No one is more knowledgeable and dedicated to stopping moisture vapor in its tracks, for floors and roof decks, than ISE Logik. ISE Logik has been dedicated to Lean Construction practices and the freedom from the costly dependence of concrete moisture testing as a standard building protocol since the company’s beginning. It is the #1 specialist in moisture vapor mitigation for new concrete slab construction or floor renovation over existing concrete. As a leader in educating the industry through webinars and articles, ISE Logik participates on various ASTM committees to establish standards and best practices in roofing, flooring, and waterproofing.

ISE Logik products are listed as Construction Products-Building Products Category in Division 3 (Concrete) and Division 9 (Finishes-Flooring) Select ISE Logik products also carry HPD and NSF labeling ISE Logik admixtures are formulated to stop moisture migration and warranted to 100% RH with no moisture testing required.
