Clean Fill
Uncontaminated soil free of debris, ideal for grading and structural fill
What is Clean Fill?
Clean fill, also known as clean dirt or structural fill, is one of the most commonly used materials in construction and landscaping projects. It consists of natural, uncontaminated soil, rock, sand, gravel, or similar inert materials that are free from hazardous substances, organic matter, and construction debris.
The term "clean" refers to the absence of contaminants such as petroleum products, chemicals, metals, or other pollutants. This makes clean fill safe for use in a wide variety of applications where soil stability and environmental safety are important.
Clean fill is typically excavated from construction sites, road projects, or land development operations where excess soil needs to be removed. Because it's a byproduct of other projects, clean fill is often available for FREE or at very low cost – you just need to arrange for pickup or delivery.
