There are certain conditions under which using a repair compound or resurfacing product may result in only a short-term fix. Under these conditions, patching the concrete prior to resurfacing or doing a decorative topping would not be a cost-effective solution, as the surface or topping could soon display the same characteristics as the concrete that was previously repaired.

These conditions include:

•  Deep, widespread cracks where settlement has occurred. This may be due the weight of large trucks, improper preparation of sub grade, erosion of sub grade, or for other reasons.

•  Concrete that has sunk, which may occur if the sub-base wasn't prepared properly. Loose dirt may have been used for the sub-base. When this dirt settles, sometimes due to sprinkler or rainwater going under the concrete, the

concrete is unsupported and will be more susceptible to sinking.

•  Concrete that show obvious signs of frost heave. Frost heave is very common in cold climates. Moisture in the ground freezes and the concrete pushes upward.

•  Concrete that has so much spalling or pitting on the surface, that is it more economical to replace the concrete, rather than prepare the entire surface and resurface.

CONCRETE REPLACEMENT

CONCRETE REPLACEMENT PROCESS

• STEP 1

Removal and cleanup of the old surface is the first step so we can start with a clean slate and prepare to add the new base.

• STEP 2

Sloping and grading of the new base is done to make sure there will be proper water drainage. Water damage is a major cause of damage, such as cracks and heaving.

• STEP 3

A new sub-base is installed and compacted, this is key to ensure the new concrete has a solid base. The sub-base is a frost barrier to help reduce winter damage due to freezing and thawing.

• STEP 4

Forms are now installed around the area where fresh concrete is to be poured, forms are a guideline to ensure that the new concrete is poured at proper depth, graded for water run-off and joins level to any existing concrete or asphalt.

• STEP 5

Reinforcement steel and expansion joints to prevent cracking during freeze/thaw conditions is then installed.

• STEP 6

The new concrete is then poured and finished. When the concrete sets, we return to remove forms and clean up debris.
