1, before laying geomembrane should be by the civil engineering corresponding qualified acceptance documents. 2, geomembrane cutting before, should be accurate measurement of its size, and then according to the actual cutting, generally should not be cut according to the size of the drawing, should be numbered piece by piece, detailed records in the special form.

1, before laying geomembrane should be by the civil engineering corresponding qualified acceptance documents.
2, geomembrane cutting before, should be accurate measurement of its size, and then according to the actual cutting, generally should not be cut according to the size of the drawing, should be numbered piece by piece, detailed records in the special form.
3, laying geomembrane should strive to weld less, under the premise of quality assurance, try to save raw materials. At the same time, it is also easy to ensure quality.
4, membrane and membrane joints between the lap width is generally not less than 10cm, usually so that the weld alignment direction parallel to the slope, that is, along the slope direction.
5, usually in the corner and deformed lots, should be the seam length as short as possible. In addition to special requirements, in the slope greater than 1:6 slope from the top slope or stress concentration area within 1.5 meters, as far as possible, do not set up welded seams.
6, geomembrane in the laying, should avoid artificial folds, when the temperature is low, should try to pull tight, paving.
7, geomembrane laying is completed, should minimize walking on the membrane surface, moving tools, etc., wherever the impermeable membrane can cause harm to the object, should not be placed on the membrane or carry walking on the membrane, so as not to cause accidental damage to the membrane.
It is recommended that the project pay attention to the following links:
① composite geomembrane welded as a finished product, first do the bottom of the lake mortar protective layer.
② bridge foundation waterproofing, the use of steel through the membrane welding method, with mortar protective layer to prevent welding caused by the quality of hidden problems.
③ composite geomembrane and wall adhesion, to prevent the emergence of large-scale hollow drum.
