FAQs
Are these crates structurally sound despite the damage?
Yes. Only corners or sides are damaged. Load-bearing and storage capacity remain unaffected.
Can they still be installed under trafficked areas?
Yes, they retain their 440kN/m² compressive strength rating and are suitable for use under driveways, car parks, and access roads.
Is a geotextile membrane necessary?
Yes, for infiltration systems use NW8 fleece. For attenuation (sealed tanks), use an impermeable geomembrane with protection fleece.
