TimberTech DockSider

DockSider composite decking is built tough to resist damage from the sand, salt, sea, and sun — perfect for heavy-use spaces like marinas and boardwalks.

Firm Footing 

VertiGrain slip resistant surface adds a measure of safety when decks get wet. 

 

Superior Versatility 

Designed for all kinds of high-traffic, heavy-use spaces like boardwalks, amusement parks, stadiums, and universities. 

 

Lasting Looks 

Texturized to create the appearance of wood with a surface grain pattern that will weather naturally to a consistent color.

Less Work, More Play

At the Sea to Stay

What preservatives are in TimberTech decks' composite core to avoid rotting?

TimberTech composite decking is comprised mainly of high-density polyethylene and wood particles, but we also add proprietary ingredients to our formulation that offer increased protection from rot.

 

Will a TimberTech deck weather?

Any exterior product will fade over time to some degree – that’s the nature of nature. For the ultimate in steadfast color, our TimberTech AZEK boards are technologically engineered to show minimal fading, backed by a 50-year Fade & Stain Warranty. However, our uncapped wood composite boards will gradually weather, like wood, over time.
