Install VB Series Products

Ground Surface Preparation : Aggregate Base

Select the suitable Barrier-Bac product (VB-250, 11 mil or VB-350, 16 mil) and ensure the installation surface is relatively smooth. Although Barrier-Bac products are extremely tough, installation is easier and more effective when done over a smooth base. It is optional to have a layer of granular fill under the Barrier-Bac.
