Geo-Seal® EFC

Geo-Seal® EFC is a complete coating system specifically developed to mitigate vapor intrusion into existing structures. Typically composed of 10 mil primer (Geo-Seal® EFC PRIMER) and 20 mil coating (Geo-Seal® EFC), the system is applied to existing building concrete floors. Due to our specific formulation, it provides an extremely high-level chemical resistance not found in most common epoxy resin-based coatings. An epoxy floor coating will remove existing vapor intrusion pathways while also long-term providing vapor intrusion protection. The additional reasons for considering a vapor intrusion coating include:*Site concentrations are low, but additional vapor intrusion protection is desired*Augment and provide redundancy to an active sub-slab vapor collection system*Retire the operation of an active sub-slab vapor collection system while still maintaining vapor intrusion protection.*Eliminates the costly removal of the existing concrete slab.*A new building requiring a VIMS is being built and sections requiring the VIMS were built before the system could be installed, for example elevator pits.
