CONCURE SYSTEMS Vapor Barrier +PLUS+ is a topically applied system designed to stop floor coverings from de-bonding due to moisture. The system is water based and designed for fast track installations. The primary use of Concure Systems Vapor Barrier +PLUS+ is for waterproofing below grade slabs, on-grade slabs, and elevated deck slabs.

This system stops hydrostatic pressure, capillary action and moisture migration. It also creates a negative and positive side barrier. This product is compatible with all adhesives, self-levelers and floor coverings.

Vapor Barrier +PLUS+ is a silicate sealer that penetrates into the concrete slab. A reaction occurs between the lime and excess Portland cement, which is always present, and forms Calcium Silicate Hydrate (CSH). This process will encapsulate the moisture to create a permanent break in the capillaries of the concrete, stopping all moisture related problems caused by moisture vapor emissions out of or through the slab.

This system is designed to stop moisture problems measured at all levels intolerant to the installation of flooring as recommended by flooring manufacturers.


Either an ASTM D-5084 test and/or ASTM D-4263 test done by flooring contractor is required and the results of this test must be registered with Concure Systems Corporation. (See Concure for further details)
