Installing a concrete driveway requires a lot of planning and heavy labor. When well done the drive you will offer service for along time. Below is the process of installing a concrete driveway.
The most critical requirement of a good solid concrete driveway is the sub-base beneath. Too soft and wet soils make the bearing rock shift, leading to the failure of the concrete. If the substrate is dry or has had proper under drainage installed, placement of a leveling course of a suitable material is then required.
After the sub base is set, ensure the angles of the slopes are what you want on top of the concrete. Make sure the grade slopes away from buildings and do not cause any ponding areas and that all the captured water runs to the area you wish it to go.
Layout the finished driveway using your pins and string line. Set the string to the top elevation of the concrete for the driveway. Once all the string lines are in place, take a look at what you have created. Do the curved areas have neat and smooth lines? Are the square areas square? Are all the slopes correct? If not, make the adjustments. Now install your wood forms, making sure they can handle the pressure from the concrete.
Once that's done it's time to plan the concrete pours. If the driveway is large, pouring it all at once is not practical and you won't have time to properly install it. A sudden rain shower or broiling sun can cook the concrete or destroy the finished surface. Carefully watch the weather for the day of the pour. Concrete panels should not be poured larger than twenty or twenty-five feet in length and fifteen feet wide.
A joint expansion material is used after every panel to cater for the expansion and contraction. Sealing the joints prevent water entry to the slabs, controls any weed germination in warmer days and curbs ice forming that may crack the slabs when the climate is cold.
You can use reinforcing bars on the driveway to prevent ready-mix trucks from accessing the form.
A good concrete Driveway should be about 3000-pound to 4000 pounds to sustain more weight. Roadway edges should be double-reinforced with bars to block any chipping or cracking.
After the concrete is done, smoothing the surface is next. Power trowel gives a smooth surface which is not polished. Other people may prefer a broom to finish the surface.
If you intend to use colored concrete, all the concrete must be purchased from the same seller. Even if two suppliers use the same dyes, the same stone, and the same water supply, different sands will cause different shades in the finished product. Different brands of dye with the same color name will cause ugly shading in the finished product as well.
Making the right choice of a concrete contractor for your project is an important stage to help you achieve what you want. There are several key areas that you should focus on as a homeowner.
Years of Experience
A contractor like Concrete contractors Bellevue WA with at least five years of experience has been in the business long enough to know the dos and don'ts. The damage is minimal as they are less prone to mistakes. If you are unsure of something, they can guide you on the right path. No one wants a contractor that will end up damaging your property.
Proper Insurance and License
The right insurance coverage and licensing are of more importance than experience years. In case an accident occurs to a person or the property is damaged by the contractor, it will be safe for you. Consult with the insurance company to know whether their insurance is valid for the time they will be working for you.
Ask for at least five client references from the past two years. Past clients are often a good source for the concrete contractor's past work. You'll find out more information about them from a third-person point of view. A contractor with more positive references shows they are credible.
The type of service that a concrete contractor offers is very vital. Some contractors are of specific service others are general in their work. Note carefully what the contractor is specialized in and hire those who are in the line of your project. Those that perform concrete driveway installation should be highly experienced in it.
