Drainage Diagram

Surface Drainage
Surface drainage solutions normally consist of 9″ by 9″ or 12″ by 12″ drains. A flexible PVC pipe is then added to channel the water away from the home. It should be noted that if there is not enough natural grade to drain the water away, you may need to invest in a pump and sump system.

Do I Need a French Drain?
A French drain is used to stop water from seeping into the foundation of your home. If water does seep under your home, it can move the foundation and this can cause a world of problems at a later date.

Foundation Drainage Terms

Collection Boxes
These 12" by 12" boxes are set into the ground. The top is just below ground level; this is where the water enters. The water is collected in the box and then moved away from the home.

Combo Drain
This is a French drain and a surface drain that are used together to remove excessive water.

The water that is disposed by the drain

French Drain
French drains are incredibly common. A trench that is covered with gravel which redirects the water away from the area and into a pipe at the bottom.  They can also be used to relieve hydrostatic pressure from retaining walls.

A grade refers to the inclination of the ground from a horizontal perspective. If you have a negative grade, the slope is towards the foundation. If you have a positive grade, then it is sloping away from the foundation.

Pop Up Valve
This is a drainage point where water can be allowed to flow from the pipe and away from the foundation. It consists of a spring loaded cap that opens and shuts according to the flow of the water.

Retaining Wall
This wall is designed to hold in soil. It is normally present in home constructions that require leveling on the construction site. Without a retaining wall, the foundation could be compromised by slumping or soil erosion.

Root Barrier
This process involves cutting the roots of trees that are present near a foundation and installing a barrier to stop them from growing underneath.

Sump Pump
This is a pump that is normally used to remove water that has accumulated under or around the foundation. Water is passed through the sump and moved away from the site by the pump.

Surface Drain
A surface drain consists of several collection boxes and a pipe. They are designed to collect and move water that collects on the surface of the foundation.
