or wire mesh?
In summary, rebar vs wire mesh can have costly differences. Rebar remains stronger and ensures consistent contact in the soil where as wire mesh is unpredictable and often results in a week concrete foundation.
Do you need wire mesh for 4 inch slab?
No, they do not. Larger projects or slabs may need steel reinforcement to provide support or extra strength. Wired mesh can also help resist cracking.
