You can also use a lawn mower to mow the area, but be careful not to over-mow, as this can damage the soil underneath. Once you’ve removed the dirt and soil, it’s a good idea to cover the hole with a tarp or some other type of cover to keep the weeds from growing back in.

You can put new concrete over old concrete. If not taken care of, unresolved issues with your old concrete, such as cracks or frost heaves, will carry over to your new concrete. You have to pour it at least 2 inches deeper than the existing concrete to prevent water from entering. The amount of concrete you need depends on the size of your home.

For example, if you have a 1,000 square foot home, then you will need about 2,500 square feet of new cement. If you are building a larger home with a lot more square footage, like a 4,200-square-foot home or a 5,600-sq-ft house, your concrete needs will be much higher. You will also want to consider the type of home you’re building, as well as the number of bedrooms, bathrooms, and other amenities you’ll need.

Can you pour concrete without gravel?

Yes, you can pour concrete over dirt. If you have a soil type that is very compact, such as solid clay, you may be able to support a layer of concrete, but not so compact as to allow the concrete to be poured over the top of the soil.

In this case, it may be necessary to add a small amount of sand or pebbles to the bottom of your concrete layer.

If your soil is not compact enough, or if you are using a soil that has a lot of organic matter in it (e.g., peat moss), then it is possible that you will not be able to create a solid base for concrete.

You will need to use a mixture of cement and water to fill in the gaps between the layers of soil, and then add more cement or water until you reach the desired level of compactness.

What happens to soil under concrete?

Whether it’s a foundation, driveway, patio or pool deck, soil erosion is one of the main threats to the concrete slab.

If you don’t have a concrete mixer, you can mix your own concrete by mixing 1/2 cup of concrete with 1 cup water in a 1-gallon bucket. You can also buy pre-mixed concrete at your local home improvement store.

Can I pour concrete over 2 days?

About two hours maximum is how long you have until you have taken into account other considerations. It is way beyond ‘begun’ to set after that. If you knew it was going to be a long time before you could get it back in place, your previous pour should have left some rebar sticking out.

If you don’t have access to a drill press, you can use a hand drill to make a small hole in the side of the container. This will allow you to drill a hole through the bottom of your container and into the concrete. You can then use the hole as a guide for drilling the next hole, and so on.

It’s a bit of a pain to do, but it will save you a lot of time and frustration later.
