Wood lumber has long been the standard building material for docks, piers, and marinas, but modern plastic lumber offers the same aesthetic with many additional benefits.

The constant exposure to fresh or salt water and harsh sunlight causes natural wood to break down rapidly, making it vulnerable to damage from boats, gears, and insects. Real wood decking requires regular maintenance, repair, and replacement to keep it safe and structurally sound. This makes real wood less than ideal for use in marine settings such as docks, piers, and marinas. 

Plastic lumber, on the other hand, is the perfect building material for piers and docks because it’s completely waterproof, durable, long-lasting, and resistant to rot, insects, and damage from regular use.  It never warps, swells, or rots, and the color stays bright and vibrant through years of sun exposure.

The Haven Dock & Marine line of plastic lumber 2x4s and 4x4s is tough enough to handle even the harshest marine conditions.

What Is Plastic Lumber?

Plastic lumber is a synthetic wood lumber alternative made from 100% polypropylene, PVC, or high-density polyethylene (HDPE). The plastic lumber material may come from virgin (newly made) or recycled plastic. Recycled plastic lumber contains post-consumer plastic, such as milk jugs, water bottles, and shampoo bottles. 

Plastic lumber is a great building material for deck boards, picnic tables, pergolas, sheds, and more. It’s great for DIYers because it’s easy to work with and an excellent wood alternative for anyone looking for low-maintenance building material for their dock, pier, or marina.

Benefits of Plastic Lumber

Plastic lumber is better than wood lumber for marine use for several reasons. Haven Dock & Marine’s plastic lumber is a long-lasting wood lumber alternative that never swells, rots, warps, or splinters, so it’s practically maintenance-free. It’s durable, long-lasting, and safer than natural wood for use in piers, docks, marinas, and more.

Waterproof

Real wood is porous and absorbent, which is problematic when building a dock, pier, marina, or anything else that regularly comes in contact with water. Natural wood can get waterlogged, making it prone to warping, damage, rot, mold, and mildew. 

Plastic lumber is completely waterproof, so it won’t warp, swell, or rot. You’ll spend less time sealing, treating, and replacing boards because your plastic lumber always looks as good as the day you installed it.

Fade-Resistant

Natural wood fades in the sun over time, no matter how you seal, stain, or paint it. Plastic lumber, on the other hand, resists fading for years and never needs to be repainted.

Insect-Resistant

Termites, carpenter bees, and other insects make their homes and meals from natural wood structures, which causes them to break down over time. Alternatively, plastic lumber is completely unappealing to most insects and bacteria, so you don’t have to worry about pest damage.

Slip-Resistant

Docks, piers, and marinas are always wet and often get slippery. Natural wood is prone to algae which can make surfaces extremely slick. Our plastic lumber decking boards, on the other hand, feature a specially textured, slip-resistant surface that’s still safe for bare feet. 

Easy to Install

Plastic lumber comes in convenient, pre-measured lengths that are easy to work with using standard woodworking tools. The same nails, screws, and saws you already have in your garage work with plastic lumber, too. And since each board is manufactured for building, you don’t have to worry about warped, uneven, or splintered boards complicating construction.

2x4 Plastic Lumber

Haven Dock & Marine has plastic lumber 2x4s in four lengths—6 feet, 8 feet, 10 feet, and 12 feet —to fit most marine building applications. They’re perfect for slip-resistant deck boards, splinter-free handrails, outdoor furniture, and more.

4x4 Plastic Lumber

Plastic lumber 4x4s offer superior durability for framing docks, piers, and any projects that need added stability. 4x4 lumber is the ideal choice for heavy-weight-bearing furniture and structural supports. Haven Dock & Marine’s plastic 4x4s are custom manufactured to outlast wood 4x4s against water, sun, and damage.

Eco-Friendly Plastic Lumber Uses

Plastic lumber is an eco-friendly choice for outdoor applications. Treated wood lumber can leach toxic chemical additives into the ecosystem, especially when exposed to moisture. Plastic lumber is waterproof, non-toxic, and can be made from recycled materials to be even more eco-friendly.

Docks, Marinas & Piers

Haven Dock & Marine’s plastic lumber 2x4s and 4x4s are just what you need for your boardwalks, ladders, swimming platforms, pilings, and more. With unmatched durability, plastic lumber stays vibrant and beautiful for years and never needs repainting.

Pergolas

Pergolas, gazebos, and other outdoor structures are much more resilient when you construct them out of plastic lumber. A plastic lumber pergola can better withstand the elements and won’t start to rot after sitting through rain storms, and is completely resistant to termite attacks. The handrails and benches won’t splinter, so you and your guests can enjoy your outdoor oasis for years.

Fencing

A plastic lumber fence is a long-lasting alternative to a traditional wooden fence that can take your landscaping to the next level. Whether you prefer a natural-looking wood grain or bright, vibrant colors, you can get the look of a classic wood fence with a much longer lifespan. You’ll never need to paint, stain, or treat your beautiful plastic lumber fence.

Railings

Plastic lumber is the superior choice for railings. In addition to providing a lower risk of splinters, it’s resilient to the elements and resists dirt and oils from grubby hands. Plastic lumber is durable and built to handle leaning, climbing, and furniture dings. 

Outdoor Furniture

Plastic lumber is a top-shelf building material for outdoor furniture, which is often exposed to sun, rain, and even severe weather. You can make durable picnic tables, Adirondack chairs, and just about any other kind of outdoor furniture out of plastic lumber from Haven Dock & Marine. 

Plastic lumber furniture lasts several times longer than natural wood furniture, whether it sits on your patio, pool deck, or dock.
