Dumping excess fill dirt for free requires finding an interested party looking to take in the material. Websites such as Dirtfill.com, Freedirt.com and Clean-Fill-Wanted.com act as exchanges linking dirt providers with those looking for such fill. Depending on the arrangement reached, either the dirt provider or receiver transports the fill.
As of 2015, Dirtfill.com offers free registration for fill dirt providers and solicitors, except for three metro areas in the United States: Minneapolis and St. Paul, Dallas and Fort Worth, and Seattle, Tacoma and Bellingham. The site also provides suggested procedures and a frequently asked question page.
Fill dirt providers are required to pay to use Freedirt.com. The site's subscription fee ranges from $12.99 to $69.99 for monthly to yearly membership. Visitors who need fill register with the site for free. Similarly, Clean-Fill-Wanted.com assesses a flat fee to provide advertisements for provided fill dirt but only charges the fee if the dirt is taken at the end of a 12-week period.
Excess dirt is typically generated from forms of excavation in construction sites -- either residential, commercial or industrial. Most construction companies arrange in advance for the disposition of excess fill dirt, typically with a company that specializes in providing fill for other projects. New road construction, for example, often uses fill dirt as a base layer prior to laying down pavement.
