Is thicker concrete less likely to crack?
by thicking up the slab you are creating more resistance to bending by load factors so less cracking.
adding more cement increase the psi and its more resistance to bending by load factors, less cracking..
What is the best base for concrete?
The base course material, according to ACI 302, “Concrete Floor and Slab Construction,” should be “compactible, easy to trim, granular fill that will remain stable and support construction traffic.” ACI 302 recommends material with 10 to 30% fines (passing the No. 100 sieve) with no clay, silt, or organic materials.
Will a 4 post lift fit in my garage?
If you can park your vehicle in the garage then you have enough floor space for a car lift. Your garage ceiling needs a minimum height of approximately 10 feet. … In most cases, we can tell you over the phone if you can fit a car lift in your garage.
How thick should concrete be for a 2 post lift?
The minimum and recommended thicknesses of concrete slab for car hoists. Garage Equipment’s two and four post hoists require a minimum of 100mm (about 4”) of reinforced concrete slab to be safely installed.
What kind of stone goes under concrete?
Backfill beneath concrete flat-work along foundation walls should be accomplished with a granular material that is uniform in size. Some fill materials, such as round stones like pea gravel, tend to be self compacting. “I recommend open-graded granular material be used,” says Tull.
Should you put plastic under concrete?
The sand layer cannot dry downwards by vapor diffusion because of the plastic sheet—it is a vapor barrier after all. In fact that’s why we have it under the slab. We want a vapor barrier under the slab. ** We want to prevent water vapor from coming up from the ground into the concrete slab.
Is sand a good base for concrete?
Pour concrete over a solid, well-drained base of sand or gravel over clay and other poorly draining soils to provide even support.
Is wire mesh better than rebar?
Considering the support constraint, rebar is undoubtedly stronger than wire mesh. Several constructors consider rebar for domestic jobs. For thicker driveways and locations that involve greater traffic, rebar is always a good option to consider.
Can you pour concrete over dirt?
Long story short, yes you can pour concrete over dirt.
How big of a garage do I need for a lift?
A car lift will optimize any space, so don’t fret if you’re concerned that your garage is too small. The car lift itself will fit into one bay space and it is optimal to have 11-12 feet clearance height. Garage Living also has modified garage doors to accommodate the lift.
Do you need rebar for 4 inch slab?
No, you do not need rebar for a 4-inch slab of concrete on grade. A 4-inch-thick slab cast on the ground and in permanent contact with it will float and rebar is not required. Rebar is recommended on concrete measuring 5 – 6 inches thick.
What is 6000 psi concrete used for?
For new concrete construction projects, concrete overlays and concrete repairs. Use to construct footings, sidewalks, slabs, steps and patios, setting deck posts, fence posts or poles.
Can I pour a 2 inch concrete slab?
If done properly, new concrete can often be poured right over an existing slab. For this to be feasible, the contractor needs to pour at least 2 inches thick, use smaller aggregate, and incorporate reinforcement such as welded wire mesh or fiber mixed into the concrete.
Can you pour concrete over old cracked concrete?
If the existing concrete is in good shape structurally, you can pour new concrete over it to freshen it up. Worn or cracking concrete makes your outdoor areas look drab, outdated and in need of fresh concrete. … If the existing concrete is in good shape structurally, you can pour new concrete over it to freshen it up.
Can I install a lift in my garage?
Most lifts do not add significantly to the weight on the garage floor, making them acceptable for installation in standard residential construction garage floors.
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. However, not every piece of concrete necessarily requires that extra boost.
Do you need rebar for 6 inch slab?
Rebar is recommended for concrete that measures 5-6 inches in depth. The type of and intended use of concrete impacts the need for rebar reinforcement. Rebar must be placed at the center of or slightly above the center of the concrete slab—hence why it should be a certain thickness for best results.
Is gravel necessary 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.
