All catch basins / storm drains will either settle or deteriorate over time. This is because as water enters the joints between the steel casting and block or the mortar joints, it causes the water to disintegrate the mortar.
When this happens, especially during the colder months, the water will expand and contract causing the mortar to “pop out”.
In addition, cracks will sometimes appear around the perimeter of the storm drains and allow water to infiltrate the casting.
When any of these deficiencies occur or with a combination of them together, this will deteriorate the integrity of the casting or structure and the following will happen:
Our rehabilitation services can be as simple as patching the asphalt around the perimeter with a quick mortar repair, to an in-depth scope of complete structure rebuild.
Structurally concrete will last 4 times longer than asphalt as a collar for storm drain repairs. Even after rebuilding and parging the inside of a catch basin there is still a risk water will migrate between the asphalt and the cast iron frame at some point in the future. In the winter this water will turn to ice and over time will damage the block. When asphalt is used as a collar and the brick begins to deteriorate a sink hole will develop around the perimeter.
Once the sink hole develops it will only be a matter of time and the weight of a parking lot sweeper or snow plow truck before the catch basin perimeter collapses.
When concrete is used in place of asphalt it has much greater tensile strength combined with steel reinforcement similar to concrete bridge decks. If a bridge deck was to develop a hole through the entire substrate, the bridge deck would remain in tact as the steel reinforcement would keep the surrounding concrete together. In the same theory, if a sink hole was to develop around the perimeter the concrete would bridge the hole and prevent the concrete from sinking into the catch basin.
Concrete collars around catch basins are installed between 6" - 12" thick and range in perimeter from 12" - 36" wide.
For an asphalt perimeter rebuild costs range from $2,200.00 - $3,000.00. For a concrete perimeter costs range from $2,500.00 - $3,500.00.

We will inspect your catch basin(s) for damage and email you a quote the same day from the site after our inspection with pictures and an itemized report.
