What are the best joinery methods for teak wood outdoor trash cans to prevent water pooling?

Teak wood remains the premier choice for outdoor trash cans due to its natural weather resistance and durability. However, proper joinery methods are crucial to prevent water pooling and ensure longevity. The mortise and tenon joint stands as the gold standard, providing exceptional strength while allowing for natural wood movement. For optimal drainage, incorporate slight gaps (approximately 2-3mm) in bottom panel joinery using groove and tongue construction. Always orient joinery to encourage water runoff away from critical intersections. Dovetail joints work exceptionally well for corner constructions where mechanical strength is paramount. For larger panels, consider ship-lap or rabbet joints with waterproof adhesives specifically formulated for outdoor use. Remember to angle all horizontal surfaces slightly (minimum 3-degree slope) to direct water away from joint intersections. Complement these joinery methods with stainless steel or brass hardware to prevent corrosion stains. Regular maintenance including seasonal cleaning of drainage channels will ensure your teak trash can remains functional and beautiful for decades, effectively preventing water damage through superior woodworking techniques.
