Do you need an Interior Drainage System?

An Interior Drainage System is needed when a basement foundation is suffering from hydrostatic pressure against the exterior foundation walls due to a high water table.  The most common signs of a high water table are water seepage where the floor meets the foundation wall, leaks from floor cracks, and leaks or dampness across the bottom portion of a foundation wall or foundation cracks.

What Causes High Water Table Around Foundations?

A high water table is caused by poor drainage around the foundation footing as a result of one or more of the following reasons:

• Crushed/clogged or lack of French drain around the exterior perimeter of the foundation
• Improper drainage of surface water (towards the home instead of away from home)
• Excess water around foundation wall due poor roof drainage
• Freeze/thaw

It is difficult to identify the particular cause for the rising of the water table, since the problem originates on the exterior of the foundation wall or underneath the foundation floor, an area that is not visible.

Interior Drainage System vs Exterior French Drain System

Sous-Sol Solutions Installation Process

An Interior Drainage System is installed around the interior perimeter of your foundation wall as follows:

1. A portion of the floor, approximately 1’ wide, around the perimeter of the foundation is removed.
2. A trench of approximately 1’ wide and 1’-1.5’ deep is created.
3. A bed of 3/4″ washed stone is placed in the bottom of the trench.
4. 4″ PVC perforated pipes with cleanout locations are installed in the perimeter trench and pitched towards the Sump Pump System.
5. The Sump Pump System is installed at the lowest point of which the PVC perforated pipes where pitched.  The sump pump pit sits in a hole, flush with the floor level and surrounded with 3/4″ washed stone.  The PVC perforated pipes are connected to the sump pit. The sump pit also has a bolt down cover.
6. Install inspection caps (cleanouts) to the PVC pipes at the pre-selected locations.  Inspection caps are used in the future to access and, if needed, clean the inside of the pipes without having to dig up your floor.
7. Install Delta-MS membrane along the perimeter drain, starting from inside the trench and up the wall.  The Delta-MS is installed to collect the water from future foundation wall leaks such as wall cracks, tie rods, or window wells and drains the water behind the Delta-MS and into the Interior Drainage System.  No more water infiltrating onto your basement floor.
8. The trench is filled with more 3/4″ washed stone to cover around the PVC pipes to ensure a clear and clean path for water to travel into the PVC perforated pipes.
9. Concrete is poured over the trench and around the Sump Pump System, leveled with the existing floor.
10. The Sump Pump System discharges the water to the outside of the foundation and away from the home.
