Permeable paving has been recognised in recent years as an alternative approach to dealing with stormwater runoff and pollution control.
Water needed by trees for nourishment usually becomes runoff that requires an engineered and often costly solution to control, collect and treat. Usually this involves a stormwater control system channelling any stormwater runoff through a system of open drains and stormwater pipes to reduce flooding, surface ponding and erosion, followed by treatment for pollutants and eventual discharge.
Permeable paving has been recognised in recent years as an alternative approach to dealing with stormwater runoff and pollution control. The Hydrapave and Ecopave systems are perfect for:
Surface run off control
Storm water retention
The Ecotrihex® concept is specifically designed for drainage systems that incorporate surface runoff, storm water retention, public areas, car parks and tree surrounds. Choose between charcoal, ivory, oatmeal, salmon, sunstone, and terracotta.
Ecotrihex® was used extensively around the Sydney Olympic stadium as an environmentally friendly solution to water recovery while providing the visual appeal of great design style. Manufactured from high strength concrete, they are exceptionally tough and durable and are able to maintain their performance over a long period of time.
The Hydrapave™ system allows water to infiltrate through 4mm deep vertical channels at each end of the 80mm thick concrete Hydrapave™ pavers and into a prepared 50mm bedding course, where pollutants are filter treated naturally.
The water is then dispersed into the sub base through a series of graded gravel layers, penetrating to the trees’ root systems through the pavement and via the specially prepared ‘structural soils’ beneath, to a final layer comprising a 50/50 mix of topsoil and 50mm diameter multi-faceted basaltic rock – used as a growing medium for new trees.
Any excess water is drained away through an agricultural drain into the stormwater system by means of an agricultural drainage system
