GCL: 1. specification: 4kg/square meter to 5.5kg/square meter 2. clay component: natural sodium bentonite

GCL is composed of 3 layers, the upper layer is nonwoven geotextile, while the lower layer is woven geotextile, natural sodium bentonite fills the gap between geotextile layers. The application with natural sodium bentonite can enlong the using life of construction. Our GCL creates a new green and environmental building material.

We have two kinds of GCL. One is GCL without HDPE layer, the other is HDPE GCL. For GCL, it is widely used in landfill, lagoon, river bottom, basement and so on. For HDPE GCL, it is used in subway, basement, tunnel, underground and projects, salt water area in harsh environment.

Our product advantage:

Environment friendly

Our GCL is made of natural sodium bentonite, which contributes to good water proof quality, while causes no pollution to the environment. Its porosity guarantees the breath of biology.

Long-lasting waterproof performance

Natural sodium bentonite was formed billions of years ago. Its waterproof performance can last longer than building itself.

Easy application

Application of GCL is not constrained by weather. Connection and restore is easy to be finished.

Renzhong Advantage

Excellent raw material

We choose the best natural sodium bentonite to guarantee our good quality.

Competitive price

Our advanced production line, quality control and analysis system and convenient transportation to shanghai port help us the reduce cost, so that we can provide you competitive price.

First-class service and product

“Quality first, customer is god. ”is our doctrine. We will serve for our customer with all our effort.
