Prevent Concrete Damage, Remove De-Icing Chemicals after Snow and Ice Melt

Friday, February 6th, 2015

Concrete Damage De-Icing ChemicalsConcrete is a durable material that’s excellent for sidewalks, curbs, dumpster pads, and similar structures. Concrete is durable, but it’s not indestructible.  It requires regular maintenance and proper protection, especially during the winter months when the freeze-thaw cycle and de-icing chemicals can wreak havoc on concrete.

De-Icing Chemicals and Concrete Damage

If you have ever visited the My Pavement Guy blog before, you know owner Patrick T. Gillen III is strongly against the use of de-icing chemicals on concrete and asphalt surfaces. These chemicals, while great for melting snow and ice, also ““interact with concrete, resulting is cracking, strength loss, and eventually pavement failure,” according to a 2002 federal government-funded study.

“No de-icing chemicals are safe.” – Gillen.

Sand is a much safer and environmentally-conscious option. Still, if you want to use de-icing chemicals to melt away hazardous ice and snow (we understand. Slips, trips, and falls can be a liability), it is important to remove these chemicals when they are no longer necessary. Far too often, business owners and property managers who use de-icing chemicals fail to properly remove these chemicals when snow and ice have melted away.

Leaving clumps of de-icing chemicals, like salt, on your sidewalks, dumpster corals, and other concrete surfaces can lead to concrete damage, such as cracking or worse, total pavement failure. When concrete becomes cracked and broken, it not only detracts from the overall look of a property, it can become a safety hazard.

Concrete Repair from PTG Enterprises

The secret to great looking pavement is three-fold: initial construction, maintenance, and re-construction. And lucky for you, PTG Enterprises can handle all three phases. We are a commercial concrete contractor in the Baltimore area and our crews are extremely familiar with all types of concrete paving.

PTG Enterprises are experts with commercial concrete jobs.

According to the Federal Highway Administration Manual of Practice (FWHA Report Number FHWS-RD-99-147), “Crack sealing and filling are imperative preventative maintenance tools.”

Concrete Damage: Shrinking, Curling, and Cracking

Friday, May 16th, 2014

Concrete is a strong, durable material that holds up well to the elements. Because of this, concrete is excellent for sidewalks, curbs, dumpster pads, and similar structures. However, concrete is not indestructible. In fact, it immediately starts to break down soon after it is poured. That is life. All god things must come to an end. Yadda yadda yadda. I am sure we could throw around a million other clichés as well.

Concrete Damage: Shrinking, Curling, and Cracking

Concrete damage occurs in three ways. It shrinks, it curls, and it cracks.

Concrete Shrinks

Concrete shrinks as excess water is removed as the concrete dries. The length change can vary between .01% and .1%. This is inevitable. There is no way to stop concrete from shrinking. There are, however, ways to minimize the damage this shrinking can cause, namely, reinforcement, proper installation, and regular maintenance. These simple steps will help control the severity of shrinkage cracks.

Concrete Curls

“It is normal to expect some amount of cracking and curling on every project,” explains the American Concrete Institute (ACI).

Over time, concrete tends to curl up around its edges and at joints as the result of shrinkage (see above). The top of the concrete dries out or cools quicker than the bottom. As a result, curling occurs. This causes the pavement to lose contact with the subbase and thus lose integrity, which can lead to cracking.

By reducing and better controlling shrinkage, curling can be minimized. This, once again, comes down to reinforcement, proper installation, and regular maintenance.

Concrete Cracks

All concrete will develop cracks at one point or another. This can happen for a number of reasons, ranging from improper installation and shrinkage to subgrade settlement and more. This cracking is only worsened by harsh winters (like the one we just had) and what is known as the freeze-thaw cycle.

Fortunately, unlike curling and shrinkage, cracks can be easily repaired.
