Installing a Flexible Pond Liner: Step-by-Step Construction Guide

Edge Prep: Cut 45 cm (18″) turf strip around perimeter. Liner overlaps this + edging (bricks, slabs).
Excavation: Dig hole; shape shelves as you go (min 30 cm / 12″ wide for planted baskets). Slopes 70°–0° acceptable.
Soft Soil Reinforcement: Build brick/block back wall on top shelf, mortar-secured. Line back with bricks.
Level Shelves: Check with spirit level—critical for container placement. Bottom level optional.
Underlay: 5 cm (2″) damp sand, or proprietary felt/old carpet. Remove sharp stones first. Cover reinforced corners.
Liner Installation: Mold into excavation, smoothing creases. Fill shallow area first; smooth folds as water rises.
Final Trim: Fill completely. Trim liner leaving generous overlap for edging coverage.
