Water Column Leak Testing

Haag Research & Testing is accredited by International Accreditation Service (IAS) to perform water column testing per ASTM D7281-07—Standard Test Method for Determining Water Migration Resistance Through Roof Membranes.

The water column test helps us determine the response and resistance of a particular material to water intrusion. Water column testing helps reveal the presence of leaks, indicating a fracture of the membrane.
