Why is Fastfoot® Green?

Sustainable and livable buildings start with a foundation that minimizes construction waste, prevents pollution and is cost effective.

Fastfoot Conserves Resources

1 - Conserves Natural Resources

A single 12.5 pound roll of Fastfoot® forms the same footing as 900 pounds of lumber, representing a dramatic increase in efficiency. Footing lumber is discarded after several reuses because of alkaline damage. Fastfoot® protects all lumber and stakes from concrete.

The photo on the right shows the typical footing lumber on a residential foundation in Vancouver BC. The photo insert shows Fastfoot® with sewn corners, where not a single piece of lumber was used to form the concrete. The fabric stays in place to prevent ground moisture from entering the foundation concrete.

2 - Prevents Ground Water Pollution

Fastfoot® is a damp proof membrane and prevents concrete toxins from contaminating sensitive ground water. With lumber footing forms, the concrete is in direct contact with the ground, and cement fines enter the groundwater, contaminating spawning and wildlife habitat.

3 - Contributes to LEED® Points

There are seven categories where Fastfoot® contributes:

Main section Subsection Detail Explanation
1 - Sustainable Sites Prereq 1 Construction Activity Pollution Prevention With lumber footing forms, concrete is poured directly on the ground, contaminating the water table with cement toxins. With Fastfoot® the concrete is poured into a membrane, preventing all ground water contamination.
2 - Materials & Resources Prereq 1 Storage & Collection of Recyclables Lumber formed concrete footings are not environmental because of transportation, storage, and waste. Approximately 35% of lumber forms are sent to the landfill. Fabric forms are very green: 300 times lighter and 1% the space of lumber, and stay in place to prevent ground moisture entering the concrete and causing mold and health issues.
3 - Materials & Resources Credit 2.1 Construction Waste Management: Divert 50% from Disposal Fabric forms divert 100% of forming materials from disposal. Any lumber used is completely protected by Fastfoot® from concrete damage and is reused.
4 - Materials & Resources Credit 8 (Canada) Durable Building Fastfoot® prevents rapid hydration leading to stronger and more durable concrete. Lumber forms lead to excessive drying and weaker concrete.
5 - Materials & Resources Credit 8 (Canada) Durable Building Fastfoot® eliminates rising damp, thereby preventing the deterioration of the building structure and interior finishes from mold and dampness.
6 - Indoor Environmental Quality Credit 3.1 Construction IAQ Management Plan: during Construction Fabric forms for footings stay in place to act as a permanent membrane, preventing rising damp through the concrete and into the building interior. Elevated moisture levels are linked to mold and the proliferation of other indoor air borne pathogens that directly affect human health.
7 - Innovation & Design Process Credit 1.1 Innovative Performance not specifically addressed by LEED® Fabric formwork for concrete footings is a dramatic innovation over temporary lumber forms. This technology is not only more efficient than lumber forms, but offers ongoing benefits to the building occupants for the life of the structure.

4 - Is GreenSpec® Listed

GreenSpec® is the highly respected green products directory produced by BuildingGreen, Inc. The company does not charge for listings or for the review process, nor do they accept advertising. As their resources are totally subscription supported, they have complete editorial independence and integrity - providing information that can be trusted.

"GreenSpec is the best resource in my collection of sustainable product guides and I refer to it frequently for my own projects and when providing recommendations for others."

Rising Damp

5 - Provides a Drier, Healthier Indoor Environment

The Fastfoot® membrane prevents moisture from wicking up through the concrete footing into the home. This prevents mold and fungi that grow in damp environments and can cause severe respiratory infections and allergic reactions.

Concrete is 'hygroscopic', meaning ground moisture wicks up through the footing concrete and inside the building. Fastfoot® is a vapor barrier which prevents this wicking.
