During the holidays, many homes had frozen or burst pipes that caused substantial damage. These repairs are costly and complicated. If left untreated, water leaks can cause mold, flooding and even structural damage. There are four common sources of water leaks: surface water running down foundation walls, groundwater in saturated areas, storm sewer water and sanitary sewer water. To protect your home from these kinds of water leaks, there are a few solutions. Here are the pros and cons of each: #### **Interior Waterproofing** [Interior waterproofing](https://www.disabatinoinc.com/services/interior-renovations/) is the most cost-effective and least disruptive way to waterproof your basement. It involves installing a French drain around the floor with a sump pump to draw water away from your home. In most situations, you will also need to seal all the water entry points from windows, doors and cracks. Applying sealants will plug the gaps and help lower humidity in the basement due to condensation. While interior basement waterproofing can be effective in most homes, it is not recommended for older houses or homes with severe water leaks. ![Basement interior waterproofing application showing French drain and sump pump system to divert water and prevent moisture intrusion by DiSabatino Inc. in Delaware County, PA.](https://disabatinoinc.com/hs-fs/hubfs/DS-Murphy-12.jpg?width=1200&height=800&name=DS-Murphy-12.jpg) #### **Exterior Waterproofing** Substantial water leaks may be a sign of a bigger underlying problem outside your home. In those cases, you need to have [professionals seal your home](https://www.disabatinoinc.com/services/grading-drainage/) from outside your basement walls. Exterior basement waterproofing requires a tunnel to be dug outside your foundation, where a barrier and sealants are applied to the outside of your walls. Rain gutters can also be rerouted to draw water away from the home. It is imperative to ensure downspouts are installed efficiently and situated correctly. ![Improved exterior drainage after waterproofing work illustrating corrected yard slope and drainage features to keep water away from the home foundation by DiSabatino Inc. in Delaware County, PA](https://disabatinoinc.com/hs-fs/hubfs/DRAINAGE-AFTER-EDITED.jpg?width=375&height=300&name=DRAINAGE-AFTER-EDITED.jpg) [Drainage](https://www.disabatinoinc.com/services/luxury-landscape-hardscaping/grading-drainage/) Problems Before ![Before photo of poor drainage causing water pooling near a home’s foundation indicating need for waterproofing and grading adjustments by DiSabatino Inc. in Delaware County, PA.](https://disabatinoinc.com/hs-fs/hubfs/DRAINAGE-BEFORE-EDITED.jpg?width=375&height=300&name=DRAINAGE-BEFORE-EDITED.jpg) Drainage Problems After #### **Drainage Systems** It’s essential to consult with a [professional landscaping firm before undergoing any drainage system work](https://www.disabatinoinc.com/services/grading-drainage/). There are a variety of systems to choose from, such as surface, subsurface and slope. These should be utilized according to the grade, soil and size of your lot. If done incorrectly, a drainage system will cause further damage to your landscaping and [hardscaping](https://www.disabatinoinc.com/services/luxury-landscape-hardscaping/handcrafted-hardscaping/) work. Different types of drainage systems include open drains, levees and grassed waterways. In certain conditions, you can install a swale that draws water away from your home. The swale is extremely effective, quickly moving water away from your home as soon as rainfall hits. Need help taking these steps to waterproof your home?
