Interior Basement Drainage System

An interior basement drainage system includes a sump pump system (including a primary sump pump and possibly a backup sump pump), sump pit for groundwater to collect, as well as a perimeter drainage system to direct water to the sump pump. For some homes and properties, a sump pump and sump pit alone may be sufficient at collecting water and redistributing enough water to lower the water pressure around the house. Other properties may require the interior basement drainage system to maintain a dry basement.
Interior Basement Drainage System
An interior basement drainage system is installed under the basement floor, along the entire perimeter of the basement foundation. The perimeter drainage system is a system of long trenches that are cut/drilled to and excavated using various industrial tools. There perimeter trenches are created where the wall and the floor meet. For most homes and systems, the job can be done in as little as 2-3 days, and most of it is done inside the home. Check with the contractor doing your estimate to inquire about guarantee plans of both the sump pump batteries and engines, as well as the drainage system.

By going with the more sophisticated interior basement drainage system, you eliminate continued water problems some homes endure, despite the instillation of a previous sump pump installation. In a perimeter drainage system, the water is collected and redirected from below the slab, the most common point of groundwater entry. This system allows water to drain away to the sump pump before it can rise to the seam between the wall and floor of the basement. By keeping the water level (water table) below the foundation walls, there the water simply won't be there to drain into the house through the wall cracks. Also, the perimeter system will make sure that the water table is at a low level along the entire length of the house, not just near the location of the sump pump.

Our interior basement drainage system is able to collect and redirect the water, while keeping soil particles and other debris back. The purity of the water passed towards the sump pit will prevent any damage or clogging of the sump pump. Our system consists of a 3-dimensional, high-flow, drainage core which is enclosed with a non-woven filter fabric. This fabric around the drainage core is permeable to water only, prolonging the life with the sump pump without sacrificing performance. To keep the system efficient and clean, the drainage core is enclosed in a layer of clean crushed drainage stone.

When the installation begins, the perimeter is removed along the entire length of the foundation. The foundation walls, footing, and overall structural integrity are maintained despite this excavation, because the foundation and footing itself are not damaged or removed. Once the trench has been drilled and cleared the drainage core is installed and clean crushed stone is filled around it. Once the core has been laid and the rest of the trench filled with crushed stone, a fresh fill of concrete is laid back on top of the layer of crushed stone. The fresh, wet layer of concrete is smoothed over, the area is cleaned, and your basement has a new waterproofing system while taking up very little space, and would be ultimately unnoticed by a visitor to your home.
