Drummondville Materials Testing Laboratory
In-house roof testing laboratory.
EXP’s roof testing laboratory was created in 2007 in Drummondville with the first test bench to measure the dynamic wind-uplift resistance of membrane roofing systems, in compliance with the development of the National Research Council of Canada (NRC).
Today, EXP has some of the most advanced experience and testing equipment in the world. The activities of the laboratory and the people associated to it are part of a broader spectrum encompassing consultation, expertise, training and assistance in the design of waterproofing and roofing structures along with architecture and control during the construction phase.
Our in-house laboratory is ISO IEC 17 025 and UL DAP certified.

Key Roofing Tests
- CSA A123.21
- Approximately 15 ASTM and ANSI/SPRI tests
- ANSI/SPRI tests on site to validate resistance
- Component evaluation and equivalence calculations
- Resistance evaluation for inverted roofs (gravel and/or concrete slab)
