Geosynthetic clay lining (powder)

*Powder bentonite (D: 0.074mm) wrapped between a layer of woven/non-woven geotextile and a layer of non-woven geotextile.
*Faster expansion (about 6 times faster than particle en_gcl at the same unit weight) and improved hydraulic sealing performance.

characteristic

TMAT ® en_gcl (powder) is an improved product of granular en_gcl, which has the characteristics of fast response and good anti-seepage effect, especially suitable for water landscape waterproofing and anti-seepage.

The relationship between hydration time and permeability coefficient in the report
Particle en_gcl hydration time permeability coefficient (× 10-9cm/s) Powder en_gcl permeability coefficient (× 10-9cm/s)
1 hour 538.26 no leakage
2 hours 334.73 no leakage
24 hours 53.45 no leakage
48 hours 13.26 0.65
72 hours 9.59 0.50
96 hours 4.66 0.49
The particle size of bentonite is relatively large. When the surface encounters water, a waterproof film is formed to prevent water from entering the particles and delay the hydration expansion of bentonite. Meanwhile, due to the large particle size of bentonite, it needs to self expand to seal the voids, and its hydration requires a certain amount of time, which makes its early anti-seepage performance poor.

application
TMAT ® en_gcl (powder) is an extremely versatile clay lining product. In over a decade of successful installation, the scope of TMAT's application is almost unlimited:
Waste and contaminated soil cover
Landfill base liner
Gas seal and vapor seal
Surface water storage liner
Secondary containment vessel
Dams, canals, and waterways
Tailings containment
Groundwater protection
Adsorption barrier
Vertical barrier
waterproof
