Prefabricated panels are unrolled, unfolded, positioned and seamed with automatic hot wedge welding machines, producing double tracks for air testing. The seaming speed is approx. 2‐3 m/min. With 1000 sqm panels a three man crew will install 2-3 panels per day including positioning and quality testing.

Installation steps

Installation stage 11. Excavation work. Slopes should be restricted to max. 45°. Stones, roots and debris are removed, and the surface should be compacted, and smooth. The bottom surface shall have a positive slope to provide gas/water drainage.	Installation stage 12. A geotextile ( 500 – 800 g/sqm) or a layer of sand, ( 3-5 cm), is applied.	3. The EPDM panel, sized according to site drawing, is supplied as a roll on a pallet. Each panel is marked with panel number, position and unfolding directions.	Installation stage 14. The panels are rolled out, unfolded and positioned. At sizes over 600 sqm:s a winch or fork lift is recommended. Normal panel size is 1000 sqm but sizes up to 3000 sqm:s have been used.
5. The panels are seamed with a dual hot wedge producing a seam with an air channel.	6. Each seam is tested with air pressure. Results are documented according to SealEco QAS.	7. The EPDM panels are placed in anchor trenches and backfilled as panel placement proceeds. Then the final beach design is constructed.
