how much does a new driveway cost

It is not a good idea to pay more than 20% upfront. Once the project has been completed satisfactorily, the balance is due.

To protect exterior concrete slabs from freeze-thaw conditions, you should use a high-quality sealer. The sealer protects concrete from moisture absorption as well chemical and grease stains. A sealer will enhance the color of decorative colored concrete.
There are two types of sealers that can be used for exterior concrete. They are film-formers (or penetrants). Penetrating sealers are the most effective in protecting against moisture absorption. No matter the type of sealer that you choose, it is important to follow the manufacturer’s instructions.
It is unreasonable to expect your contractor or subcontractor to match the concrete driveway's color to a concrete sample, a neighbor’s decorative concrete driveway, or an image from a brochure. Even plain concrete can display color variations. This happens especially if there are multiple concrete loads or concrete placements on different days. These color variations are very minor and will fade over the course of time.
You can expect to pay $6 per square ft for basic stamped cement, or $15 for multi-pattern designs with unique coloring effects. Although stamped concrete can be more expensive than asphalt for the same reason, you'll see a much higher return on investment. Concrete driveways are more durable than asphalt, require less maintenance, and can add curb appeal to increase your home's value.

Placing concrete is another aspect of the job of a concrete contractor. Concrete is poured into forms. The team uses rakes to move the concrete through these forms.
After concrete is poured, it must be consolidated and compacted in order to prevent air pockets. A broom finish can be applied to the concrete. This is done by pulling a special bristle brush over the surface in order to achieve a rough texture. Finishing may also include adding decorative elements, such as design, dye, or any other details to concrete.
Concrete means that concrete is used in stages. Also, each phase or step is vital as they all impact the final output. To create a client-friendly output, it is vital to monitor every stage of the work. With project management software, contractors can keep track of progress using pictures and other data. These data can be sent to and accessed through the software at any time. It can be inspected that the crew is adhering to the project's timeline. This helps avoid mistakes that may lead to future unwelcome costs.
To be a concrete contractors, you need a bachelor's level in civil engineering, or a similar degree in a related field. In addition to this, you should also be licensed as a concrete contractor.
Experience is another requirement for being a concrete contractor. It is possible to study all the theories of concrete construction. However, without sufficient experience, these theories won't apply to the job. The job requires that one has experience with the techniques and other parts of it in the field. Training is available to help you achieve this.

Always ask for references from the contractor before you sign any contract. Then, contact them to find out more about them and their operations. Ask questions about the type of project, length, communication, involvement and overall opinion of the references. This information will help you make your final choice.
