Bentonite API Grade

API 13A Section 9 Bentonite – High Yield Sodium Bentonite in Mathura

Filtron Envirotech (India) is a leading Manufacturer, Exporter & Supplier of API Grade Bentonite for drilling, piling, and construction applications across Mathura. From the Mathura industrial foundation works to the region's new high-rise developments in Mathura City, Vrindavan, and Kosi Kalan, our API grade bentonite ensures superior drilling performance and cost-effective operations in Mathura.

API Grade Bentonite is a premium quality sodium montmorillonite clay used as a viscosifier, fluid loss control agent, and lubricant in drilling fluids. In Mathura, our bentonite is extensively used for diaphragm wall construction, for pile foundations in commercial and industrial complexes at Mathura Refinery, Kosi Kalan, and Vrindavan, for water well drilling in rural Mathura's agricultural areas, and for cementitious grouts in the region's infrastructure projects. Our bentonite is also used in the foundry industry in the Mathura area. (Keywords: API bentonite, drilling grade clay, piling bentonite, foundation chemicals Mathura)

This bentonite grade rapidly disperses in fresh water, building a stable gel structure that keeps cuttings in suspension while the mud is static and flows easily when circulated. The fine particle size ensures deep filtration control, creating a smooth, low‑permeability wall cake that minimizes differential sticking. Beyond drilling, it serves in slurry trenching, diaphragm walls, and as a low‑permeability sealant for ponds and landfills. Its API compliance guarantees consistent performance across batches.

Advantages:

  • High yield & rapid hydration – Reaches target viscosity quickly with less material.
  • Superior cutting suspension – Prevents settling in deviated and horizontal sections.
  • Low API fluid loss – Builds a thin, tough filter cake that seals porous zones.
  • Excellent borehole stabilization – Reduces washouts and cavings in unconsolidated formations.
  • Versatile mixing – Can be pre‑hydrated or added directly through hopper into fresh water.
