The True Story About Basement Waterproofing

Unfortunately the sub-level, below grade basement waterproofing industry/business is a non-regulated, non-standardized procedural method. There are several theories and approaches to waterproofing an underground basement. However, this challenge is not one in which a more than one way to skin the cat approach can be taken. You can not take more than one approach or method to fixing a solid poured concrete foundation. This type of basement foundation is the most popular, that is solid poured concrete consisting of ready mix tumbled cement poured from a cement mixer/truck into a foundation wall-form on top of a previously cement poured footing set in ground below the basement walls. .

The only possible cause of water leakage/intrusion will be among four possible sources in a solid poured cement/concrete foundation. 1) A vertical wall crack running down the wall will typically run full height from bottom to top and throughout the entire thickness of the 10-12 inch wall. 2) A horizontal separation at the bottom of any perimeter wall where the wall and floor meet over the footing known as the key-way, existing most typically or commonly below each vertical wall crack in the form of an upside down T-shape, or even independently by itself. This water leak source along the bottom of a wall where the wall meets the floor, horizontally, is most always sadly mistaken for the need for a french drain trench-drainage system. In a solid cement poured concrete foundation the worst and most incorrect, (wrong), method or approach taken is a french drain trench because this method does not fix anything, it does not stop the water intrusion, it will cause or require breaking the internal side of the footing which will in-turn compromise the structural integrity of the entire foundation, and you will only be redirecting the water leakage some where else as well as increasing the volume of water intrusion. (3+4) The last two possible sources of water leaks would be a a hole from a gas or electric utility line or pipe or a basement window and/or its frame.

The other typical common waterproofing method or approach taken by most basement waterproofers other than the improper french drain is a surface application-patch-bandade-wall coating applied to either the exterior or interior side of a wall crack. Several materials form hydraulic cement to rubber to tar to surface epoxies as some sort of seven layer cake, regardless, it doesn't matter what is used this surface patch bandade approach is ridiculous, primitive, ineffective, wrong, and a total waste of time and money! Even if the patch successfully stopped the water leak it is not good enough because the one foot thick foundation wall is still broken, the foundation wall that the house or building rests upon is structurally compromised, and the water will ultimately leak adjacent to the same area or somewhere else. Rubber & tar belong on a roof, not on concrete. The problem here lies in that most basement waterproofers are former roofers with a common rubber and tar mentality. Most waterproofers are not engineers and they never consider the relationship of the wall to footing key-way, a most critical juncture.

One and Only One Solution : Structural engineered Liquid epoxy made for concrete and properly injected. Liquid structural epoxy is not a vanilla single product commonly sold in stores or trade supply distributor locations. Urethane and foam epoxies are cheap imitations and are not structural so don’t be fooled by some generic offering of any epoxy! We at B.Altmans Waterproofing are the only local residential waterproofer that injects the proper engineered structural liquid epoxy costing us 5X the cost of what all others use and still resold to our clients for the same price or less than what our competitors charge for inferior product/methods! This proprietary epoxy composition is unknown and unavailable to our uneducated, untrained, non regulated segment of the residential waterproofing industry. Our public record has demonstrated how we never fail. We always win & stop all water leakage intrusions while structurally repairing the foundation in which your house rests upon!!!

For homes or buildings that have foundation basements made of concrete block, or older homes made of stone or brick, (versus solid poured concrete), instead of a common French drain trench we engineer and install a much more advanced Vented Deck Drainage System over a Perimeter Pressure Relief System designed to depressurize and dry the perimeter foundation basement walls without compromising its structural integrity.
