Catch basins work as a drainage system for your parking lot. They are built into an asphalt or concrete parking lot to redirect stormwater.
All catch basins will settle or deteriorate over time. As water enters the basin, the joints between the frame and grate casting, blocks, or mortar joints become weak. The water will eventually disintegrate the mortar. It's very simple.
When this happens, especially during the colder months, the water will expand and contract in the openings. This causes the mortar to “pop-out”. This can cause a large issue in your parking lot.
In addition, cracks can appear around the perimeter of the catch basin and allow water to infiltrate the casting.
The Technical Stuff:
If either of the above happens, the catch basin may begin to settle around the perimeter. This will further allow standing water to accumulate.
If it's winter, the standing water will freeze and may become a potential liability.
At this point, the asphalt around the basin may begin to see some cracking. As the cracks continue to spread outward the asphalt will begin to deteriorate.
The casting may settle as the mortar “pops out” and an asphalt lip may appear. This will cause a tripping hazard. This happened because a section of the casting or wedge blocks may have fallen out from normal parking lot traffic. Worst case, the top row of the block may completely fail and allow the casting to cave in.
Our catch basin repair services can be as simple as patching the asphalt around the perimeter with a quick mortar repair, or we could provide an in-depth scope and complete structure rebuild. Either way, we will get your catch basin working.
We are available 24/7 for all of your NJ Catch Basin repairs. Most repairs can be completed within 24-48 hours of calling. Call 877-249-2774 today
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 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 sinkhole will develop around the perimeter.
Once the sinkhole 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 intact as the steel reinforcement would keep the surrounding concrete together.
In the same theory, if a sinkhole 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. For more in-depth rehabilitation the cost could be up to $5,000.00
What dictates the cost:
STEP 1: (Determine Cause) Our objective is to locate the source of the water that had lead to the catch basin failure. In the example above, the water has entered the basin from behind the frame and migrated through the block.
STEP 2: (Interior Inspection) We remove the grates to perform an interior inspection. In the pictures above it shows how the water has entered the basin from behind the steel casting and through pressure from freeze/thaw the bricks have been pushed out into the interior of the basin.
STEP 3: (Email Quote) A company representative will provide you with a quote via email or text from an iPad in the field.
We can also provide a video from the field to document our findings
