Geogrid test items: what is the point of the joint point?
Because geomembrane or waterproof plate in the actual construction of the project often need to overlap, that is, the edge stitching, and then use a welding machine to weld into one, to prevent water penetration
The water penetration point of the lap joint is a testing project of geomembrane or waterproof board
The conventional test items of geogrid are tensile strength, elongation, and welding point peeling force.So it is not feasible for you to put the waterproof material on the geogrid.
