Questions about this product
What is GB-Granules?
GB-Granules is granular activated bentonite from GEOBENT for waterproofing, barriers and soil stabilisation. The product page lists foundations, underground structures and tunnels.
What does the GEOBENT data sheet say about GB-Granules?
The GB-Granules table on the product page lists montmorillonite 65–85%, moisture 10–14%, fraction 0.1–5.0 mm, free swelling index min. 25 mm/2 g, filtrate volume max 18 ml, pH 10, methylene blue adsorption min. 400 mg/g and water absorption min. 600%. These are the values on the GEOBENT product page.
How is bentonite granule used for sealing in the industry?
Typical approaches are placing dry bentonite granule as a barrier that swells when wetted and tightens the joint, and using it around foundations and in ground barriers. Industry publications often cite roughly 5–15 kg/m² for soil sealing, higher on permeable ground. These are typical industry recommendations, not a GEOBENT guarantee. The choice depends on the conditions — contact GEOBENT and we will prepare a recommendation and a free sample. This is not a GB-Granules dose set by GEOBENT.
How does GEOBENT pack GB-Granules?
