Solving Sunken Pool Decks, Driveways & Walkways on Maui, Big Island & Kauai
On Neighbor Islands, tearing out and pouring new concrete is especially expensive due to high island ready-mix prices and demolition disposal fees. High-density polyurethane injection lifts sunken resort and residential pool decks, driveways, and commercial sidewalks in Kahului, Kihei, Wailea, Kona, Waikoloa, Hilo, Lihue, and Poipu in hours with zero concrete tear-out.
Post-and-Pier & Crawl Space Solutions for Wet Valley & Upcountry Homes
Homes in high-rainfall zones like Hilo, Puna, Waimea, Upcountry Maui, Wailuku, Kapaa, and Hanalei frequently suffer from damp crawl spaces, rotting wood joists, and sinking concrete 'tofu block' piers. Installing galvanized adjustable steel support posts and a 20-mil vapor barrier permanently stabilizes sagging floors and blocks ground moisture.
