BioMix is a manufactured topsoil that is highly resistant to erosion. BioMix ingredients are Fiberlime (short paper fiber), compost, and a mineral base soil - most of which we source from residual streams that would otherwise go to waste. Most cost-effective is when an end user can provide a suitable base soil (mineral sand or a low quality loam), then we provide the Fiberlime and compost, recipe blend recommendations, and technical assistance to mix the blend onsite.
BioMix has been used to stabilize soils and establish grass cover on over 100 construction sites since 1990. We are so confident that BioMix will work on your site, that we offer a written grass growth guarantee!
BioMix is easily created by mixing using conventional construction equipment. Casella Organics' soil specialists provide a simple bucket to bucket mixing recipe and are onsite to provide oversight and to help maximize efficiency.
