Do You Have a Concrete Patio? A Few Problems That May Arise and What to Do about Them

Blog

Whether you are about to have a ready-mix concrete patio poured or you already have one in place, knowing the different problems that can arise and how to fix them will keep the area looking good. The most common problems you will encounter include discoloration, scaling and cracking. While cleaning, and sealing concrete can inhibit problems, they will not stop them altogether. Here are a few tips that will fix the troubles.

Discoloration

Discoloration can be caused when the concrete is initially poured. If the slab is not all poured at the same time, or in the same temperature, the finish may be slightly different. If the discoloration occurs later, it is usually due to chemicals on the pad. If a good pressure washing does not remove any spots or blotches you can use a concrete stain over the entire surface. Use a stain that will also seal and protect the slab to keep discoloration from happening again.

Scaling

When layers of concrete flake away, it is called scaling. The most common cause of it is water seeping into the pores, freezing and then melting quickly. Prevention is best for scaling. Prevent water from pooling on the concrete. Be sure to push off any standing water after a rain or cleaning. Once scaling has occurred, you will need to apply a thin layer of concrete on top of the slab. Once dry, be sure to use a sealant on the entire patio.

Cracking

Concrete can crack due to stress, temperature changes and settling. If you see several hairline cracks, they are due to the concrete shrinking as it cured. To fix these cracks, a thin new layer can be applied to the area. Larger cracks, caused by settling or changes in temperature can be repaired with a concrete epoxy. This comes in two separate tubes or pouches. Mix them according to the manufacturer's directions and then fill any cracks.

Once you have filled any cracks or applied a new layer to repair scaling, you may need to stain the dry concrete to keep the color smooth and even across the whole patio. Apply new sealer every two to three years to limit any further damage. Regular maintenance, including rinsing the patio when it gets dusty, will also help keep things looking good. In freezing weather, avoid using water on the patio, instead blow any dirt and debris off with a leaf blower. You don't want the water freezing in any tiny cracks or crevices.

Make Your Walkway Wonderful

I own a small office building, and recently, I was looking for ways to improve the building's exterior. I felt that the whole office was very plain and lacked curb appeal. I want clients and business contacts to be impressed by the building and the grounds before they even step through the door. I knew that one thing I definitely needed to do was replace the crumbling walkway. I called a concrete contractor about fixing the walkway, and was impressed when he told me that I could actually make it look like a brick pathway, using stamped concrete. I decided to go for it, and it made a big difference in the appearance of the outside of the office. I think that more people should be aware of how they can use stamped concrete to improve their business's curb appeal.
