When overlapping adjacent composite geomembranes, first expose the geotextile at the joints, sew adjacent geotextiles to the bottom layer, and then fit the welding edges of the two membrane layers together. The width of the flap is 150mm.
The most important feature of geomembrane as an anti-seepage material is that it has a good anti-seepage effect. Therefore, it is widely used for external waterproofing of dams, reservoirs and other projects. Moreover, the construction technology is simple, the requirements are not high, the cost is low, and the waterproof effect is good.
Pay attention to three points when paving geomembrane, which can increase the service life.
The construction of geomembrane connection includes connection, welding and vulcanization methods. The connection method used in specific engineering practice should be reasonably selected according to different anti-seepage requirements and the characteristics of the selected geomembrane.
Geomembrane is a flexible anti-seepage geosynthetic material, and the stability of the support layer below it is one of the keys to the safety of the anti-seepage geomembrane.
