Barrier-Bac LD8 Granular Seaming Bentonite

Barrier-Bac LD8 Granular Seaming Bentonite

Barrier-Bac LD8 Granular Seaming Bentonite is used as a binder and sealer around clustered pipe penetrations through Barrier-Bac Vapor barrier membranes.

In the case of clustered pipe penetrations, many pipes are concentrated in a small area. To seal clustered pipes with traditional pipe boots one by one may not be time and cost efficient. Barrier-Bac LD8 Granular Seaming Bentonite offers a solution that can seal clustered pipe penetrations quickly and easily.

Applications

When hydrated, Barrier-Bac LD8 Granular Seaming Bentonite swells and forms an impervious seal around PVC and metallic pipes to assure water vapor moisture migration will not occur between the vapor barrier membrane and these penetrations.

Installation

Pour a layer approximately one inch thick of Barrier-Bac LD8 Granular Seaming Bentonite around pipe cluster penetrations, spreading bentonite granules onto the area to be sealed, with granules overlapping the vapor barrier for better seal.

Lightly hydrate bentonite granules with a light water spray, taking care not to displace bentonite. Pour concrete adjacent to bentonite sealed penetration area and carefully spread concrete over bentonite.

Availability

Barrier-Bac LD8 Granular Seaming Bentonite is packaged in 50 lb. Bags, 48 bags per pallet.
