Independent-Grade CQA Documentation & Field Testing Records

Every installation is executed under a written construction quality assurance plan aligned to GRI-GM13 and ASTM D6392, with conformance testing beginning before the first panel is deployed. Incoming rolls are checked against mill certificates and sampled for thickness, density and asperity height where textured liner is specified, and subgrade is formally accepted and signed off before deployment proceeds. Trial welds are run at the start of each shift, after every four-hour interval and on any change in ambient conditions or operator, with tensiometer peel and shear coupons tested to specification acceptance criteria and recorded against the weld machine, operator and temperature settings in use. All fusion seams receive 100% air pressure channel testing at the specified pressure and hold duration, extrusion seams and detail work receive 100% vacuum box testing, and destructive samples are cut at the frequency set by the CQA specification and retained for laboratory verification. Non-conformances are logged, capped or repaired, re-tested and closed out on the panel layout drawing, so the record shows not only what passed but what failed, what was done about it and who signed it off. The deliverable at handover is a bound as-built package - panel layout, seam log, trial weld register, destructive test results, repair register, material certificates and daily site records - in the form your CQA consultant, engineer of record or regulator expects to receive it.
