Bentonite geosynthetic clay liner applied to the Artificial lake construction plan

Geosynthetic Clay Liners is a geosynthetic material specially used for Artificial lake water features, landfills, underground garages, pools, etc. to prevent seepage and leakage. How is the bentonite geosynthetic clay liner constructed when applied to Artificial lakes? The following is the specific plan for the application of bentonite geotechnical synthetic clay liner produced by our company to Artificial lakes.

The following is the list of contents:

• Preparation before construction

• Steps in the middle of construction

• Finishing after construction

Preparation before construction

Bentonite geosynthetic clay liner construction process is as follows: reinforced concrete substrate base water leakage management → base surface leveling, cleaning → construction preparation → waterproof blanket laying/hanging → lap joints closed → shake head closing, protection → repair of damage → finished product protection, the following a total of five steps.

1、Prepare more than 100m2 of flat open space for unloading and release cutting;

2、Preparing a small amount of water and a bucket of 40cm in diameter and 50cm in depth for the preparation of bentonite mastic;

3、Analyze the terrain conditions to be laid and arrange the construction sequence; measure the length and width of the Artificial lake, determine the material cutting scheme, then place the material and prepare for construction;

4、Laying of bentonite waterproofing blanket in blocks in the prescribed order and direction. The Geosynthetic Clay Liner’s flat lap, blanket, and blanket joints should be staggered, and should not form through joints. A waterproof blanket of the first cloth should be laid in the lowest part of the Artificial lake, the first cloth as the starting point to both sides of the extension of the laying;

5、The connection between the bentonite geosynthetic clay liner: the waterproof blanket in the length and width direction lap 25 ~ 30cm, should ensure that the joints are without folds and no debris.

Steps in the middle of construction

• Bentonite waterproofing blanket lap underneath the width of 10cm, 0.5cm thick strips of bentonite powder, lap in the middle of two layers of bentonite waterproofing blanket, external seams with bentonite mastic seal;

• Bentonite waterproof carpet and pipeline and structure detail parts of the processing: before laying waterproof carpet, first in the pipeline and structure detail construction 5mm thick bentonite mud or dry sprinkle bentonite; waterproof carpet laying after the external seam with bentonite mud sealing;

• Facade and slope when laying bentonite waterproof carpet, to avoid its sliding, available steel nails plus shims will be fixed, must do bentonite waterproof carpet firmly installed in the wall and the ground, nail hole parts need to be sealed with bentonite mud treatment. Bentonite blanket horizontal, vertical lap length of 300mm, lap evenly sprinkled with bentonite dry powder, the thickness of 5mm. Façade part of the wall in and Yang corner is made of rounded, lap length of 100mm, fixed with nails and bentonite mastic coating seal.

Finishing after construction

• Waterproof blanket paving is completed, and the naked eye is to see if there are broken parts or folds, whether there is a hollow drum or tight, if any, to adjust or repair. The waterproof blanket should be tightly fitted to the substrate as qualified;

• Waterproof blanket construction is completed that backfill silt and planting soil, followed by the Artificial lake filled with water so that the bentonite in the waterproof blanket at the same time expansion, the formation of a uniform gel waterproofing system.

We produce Geosynthetic Clay Liners by the high expansion of sodium bentonite filled in a special composite geotextile and non-woven fabric between the needle punching method, forming many small spaces so that the bentonite particles are limited in a movement when water in the limited space to form a uniform high-density gelling, effective prevention of water leakage, long time or changes in the surrounding environment will not occur aging or corrosion phenomenon.
