When building a new deck or replacing a deck, consider how water-resistant the material is and how well it holds up to extreme weather. Moisture is the leading cause of deck rot and damage, and it can wreak havoc. Composite decking has become an alternative to traditional wood with its outstanding durability, water resistance, and low maintenance. But there are still many people who want to ask, is composite decking water-resistant?

Simply put, composite material is not 100% water-resistant. The only material that is completely water-resistant is plastic. But composite decking has been innovatively designed and manufactured. So that it is also highly water-resistant. This makes it ideal for wet environments or marina decks. In this article, we will discuss is composite decking water-resistant. And the factors that affect its waterproofing properties.

Why is decking water-resistant important

Extreme weather rain, ice, snow, or direct sunlight can cause serious damage to a deck. Prolonged standing water can cause traditional materials to expand and contract, and even develop mold and rot. So choose a deck material that is more waterproof and durable. This is important for creating a sturdy outdoor space.

Different environments can cause different kinds of damage to wood decks. Problems such as cracking, warping, and rotting are common due to expansion and contraction. However, EVODEK composite decking is virtually impervious to expansion and contraction due to humidity and moisture. Making it the perfect choice for wet environments.

Is composite decking water-resistant?

Composite wood decking is made from a unique blend of wood fibers and recycled plastic. As a result, it has excellent water resistance, but it is not completely waterproof. The only deck that is guaranteed to be completely water-resistant is a plastic deck. The only deck that is completely waterproof is a plastic deck. However, plastic is less sturdy and more prone to damage in extreme temperatures.

Composite material absorbs less water than wood. It also has superior durability compared to plastic. So all in all, composite deck board is a strong and durable option. That is also effective in waterproofing. If a homeowner is planning to create an outdoor space in a humid environment, choosing composite decks is a good decision.

Factors affecting the water resistance of composite decks

Composition

Composite decking is made using a mixture of wood fibers and materials such as polyethylene or polypropylene. These materials are pressed into decking through a special process. While wood is prone to may be damaged by moisture. However, the plastic component in the decking can be a good way to enhance its waterproofing properties.

The plastic content in the composite material protects the decking and minimizes water absorption. Therefore, it will not easily rot and swell due to moisture.

Design

EVODEK’s industry-leading design and manufacturing process results in greater moisture resistance. This allows the deck to be used in snow, ice, and wet environments without serious damage. The surface of the composite wood deck has an excellent protective barrier that keeps out moisture and prevents rot and mold growth. The moisture-resistant design makes it suitable for use in wet or frequently rainy areas.

Additives

Composite decking often contains additives in its composition. This is to enhance the durability and water resistance of the decking. These additives include mold inhibitors and water repellents. These additives are effective in preventing the composite material from collecting water, rotting, or getting wet. Although composite decks have good waterproofing features, you still need to avoid water and mold buildup over time.

Maintenance and care

Another important factor that affects the waterproofing of composite decking boards is care and maintenance. No decking material is completely waterproof, except for the plastic component. Therefore regular maintenance and cleaning will help keep composite decks waterproof.

Summary

To summarize, composite decking is all about good waterproofing. It can withstand rain, snow, humidity, and extreme conditions without serious damage. Although composite deck board is not completely waterproof, it can be kept well waterproof with simple cleaning.

Although it has good waterproof performance. However proper installation and regular maintenance can make it even more waterproof. It can allow you to maintain the integrity of your deck and overall structural integrity for a long time to come.
