In addition to being a site work company, Southampton Excavation also has a full-service landscape supply yard located in Southampton, New York, which is fully permitted and regulated by the DEC for the sale and acceptance of materials. The yard accepts a wide range of materials including sand, concrete, fill, leaves and brush. These materials are recycled into mulch, compost, gravel, crushed concrete, and topsoil which are then resold. There are several benefits involved with operating a supply yard and using a supply yard by accepting recyclable materials that are related to landscaping. Rather then just dumping broken concrete or underbrush, we can recycle it. The process of recycling and reusing these materials is sustainable and better for the environment. Other landscapers or homeowners can then go to a supply yard and purchase mulch or gravel wholesale.
