Green Horizons Environmental stresses the importance of using local Fill Media in the Soxx for performance and savings. Native vegetation is the best choice, and native vegetation prefers native soils. Locally sourced Fill Media also saves on trucking costs to the job site. For instance, one project required 20 loads of Fill Media. Fill Media needs to be placed, graded, compacted, reinforced, and vegetated. This process is tedious and needs to be done correctly, but it is difficult to predict due to unsure nature of how materials locally compact. In addition, shipping products 50-100 miles would make our technology more expensive, but perhaps still less than traditional structural alternatives.  Locally sourced Fill Media simply saves you, the customer, money!
