Unsealed concrete naturally absorbs water. When this water freezes it expands in volume by 9%. This expansion puts stress on the concrete that causes it to spall and flake.
Many people treat their concrete driveways and sidewalks with salt during the winter. This salt soaks into the concrete. When the temperature drops below the working temperature of the salt, the water refreezes. This water again expands and puts pressure on the concrete and causes it to spall and flake.
The de-icing salt can cause the steel reinforcement in the concrete to corrode. This further weakens the concrete and can cause cracking and failure.
By far the most common type of concrete driveway or sidewalk is the natural look of a brushed concrete installation. We use a sealer that preserves this look so that you do not have a glossy look.
Decorative concrete is becoming a popular feature of many homes. The concrete can be colored or stamped to look like stone, brick or other natural building material. It is common for these to be coated with a glossy sealer. We can apply a sealer to bring out the color and maintain the wet and glossy look while protecting it.
We will sweep the concrete and clean it if needed. Then a trained technician will apply the correct water repellent to seal your concrete.
