What Surfaces should I Seal with Concrete Sealer?

Based on the provided guide, professional concrete sealing is a critical maintenance step for several types of residential and commercial surfaces to protect them from Denver’s harsh climate.

You should seal the following concrete surfaces:

  • Driveways: Professional sealing is highly recommended for driveways, especially those that are south-facing (due to intense UV exposure) or sloped (due to water runoff issues).
  • Patios and Walkways: These flatwork surfaces are vulnerable to moisture absorption, which can lead to cracks and pitting during freeze-thaw cycles.
  • Structural Slabs: Sealing helps protect the integrity of foundational or structural concrete slabs from soil and moisture conditions.
  • Commercial Plazas: High-traffic commercial areas should be sealed to prevent discoloration and damage caused by heavy pedestrian wear and de-icing salts.
  • Retaining Walls: Sealing is beneficial for vertical structures like retaining walls to prevent efflorescence (mineral deposits) caused by drainage issues.

Regularly sealing these surfaces every 2-3 years acts as a protective barrier against water, de-icing salts, and sun damage, significantly extending the life of your concrete and preventing the need for premature replacement.
