Steps On Sealing Crawlway Vents In Concrete Walkways

There are a few steps to seal crawlspace vents in concrete walkways that we will cover in detail in this section:

Step 01: Prep The Area

When sealing around a crawlway vent next to a concrete walkway, it is essential to clear out any garbage around the vent. This includes leaves, sand, rocks, and anything else clogging up the area. Sealing the vent keeps moisture and pests out of the crawlspace, but it is crucial to ensure the area is clean.

Otherwise, the sealant could fail to adhere and create gaps that allow moisture and pests to enter. Use a wire brush to scrub any loose concrete or mortar around the crawlway vent on the concrete walkway. By doing this, you will create a better seal and make it more difficult for water to seep through.

It is vital to seal the cracks or gaps in the concrete itself. This will help to prevent water from entering the crawlway and causing harm. These basic steps will help protect your home from water leaks and ensure that your crawlway remains in good condition.

Step 02: Patch Up

It is crucial to patch up any cracks or holes in the concrete before sealing around a concrete crawlway vent. Hydraulic cement or concrete sealant can be used to fill in these spaces, and it is vital to make sure that the surface is as smooth as possible before moving on.

This will help to ensure that the sealant will adhere correctly and that there are no gaps through which water or pests could enter. Failing to take these precautions could result in leaks or infestations, so it is vital to take the time to do the job right. These simple actions can help keep your home in good condition for a long time to come.

Step 03: Seal with Silicone Caulk

Once the cracks and holes are patched around a concrete walkway crawlway vent, it’s time to use a caulk gun to apply silicone caulk around the outside edge of the vent opening. This will help create a weather-tight seal to prevent water and pests from accessing the crawlspace.

Be sure to select a high-quality silicone caulk designed for outdoor use. Also, follow the manufacturer’s instructions for cure time and temperature before walking on the newly sealed surface. By taking these simple steps, you can help to keep your home dry and comfortable for many years.

Step 04: Smooth Out The Caulk

Smooth Out The Caulk

When caulking around a vent in the crawlway of a concrete walkway, it’s important to smooth out the caulk so it’s evenly distributed. You want a thick layer of caulk so that no water can get through. A good way to ensure an even distribution is to use your finger to smooth it out. This will also help to create a thicker layer, which is essential for keeping water out.

Be sure to seal any cracks or gaps around the vent. Even the tiniest opening can allow water to seep through, so paying close attention to detail is essential. By taking these measures, you can effectively safeguard your residence from flooding and water leaks.

Step 05: Let it Dry

Allow everything to dry for 24 hours before moving on to the next step. This will assure that the caulk has had time to set and will create a strong seal. With these precautions, you can be sure that your concrete walkway is protected from moisture and pests. 

You can then install foam insulation made of rigid foam or any foundation repair products. This will save you money in the long run by avoiding costly repairs. These simple steps can help prolong your home’s life and prevent foundation repair costs.

Step 06: Set a Barrier

Once everything is dry, use duct tape or another sturdy tape to create a barrier around the entire circumference of the vent opening. This will help keep any water from seeping through while you’re working on creating a more permanent sealant around the vent.

It’s important to use tape to create a strong seal so no moisture can enter. By taking these precautions, you can help to avoid any costly repairs down the road. Once the barrier is in place, you can move on to the following step.

Step 07: Enrichment Sealing

Applying a concrete sealer around a crawlway vent helps to create a moisture-resistant barrier, preventing deterioration of the crawl space repair over time. This final step is vital to extend the lifespan of the foundation repair and protect your investment. The sealer will also help to keep out grit, particles, and other junk, keeping the area around the vent clean and tidy.

Sealing the vent makes it easier to detect future leaks or defects since any crawl space waterproofing will be readily apparent. Overall, sealing a crawlway vent is a simple and effective way to prevent costly repairs in the future.

Why Not Encapsulate a Crawlway Vent in a Concrete Walkway?

Why Not Encapsulate a Crawlway Vent in a Concrete Walkway

These are four reasons that you should never encapsulate a crawlway ventilation arrangement in a concrete walkway: 

Encourage Fungus Growth

In an area with high humidity, crawl space encapsulation can worsen things. This is because the humid air will get trapped under the concrete, creating a conducive mold growth environment. The trapped humid air can cause wood rot and attract wood-destroying insects.

It Can Harm Your Foundation

The purpose of foundation vents in your crawlspace is to allow air to circulate and prevent moisture buildup. If you seal off the vents, that moisture has nowhere to go and can start to erode your foundation repair. In fact, this is one of the most frequent causes of foundation wall problems. 

It’s illegal In Some States

In some states, it’s actually against the law to encapsulate a crawlway vent with concrete. This is because doing so can impact the safety of your home so it’s best to check with your local laws before making any decisions about your crawlspace vents. 

It’s Harder to Sell Your Home Later On 

Many homebuyers are turned off by homes that have had their crawlway vents sealed off. That’s because they know about the potential foundation problems that can come with it (like those we’ve just listed). So if you’re ever considering selling your home, encapsulating your crawlway vents could make it harder and take longer to find a buyer. 

Should I Block The Crawlway Vent of a Concrete Walkway in Winter?

When cold weather hits, that outside air can cause your crawlspace to freeze. Ice can form on the concrete walkway’s underside, making it dangerous to walk on. An effective way to prevent this is temporarily blocking off the crawlway vent. Here are four reasons why you should do this during the winter months.

Keeps Your Crawl Space Warm

When you block off the crawlway vent, you’re trapping heat in your crawlspace. This will keep the area warm and prevent ice from forming on the underside of your concrete walkway. The result will make your walkway safer to use, and it will also prolong its lifespan. 

You Won’t Have to Worry About Pests 

One of the benefits of having a crawlspace vent is that it helps keep pests out. If you experience a lot of snowfall, chances are the pests are hibernating anyway. Blocking off the vent will help keep them out and give you one less thing to worry about during winter. 

Save You Money on Heating Bills 

You will also save money on your heating bills by blocking off your crawlway vent. By trapping the warmth in the crawlspace, you won’t have to run your heater as often or as high to keep your home warm. And we all know how expensive heating bills can be during winter.

Flooding Will Not Be A Problem 

Especially if you live in a region prone to flooding, blocking the crawl space vent can help prevent water infiltration in your home. Entering your home with water can degrade crawl space insulation, cause mold growth, and destroy HVAC ductwork and wiring. By keeping water out, you can protect your home from costly repairs. 

Precaution Tips for Sealing Around Concrete Crawlways

  • Make sure the vent is level with the surface of the concrete. If it is not level, the sealant will not adhere properly and could allow water to seep in.
  • Use a high-quality sealant designed for use with concrete. This will ensure that sealant will not break down over time and will provide a long-lasting barrier against crawl space moisture.
  • Apply the sealant in thin, even coats, and allow each coat to dry completely before applying the next. The process ensures the sealant forms a strong, durable barrier.
  • Wear the proper safety gear. It includes gloves, goggles, and a face mask to avoid inhaling concrete particles.
  • If possible, use a water-based sealant. This will make cleanup much easier if you get any sealant on your walkway.
  • Apply the sealant evenly and smoothly to avoid bumps or unevenness in your concrete walkway.
  • Lastly, follow the manufacturer’s instructions carefully to ensure the best results. Following these tips can help ensure that your crawlway vent is properly sealed and protected from moisture.
