Vapor Barrier Concrete Screed System | FinCaps, FinStand, CoilStand & Base Plate Supports

Concrete Screed Support Systems for Vapor Barrier Slabs

MADE in USA

Fast setup. Accurate and repeatable elevation. Compatible with hand or laser setups. Designed for contractors who need speed without sacrificing flatness.

The MAKO Vapor Barrier Structural System is designed to provide stable elevation control when concrete slabs are poured over vapor barriers, poly sheeting, insulation, or other non-penetrating substrates. Traditional screed chairs and supports often rely on mounting structures driven into the subgrade, which is not possible when a vapor barrier must remain intact.

Best For: Vapor Barrier pours, Concrete overlays, Drains, Rail Critical, High FF/FL Floors, Tennis Courts, Gymnasims, Swimming Pools, Waterways, Performance concrete, Pan Decks, Sloped slabs, Tunnels, Super Thick Floors, Manufacturing plant slabs, Embankments, Bridge decks and infrastructure projects, Super flat floors requiring FF/FL compliance and more.
