Liners can be installed during winter, but the process requires extra care to ensure good performance. Cold temperatures can make some materials stiffer, so crews often aim for days when the liner can warm slightly in the sun before positioning it. RPE liners are often preferred in these situations because they stay more workable in low temperatures and are lighter to handle.
The main considerations are keeping snow and ice off the subgrade, making sure the ground is properly compacted, and avoiding sharp frozen clods that could create pressure points. When these conditions are managed, winter installations can be successful and provide the same long-term protection as those done in warmer seasons.
