Catch Basins for Stormwater

A catch basin, also known as a storm drain, is used to redirect water to prevent flooding. Catch basins are essentially sumps, located directly under storm drains, and are designed to hold standing water. They are commonly seen on public streets but may also be used to control storm waters on private properties. Catch basins collect precipitation and funnel it to a reservoir or treatment plant.

Flexible liners can be used in the creation of a catch basin and come with many benefits which include:

  • relatively low installation costs
  • custom fabrication, allowing for factory seam sealing
  • lightweight
  • easy to modify, allowing pipes to be moved, new holes to be cut and old holes patched when a high durability material such as RPE is chosen
  • durable; lasting decades especially when installed away from the sun’s damaging ultraviolet rays (i.e. underground)
  • easy to inspect and test for leaks
  • smooth surface improves the cleaning process
  • resists damage from chemical stormwater contaminants, especially if a multi-layered liner such as RPE is chosen

Don’t let shape and size limitations of preformed basins control your project. It’s easy to build a custom catch basin to meet any need using a versatile, multi-layered, reinforced, polyethylene (RPE) material such as BTL’s AquaArmor. Crafted to resist the harshness of any catch basin environment, AquaArmor is the strongest, most reliable catch basin liner on the market. Additionally, AquaArmor is 100% fish and plant safe, meaning it will not add pollutants and contaminants to the water that will cause harm to fish and plants further down the line as the water makes it to its final destination.  Visit to learn more.
