Most concrete trucks can hold between 11 and 15 cubic yards of concrete.

4-inches thick – covers 81 square feet. 5-inches thick – covers 65 square feet.

The capacity of concrete mixer trucks ranges from 3 cubic meters to as much as 16 cubic meters. Stirring volume: the amount of premixed concrete that the mixer can transport (after tamping the volume). It can be seen that concrete truck model of the concrete cube that can be discharged by the mixer truck.

There’s two scenarios, basically. The first is that the truck is immobile, but the drum will turn. In this case the driver will add almost all the water the truck is carrying and mix it with the concrete. This will retard the setting of the concrete, hopefully long enough to be towed somewhere he can spin out his load.

Can You Drive Concrete Trucks and Heavy Equipment on Concrete Driveways? Unless the concrete contractor that built the concrete driveway designed it to withstand loads heavier that regular passenger vehicles, the answer is NO. Even if the concrete does not crack immediately, there will be issues down the road.

Basically, 3000 psi is the flat slab of a home that has the dimension WxLxD (about 6″). This means that that slab of concrete will hold 3,000 lbs per square inch.

Using steel reinforcement will provide additional structural capacity for your driveway and is especially important if the slab will be exposed to heavy traffic. Use wire mesh for driveways that are 4 to 5 inches thick, and rebar for those that are 5 inches or more.

As for thickness, non-reinforced pavement four inches thick is standard for passenger car driveways. For heavier vehicles, a thickness of five inches is recommended. To eliminate standing water, the driveway should be sloped towards the street a minimum of one percent, or 1/8 inch per foot, for proper drainage.

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.

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.

Gravel for Concrete Ideally, 6 inches of crushed stone or gravel should be used for most driveways. Proper application requires that the driveway hole be dug out, and the soil has to be prepared.

What Type of Gravel To Put Under Concrete? The ideal type of gravel is ¾” to 1” washed and screened gravel.

Because concrete is a very porous material, it will absorb any moisture that it contacts. This can cause pooling. Without crushed stone, pooling water will settle under it and erode your slab. Adding a layer of crushed stone will add proper drainage, as well as create a barrier between your slab and the ground.

A concrete vapor barrier is any material that prevents moisture from entering a concrete slab. Vapor barriers are used because while fresh concrete is poured wet, it’s not supposed to stay that way. It needs to dry and then stay dry to avoid flooring problems. This is why a vapor barrier under concrete is essential.

Pour concrete over a solid, well-drained base of sand or gravel over clay and other poorly draining soils to provide even support.

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.

Epic Contributor. For soil cement the CRUSHED gravel should have poper mix of fines to larger pieces to make it as dense as possible. Add the proper amount of cement and water and mix well by some mechanical means, smooth to grade and pack it. The mix is not a slurry and is very hard to tell from damp gravel.

There are a few important things to keep in mind when completing a DIY install with pea gravel. Start with a heavy tamper to compress any soil underneath, add a sturdy base layer of either crushed rock or sand, layer on about 3 inches of pea gravel, and then tamp down again to make sure everything is compact.

RE: Pea gravel for interior floor slab support You could have 6- to 12-inch pea gravel or minus 3/8-inch pea gravel.

Geolift works for driveways, sidewalks, patios, garage floors, even pool decks. And yes, it is a foam, just like your beloved spray foam! Geolift works in three steps. The first step is to drill holes in the problem concrete.

Pea gravel is popular gravel for driveway aesthetics. It’s made up of round, small stones that can come in many different colors. This type of gravel will easily migrate and spread under the weight of vehicles, though, and needs to be stabilized for long-term, maintenance-free usage.

Crushed Concrete driveways are a much more cost-effective driveway solution compared to gravel driveways, regular concrete driveways, or asphalt driveways.

Project Summary

1. Stake out the path of the driveway.
2. Clear grass or topsoil from staked area.
3. Calculate cubic yardage of gravel needed for each driveway layer.
4. Schedule and prepare site for gravel delivery.
5. Level the ground along the path of the driveway.
6. Spread and compact the base layer of gravel.

Pea gravel

As compared to its counterparts, like the larger gravel, pea gravel is easy to walk on. It has rounded edges that do not cause any discomfort even if you walk bare feet on it.

Because of its size, texture, and color, pea gravel is typically used for more above-ground projects and applications. Like crushed stone, pea gravel can also be used for underground projects, such as drainage and pipe bedding. It’s also a good choice when looking for fence post installation aggregate.
