RMI’s soil amendments are extremely versatile, and as such, we’ve supplied these recycled, sustainable materials for all kinds of unique projects throughout the Northeast. This year, we will be revisiting and sharing some of these engaging projects of the past as well as posting more of our current success stories!
Back in 2001, RMI was recommended to the city manager overseeing the closure of a landfill in Claremont, NH, who required approximately 25 acres worth of viable topsoil that could effectively cover and sustain hearty vegetative growth over the capped landfill. Topsoil used for this application must be extremely erosion resistant to maintain the integrity of the site, especially if the land is sloped and/or located close to a body of water. We encountered some skepticism at first about our soil’s ability to meet the unique needs of the job. However, after learning that our Manufactured Topsoil would be erosion resistant enough on its own where an application of erosion control fabric would not be required, we were chosen for the job.
Staff at RMI managed the permitting and testing and created a material blend tailored to the exact nitrogen and long-term nutrient needs of the site. The closure required approximately 1350 cubic yards of topsoil per acre, placed to a depth of approximately nine inches over the geotextile mat. After planting a wildflower mix (our signature on jobs back in the day) a lively plant cover grew shortly after seeding, thriving with little additional input. Our manufactured topsoil excelled in this application and was estimated to have saved the city around $350,000.
