Roboliner® and the new Roboliner® VI

RoboLiner Construction siteIntroducing the lowest perm, highest chemical resistant liner for vapor intrusion, Roboliner® VI.

Roboliner® VI is the first EVOH/polyurea multilayered membrane developed specifically for Brownfields and Vapor Intrusion Sites. This is the first commercially available liner that combines the unmatched chemical resistance and Diffusion Coefficients of EVOH and the physical properties and low perm rates of a pure polyurea. This combination of materials is more chemical resistant and more construction friendly than any other liner on the market.

Because it is manufactured in a controlled environment the QA/QC is conducted at the plant and it arrives fully cured and ready to resist chemicals, unlike field sprayed liners. Another key advantage is its rapid installation. Any liner installer, consultant,or GC, understand that rapid installation is key to keeping a construction project on budget.
