What is a Catch Basin?

A catch basin is also referred to as a storm drain. It is a drainage system typically used in parking lots and other concrete surfaces. You will also find these basins on residential streets.
The top of the catch basin or storm drain will have a grated steel protector fitted over the water entry point. Catch basins are designed to filter out debris and drop water into a sump for proper draining. The sump also acts as a back-up filtration center that can prevent blockages from sticks and other debris.

How does a catch basin break, then? The reality is that concrete and mortar are easily degraded by water flow and water pressure. As your drain ages, it will naturally fall apart. It’s why catch basin repair is such a common maintenance requirement where proper drainage is important.

What Happens If your Catch Basin Isn't Working?

While many property owners and managers don’t pay much attention to catch basins, it is an extremely important component of modern drainage systems. Below, we discuss the consequences of a faulty catch basin.

Flooding

If your basin degrades or contains too much debris, it won’t be able to drain properly. In many cases, it can cause a severe flood, which can have devastating consequences. It’s essential to ensure your catch basin is in working order, especially if you’re in an area that receives copious rain.

Odours

Catch basins typically have a mechanism that prevents sewer odours from rising to the street level. You’ll find that a non-functioning catch basin may begin to emit odours, though. If you notice sewage odours in the vicinity of your storm drain, it might need to be repaired.

How to Repair a Catch Basin: Step by Step

Step 1: Cut Around Catch Basin

A saw is used to cut the area around the catch basin and remove the asphalt protecting the internal components.

Step 2: Remove Asphalt and Other Damaged Concrete or Mortar

An inspection of the internal concrete and mortar will occur to remove all the damaged components.

Step 3: Replace Damaged Concrete or Mortar

Any internal components or eroded concrete must be replaced in this stage of the repair process.

Step 4: Replace or Reset Original Grate

The original grate will be reset to the catch basin. If it is damaged, a new grate will be used.

Step 5: Install Concrete Drain Collar

A drain collar of asphalt is paved around the area to protect the drain and other components of the catch basin.

Step 6: Clean Up Site

All debris and excess concrete should be removed from the site.

Step 7: Prep for Safety

Once repaired, it may take a while until the concrete sets and the area is accessible again. Barricades or protective signs are required to direct the public away from the job site.

Contacting Professionals

While this article contains most of the steps you need to repair a catch basin, it’s still a good idea to contact a professional team with considerable experience. Repairing a catch basin and restoring it to its former standard can be difficult work if you don’t have experience in plumbing or concreting. Using a professional team can increase turnaround and avoid drainage issues.
