Why Seal Your Concrete?

By Sarah Etler - 9/28/22, 5:23 AM

Sealing concrete is one of the most beneficial things a homeowner can do to preserve their concrete. When you seal your concrete, you are protecting it from the freeze-thaw cycles and other irreversible damage to your concrete.

One of our primary goals at A-1 is to help you keep your concrete as beautiful and long-lasting as possible. Concrete that has not been sealed properly will age much more quickly, and result in a need for replacement years before it should have been.

What is concrete sealing?

Concrete sealing is the act of applying a product to your concrete that creates a hydrophobic water barrier which causes water and other liquids to turn into droplets on the surface. The water then quickly dries or runs off the concrete slab instead of soaking into its pores. 

Concrete sealing helps protect against damage from spalling, chipping, crumbling, breaks, stains, sun exposure, salt, mold growth, and more.

Benefits of Sealing Concrete

The main benefits of sealing can be broken down into the following five categories:

  • Increases durability 
  • Inhibits mold growth
  • Adds protection from damage
  • Enhances beauty and curb appeal
  • Increases longevity

The following sections will discuss these benefits in more detail.

1. Increases Durability

Any concrete exposed to the elements will experience deterioration, including cracking, spalling, pitting, and discoloration. Sealing the concrete will make it much more durable and minimize the effects of weather on the concrete’s surface and sub-structure.

2. Inhibits Mold Growth

Concrete is porous. This allows water to absorb into the surface and remain there for long periods of time. In shady areas, this can oftentimes lead to mold growth. Without properly cleaning and sealing the concrete, this mold can actually help to break down the surface of the concrete, greatly shortening its lifespan.

3. Adds Damage Protection

Many influences work against the integrity of your concrete. From the harmful effects of the sun’s UV rays; to salt placed down to prevent ice build-up; to oil leaks or spills; and water penetration, there is a veritable army attacking your concrete every day. The proper sealant can protect against all of these attacks, keeping your concrete beautiful and strong.

4. Enhances Beauty and Curb Appeal

All of these external influences can greatly reduce the beauty of your concrete. The sun’s rays can discolor it. Oil can create a patchwork of dark stains. Mold can darken large sections. Sealing the concrete can mitigate all these influences, not only making it last longer but keeping it beautiful at the same time.

5. Increases Longevity

Most experts say a concrete driveway should last thirty years or more. But, the main consideration in the longevity of the concrete is how well it is maintained. Concrete sealing is the number one factor in helping your concrete last as long as possible.

Sealer Options Available

A-1 Concrete Leveling offers two varieties of sealers to keep your concrete looking great.

Penetrating Sealers

The first variety is a deep-penetrating, siloxane-based concrete sealant, which is absorbed into the slab to protect the concrete and preserve its longevity. This sealant creates a waterproof barrier which causes the water to bead on the surface. It is suggested that the concrete is cleaned and sealed every 7-10 years after this sealant is applied.


The second variety is a product called DensiCrete, which chemically alters silica within the concrete's microcracks and pores and creates new concrete. This densifies the slab to the point where it is unable to absorb water and helps to prevent issues with spalling and cracking in the future. This is a one-and-done solution and would not need to be reapplied in the future.

These are not the only options available. Learn more about the different types of concrete sealers and decide which is best for you, or leave it up to the professionals at A-1 Concrete Leveling by clicking the link below!
