Foundation Drainage Solutions Save Foundation Repair

Why Would I Need A Foundation Drainage Solution?

Every home needs the right amount of foundation drainage. If you don’t have the right amount of drainage then you run the risk of needing a repair at a later date, something that you want to avoid at all costs. If your home does have poor drainage or if it collects within 4 feet of the foundation after heavy rain then you likely need a foundation drainage solution to relieve stress on the foundation of your  home.

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 boxes are normally 12″ x 12″ and they are set into the ground. The top is just below ground level and this is where the water enters. It is collected in the box, where it s 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
A trench that is covered with gravel – the gravel redirects the water away from the area and into a pipe at the bottom. French drains are incredibly common and they can be used to relieve hydrostatic pressure from retaining walls as well.

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.

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 and it 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 levelling 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. A barrier is then installed 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 then the pump is used to move the water away from the site.

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.


Swales also play a part in residential rainwater. They direct the water from downspouts to a street storm drain. They are very similar to agricultural ditches and they are very efficient when it comes to controlling the water flow. They also help to carry any pollutants from the roof, garden and lawn, so there are many benefits to getting one for your own home.
