Reservoir & Dam Lining
Water-storage lining for reservoirs, farm dams and process-water facilities. Geosynthetics Africa coordinates product supply, delivery, installation and documented QA/QC to the agreed project scope. Send your BOQ, drawings and project location for a proposal matched to the specified system.
System Overview
Water-storage lining for reservoirs, farm dams and process-water facilities requires a system selected for the site and its operating conditions. The geomembrane, protection layer and termination details are selected for the specific reservoir. Drinking-water suitability must be confirmed for the exact product and approval, not inferred from the polymer type.
The starting point is the approved design and the project information: water use, operating levels, foundation condition, exposed or covered service, penetrations, anchorage and any potable-water approval required. We review the material schedule and specification with the project team before confirming products and quantities.
Supply and delivery are planned around the destination, access and construction programme. Product identity, available documentation, packing and route requirements are confirmed in the proposal; stock and mobilisation commitments are project-specific.
Installation and QA/QC are defined in the agreed scope, with inspection hold points and records established before work starts. Independent CQA or specialist testing is included where specified and appointed for the project.
Design Inputs for Reservoir & Dam Lining
Confirm the design inputs: water use, operating levels, foundation condition, exposed or covered service, penetrations, anchorage and any potable-water approval required. The project designer sets the system arrangement and acceptance criteria.
The geomembrane, protection layer and termination details are selected for the specific reservoir. Drinking-water suitability must be confirmed for the exact product and approval, not inferred from the polymer type.
Confirm interfaces, joints, connections and transitions on the drawings. Adjacent products must be compatible with the selected system; proposed substitutions require designer approval.
Use current manufacturer data for the exact grade and the relevant service conditions. Generic thicknesses, tensile ratings or service-life claims do not establish suitability for every project.
Reservoir & Dam Lining Installation & Handover
Before installation, confirm the product and grade, accept the work area and inspect delivered material. Establish storage, handling, layout and protection requirements using the approved method and manufacturer guidance.
For applicable geomembrane seams, the QA/QC plan identifies air-channel testing (ASTM D5820), vacuum-chamber evaluation (ASTM D5641) and destructive peel/shear testing (ASTM D6392) as appropriate to the material and seam. Test settings, sampling and acceptance criteria come from the approved specification; electrical leak testing is a separate, specified method.
Record installation checks, test results where required, repairs and hold-point releases. Protect completed work until acceptance and compile the agreed traceability and handover records.
Reservoir & Dam Lining QA/QC
Approved Design & QA/QC Plan
Confirm the approved drawings, product schedule, method and inspection hold points. Testing and acceptance criteria are agreed before installation.
Product Identity & Traceability
Check manufacturer, product grade, roll or unit identification and the required documentation against the order and approved submittals. Record damage or discrepancies for resolution.
Work-Area Acceptance
Inspect the prepared work area, levels and interfaces against the specified acceptance criteria before placing the system. Required geotechnical verification is completed by the appointed party.
Installation Inspection
For applicable geomembrane seams, the QA/QC plan identifies air-channel testing (ASTM D5820), vacuum-chamber evaluation (ASTM D5641) and destructive peel/shear testing (ASTM D6392) as appropriate to the material and seam. Test settings, sampling and acceptance criteria come from the approved specification; electrical leak testing is a separate, specified method.
Specified Testing
Apply the test methods and frequencies specified for this system. Specialist or independent testing is provided where required by the project appointment; a method suitable for one material is not automatically suitable for another.
Repairs & Non-Conformance
Record non-conformances, agreed corrective work and reinspection. Keep the product or installation under control until the specified acceptance process is complete.
Handover Records
Compile the agreed product identification, inspection records, applicable test results, repairs and as-built information for project handover.
