Waterproofing a foundation before you install concrete is a smart choice and should be planned out ahead of time to ensure sufficient results. When scheduling a waterproofing contractor, make sure to plan for it on your layout plans ahead of time because during the hectic season it can get very busy. Determining where the finish grade line will be is important because you will not want the black material to be exposed. Layout lines can be marked with chalk to show where the finish grade will occur. If the foundation is somewhat simple, typically the waterproofing can be applied a few inches away from the top of the foundation. Keep in mind that there may also be things like intersecting walls, porch foundations, and others concrete that will also need to be waterproofed.
