Concrete Treat Prevents Concrete Spalling, Scaling and Flaking Problems

Protect Outdoor Concrete, Including Sidewalks and Walkways, From Chipping & Damage

Steps to Concrete Spalling

  1. Concrete is poured and set with a weak top layer.
  2. Moisture migrates underneath the top layer and builds up underneath.
  3. Freezing temperatures cause water to expand to 109% of its previous size, placing pressure on the concrete above.
  4. As the pressure builds, the concrete "pops", causing flaking and chipping of the concrete's surface.

Concrete Treat: Concrete Blanket & Sealer is able to be applied to both dry and wet concrete to create a moisture-proof barrier on the materials surface.

It protects your concrete's surface from damages caused by freezing moisture, ultraviolet rays, and salts, applying easily and drying within 2-4 hours.

Most importantly, it can seal the concrete's surface to protect it from spalling, scaling, flaking, and chipping of concrete that occurs in new construction during cold weather.

What is Concrete Spalling and Scaling?

"Spalling" is a term use to identify concrete that is chipping, flaking, or similarly damaged.

Concrete spalling, also known as "concrete scaling" is the name used for the flaking and chipping of concrete that sometimes occurs in new construction and in wet basements that have been sealed with hydraulic cements.

Spalling and scaling of concrete is most often caused by a combination of freezing temperatures and improper mixing and "creaming" of concrete during construction.

Moisture and water can make its way underneath the top layer of concrete and build up there. During periods or repeated freezing and thawing, the moisture will freeze, causing it to expand as much as 9% of its previous volume.

This creates pressure on the top level of the concrete, causing the top layer to "pop". This leads to chipping and flaking of the finish-- an unattractive mess that makes the new construction look unsightly and unprofessional.

Concrete Mixing and Spalling

The mix of concrete as it's poured significantly contributes to how likely that concrete is to spall, chip, scale, and flake in the future. Concrete should be mixed and set with proper air entrainment in mind (a minimum of 4% air in mixture), allowing for enough airspace within the concrete to handle the expansion of the water.

Additionally, to avoid spalling, a compression strength of 4,000 PSI should be used, with a minimum of 564 pounds of concrete/yard placed. The water/concrete ratio (known as the "slump"), after mixed, should be no more than .45.

Concrete should also be mixed with the proper mix of sand, cement, and aggregate-- too much sand and cement, and not enough aggregate, will often lead to a weak top layer that increases the chance of damage from spalling.

To avoid a thin, weak surface on the top, it's also important to be careful when finishing the concrete. Concrete that has been overfinished, or has had water added to the mixture after it's down, can easily spall. When concrete is overworked, a creamy layer of concrete is brought to the surface.

Prevent Concrete Spalling and Scaling with Concrete Treat!

Rock salt, de-icer, and winter freezing can deal a great deal of damage to outdoor concrete.

Concrete Treat: Concrete Blanket and Sealer acts as both a curing compound and a concrete sealer for new construction applications. Once applied, it keeps salt and water from entering wet and dry concrete from the top. It's able to be applied in temperatures as low as 28 degrees Fahrenheit, unlike the 40 degrees Fahrenheit recommended by other concrete sealers, and it can be applied in one application as soon as the concrete has been placed. Once hardened, it creates a waterproof glasslike silicate barrier on the concrete that stops rain, humidity, hail, ice, and snow from seeping into the concrete.

By keeping moisture out, it stops the concrete from freezing. And if it can't freeze, then it can't pop, right?

Concrete Treat eliminates the need for the application of concrete blankets- once seen as a necessary evil in the concrete construction industry. This means that the long process of loading the blankets into the truck, hailing them to the site, and hoping they don't tear as they're placed on the slab is eliminated-- as well as the long process of removing them and hauling them away. With Concrete Treat, all you have to do is spray it on, wait 2-4 hours for it to dry, and your concrete is protected from cold and moisture.

With Concrete Treat, you'll save unnecessary steps, costs, and ordering complications! Call or e-mail us today to learn more about ordering Concrete Treat for your new construction!
