9 Simple Steps to Waterproofing Exterior Walls

“The foundation of your home is built up by Waterproofing Exterior Walls. You need to pay special attention to your house’s exterior walls because the weather out there will not be nice. It is not enough to paint your wall. After dealing with rain, snow, wind, dust, and the heat of the outside environment, the paint will begin to peel off.”

Thus, waterproofing is the best way to ensure that your walls are protected and retain your house’s longevity. At the same time, it is vital to reduce your frequent renovation cost. So, here are some of the simple steps for providing effective waterproofing solutions to your home.

Damp carpets and beneath wall coverings can be the most prominent place for mold and mildew growth. Finishing a basement without first dealing with the moisture problems can make health conditions worse and lead to significant damage. Interior waterproofing systems, installed by a professional contractor, can keep moisture away throughout the home.

Step 1: Properly expose the outside part of the wall

Make sure your exterior walls are exposed properly before waterproofing them. Your house walls possess a lot of dirt, which creates an additional layer over the wall. Get rid of all the filth and dust from the walls. And before doing so, remove all the drainage pipes and the old field tiles to get proper access to every corner and area of the wall.

Step 2: Thoroughly clean the walls

“The outer part of your home’s wall is usually covered with a lot of dust and dirt from the outside. To ensure the efficiency of the process, you need to clear off the debris and dust thoroughly. The dirt and debris can be cleaned using a broom, brush, or sandpaper. Then wash it through a power washer.”

Step 3: Check out for the cracks and fill them up

“Cracks and holes can develop on the exterior walls over time. Follow up the cleaning process with a thorough look at the cracks and holes on your wall to make sure it’s waterproof. Then fill them up with cement.”

Most homeowners get worried about cracks in the foundation. But the fact is, not all foundation cracks affect the home’s structural integrity. Sometimes cracks can be caused by shrinkage during the concrete curing process. These unsightly, non-structural shrinkages, commonly known as hairline cracks, don’t put your home in immediate danger. But on the other hand, structural cracks are serious business.

All over the internet and TV, you find websites and programs with step-by-step guides for DIY foundation repair. But the truth is that a foundation should not be experimented on in a DIY project. Foundation repair requires years of experience and specialized tools. When it comes to foundation repair, contact a foundation repair expert.

The mixture of cement penetrated inside the cracks and seals them. You should remove all the loose cement from the wall before applying the cement.

Step 4: Add a layer of cement waterproofing sealer

If you want to make sure your wall is waterproof, you need to apply a cement waterproofer. After applying the cement in the crevices, let it dry and then apply the waterproof paint sealer. Allow it to dry.

Step 5: Pick the right water-proofer

There are a lot of waterproof products in the market. You need to pick the right one for your wall. The water-proofer should be chosen based on whether it is a concrete wall or a silicate-based one.

You can choose between a silicate-based concrete seal or a concrete waterproof coating. You can add strength to your walls with a plaster waterproofing Additive.

Step 6: Apply the water-proofer

Apply the water-proofer with a roller or brush on the walls. If you want to apply more than one layer, give a thin coat. Allow the first coating to dry and then add the second one.

Step 7: Apply tar and heavy-duty membrane

If you want to add more strength to the layers, you need to use a tar-based pitch after drying of the cement. It should be applied to your exterior wall.

After that, you need to apply a heavy-duty plastic or rubber Membrane, which will ensure the proper care of your walls.

Step 8: Consider adding gravel

To lay the drainage pipes, you need a base below the footer. The drainage pipes will get adequate support from the gravel base. Gravel provides enhanced protection.

The gravel and the drainage pipe cover need to be laid. If you want to back-fill the gravel, level it near the footer. The pipe should be covered for at least 3 inches.

Step 9: Add a fabric barrier

Wrap the pipe with a fabric barrier. Ensuring a fabric barrier is going to prevent the formation of dirt. Then back-fill the trench and build the top of the dirt relatively high and let it settle for a while. Slope the ground away from the walls for the run-off after.
