Raging Rivers Waterpark — Lazy River Entrance Staircase

Mandan, ND
November 2022

Project Summary

November 2022 specialized cold-weather installation. Traveled to North Dakota because membrane company attempting lazy river lining in very cold months couldn't make staircase look right or stay correct in cold. Temperatures didn't get above 40°F with real feel in the 20s most days. Other installers couldn't make it look right because cold immediately tightened membrane after warm application, causing poor appearance once weather warmed. Created specialized station keeping material just warm enough to cure correctly. Result was great-looking staircase that maintained appearance in warm months. Also lined curved walls.
