The Complete Guide To Under Deck Drainage System

under deck drainage system

Under-deck drainage systems are innovative solutions that protect your deck and deck frame from moisture, which usually leads to wood rot and decay. These systems act just like gutter systems, effectively capturing and directing rainwater away from your deck and preventing it from seeping through the gaps in the deck boards, providing you with a dry space.

These systems are great for preventing any water damage, not only to your structure but to any electrical wiring that may be powering various devices on your deck (such as ceiling fans and TVs) that you might want to install in your outdoor living space.

That way, you can add utilities for lighting, ceiling fans, and entertainment centers to your deck without having to worry about water damage. You can also finish the space by adding under-deck ceiling systems or a soffit to cover up the deck joists and beams while also keeping them protected from water.

Benefits of Installing an Under-Deck Drainage System

Under-deck systems offer a lot of benefits for homeowners looking to protect their two-story deck. Some of these benefits include the following:

A Dry Space Beneath

Under-deck systems are designed to drain the water away from your deck, creating a dry area under the deck substructure that also doubles as an outdoor living area. Adding these systems is one of the best home improvement projects you can invest in, since you’ll be protecting your existing deck while also getting dry outdoor space beneath. 

Protects the Substructure

It’s worth noting that not all under-deck drainage systems are the same, but they do serve the same waterproofing purpose. These systems usually consist of a rubberized membrane that drapes between joists and creates a gutter-like system that directs the rainwater away from structural elements. Considering that you get a 25-year warranty on a new deck, adding these systems can significantly extend the durability and lifespan of your deck. 

Under-Deck Drainage System Options

Not all under-deck drainage systems are the same, and there are some notable differences in the way they function, though the results they offer are ultimately the same. For example, Trex RainEscape relies on gutter-like membranes and downspouts that divert the rainwater away from the deck, keeping the underdeck area dry. 

Those looking for a cost-effective solution might employ side paneling, which effectively channels rainwater away from the deck and often doubles as a finished ceiling secured via fasteners. There are also interlocking panel solutions that are typically made from aluminum and provide both an elegant and efficient solution for wicking away any potential moisture and rainwater.
