VB Products Installation Guidelines
IntePlus® IntePlus® xf film VB Products Installation Guidelines Step 1A: Ground Surface Preparation : Earth Base Barrier-Bac should be unrolled to completely cover the pour area. Seams and/or joints can be joined using either BB20T Seam Tape or with heat welding. The film should be overlapped six inches side-to-side and endto-end.
IntePlus® IntePlus® xf film VB Products Installation Guidelines Step 1B: 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.

This placement method will provide the needed protection from outside moisture following construction completion.
IntePlus® IntePlus® xf film VB Products Installation Guidelines Step 4A: Seal Penetrations - Round Penetrations All penetrations must be sealed with the Barrier-Bac and BB20T Seam Tape. For round pipe or posts, please seal penetrations with Pipe Boot. 18˝ – 1 – Measure a piece of Barrier-Bac Vapor Retarder membrane 18 inches in width and twice (two times) the circumference of the pipe. – 2 – Roll the measured piece of membrane in a roll form approximately the size of pipe.
IntePlus® IntePlus® xf film VB Products Installation Guidelines Step 4B: Seal Penetrations - Square Penetrations All penetrations must be sealed with the Barrier-Bac and BB20T Seam Tape.For square posts, please seal penetrations with Block Out Seaming Methods. Cut corners approximately half the height of Block Out -1- Vertical seam tape Cut a piece of Barrier-Bac Vapor Retarder Membrane twice the height and one and one-half the length of the perimeter of the Block Out.

Patch all damaged areas with Barrier-Bac and Seam Tape prior to concrete pouring. Concrete may be poured directly onto Barrier-Bac VB-250 (11 mil) and VB-350(16 mil). However, a sand or gravel cover is preferred. It is used at the discretion of the architect or in compliance with local building and regulatory codes.
