Anchorage and splicing method of anti-seepage geomembrane

The simple way is to observe the appearance of the membrane without penetration. For example, if the surface is smooth and free of particles, it is basically judged that the waterproof layer is actually good. This does not mean that the impermeable film containing particles on the surface must have a poor practical effect of impermeable.
The actual effect of the waterproof layer film must be tested according to professional waterproof layer film testing instruments to clarify the actual effect of the waterproof layer film.
In order to better ensure the construction quality of the anti-seepage geomembrane, when selecting the anti-seepage geomembrane, the appropriate overall width of the anti-seepage geomembrane should be selected according to the specific conditions of the construction site, in order to avoid the total number of welding anti-seepage geomembrane. First, it can reduce the workload. Secondly, there is a guarantee for the actual effect of the waterproof layer of the waterproof layer film.
Because the manufacturers of waterproofing film on the market are mixed, some of them are of low quality, which seriously interferes with the normal market order. Some consumers are artificial, and the price of impermeable geomembrane is very high, which is also a type of prejudice. When selecting the anti-seepage geomembrane, the main effect of the waterproof layer of the anti-seepage geomembrane is mainly selected. High-quality anti-seepage geomembrane is not a star or half of poor quality.

In order to better ensure the construction quality of the waterproof layer of the anti-seepage geomembrane, the anti-seepage geomembrane must be prepared before construction.



1. Formulate the overall construction schedule.
Make on-site paving plans, clarify the specific methods of anchoring and splicing anti-seepage geomembrane, and make full preparations.
2. Clean the paving site.
If the foundation is used as a support layer for the anti-seepage geomembrane, make sure that the foundation is firm and flat. Remove all debris, such as sharp stones and debris, and use a roller mill to compact the foundation. If necessary, anti-seepage geomembrane pads or geotextiles should be provided for protection.
3. Concrete structures and other structures that are in direct contact with the anti-seepage geomembrane should ensure that there are no sharp edges in the contact area to prevent damage when laying the anti-seepage geomembrane.
4. Anchor slot structure.
If it is necessary to anchor the anti-seepage geomembrane, before laying the anti-seepage geomembrane, the anchor trench should be excavated and the floating mud and debris in the trench should be cleaned to ensure its stability.
