Basement Waterproofing Frequently Asked Questions
How is the drain main installed?
The floor has to be a minimum of 3 1/2 inches thick over the footing. We start by installing the sump pump system first. This will help manage water flow during the process of breaking out the concrete along where the floor and walls meet. Beginning at the sump pump, we will remove concrete floor away from the wall approximately 6 inches wide and all the way down to the footer. We will set a short section of the Drain Main on the footer and verify that the vertical portion of the Drain Main will stick up above the floor surface a quarter inch to 1-inch after the cement work is finished. If needed we will use some fine rock to be poured over the footing to raise the Drain Main System to achieve the right height. We will continue laying out the Drain Main System using the pre-molded corners and sump drop kit until we have a continuous conduit along the open trench. Seems between the main sections will be covered with 3M vinyl duct tape to keep concrete from getting into the system while pouring concrete. Once the system is completely laid out and seems taped, we'll pour pea rock into the trench, filling up to the horizontal plane of the top of the Drain Main System. This will leave adequate space to pour several inches of concrete yet over the channel allowing for the back fin to stick up above the concrete and catch any water that may come down the wall through cracks or window wells.
