Testing
Testing of plastics in compliance with current standards
Mechanical testing
The quality of welded joints are of crucial importance when installing geomembrane structures. The quality of the adhesion of the welding surface is guaranteed by a number of measures:
Control of preparations and welding parameters before the start of the welding process.
Control during the welding process.
Visual and mechanical examination of the manufactured welds after the welding process.
