Impermeable geomembrane has good mechanical properties, elongation at break is greater than or equal to 600%, so it has strong deformation resistance, good puncture resistance and plant root resistance
. 
In some factories, the foundation laying can also play the role of moisture-proof, the width of the product is generally 6 meters, can also be customized according to customer size
. 
The following geomembrane manufacturers on the geomembrane construction problems and precautions to share with you, hope to help friends
. 
The anti-seepage geomembrane will be strictly inspected by the quality inspector before leaving the factory, and the thickness and mechanical indexes will be checked
.
The products are allowed to leave the factory after passing the inspection
.
But the anti-seepage effect of geomembrane has a lot to do with the construction
.
If we want to achieve good anti-seepage effect, we’d better appoint professional construction masters to complete it
.
The construction of anti-seepage geomembrane should pay attention to the following points: 1
.
The repair of the foundation should meet the basic laying requirements, that is, the flatness is good, there are no cracks, there are no tree roots, bricks, broken glass and other objects, and the compaction of the foundation is good
.
The slope surface should be smooth without large soil lumps
.
2
.
Temperature requirements during construction
.
It is not recommended to carry out construction under severe cold conditions, because any object has the characteristics of thermal expansion and cold contraction
.
The temperature of geomembrane welding under cold conditions should be appropriately increased
.
3
.
The anti-seepage effect of geomembrane is also closely related to welding, so the number of welds should be reduced as much as possible
.
When welding impermeable geomembrane, there must be a stable power supply, otherwise the welding machine will stop after power failure, and it is easy to weld holes in geomembrane
.
Therefore, construction should be avoided in rainy days or places with water as far as possible
.
Before welding, the welder should be heated in advance
.
When the temperature reaches, welding should be carried out
.
If there is dew, oil, dust and other dirt at the joints, towel should be used to wipe them clean before welding
.
For those who are not familiar with the operation process, a piece of geomembrane can be cut off for trial welding
.
T-joints and cross joints can be reduced as much as possible in the welding process
.
If it is unavoidable, extrusion welding can be used for joint repair
