Estimating and procurement guide | For farmers, contractors and procurement teams Geomembrane pond installation cost is not limited to the sheet price per square metre. Ground preparation, actual lining area, sheet specifications, installation and welding, inlet and outlet details, quality control and transport all belong in the estimate. Two offers with the same sheet price can therefore have different final costs. This guide helps define the scope before ordering and compare supplier and installer proposals on a consistent basis. Final cost depends on drawings, site conditions and approved project specifications. Quick answer: For an initial estimate, prepare the project

Quantity take-off guide | For farmers and contractors Pond floor area alone is insufficient for estimating geomembrane quantity. Sloping walls, perimeter anchorage, seams and roll layout affect the order. Before purchasing, distinguish the net lining area from the sheet purchase quantity and the installation payment basis. This article illustrates the geometry of a regular rectangular pond. Irregular shapes require a survey and take-off from a geometric model. 1. Which dimensions should be measured? Record floor length and width, vertical depth, top length and width, and the slope of each wall in one unit, preferably metres. State whether drawing dimensions

Site handover guide | For contractors, inspectors and project owners Inspect and document subgrade preparation before deploying a geomembrane. The sheet does not correct unsuitable ground conditions. This checklist clarifies responsibilities, areas requiring correction and handover records. Compaction values, slopes, protection layers and drainage details must come from the approved project design. 1. Check reference documents before mobilization Provide the installation team with the latest plans, sections, product specifications and anchorage details. Record discrepancies between drawings and actual conditions before installation begins. A verbal change to slope or outlet location may change quantities, panel arrangements and the installation schedule.
