Water Infiltration Testing and Repair

Coit Tower
San Francisco, CA
Water leaks and water penetration are among the most frequent types of building failures, yet locating the source of water entry can be difficult without destructive investigations.

Interactive Resources offers the capability for on-site testing of water infiltration problems. Available for use in identifying entry points is a portable Water Infiltration Test Assembly, one of a limited number in use in California. This equipment enables the firm to quickly perform complex on-site technical investigations locating sources of water infiltration in accordance with American Society for Testing and Materials (ASTM) standards.

The test procedure involves the sealing of a room to devise a test chamber, and the creation of a vacuum within the chamber. Specially calibrated equipment for the manipulation of air and water pressure and wind velocity differentials is used while spraying water on the exterior building surfaces. With this equipment, hidden sources of leaks can be quickly identified and appropriate repairs designed.
