Interior Waterproofing - The most effective of the interior drainage systems is a perforated drain pipe installed inside the perimeter of the footing. Not only are these the most popular systems, they are also building code approved when installed correctly. This requires removing and replacing concrete around the slab edge. By placing the drain pipe beneath the slab, it drains the area to a lower level. Similar to an exterior system, this drainage pipe connects to a sump pump system.
Exterior Waterproofing - Exterior waterproofing is true waterproofing. You need to stop the water from collecting around the foundation where it causes problems. Moisture is transferred from the outside of the building to the basement interior by four primary mechanisms. First, water flow. Water takes the path of least resistance, if this is into your basement, then that is where the water will flow. Second, capillary action. Concrete is a porous material, it is very hard yet porous. Think of capillary action being like a wick. As concrete sets in water, this water is absorbed by the concrete until it becomes complete saturated and then disperses moisture and water vapor to the inside of the home.
Step 1: Our installer removes a small section of the floor in the impacted area.
Step 2: The ECP product is inserted into the removed section of the floor.
Step 3: Small weepholes are cored beneath the floor slab to release hydrostatic pressure (block wall only).
Step 4: Remove section of the concrete floor is repoured to original thickness, ensuring its structural integrity.
