Basement Water Control VS Basement Waterproofing

A while back, we wrote a blog about basement water control vs. basement waterproofing. In older homes, it is especially important to understand the difference between these two options for addressing basement water issues.

Recently, the City of Lakewood issued a strong warning regarding the use of interior water control systems, including those used by many major competitors. Water control systems should not be used without first ensuring that your basement structure can safely support this type of installation. Structural concerns have become a significant issue in Lakewood.

Lakewood’s statement is included below, followed by our blog explaining the difference between a basement water control system and basement waterproofing.

To be clear, On-Call provides basement waterproofing systems. If you would like to learn more about the difference between these two options, please feel free to call us at 440-476-3602. We are happy to help.

Be it advised that some of our basement walls are in ill repair due to the age and material type that the foundations were built with. We have speed tile foundations, double wythe brick, sandstone, and rubble foundations in many locations. Many of these foundation types were originally set on undisturbed clay and do not have any footings, or full 4” thick basement floors that are required to install many of these systems. Water controlling specifications need to be submitted to the Building Department annually and with every project for review, as well as wall stabilization systems requiring steel beams to be placed vertically on the existing foundation wall, affixed to full footings, and tied to existing floor framing. Starting in 2023, the Building Department is requiring proof that footings and full 4” thick basement floors exist, along with engineered plans to install these systems. We will not issue any permits for stabilization systems for foundation walls that require the structural members be installed or permanently affixed to footings that (A) don’t exist or (B) are structurally inadequate. The burden will fall on the contractor and engineer/design professional (registered to practice in the state of Ohio) to prove to us that the system specified can be installed in every situation that is uncovered. Should you have any questions you may contact the Building Commissioner directly, (216)529-6295.

The State of Ohio now distinguishes between basement waterproofing and interior water control systems. Basement interior water control is a method for removing water after it has already entered the basement. Interior water control is not the same as basement waterproofing.

So how are they different? Water control systems use drain tiles connected to a sump pump to remove water from the basement and help keep it dry—hence the term “water control.” These systems manage water after it enters the basement, but they do not prevent water from getting in.

Basement waterproofing, as defined by Ohio’s code, refers to external waterproofing. It involves excavating around the exterior of the home to prevent water from entering the basement. This process includes exterior drainage solutions, sealant application, and several other steps designed to keep water out at the source.

Do you want water to enter your basement and then be removed after it has seeped in, or do you want an external barrier that prevents water intrusion in the first place?

We provide basement waterproofing systems. If you are experiencing basement moisture or water issues and are interested in true waterproofing, please call us at 440-476-3602. We are happy to explain the difference between these approaches.
