Proper concrete maintenance is key to
preventing costly repairs. When a concrete slab needs to be replaced, the old
material needs to pull out before placing the new slab. This can get very
expensive as most concrete is a minimum of three and a half inches thick, which
makes the material very heavy. So in order to ease removal, the slab needs to
be saw cut or jackhammered to break it up into smaller pieces. Once the slab
is removed, the new stone base can be prepped. Typically, a concrete slab will
cost at least six dollars per square foot to replace. So regular concrete
maintenance is key.
So what types of maintenance are necessary
to keep your concrete in good working order? First, make sure all cracks are
sealed on a regular basis. Spring is a good time to go through all of your
exterior concrete slabs and check for gaps and cracks. You don't want water to
get down through the cracks and wash out the stone base below. This can create
settlement which ultimately leads to cracking and trip hazards. High-quality
concrete caulk is necessary to seal the
joints up. Check with your local concrete supplier for material
recommendations.
Cleaning is another concrete
maintenance item. Regularly cleaning your concrete surfaces will keep
carbon dioxide, acids, and chlorides from entering the concrete surface. Dirt,
saltwater, automobile fluids, deicers, and sand are filled with these corrosive
chemicals that can deteriorate the concrete surface. By keeping the surface
free of these items, you will help prevent surface spalling. When it comes to
cleaning your concrete, make sure you wait until the surface is at a cool
temperature. You don't want to put really cold water on a hot concrete slab as
it can put stress on the material that can lead to cracking.
Sealing your exterior slabs is another high-priority concrete maintenance item. One of the best ways to protect the surface
of your exterior concrete is to limit the amount of water that transports
harmful chemicals into the concrete's pores. Check with your local concrete
supplier for some really high-quality sealers. The best sealers penetrate the
material to provide long-lasting protection. Most of these can be applied with
either a plant sprayer or a simple paint roller.
These are some of the most important
concrete maintenance items for homeowners. But in addition to maintenance, it's
important the concrete is installed properly from the beginning. Here are some
general contractor tips for getting a quality concrete job.
1. Provide a four-inch compacted stone base
directly under the slab 2. Add control joints to control the
cracking in the surface 3. Air Entrained Concrete - Make sure the
proper concrete mixture is used for the local climate. 4. Not all concrete will
stand up to freeze-thaw cycles. 5. Water - Make sure your contractor doesn't
add water to the concrete truck on-site as this will weaken the material 6. Cure - Be sure to include a curing
compound or keep the surface of the material wet during the first few days
after pouring.Luda Proper concrete maintenance and installation will help you prevent costly repairs down the road. |
