Installation and technical guidance
Design and procurement inputs
Specify thickness, material, required certification, laps, penetrations and protection against damage. Construction sheeting is not interchangeable with an engineered containment geomembrane.
Provide the product grade or performance specification, drawings or BOQ, quantities, site location and required date. We will define supply, delivery and any agreed installation and QA/QC responsibilities in the quotation.
Request a product-specific quotation →Installation and QA/QC
Check product identification, thickness documentation, placement, joints, penetrations and damage before concealment.
Use the current supplied-product procedure and the approved project inspection plan. Define responsibilities and acceptance criteria before installation.
