What are the Basics Regarding Concrete Driveways?

should have the strength of 4,000 pounds for each square inch. This should have air entertainment value of 6 percent where there are very cold winters. Air entrainment creates bubbles, which facilitates water in the concrete area to see when it freezes. The aggregate of the concrete should be 0.75 to 1 inch. However, smaller pieces should be considered. In order for the installation to be easier, the slump rating of 4-5 inches should be good.

Concrete driveways are good as they are low maintenance, permanent, and they improve the appearance of the home. This decreases the erosion and helps to keep the place clean.

Here are Some Other Factors to Consider with regards Concrete Driveways and They are:

#1. The subgrade needs to be prepared properly. It should be uniform in compaction as well as in the composition of the soil. This will ensure that there is adequate support and the thickness of the slab will be even. This will also prevent the slab from settling and cracking.

#2. If there are soft spots these should be removed and it should be replaced using good material like crushed rock or gravel.

#3. The concrete should not be placed on subgrade which is bone dry, but it should be water sprayed first so that it is dampened. That will prevent water from getting wicked from the concrete.

#4. In order to prevent random cracking, control joints should be put in the space of 10 feet for a slab that is 4 inches thick. These random cracks do not lower the service life, but they are unsightly in appearance. Joint patterns should be avoided which produce triangular sections or rectangular sections. The control joints should be ¼ of the thickness of the slab. There should also be isolation joints, which need to be installed when the sidewalk is met by the driveway or where it meets pavements or the garage floor slab.

#5. Steel reinforcements are used for giving additional capacity for the driveway and it is needed if there is to be heavy traffic. This will not prevent cracks but is needed to hold the slabs together in case cracks happen. Reinforcements are in wire mesh form or grid patterns.

#6. The thickness of the concrete should be a minimum of 4 inches but by adding an additional inch, 50% of the load capacity can be increased.

#7. Finishing is done by leveling the concrete, floating it with wood or a bull float of magnesium, adding a broom finish so that traction can be improved or using stamping or other kinds of textured finishes.

#8. The driveway should be sloped away from the structure and towards the street at a slope of around 1/8 inch.

#9. Curing is needed when finishing is done. This helps increase the resistance to the various elements.


There are different kinds of material for installing on driveways. Gravel is the cheapest, brick is the most expensive but concrete and asphalt are those that are common.

The difference is that concrete is longer lasting but more expensive to install than asphalt. Asphalt, however, needs more maintenance but it is simpler to repair. Concrete, however, can suffer damage in case a wrong de-icing is used. Concrete requires 7 days of curing whereas asphalt can be driven on immediately. Concrete driveways do not perform well in resurfacing too. All materials have their own advantages and disadvantages.
