Exterior basement waterproofing is the process of installing drainage solutions and sealants to the outside of your home, which will prevent water from penetrating your foundation or leaking into your basement. Waterproofing basement walls from outside of the home is a more intensive procedure than interior basement waterproofing, which uses solutions from the inside of your home. Especially with how rainy it is here in the Pacific Northwest, it's crucial to work with a qualified professional who can examine your property and create a customized solution that will divert water away and help you prevent serious damage.
