Moisture & Durability

Moisture is the greatest threat to the durability of your home. Over time exposure to moisture can lead to corrosion of building components, insect habitation, wood rot and mold. Moisture can also affect indoor air quality and, without proper drainage, could lead to foundation failure.

It is essential that rainwater be diverted away from buildings. Gutters and downspouts are a critical line of defense against foundation problems. Absence of gutters can result in a range of issues from foundation wall failure to cracked foundations and wall joints.
Senox has concluded that the most critical element of optimal gutter performance is eliminating gutter debris. Therefore, we are developing products and methods that will provide solutions for long-term roof drainage and collection needs.

Building Moisture and Durability
U.S. Department of Housing and Urban Development
This project set out to develop a set of recommendation for future research on moisture problems in housing. The research recommendations were developed following a review and analysis of the extensive technical literature concerning the problems created by bulk water and excessive water vapor in houses, and the solutions to those problems.

"Working gutters and downspouts are a critical line of defense against foundation moisture problems in large parts of the country. Lack of gutters causes problems ranging from wet basements to foundation wall failure. Clogged downspouts or clogged gutters due to lack of maintenance result in overflows with similar consequences. Yet the International Residential Code has no requirements for installing gutters on pitched roofs, and no placement or sizing requirements for downspouts."

Healthy and Affordable Housing
Building Sciences Corporation
The fundamental principles of groundwater control are to keep rainwater away from the foundation wall perimeter and to drain groundwater with sub-grade perimeter drains before it gets to the foundation wall. This applies to slabs, crawlspaces and basements (see Figures 8a, 8b and 8c) regardless of whether they are newly constructed or undergoing rehabilitation.
