When considering waterproofing the basement of your home, you may be wondering if this should be on primarily on the inside or outside. There are several ways to waterproof the basement of a home with the two main areas being interior and exterior waterproofing. It is best to learn about each method so you can make the right decision when waterproofing your basement space. Below is a rundown of each type and what to expect with waterproofing methods.

Interior Waterproofing

When it comes to the interior method, it is not actually waterproofing that is taking place. Water management is more so the issue being addressed. This is done when water is already in the foundation of the home. With this method, water that has entered the home will be diverted away from the basement by using a specific system such as a weeping tile system.

This method is used by homeowners who are worried about the outside appearance of their home. Landscaping is not disrupted during the installation process. It is best to use this type of system with structurally sound walls or concrete. This option is used to manage leaks temporarily and is ideal when excavating the property is not possible. This could be due to utilities on the exterior of the home as well as accessibility issues.

Exterior Waterproofing

The best option for waterproofing the home is with exterior waterproofing. This method involves the foundation wall and excavating must take place. The wall is cleaned and inspected for any cracking after excavating. The walls are then sealed with a membrane of waterproofing and drainage is put in place. This is known as weeping tiles and these are set at the side of the footing. With exterior waterproofing, the life of the wall as well as the building will have a longer life span.

The waterproofing helps the water to not enter the home and the property is protected from such issues as foundation erosion or frost. The method creates gaps and cracks that will need to be repaired instead of bothering with managing the flow of water. Any waterproof coatings that are used will be flexible and be able to move with the wall which will help to prevent any leaks in the future.

It is recommended that homeowners use exterior waterproofing whenever possible as it will help to fight erosion and help the property to remain structurally sound. Walls that are constructed of stone, bricks, cinder-block or aging concrete will benefit most from this method.

Overall, it is best to consult an expert. Have your home evaluated by someone who has experience with such waterproofing methods and can assist you with interior or exterior methods. You will be able to rest easy knowing that your home is protected from the elements and no damage will occur due to heavy rains or a natural disaster. By being proactive, you are saving yourself thousands of dollars in damage as well as time and worry due to damage to the structure or items in the home.
