Interior vs Exterior Basement Waterproofing
Interior and exterior basement waterproofing can be completed in several ways. Your location and your type of home both affect which interior and exterior basement waterproofing is best for you and your situation. There are many pros and cons associated with each waterproofing option. The information below will discuss several ways you can waterproof your basement and help you decide if whether interior or exterior basement waterproofing is right for you.
Cracks and Holes
Regardless of whether you are doing interior of exterior basement waterproofing, you have no choice but to repair cracks and holes. Patching them can prove challenging to say the least. For interior basement waterproofing, you have to brush away loose concrete to get a decent surface. You will need to use concrete to fill the holes and cracks, then smooth it out. The process is time consuming and complicated. Exterior basement waterproofing is done in such a way that cracks and holes are not much of a problem.
Skin shielding is used only with exterior basement waterproofing. Essentially, a skin is placed over the exterior basement wall after waterproofing paint has been applied. The skin acts as a moisture barrier between the cool soil and the excess water. The skin is rubberized and has a honeycomb design.
Interior and exterior basement waterproofing will always utilize waterproofing paint. The paint is applied just like any other kind of paint. It is typically latex based and does not allow water to adhere to it or degrade it over time. Exterior waterproofing paint is more durable than interior waterproofing paint due to the constant bombardment of moisture and rain that is must withstand.
Creating water drainage is an important part of waterproofing the basement. In order to keep the interior of the basement dry, you need to install a drainage system outside of your home. There are many ways that it can be done, even with the simple pipes like downspouts. Another way is to create a trench at the base of the exterior wall and place a drain pipe inside the trench, and have it connect to the exterior plumbing line. It will keep water away from the concrete foundation and out of the basement.
When it comes to exterior basement waterproofing, the water sock is a popular choice among builders. The water sock is a round piece of absorbent material wrapped in a mesh. The land around the home is excavated to the base of the foundation (also the basement walls). A trench is dug and filled with 1-inch of sand. The water sock is set in the sand and covered with gravel.
The trench is dug around the perimeter of the property and then the earth is backfilled over the water sock before it is leveled. When it rains, the water soaks through the ground and reaches the gravel. The water filters through the gravel to the water sock, where it is stored. Over time, the water is slowly released back into the ground.
