“The outer part of your home’s wall is usually covered with a lot of dust and dirt that sticks to it. To make the process efficient, you need to clear the debris and dust thoroughly. The dirt and debris can be cleaned using a broom, brush, or scraper. Then wash it with a power washer.”

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.

Step 5: Choosing the right water-proofer

There are a lot of products that are waterproof. You have to pick the one that goes with the wall. The water-proofer should be selected based on whether the wall is concrete or silicate.

You can choose between a concrete coating, paint, or seal. Pick a plaster waterproof Additive to strengthen your walls.

Step 6: The water-proofer should be applied

Apply the water-proofer thoroughly on the walls with either a roller or brush. If you want to apply more than one layer, give a thin coat. Add the second coating after the first one is dry.

Step 7: Tar and heavy-duty membrane should be applied

“If you want to add more strength to the layer, you need to use a tar-based pitch after you’ve dried the cement. You can apply it on the 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: Gravel may be added

A proper base for the trench is below the footer. The drainage pipes are going to get adequate support from a 34-inches gravel base. Gravel is long-durable and provides enhanced protection.

You need to lay the gravel and the drainage pipe-cover. Next to the footer, level the gravel position and then back-fill it. Make sure the pipe is covered for at least 3-inches.

Step 9: Barriers made of fabric can be added

Attach the pipe with a fabric barrier. Ensuring a fabric barrier is going to keep dirt out of your system. Then build the top of the dirt relatively high and allow it to settle for a while. Slope the ground away from the walls for the run-off after.
