Rainbow is a civil engineering and environmental company with over 25 years’ experience in its field. From humble beginnings, Rainbow Excavations Pty Ltd was established in 1985 as a small, family owned, plant hire company.
Today, Rainbow Group specialises in all civil and environmental works including bulk and detailed excavation, road and civil construction, sub-divisions, streetscape upgrades, environmental remediation, and demolition.
Soilco has been working with Rainbow Group supplying specified drainage materials and bio-filtration media for a site in Unanderra. Three basins with a total area of 737m2 have been designed and installed. The purpose of the basins is to direct, contain and filter stormwater runoff from the site. Concrete was shot around the perimeter to key in the clay liner and grass species will be planted across the base.
Soilco supplied Rainbow with nearly 500 tonnes of Soilco Bio-filtration Media, in addition to transition and drainage material. Features of this product include meeting specific hydraulic conductivity requirements and organic matter and nutrients can be adjusted to meet plant growing requirements.
