A Green foundation is the point at which your home connects to nature. We’re talking: cold, moisture and pests. You can deal a lot of the cold aspect with good sealants and thorough caulking. This is not a typical concern of a new homeowner, but as a Green home builder, you will want to monitor everything. Especially where energy loss can occur.
Trying to include recycled material in the foundation of your green home can also make a huge difference in cost and in your impact on the environment. Persuade your builder to work with you on locating recycled CMUs or at least using recycled concrete aggregate as a coarse fill below grade. (Take care to avoid moisture problems around your foundation; this is nothing new to green home building.) You can also specify recycled content in your concrete, such as fly ash and slag. Take this opportunity to install insulation for your concrete forms.
To avoid pest problems, and the later use of environmentally harmful pesticides, make plans now. Use permanent pests shields – especially termite shields – around the perimeter of the house. Employ plastic and metal dividers and fasteners to separate wood and concrete along the perimeter of the foundation from the surrounding ground.
And while you’re at it, protect your foundation form invasive roots by moving your shrubs and trees at least 3 feet from the house perimeter. A green home or any other can’t be happy without a sound foundation. These efficient building practices can be applied to any house plan.
