For homes that experience seepage and flooding, an exterior waterproofing membrane might be an ideal solution for the problem. After having your home's foundation inspected by a licensed contractor, you may decide that this option works best for you. Here is what you need to know about exterior waterproofing membranes before you proceed with the project.
Solving the Problem from the Outside
Exterior waterproofing membranes seek to solve the problem of water seepage by preventing the water from making contact with your home in the first place. The membranes stop water from entering from the exterior, or as contractors refer to it, the positive side, of your home. Unlike filling in cracks in the foundation, adding a membrane takes a proactive rather than reactive approach. While the fix may be more involved than filling cracks or other measures, the membrane, once put in place, acts as a barrier that constantly protects your home.
The Installation Process
Installing an exterior waterproofing membrane involves excavating the ground immediately surrounding your home. The contractors will install a moisture barrier that wraps around the home before filling in the removed dirt. In some cases, the contractor may also install a French drain to channel water away from the home. There are several options for the membrane, including waterproof panels, spray-on coatings, and other types of moisture barriers. If your home has an attached garage or a new addition that is not part of the original foundation, the process may become a bit more complicated, but it is still possible to install this type of exterior waterproofing measure.
Exterior waterproofing can be more expensive than interior alternatives, but it also provides better protection than more temporary solutions. You can expect to pay anywhere from $15,000 to $30,000 for this type of waterproofing technique, though the cost will depend on the size and setup of your home. Shop around and get quotes from multiple contractors before you make a decision so you can get the best quality and the best price for your home's waterproofing needs.
Exterior waterproofing prevents the mold, mildew, and damage that can come from water seepage and leaks in your basement. Spending the money now to prevent your home from becoming damaged can help to prevent more serious expenses down the line, and it can also help to make your home more desirable to potential buyers should you ever decide to sell. Contact a contractor from a service like Rite-Way Waterproofing to see if an exterior membrane is the right waterproofing solution for your home.
