Negative Side Waterproofing

Protecting your buildings from the inside out.

Negative side waterproofing means protecting your building from water from the inside.  A lot of times, this is the only choice for keeping your basement or underground areas dry because accessing the exterior or positive side of the wall is not feasible due to shrubbery or excavation issues.  For example, this can be done with epoxy waterproofing injections, and or cementitious crystalline products.

With the right negative side waterproofing, you can be sure that your structure will last a long life time.  Injection waterproofing fills existing cracks and crevasses.   Negative side waterproofing is an important ingredient in your waterproofing recipe.  Washington Waterproofing Inc., does waterproofing right by protecting all sides of the project.
