GCL is an update geosynthetic waterproof material made hongxiang chemical fibre group engineering material Co., ltd  with advanced international technology and equipment. It is composed of 3 levels. The upper level and the lower level are woven geotextile and non woven textile. The middle level is bentonite grains and filled in between the two levels after special processing. The bentonite grain in GCL made by this method does not flow in a fixed direction. It distributes evenly and forms waterproof layer, owning excellent waterproof effect. This GCL is a kind of new green waterproof materials, which are widely applied in many waterproof construction projects.

GCL of Hongxiang brand can be applied separately, or combined with high density polyethylene (HDPE). Our GCL combines the two advantages together, not only containing all the properties of geotextile materials, but also bearing of double waterproof property.


1. Environment friendly.

Hongxiang Chemical fibre group engineering material Co,.ltd is made of natural raw materials of sodium-bentonite.It is raw and natural materials,;aging and corrosion seldom happen. It can keep its quality and then it does not cause any injuries and pollution for human and the environment. It is not only waterproof, but also has good ventilation performance. It can stick up for the exchange of the ecological environment. It is a pure natural, new, green waterproof material.

2. Permanent waterproof, excellent performance

Natural sodium bentonite was formed billions of years ago.

Its waterproof properties are much more durable than that of the buildings. Sodium bentonite would transform to high density septum under hydro pressure. When The thickness is 3mm, the permeability is below a*10-11/sec(a=1~9), which equals to the density of 100 times of the clay with 30 mm thickness. Water retention performance is evident.

3. Easy to construct

Bentonite powder, nails and washers are enough for connection and fixation. Construction is not constrained by weather conditions and it could be taken under cold or wet conditions. Bentonite powder is spread on overlap point. When water comes, GCL would be overlapped automatically. It is so far the only material that starts the waterproof effect by water in the world. It is not necessary to take additional examination when the construction is completed. The repair works are easy in case of waterproof defects. Among the existing waterproof materials, GCLs construction period is the shortest and its operation is the easiest. It has an eminent effect on shortening the construction period as well as saving the cost.

4. Strong Self-Restore Capacity

The integration between waterproof material and its target enables GCL a 20~28 times swelling volume. Even if concrete structure trembles or subsides, the bentonite in GCL would restore the crack of 2mm or below on the concrete structure immediately. Even if the diameter of perforation reaches 30 mm, the restoration will be finished within 15 days completely.

Construction Instruction:

1.Before paving, make sure the base plane is even; tamp the ground and clear up the debris in case that GCL be punctured by sharp articles, which in turn affect the waterproof effect. Accumulated water shall be drained in the mean time to avoid GCL being soaked by water.

2.When paving the GCL, determine the direction and position. GCL shall be paved on the base plane according to the direction in proper order and shall be fixed by nails and washers. Nail length is 3040 mm. The distance between two nails is about 400 mm. When paving is undertaken on vertical plane or slopping surface, additional nails and washers shall be added accordingly in order to avoid sliding. Nails are used to fix the edges of overlapping part of GCL; besides, a number of nails shall be added and fixed evenly on the whole GCL according to the flatness. Make sure that GCL is fixed stably on ground and wall.

3.Lap joint. Lap width is between 200 and 250 mm. A bentonite cube with 100mm width and 10 mm height shall be spread between upper and low ends. The joint shall be occluded by bentonite mud. Bentonite cream (bentonite is mixed with water in a ratio of 13. After stirring evenly, bentonite cream forms) is applied for occlusion on slope or special point. Make sure there is no drape, miscellaneous soil or other materials on the joint.

4.Special paving.

5.After paving, clean up works shall be done. Sand and cement mortar shall be scattered on GCL so as to form a preventive layer. After tamping evenly, the whole paving process is completed.

The  natural sodium bentonite such as water-swelling, water proof, viscosity, plasticity, compaction, stability, lubricity and cation exchange, etc are examined to be in the leading position in Asia.
