Single-sided texture grips the subgrade while the smooth top face lets waste or cover material slide and settle. Double-sided texture is used on slopes of 3:1 or steeper, where the liner must interlock with the subgrade below and the cover soil, geonet or geotextile above. Send us your slope design and we will confirm which face build-up fits.

Standard textured rolls carry a texture height of at least 0.40 mm (16 mil), measured per ASTM D7466. For severe gradients such as 2:1 slopes, our lines can be calibrated to 0.40 mm (16 mil) and above. The guaranteed value is written into the technical data sheet for your order.

Our textured range runs from 1.0 mm to 3.0 mm (40-120 mil). The US EPA Subtitle D benchmark for municipal solid waste landfill base liners is typically 1.5 mm (60 mil). Abrasive mining operations and deep reservoirs usually specify 2.0 mm or higher. Final thickness depends on hydraulic head and subgrade puncture risk.

Trial orders start from 1-3 tons for regular specifications. For export shipments, a full container usually gives a better cost per square meter. Custom texture heights or roll sizes may need a larger minimum.

Standard products are usually produced within 7-15 days after the specification and deposit are confirmed. Custom orders or peak-season schedules typically take 15-25 days. We confirm the delivery date before mass production starts.

Yes. Every batch is tested in our own in-house laboratory, and a technical data sheet is provided for engineering submittals. Free physical samples can be shipped to your office or laboratory, and third-party inspection by BTTG or TRI Environmental can be arranged before loading.
