FAQ

Answers to common technical and commercial questions.

How wide and thickness can you make a single panel?

We accept custom dimensions for any size. Common orders typically have thicknesses of 40–60 mil, with sizes such as 10x10ft, 15x15ft, 20x20ft, 30x30ft, 50x50ft and any size

Can you provide EPDM installation accessories?

Yes, we provide butyl tape and EPDM seam tape for bonding and repairs. Our products do not require primer treatment.

What thickness should I choose?

1.0–1.14 mm (≈40–45 mil) for decorative ponds with smooth subgrade.
1.5–2.0 mm (≈60–80 mil) for deeper water, rocky subgrade, or commercial use.
Tip: Always use non-woven underlayment to protect from puncture.

How long does EPDM last outdoors?

EPDM is renowned for its multi-decade weathering resistance. Service life depends on UV exposure, water chemistry, mechanical protection, and installation quality. Pro Tip: Protect exposed edges from direct sun and physical damage for long-lasting performance.

Is EPDM safe for koi and aquatic plants?

Yes, pond-grade EPDM is safe for fish and plant life. We also have MSDS certification to guarantee fish safety. Make sure to rinse thoroughly before introducing fish. Avoid using harsh chemicals that could affect water quality.

How reliable are the seams?

Factory-welded seams and field seams using EPDM seam tape are both highly reliable when installed correctly. Quick Tip: Keep surfaces dry, clean, roll firmly, and conduct peel tests at seam starts/stops.

Do I need underlayment?

Yes, non-woven geotextile underlayment (typically 8–12 oz/yd²) is recommended above soil or rock to protect the liner from punctures and to help distribute loads.

Can I install EPDM in cold weather?

Yes, EPDM remains flexible in low temperatures. Ensure adhesives and primers stay within their recommended temperature range and warm up the seam area if necessary.

How do I repair damage or leaks?

Clean and dry the damaged area, apply EPDM seam tape, then use a compatible EPDM patch or cover strip. Pro Tip: Round patch corners, roll firmly, and perform a peel test.

Are pipe penetrations and bottom drains supported?

Yes, we provide pre-molded EPDM pipe boots and compatible sealants. Finish with a cover strip if specified.

Does EPDM withstand chemicals, chlorine, or algae treatments?

Common pond treatments are generally compatible. Avoid petroleum solvents and strong oxidizers. For chlorinated systems, maintain levels within normal ranges and avoid shock dosing on the liner.

What are the lead times and shipping options?

Lead times depend on size and customization. We offer EXW/FOB/CIF/DDP terms and optimize palletization for container loading.

Can you customize packaging and branding?

Yes, we can customize cartons, paperboard cores, packaging, logos, and barcodes.

What are the minimum order quantities (MOQ)?

MOQs vary depending on thickness and width. Let us know your target sizes and we’ll advise on the most economical run length.

How should I store and handle the rolls?

Store rolls in their original packaging, out of direct sunlight, on level pallets. Avoid sharp objects during handling.
