Big Kahuna's Water & Adventure Park — Rapid Slides Membrane Installation

Destin, FL
January 2025

Project Summary

Main attraction membrane installation on three large concrete slides November 2024-January 2025. People ride tubes down high-speed slide system with many sharp humps and curves, wading areas, and feeding area at top. Extensive grinding to remove thick paint layers, then hundreds of linear feet of coping installation on both sides and between each wall dividing slides. All humps specially designed to not budge, sag or deform with no water weight and constant float impacts. Custom threaded drain ports installed through piping in floor of each flat section for easy off-season drainage. Eliminates annual painting and concrete crack filling.
