These services will include, but are not limited, to the following: Waterproofing basements from the inside and the outside. Exterior basement waterproofing will consist of excavation around the perimeter down to the foundation. Once the bottom of the footings is visible, the foundation should be cleaned and dried before applying any coatings or membranes. Liquid synthetic membranes like polyurethane and rubberized asphalt should be applied to the Exterior Basements. Pair waterproof coatings with a drainage system that guides high volumes of water away from the building. French drains are to be use for the basement drainage system. Install them in the perimeter trenches before backfilling. Surround the drain with gravel before adding any soil for backfilling. Once the waterproof coating is set and the drainage system is installed, backfill the trench with soil in 6-inch layers. At the 6-inch mark compact the layer before adding more soil. Continue until the trench is backfilled and densely packed. Use Grit sand as a common compacting agent. Interior waterproofing begins with digging a trench around the edges of the basement floor and a sump pit when installing a sump pump. Once the drainage system and pump are installed, seal the basement walls, and replace any wall material that was removed. Apply interior sealants to the interior walls and floors of the basement to prevent moisture from seeping through. Fill/repair any cracks/defects in the basement walls before applying sealant to prevent larger amounts of water from collecting in the wall and damaging it further. Create a continuous channel along the perimeter of the inside of the basement. Install a French drain and connect it to a sump pump system. Install a sump pump at the same time as the French drain. In the corner of the basement, excavate a pit that is a bit larger than the tank for the sump pump. Ensure it connects to the French drain channel on the perimeter. Install the sump pump and tank in the pit, connecting perforated pipe to the tank. Connect the sump pump to a discharge pipe positioned away from the building. Backfill interior French drains with gravel before relaying cement to fix the basement floor.
