Protect Your Concrete Before Winter: Why Waterproofing Matters in Colorado

Colorado winters can be hard on concrete. Snow, ice, freezing temperatures, and de-icing salts all put driveways, sidewalks, patios, and other exterior concrete surfaces through months of repeated exposure.

One of the best ways to protect exterior concrete before winter is with a penetrating concrete sealer.

At Concrete Sealers, we use penetrating waterproofing treatments designed to reduce the amount of water and de-icing chemicals that can enter the concrete while maintaining the natural appearance of the surface.

Why Water Is a Problem for Concrete

Concrete may look solid, but it is naturally porous. Water can enter the pores and small cracks in the surface.

During Colorado's winter temperature swings, moisture inside the concrete can freeze and expand. Repeated freeze-and-thaw cycles place stress on the concrete and can contribute to surface deterioration over time.

This damage may eventually show up as scaling, flaking, pitting, or spalling.

Keeping water from penetrating as deeply into the concrete can help reduce one of the major contributors to this deterioration.

De-Icing Salts Create Another Problem

Water isn't the only concern during a Colorado winter.

Vehicles can carry de-icing chemicals from treated roads onto residential driveways and garage approaches. Salt and de-icing chemicals can also be introduced when homeowners use ice-melting products around their property.

Once dissolved in water, these chemicals can travel into porous concrete.

Over time, repeated exposure to moisture, chlorides, and freezing conditions can contribute to concrete deterioration.

That is one reason penetrating sealers are commonly used on concrete exposed to harsh winter conditions.

How Penetrating Concrete Waterproofing Works

Penetrating sealers work differently from traditional topical concrete sealers.

Instead of creating a coating or glossy film on top of the concrete, a penetrating sealer enters the pores of the concrete and creates water-repellent properties within the surface.

This helps reduce the absorption of water and waterborne contaminants while allowing the concrete to maintain a natural appearance.

For homeowners who don't want their driveway or sidewalk to look glossy or coated, this can be an excellent option.

Our Concrete Waterproofing Process

Our process begins by thoroughly pressure washing the concrete to remove dirt, debris, and surface contaminants.

After the concrete has been properly prepared and allowed to dry as required, we apply two coats of a silane-siloxane penetrating sealer.

The goal is simple: reduce water penetration without changing the concrete into a glossy or coated-looking surface.

What Concrete Can Be Waterproofed?

Penetrating concrete sealer can be a good option for many exterior concrete surfaces, including driveways, sidewalks, walkways, patios, porches, steps, and other porous concrete around the home.

The condition of the existing concrete matters. Concrete that already has certain coatings or sealers may require additional preparation or may not be suitable for a penetrating treatment without first removing the existing material.

That is why we evaluate the existing surface before recommending a waterproofing treatment.

Waterproofing Doesn't Repair Damaged Concrete

It's important to understand what penetrating sealer does and doesn't do.

Waterproofing is designed to protect concrete, not repair existing structural damage. It will not close existing cracks, repair spalling, or restore concrete that has already deteriorated.

The best time to protect concrete is before significant deterioration occurs.

If your driveway, sidewalk, or patio is currently in good condition, applying a penetrating sealer can be a preventative step to help protect that investment from Colorado's weather.

Is Your Concrete Ready for Another Colorado Winter?

If water quickly darkens your concrete when it gets wet or appears to soak directly into the surface, your concrete may benefit from a penetrating waterproofing treatment.

Concrete Sealers provides professional concrete waterproofing throughout the Denver area using penetrating sealers designed for exterior concrete.

If you'd like to find out whether your driveway, sidewalk, patio, or other concrete surface is a good candidate for waterproofing, contact Concrete Sealers for an evaluation and estimate.
