Just 4 square feet can cost you.
This is a photograph of an actual extrusion weld salvaged from a construction site. We noted 14 different problems, each of which could lead to containment failure, in an area that is less than 2 feet x 2 feet.
Imagine the potential liability (and repair costs) if this caused a major containment failure on your project.

Heat Damage From Tacking Process
Weld Is Too Thin
