Exterior vs. Interior Solutions

Your house was NOT designed or built to leak. It was designed with the idea that the water that is outside will remain outside. When a leak develops, it’s a sign that something is not right and that it needs to be properly repaired. Sometimes homes leak because of the wear and tear that our mixed-humid climate and soils put on the foundation walls. Other times improper management of surface water on the property can compromise your foundation and allow water to enter your home. 

Most basement waterproofing today is being performed by franchise system companies. These companies profess to offer different waterproofing solutions, but they will direct you toward their system, which is usually an interior water control system. This one-size-fits-all approach to basement waterproofing benefits the system company more often than benefiting the customer. I can think of no other industry that so predominantly utilizes a system approach as opposed to a problem solving approach.

Regardless of the circumstances that have allowed water to enter your home, our first suggestion is always to keep the water out the way it was originally designed. Why? Because of our extensive experience & expertise in both landscaping & construction, as well as the latest in building science research.

Interestingly, if you do some research you’ll find that building scientists recommend against bringing the water inside your foundation so that you can then, in turn, manage it and pump it back outside (as in an interior water management system). All of the unbiased research that we have found states that interior water management systems should be used only as a last resort.

Exterior waterproofing is a permanent solution that works on the outside of your home to make your foundation walls impervious to water. This approach is greatly effective and ensures that water does not reach inside your home or your foundation walls in the first place. Your home will be protected from water damage by using our cutting edge waterproofing techniques and high-quality materials installed by our experts. 

Every exterior waterproofing solution is different because water gets into different homes in different ways. The main exterior waterproofing solution that we provide can be described like a waterproof jacket for your foundation. Figure 1 above shows the operation of an exterior waterproofing solution. The blue arrows represent water and, as you can see from the diagram, water tries to intrude, but is stopped from coming inside. The foundation is truly waterproof.

Using the latest in building science research, the best patented materials, and our proprietary waterproofing compound, we add layers of protection which will inhibit any water from getting into the walls of your home. This is a permanent solution that will also maintain your home’s structural integrity.

Most “waterproofing” companies will suggest that you bring the water in so that they can manage it. This is a sales tactic designed to point you in the direction of the in-floor systems that they stock in their warehouses. The in-floor systems they sell were originally designed for basements in the Midwest or other regions where all 4 basement walls are below grade. In those regions you have no viable option except to bring the water in and pump it out. This system makes your “waterproofing” reliant on mechanical pumps, electricity and backup batteries.

Figure 2 above shows the operation of an interior water management system. The blue arrows represent water. As you can see from the diagram, water is brought inside the foundation walls, managed along a pathway to a pump that pumps it back outside. This is not waterproofing because it entails creating a pathway for water to come inside your home, where it doesn’t belong and can do further structural damage.

An interior system is installed by jackhammering the slab above your foundation footing and against your foundation walls … it’s exactly what you don’t want to do if you have other options. Fortunately for you, our homes are built differently here and we do have options! Building scientists recommend against bringing the water inside your foundation so that you can then, in turn, manage it and pump it back outside. Interior water management systems should be used only as a last resort.
