Naturally resistant woods that are commercially available include
The best water resistant wood types & species. Iroko, Oak, Western Red Cedar, Cherry, Maple and heat-treated woods are just a few examples of timber that boast excellent dimensional stability and high resistance to shrinking and warping in the face of moisture.
While redwood or teak certainly qualify, five more common lumber species that also stand up well to sunlight, moisture and wood-boring insects are Western red cedar, Spanish cedar, cypress, white oak and mahogany. Red cedar tends to be knotty, but it's affordable and widely available.
Which Wood Lasts the Longest? Teak wood easily lasts the longest when used for outdoor furniture or decking. When properly maintained, it can last for the entirety of your life and years after.

Well-known domestic examples include cedar, redwood, old-growth cypress, mulberry, yew, osage orange, and black locust. Tropical wood examples include ipe, lignumvitae, purpleheart, and old-growth teak.
Properties. Western Red Cedar is one of the world's most durable woods, as it has a natural resistance to moisture, decay and insect damage. It has twice the stability of most commonly available softwoods due to its low density and shrinkage factors.
Teak. Teak is the most highly recommended material for wooden outdoor furniture among designers, not only due to its resilience in any season but also because of its style and soft, grained finish. This miraculous material produces its own oils, making it unique in comparison to other types of natural woods.
While similar to standard exterior plywoods, marine plywood is the highest quality (AA, AB, and BB), constructed from wood without knots. Eliminating the knots in wood improves durability because it practically eliminates the possibility of water pockets forming within the wood.
The best woods for water resistance are hardwoods that have a straight grain and dense woods that prevent moisture from penetrating a structure. Among one of these options is cedar wood.
Common red oak has a Janka hardness of 1220 lbf, meaning it takes 1220 pounds of force to drive the steel ball halfway into the wood. For reference, soft balsa wood requires only 67 lbf and the hardest wood in the world, Australian Buloke, has a Janka hardness of 5060 lbf.
Liquid sealants are one of the most common ways to waterproof wood. These sealants are applied directly to the surface of the wood and form an impermeable barrier against water penetration. It is important to apply several coats of sealant to ensure a thorough application.
Polyurethane, varnish, and lacquer are tried-and-true sealants with excellent waterproofing properties. For best results, apply the wood finish at room temperature, ideally between 65 to 70 degrees Fahrenheit.
The truth is, waterproof hardwood flooring does exist—but it's rare. And most of the products that claim to be waterproof hardwood are actually waterproof wood hybrids, or waterproof laminate floors.
OSB was invented back in 1963 by Armin Elmendorf. This wood sheeting is made from 95% wood chips and 5% adhesive. Indeed, OSB is made by mixing resin with strands of young wood to achieve a hard board. This is then waterproofed to increase its durability.
What is the best sheet material for external use? The best sheet material for external use is plywood. There are four main types of plywood: marine, structural, exterior and interior. Marine plywood is designed mainly for exterior construction, such as boat-building and lake platforms.
Since it's widely available, fir can be useful for those running a slightly tighter budget. It's one of the cheapest woods for outdoor use. If you're a woodworker or DIY garden furniture maker, this species also works and machines well, in addition to holding finishes easily — whether a clear varnish, stain or paint.
Cedar wood may last over 20 years when used in outdoor structures, such as decks, pergolas, gazebos, or furniture. It can last between 15 and 20 years when used for constructing a fence or support posts.
Treated lumber is a pine that is often a more cost-effective option as it is treated with chemicals to resist rot, decay, and insect damage. It is also a more durable option than cedar, making it a good choice for areas that experience heavy rainfall or high humidity.
Among other water resistant wood types are White oak and teak. These are also long lasting woods resistant to warping, decay, cracking, or twisting. These dense woods do not need a lot of maintenance and have a natural ability to repel rotting, moisture & insects.
To deter the pests, homeowners can obtain heartwood-grade lumber for construction projects. Termites also tend to avoid specific species of trees such as redwoods, yellow cedar, Laotian teak, and cypress. However, these types of wood are not as long-lasting as treated lumber.
For example, Teak doesn't need any treatment which prolongs its lifespan because it is naturally durable and doesn't have much movement whereas kiln dried Oak does need treating to prevent it from: Losing moisture and shrinking in the summer.
