The challenge
To revegetate a relatively steep, sandstone-based rock batter near the Caloundra exit on the Sunshine Coast motorway project without using subsoil amelioration and/or topsoil or compost treatment.
The solution
Our team applied EnviroMatrix®ECM Biotic Soil Amendment hydromulch at a rate of 10 tons per hectare and EnviroBond storm-guard polymer at a rate of 400 litres per hectare, in order to provide a high-strength durable bond of the applied EnviroMatrix Biotic Soil Amendment. This was intended to provide immediate and medium-term soil erosion control, as well as a suitable growth amendment for seed germination that would allow for plant establishment and provide long term soil-erosion control.

The results
Just seven months after application, native vegetation was establishing successfully on the BioGrowth-treated site, with minimal soil erosion. Our team applied EnviroMatrix®ECM Biotic Soil Amendment hydromulch at a rate of 10 tons per hectare and EnviroBond storm-guard polymer at a rate of 400 litres per hectare, in order to provide a high-strength durable bond of the applied EnviroMatrix Biotic Soil Amendment.
