A low-profile stormwater attenuation crate designed for shallow dig applications.

The Shallow Storm Crate 100Litre from Pennine Manufacturing is a compact, high-strength crate used for stormwater management. With a low overall height of just 100mm, it’s ideal for sites with limited excavation depth, such as roof gardens, landscaped areas, and car parks.


Key Features

  • 100L capacity per crate – 10 units = 1m³ of storage

  • 91% void ratio maximises water retention

  • High compressive (>320kN/m²) and lateral (>150kN/m²) strength

  • Suitable for shallow installations with minimal cover

  • Supports a wide range of loading conditions

This crate is designed for attenuation and infiltration systems, storing rainwater during peak flow and gradually releasing it into the ground or drainage system. Crates can be wrapped in non-woven geotextile membrane for infiltration systems, or used with impermeable geomembrane to retain water for reuse (e.g., irrigation or toilet flushing).


Minimum Cover Depths (Based on Axle Weight)

  • 1 tonne: 200mm

  • 2 tonnes: 250mm

  • 5 tonnes: 300mm

  • 10 tonnes: 400mm

  • 12 tonnes: 450mm


Optional Geotextile Membrane (100gsm NW8)

If selected, the crate is supplied with a cut-to-size sheet of non-woven geotextile:

  • 1 crate: 2.25m x 3m (6.75m²)

  • 3 crates: 2.25m x 7m (15.75m²)

  • 6 crates: 2.25m x 13m (29.25m²)

This wrap prevents soil ingress while allowing water to pass through.
