What do you need to prevent damage pool walls and liner as my above ground cover has collapsed into from weight of snow ice?

Ensure the pool cover is properly installed and maintained. Make sure the cover is made of a durable, waterproof material that can handle the weight of heavy snow and rain. Check for any tears or holes in the cover and repair any damage immediately. Inspect the cover and supports regularly for any signs of damage or weakening, especially after heavy snow or rain.

Install interior support system: Install a support system inside the pool to help bear the weight of the snow load and prevent the pool walls from bulging. You can use a specially designed pool pole system or create a support structure using strong wooden beams or metal poles.

Install vertical support posts. Install vertical support posts around the pool's perimeter to reinforce the walls and help distribute the weight of the snow and ice more evenly. These posts can be made from sturdy materials such as wood, metal, or PVC pipes.

Remove snow and ice from cover. Regularly remove snow and ice from pool cover. Use a soft-bristled brush to gently sweep the snow and ice rather than shoveling or using sharp objects, which could damage the cover. To prevent the accumulation of snow, consider using a snow rake or push broom.

Shovel snow around the perimeter. To reduce lateral pressure and the amount of water weighing down the pool cover, clear the snow away from the pool walls. Be careful not to hit or damage the walls or liner when clearing the snow.

Use a sump pump or bilge pump. If the pool cover is significantly sagging, you can use a pump to remove the water from the cover and reduce its weight. Make sure to drain the water away from the pool area.

Cover Pool with Safety Cover. Invest in a sturdy winter pool cover made from a tightly woven material to protect your pool from winter hazards like snow and debris.

By taking these precautionary measures, you can protect your above-ground pool from damage caused by heavy snow and ice. Be proactive in monitoring the pool cover and addressing any issues as they arise to ensure your pool's longevity.
