Precast Catch Basin FAQs (Frequently Asked Questions)
Looking for quick answers about production, design, and installation for your precast catch basin? Search for them in our precast catch basin FAQs tool below.
What are some design considerations pertaining to catch basins?
- Stormwater runoff rates based upon storm event recurrence
- Sediment volume, density, and re-suspension
- Anticipated surcharge loading on the structure
- Soil bearing capacity below the structure
- Ease of access for future maintenance and/or cleaning
What equipment and supplies are necessary for precast catch basin installation?
- Excavator or backhoe
- Vibratory compactor and/or sheep’s foot roller
- Any proper bracing that is required
- Sealants, grouts, and mastic as required
- All proper safety equipment and PPE
Where are catch basins typically installed?
Catch basins are often used along sidewalks and streets, or in open yard spaces with drainage problems.
What are some advantages of precast that installers need to know?
- Ease and speed of installation
- In-stock availability of many standard sizes
- Customization to fit project needs
- Compelling upfront costs as many required materials are supplied by producers (ie. Sealants, grates, mastic)
- Dedicated and knowledgeable sales staff
What are the steps of installation?
You can find basic instructions for typical installation here.
Why should I use precast catch basins for my next project?
Installation is fairly simple. A small group of professionals can complete the installation using basic machinery.
What are some advantages of precast that designers need to know?
- Unmatched durability and strength
- High quality concrete mix designs
- Documented QA/QC programs
- Easily customizable to meet project needs
How complicated is precast catch basin installation?
Small equipment enables the installation of most products in just one day.
What is the difference between a knock-out and a block-out catch basin?
Pipes fittings for block-outs are either cast-in during the production process or cored before product delivery. In contrast, knock-outs feature a thin wall that installers can break out during the installation process to achieve the desired size and shape for the pipe fitting.
What are the main considerations in sizing catch basin parameters?
Designers should determine the appropriate size of a catch basin by considering the anticipated stormwater runoff rate and the volume of water to be stored. They can then calculate the catch basin’s required volume to accommodate this water. Municipalities establish specific regulations governing the amount of water allowed into the stormwater system. The difference between the regulated and incoming water amounts dictates the necessary capacity and, consequently, the overall size of the catch basin. Next, designers must assess the size requirements of the inlet and outlet pipes based on the volume they need to convey. For more detailed information, visit our technical resources page.
