Exterior Waterproofing Vs. Interior Waterproofing

[vc_row][vc_column][vc_column_text]As a homeowner, you know how important it is to keep your home in the best condition. It’s not just because it’s a huge financial investment, but also because its the place where you escape to after a hard days work as a safe haven as your home.
If you live in an area thats prone to heavy snow melts, rainfall or storms, taking additional steps to protect your home against water damage is a necessity. And being the kind of person that really loves their home, you probably should consider waterproofing your basement. The problem comes when you have to choose among several methods of basement waterproofing.
More often than not, the choice comes down to external or interior basement waterproofing. Whats the difference between the two? Are they similar? Which one is more effective? These are some of the questions that go through the mind of homeowners.
Exterior basement waterproofing
External basement waterproofing involves building defenses to prevent seepage or leakage of water into the basement from the exterior of the house. Techniques employed include external waterproofing membrane, window wells, external drainage system, recreating the slope gradient of the grade and crack repairs among others.
Pros
� Other than landscaping or stuff you may want to move, there is little preparation thats required of you
� As most of the work is done on the exterior of the house, you do not have to give any of the internal space during the waterproofing process
� Professional exterior basement waterproofing is usually inclusive of drainage of saturated soil, thus helping to relieve the foundation from pressure
� Excavation during exterior waterproofing allows room for application of an exterior sealant, which is particularly useful for cinder block foundations
� They last twice or thrice the length of time that interior waterproofing systems do
Cons
� Exterior waterproofing is impossible to install in homes where there are attached garages, house additions or the neighboring homes are too close
� Installation of exterior waterproofing systems may force you to replace large fixtures like a concrete slab, the deck, pavement and even landscaping
� In the event that you have a full depth basement, this type of waterproofing can be labor intensive, thus expensive
� It doesn�t drain water lodged beneath the beneath unless a sump pit was installed prior to construction
Interior basement waterproofing
The main objective of interior waterproofing system is to ensure that any water that makes its way into the basement is rerouted and drained away from the house.
Pros
� Unlike with external waterproofing, it does not mess up with the landscaping or any fixtures in your yard
� Its not as labor intensive as exterior waterproofing and its therefore more economical
� The installation is not limited by weather, unlike exterior waterproofing which can be limited by extreme weather
� It relieves the floor as well as the foundation of hydrostatic pressure
� The system is not subject to external elements like soil, tree roots and debris among others
Cons
� Excavation is often required to expose 2 feet of the foundation from the bottom. This means removal of insulation, flooring, studs and drywall just to name a few.
â�¢ During the time of the waterproofing, the basement can’t be used
� Even after waterproofing, water can seep through, especially if the foundations are made of brick or stone
Whether you go for exterior or interior waterproofing, there are benefits as well as disadvantages that will accrue to you. The most important thing however is that you are making the effort to keep water out of your basement. And in any case, if you are not sure about which is more effective for your home, consultation with a qualified waterproofing expert in Toronto should clear the air.[/vc_column_text][/vc_column][/vc_row]
