As specified in the CTQ-M200 protocol, one (1) probe must be executed for each concrete slab elevation. For example, one (1) probe is done in the basement section and a second one in the presence of a garage section. If a section has been added or renovated (backfill replacement) after the construction of the original building, a probe must be executed in that section as well. The area or surface of the concrete floor is also considered in the price rating. In fact, if the area exceeds 2000 square feet, a second probe must be done in order to confirm the uniformity of the backfill underneath the concrete floor.
Note that other assays are available (microscopic examinations of thin sections, chemical analyses, etc.) if considered pertinent by the professional, for the assessment of the residual swelling potential of the backfill material.
Highly qualified geologists and engineers are always available in providing clear information concerning our surveys.
The work processes used in the surveys are done without any intermediaries and in compliance with the existing residential building survey protocol (CTQ-M200) developed by the Comité technique québécois d’étude des problèmes de gonflement associés à la pyrite (Québec technical comity for the study of pyrite associated swelling problems).
