For concreters, good finishing techniques will make a concrete surface look great for a while, but it is more important to have appropriate ground prep since that can help boost the strength and stability of the surface for years to come.
Here are some reasons why proper prep is essential to any concreting project.
Prep for Crack-Free Concrete
A concrete driveway can last for decades if it’s installed properly. So, a good base is everything because concrete may crumble if not poured on a stable and solid base. This means that a concrete driveway will depend on the condition of the existing soil, climate, and where you plan to park your car.
It is not recommended to pour directly over gravelly or sandy soil without setting the base. However, if you live in an area with a cold climate, you will need to pour organic soil and heavy clay into the area where heavy vehicles will park. A rule of thumb is to increase the base layer on that area to about 10 or 12 inches deep.
How to determine the base you need?
The best way to know the ideal base for your concrete surface is to get in touch with a concreting company or service provider near you. They can check and explain your soil conditions and the type of base to use in your project. A qualified concreter can also recommend the proper base depth according to the guidelines of your suburb.
Also, when you are laying the concrete on the base, you will need to balance the amount of water in your concrete mix because this can affect the stability of the slab. There is an ideal water-to-cement ratio that can produce the best results.
Another important thing to do is reduce wind exposure on your concrete base because that can lead to quick drying. Therefore, you will need to block the surface with barriers or use anti-evaporation products to ensure that the base doesn’t come off quickly. This will ensure that you prevent the surface from cracking.
Appropriate curing of the base
It will take 20 days before concrete is adequately cured, so the first seven days after pouring is crucial. You will need to use a biding agent that can retain moisture on the surface since that will ensure that your base will gain strength.
You must also spray water every few hours a day for at least seven to ten days because this process will make it more durable. Once the concrete has cured, it will no longer be affected by pressure or extreme temperature.
