Long-Term Deck Waterproofing Options

by Priscilla Terry

As a residential property owner, waterproofing your outdoor decks may be something you are considering. In many cases, when decks are first installed, they are already waterproof or sealed. You may also consider using lumber that is pretreated and water proved. However, over time, the waterproofing does fade and needs to be reapplied. If you are concerned about frequent reapplication, then you may want to consider options for the long-term. Here are a few of those options and what to know about each.

Waterproof Vinyl Decking Boards

An increasingly popular option with many homeowners is to have waterproof vinyl decking placed over the original timber decking. This vinyl decking fits onto the original timbers and secures on using an adhesive or vinyl packing. The vinyl offers a waterproof solution similar to vinyl siding and vinyl fencing. This is a long-term option that also includes a waterproof membrane underneath the vinyl to protect the top of the timber surface for a longer period of time. The vinyl is resistant to cracking and to water damage from freezing and ice-related weather.

Waterproofing Additives

If you plan on using traditional waterproofing methods, such as paint on or spray-on waterproofing, you may want to consider an additive. These additives include polymer and rubber cement-based additives. These are very similar to the type of additives you would see used on a waterproofing membrane on your roof. In addition to sealing the deck, they also offer resistance to the damage caused by moving outdoor furniture along the deck and general usage of the deck. Keep in mind, the general use of the deck or moving furniture on the deck can cause breaks in the wood and in the seal. These additives would help reduce the breaks and cracks that can lead to water damage.

Membrane Additions

When you think of a waterproofing membrane, you may think of a membrane that is used in showers and in flooring. The same type of membrane can be used with your decking. This waterproofing membrane helps the water from creating a water issue below the deck instead of just above the deck. Keep in mind, that under some weather conditions you may experience some flooding or some severe humidity that can cause water to form on the bottom of the deck that may not be sealed as properly as the top of the deck. This forming water can cause water damage, wood rot, and damage that is severe enough that wood planks need to be replaced.

Each of these waterproofing methods are available from most service contractors. If you are looking for any of these methods or you are looking for other deck waterproofing services, please contact a local deck contractor. They can help you with the options available to you and with scheduling an appointment for the service you choose.
