Composite decking is built to last — but it's not maintenance-free. Mauritius's tropical climate and coastal salt air create unique challenges for composite boards, especially in high-exposure resort and villa settings across Tamarin and the west coast.
Tamarin's villa density — particularly the IRS estates like Tamarina Golf Estate and surrounding resort properties — means composite decks are under constant stress from salt spray, UV exposure, high humidity, and thermal cycling.
Composite boards cup or warp because of uneven moisture absorption. In Tamarin's humid climate, improve drainage underneath, check fixings, and replace boards exceeding ¼-inch warping.
UV light bleaches composite pigments. Use oxygen-based cleaner, apply UV protectant, add permanent shade, or replace faded boards.
Fasteners loosen from thermal cycling. Use cordless drill with square-drive bit, tighten snug then back off ¼ turn. Replace corroded 316-grade stainless steel fasteners.
Shaded areas collect moisture. Clean with oxygen bleach (never chlorine), improve air circulation, and apply composite-safe algaecide annually.
Composite decks are lower-maintenance than timber, but they're not maintenance-free — especially in Tamarin's coastal, high-humidity climate. Early detection and timely repairs will extend your deck's life by years.
