Robelle Oval Pool Cover 12 x 18 ft — Heavy-Duty Winter Solid Cover with Winch & 4 ft Overlap

Robelle 12 x 18 ft Heavy Duty Super Oval Pool Cover is a solid, winter-grade polyethylene cover with an 8x8 scrim and four-foot overlap designed to protect above-ground oval pools through the off-season.

This solid winter cover combines heavier material and dense scrim to block water, snow, and debris while resisting wind and ice damage. Built by Robelle with over five decades of pool-cover experience, the 12 x 18 ft Super Oval includes a winch and cable for perimeter fastening, a black underside to block sunlight, and an imperial blue topside for a clean seasonal appearance. It’s engineered to float with the water surface and comes with a 10-year warranty for long-term use.

How does this cover protect my pool during winter?

The Robelle Super Oval is a non-permeable solid cover that prevents surface water, falling debris, and direct sunlight from entering your pool, reducing contamination and limiting algae growth during storage months. Its heavy-duty polyethylene and 8x8 scrim increase tear resistance and durability under snow loads and high winds.

• Solid, non-water-permeable construction keeps rain, leaves, and light out.
• 8 x 8 scrim woven into the fabric for higher tensile strength.
• Material weight of 2.36 oz/yd2 for added puncture and abrasion resistance.
• Black underside reduces sunlight penetration and helps limit algae.

Will this cover fit my 12 x 18 ft oval above-ground pool and how is it installed?

The cover is sized for a 12 x 18 ft oval pool with a four-foot overlap included, giving an overall cover dimension of about 16 x 22 ft to make installation easier. Robelle supplies a winch and cable that thread through grommets so you can tension the cover around the pool; for extra security, optional cover clips and wrap can be used where appropriate.

• Four-foot overlap simplifies drape and edge coverage around traditional top rails.
• Winch and cable included for perimeter securing through grommets.
• If top rails are unusually tall, choose the next size up to avoid stress on the cover.
• Use cover clips, wrap, or vinyl water weights (sold separately) for decked pools.

How durable is this cover compared to standard options?

Robelle’s Super Winter cover is built 18% heavier than common industry standards and uses a higher scrim count to extend lifespan under winter conditions. The combined material weight and scrim density are reliable indicators of long-term wear resistance, and the product is backed by a 10-year warranty for added buyer confidence.

• Constructed 18% heavier than typical covers for better longevity.
• 8 x 8 scrim helps prevent tearing from wind or snow movement.
• Material weight 2.36 oz/yd2 (approx. 80 g/m2) for robust performance.
• 10-year warranty supports the manufacturer’s durability claims.

What installation tips improve performance and safety?

Proper installation keeps the cover floating loosely on the water and avoids excess stress on seams and grommets. Use the included winch and cable to tension the perimeter, add water weights on decks or use clips where needed, and consider an ice equalizer pillow (sold separately) in climates with heavy ice to reduce direct pressure on the cover.

• Ensure the cover can float without tight stretching—go up one size if unsure.
• Run the winch cable through all perimeter grommets for correct tensioning.
• Place vinyl water weights on top of the cover where it rests on decks.
• Use an ice equalizer pillow in freeze-thaw regions to protect the cover.

Who is this for: The Robelle 12 x 18 ft Heavy Duty Super Oval Pool Cover is for above-ground pool owners seeking a durable, solid winter cover that blocks water and debris and stands up to wind and snow. It’s suited to traditional oval pools with standard top rails, homeowners who want easy installation with included winch and cable, and anyone who values a longer warranty and heavier material for offseason protection.
