I live next to the river and every 5-10 years the river comes
up and floods the area. My deck can be underwater for
2-7 days. How will this hold up in those conditions?

Hi Kim! Thank you so much for reaching out and sharing your unique situation! TimberTech decking is designed to be highly moisture-resistant and won't rot or swell like traditional wood, even after heavy rain or short-term standing water. However, while our boards are tough, we don't recommend repeated or prolonged submersion, as it may affect the appearance or performance over time. Please feel free to give us a call at 877.275.2935 if you have any questions or need further assistance! - TimberTech Support
