Water column testing helps us determine the response and resistance of a particular material to water intrusion. Water column testing helps reveal the presence of leaks due to fractures or holes in the membrane.

Haag  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.
