Yes. GEOBENT produces GB-Litter under a private label or to a customer specification: any fraction, plus colour and scent. Private-label packs are 5 kg, 10 kg and 25 kg bags, as well as 1 t big-bags and bulk.

Typical bentonite litter clumps when it meets moisture and absorbs liquid, which makes used clumps easier to remove. 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 also applies to GB-Litter raw material from GEOBENT.

A typical industry recommendation is a bentonite litter layer 5–8 cm deep. 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. GEOBENT supplies GB-Litter and does not set a single fill depth.

Typical practice is to remove clumps daily and replace the whole tray about every 2–4 weeks for one cat, more often with more cats. 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.

No. Typical industry advice is not to flush used bentonite litter, including litter made from GB-Litter. Dispose of it with waste according to local rules. GEOBENT does not give another disposal method.

Dust from bentonite litter depends on the fraction and how it is made. GEOBENT sets the GB-Litter fraction to the customer's specification and does not publish a single dust level. 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.

Order GB-Litter by email at info@geobent.pl. Questions: +48 573 588 382. The minimum order is one full truck, lead time is from 2 weeks after the order is received, and delivery is across Europe and for export. GEOBENT samples are always free.

GB-Granules is granular activated bentonite from GEOBENT for waterproofing, barriers and soil stabilisation. The product page lists foundations, underground structures and tunnels.

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.

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.

GEOBENT points GB-Granules to waterproofing foundations, underground structures and tunnels, and to soil stabilisation and limiting deformation. The barrier layout depends on the project. A GB-Granules sample is free: info@geobent.pl, +48 573 588 382.

The GB-Granules page lists 25 kg bags or 1 t big-bags. GEOBENT also ships bentonite in bulk. Delivery: Europe and export. The minimum order is one full truck.

In industry practice, bentonite granule in a confined space swells when it meets water and tightens the barrier. 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. GEOBENT does not offer one universal guarantee of how GB-Granules will behave in every soil.

GB-Form is activated bentonite powder from GEOBENT for foundry moulding sands, enriched with sodium cation. It is for stable moulds and castings. It is not a drilling-fluid product — GEOBENT supplies GB-Drill for that.

The GB-Form table lists, among other values, montmorillonite min. 80%, moisture 8–10%, swelling index min. 17 cm³/2 g, wet compressive strength 0.9–0.95 MPa and permeability 240 JP. The full table is on the GB-Form page. These are the GEOBENT sheet values.

GB-Form is supplied in 25 kg bags or 1 t big-bags. GEOBENT also ships bentonite in bulk. Delivery: Europe and export. The minimum order is one full truck.

GB-Soil is a bentonite soil additive from GEOBENT. The product page describes improved soil structure, moisture retention and fertility. GEOBENT does not publish a single field dose for GB-Soil.

Typical practice is to set the bentonite dose from a soil test, soil type and crop, not from one fixed number. 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 applies to GB-Soil.

GB-Feed Additive is a bentonite feed additive from GEOBENT. The product page describes support for digestion, toxin binding and feed use. GEOBENT does not publish an inclusion rate for GB-Feed Additive. Feed-additive rules depend on the country and the species.

In industry practice the share of bentonite in feed is set by species, purpose and local rules, usually with a nutritionist. 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. GEOBENT does not state its own GB-Feed Additive dose.

Order GB-Soil and GB-Feed Additive by email at info@geobent.pl. Questions: +48 573 588 382. The minimum order is one full truck, shipment is in bulk, 25 kg bags or 1 t big-bags, lead time is from 2 weeks, and delivery is across Europe and for export. Samples are always free.

GB-Sorb is bentonite from GEOBENT for filtering and purifying wine, beer, water, oils and juices. The product page describes removal of suspended matter and improved clarity. The full parameter table is on the GB-Sorb page.

In the industry, especially for wine, the bentonite dose is set by a laboratory trial on that batch. Published ranges are often roughly 20–100 g/hl and depend on the liquid. 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-Sorb dose published by GEOBENT.

The GB-Sorb page lists 25 kg bags or 1 t big-bags. GEOBENT also ships bentonite in bulk. Delivery: Europe and export. The minimum order is one full truck.

GB-Drill is OCMA-grade drilling bentonite from GEOBENT for drilling fluids in the oil, gas and geotechnical industries. It can be mixed with polymers and other additives. Laboratory tests follow ISO 13500 / API Spec 13A / API RB 13B (22.5 g / 350 ml).

The English GB-Drill sheet lists two grades: Normal (64 kg/m³ suspension) and Max (50 kg/m³ suspension). Shared values: montmorillonite min. ≥75%, moisture max ≤12%, pH 8–10, milling 80% less than 0.056 mm. Normal / Max: filtration max 16 / 15 cm³, apparent viscosity min. 32 / 35 mPas, plastic viscosity 8–10 / 9–11 mPas, yield ≥16 / ≥20 m³/t. The Polish sheet lists yield min. 18 / 22 m³/t. These are catalog values, not a field dose.

Typical practice for oil, gas and geotechnical drilling fluids: mix bentonite with water and often let it hydrate before adding polymers; hard water (calcium) is usually treated with soda ash because calcium limits swelling; viscosity is checked with a Marsh funnel and the concentration and additives are adjusted to the formation. A starting bentonite concentration in freshwater mud is often roughly 20–60 kg/m³ in industry practice. The 64 kg/m³ (Normal) and 50 kg/m³ (Max) suspensions on the GB-Drill sheet are the ISO 13500 / API test conditions, not a GEOBENT field dose. 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.
