The Benefits of Waterproofing Your Deck

Concrete Pool Deck

Deck surfaces can last for many decades with proper maintenance such as waterproofing. Our waterproofing contractors understand how concrete and other materials hold up in Southern California’s climate, exposure to rain and other water sources, and varying levels of use. Over time, water erodes and breaks down concrete. Combined with daily wear and tear, this can lead to more frequent, costly repairs and the need to replace it much sooner.

With regular maintenance, you can avoid this. Knowing when to schedule deck waterproofing is important. Consider treatment if you haven’t done so in a while or if you notice the following signs:

  • Cracks in concrete
  • Uneven surfaces
  • Pooling water
  • Decreased strength
  • A worn look

Benefits of Waterproofing

Moisture can have a detrimental effect on concrete’s strength and integrity. By waterproofing decks and patios, it is possible to:

  • Improve Longevity: A concrete surface can last for several decades, but only if it is cared for properly. A lack of maintenance and an absence of waterproofing can cause concrete to degrade much sooner, so you’ll have to spend on extensive repairs or even replace the deck years earlier than expected.
  • Strengthens Concrete: Although it has an inherent resistance to water, concrete will wear out with long-term exposure to moisture. Concrete near a pool or spa is especially vulnerable. A waterproofing layer reduces the chances of water intruding into the surface and causing damage from below and within.
  • Lower Maintenance Costs: Water intrusion can lead to structural weakening, putting your entire deck in jeopardy. Several issues, from cracks in the surface, to foundation damage, and many water-related problems, can occur. Fortunately, these maintenance issues and associated costs can be reduced with waterproofing.
  • Prevent Mold and Mildew: Mold and mildew take hold quickly in the presence of moisture. Growth can occur internally, causing deck damage and possible health problems. Waterproofing eliminates the conditions that support mold/mildew growth, as well as the reproduction of bacteria and other harmful microorganisms.

  • Update the Look and Feel of Your Deck: Waterproofing protects concrete from the elements, reducing the risk of cracks, stains, and other signs of neglect and degradation. It can sustain a concrete deck as a beautiful highlight of your home. You can even give your deck a new color or texture by adding a waterproof coating.
  • Increase Property Value: A deck or patio that’s in poor shape will make it hard to find a home buyer. No one wants to spend on refurbishments after purchasing a home. Therefore, deck waterproofing can boost property value and contribute to a higher profit should you sell your home at some point in the future.

The Ultimate Deck Safety Checklist

Decks are great places to unwind, relax, read a book, enjoy meals outdoors, cook on the grill, and more. You need to make sure you and your family are safe and secure on your deck. With people spend more time at home and outdoors, now is a great time to complete our ultimate deck safety checklist.

1. Remove everything from the deck.

To do a proper inspection, you need to remove patio furniture, your grill, and other such things from the deck. You’ll need to do this anyway, at some point, for full deck maintenance and deck waterproofing.

2. Check for mold and mildew.

Just because you don’t see mold and mildew on the top of decking boards, this doesn’t mean it isn’t hiding. You need to look in between the boards and under the deck, on the backside of the boards. Some decks are closer to the ground than others, so this might be a challenge. Don’t forget to check the base of the handrails and railings too.

3. Inspect screws, fasteners, etc.

Verify that all deck screws are tight and any fasteners or other hardware are secure. If you find anything loose, tighten it back up. If they are looking rusty, replace them if possible. If not, sand the rust off before you reseal the deck, and then make sure to apply the paint or sealant over the deck hardware as well.

4. Check for rotting and cracking decking boards, railings, supports, etc.

Wood rot occurs when decks aren’t sealed annually. The wood will feel soft if it has been oversaturated with water. When it dries out, it becomes brittle and cracks. Replace any rotting or cracking parts of the deck. If the deck is more than 10 years old, then it is better to just replace the deck with a new one.

5. Inspect the deck supports.

If your deck is elevated off the ground, you need to check the deck supports for mold, mildew, rot, cracks, and so on. If the supports seem wobbly, then you will want to call a professional to have the supports replaced so the deck doesn’t come crashing down when you and your family are on it.

6. Inspect the stairs.

Verify the boards on the stairs are secure and safe. Grab handrails and gently move back and forth to confirm they are not loose. If they move more than a quarter of an inch, in either direction, something is wrong that needs to be repaired.

7. Check all electrical wiring, lighting, and the gas line.

Make sure all electrical outlets are working correctly. If you have exposed electrical wiring, verify the insulation is not cracked and that there is no exposed metal wiring. If you had a gas line connected to your grill, confirm there are no gas leaks by rubbing dish soap on the gas pipe and turning the gas on. If the soap starts to bubble, it means there is a leak.

8. Detail clean the deck.

Wash down the entire deck, including the decking boards, railings, handrails, steps, etc. You can use a power washer as long as you plan on resealing or repainting the wood once it is dry. At least once a month, make sure to sweep the deck off and rinse it down, using a garden hose to remove dust, dirt, and debris.

9. Waterproof the deck flooring.

After the deck has been fully inspected, repairs have been made, and it has been detailed cleaned, the last step before putting everything back onto the deck is to waterproof the deck flooring. Waterproofing protects the wood from rot. Certain waterproofing agents are also mold- and mildew-resistant. Some even offer anti-slip protection.
