Attenuation
Attenuation crates: which brands do we work with?
We're system-agnostic — we install to the drainage design, whatever crate it specifies. Here's how we think about crate selection.

One of the questions we get most often: which attenuation crate do you use? The honest answer is — whichever one the drainage design specifies. We're installers, not a single-brand shop, and different jobs call for different crates.
What actually decides the crate
- Loading class — landscaped areas, car parking and adoptable highway all demand different structural ratings.
- Depth of cover and the loads passing over the tank.
- Void ratio and how much storage you need in the available footprint.
- Whether the system needs to be inspectable or jettable for maintenance.
Supply-and-install or install-only
We'll supply crates to the specification, or install crates you've already procured — install-only is a normal way to work with us. Either way, what we're accountable for is the same: the wrapping, the welding, the testing and the documentation that make the tank hold its designed volume.
The point
Don't get too hung up on the badge on the crate. Get the loading class and volume right for your site, install it properly, and test it. That's what keeps the tank working — and that's the part we bring.
