Exterior Drainage Systems

We specialize in many different types of drainage systems for a variety of needs, whether it be recurring standing water in your yard or preventing water from breaching your foundation and entering your basement or crawl space. Learn more about our drainage services below, then give us a call to schedule a consultation with our team to learn how we can help.

French Drains

French drains are designed to direct groundwater and water draining from your gutters away from your foundation and residence. They are also used to redirect groundwater in your yard into a designated collection container or a storm sewer, resolving standing water that is getting in the way of your landscaping.

French drains consist of first digging a trench that is slightly sloped to allow gravity to direct the water away from your residence. Once the trench is dug, gravel and landscaping fabric are placed on the bottom of the trench, making sure that the slope of the trench is still maintained. This helps to support the pipes that direct the water, as well as prevent tree roots from reaching the drain. Once this layer is in place, pipes that have holes drilled into them at regular intervals are inserted. The pipe is placed with the holes facing downward, allowing the groundwater to rise into the pipe and drain away. Another layer of gravel and landscaping fabric are placed on top to protect the drain from the elements and hide it from view. In some cases, concrete is used in place of gravel and landscaping fabric to provide a more secure encasement.

Curtain Drains

Curtain drains are quite similar to French drains, but are designed for the removal of water that pools on the surface of your yard rather than groundwater. Curtain drains require a trench to be dug as well, but these trenches are typically shallower than French drains and are covered with gravel. When surface water occurs, it seeps through the gaps in the gravel to enter the curtain drain and be directed away from your foundation.

Footing Drains

Footing drains are drainage systems that specialize in removing water from gathering around the foundation of a structure and seeping into your basement or crawl space. This method involves excavating the soil surrounding the foundation of the structure to allow room for the system to be installed directly alongside the foundation wall. Just like with French drains, this system consists of utilizing landscaping fabric to insulate the foundation from groundwater, followed by the installation of perforated piping and gravel on a slope. These drains circle the entire perimeter of the foundation water and direct water into nearby sewer systems or collection containers.
