As foundation repair experts in South Carolina, we know that the type of drainage system in your home can make quite a difference when it comes to waterproofing and working with your property. Importantly, improper drainage can cause problems with your foundation and your crawlspace. This article explains the 4 types of residential drainage systems (surface, subsurface, slope, and gutters) to help you determine which type is right for your property.

  • Surface
  • Subsurface
  • Slope
  • Downspout and gutter

Surface Drainage System

For surface drainage to work properly, ditches need to be dug. The ditches are relatively shallow and act as funnels for run-off water. They guide the water away from your home to avoid water pooling or flooding. Surface drains are a necessity if the area is flat. In flat areas with a lot of rain, water pooling can cause a lot of problems without the proper drainage system. Surface drainage systems can also be used for buildings, walkways, or driveways to guide water away from important structures.

Subsurface Drainage System

Subsurface drainage systems, also known as the French Drains, are generally buried beneath the top layer of soil. This removes any extra water from soil that might have become waterlogged at the root level. If the roots of a tree or other plant become water logged they will begin to rot, causing the plant or tree to die. A subsurface drainage system requires deep underground ditches, pipes and a large drain to aggregate the water from the pipes. A sump pump can also be used to push water through the pipes.

Slope Drainage System

Slope drainage systems use pipes installed on an incline to naturally move water away from a structure, letting gravity do most of the work. The pipe can be made of concrete, plastic, or steel, and is wrapped with a durable grate to protect people and animals from falling into it.

Downspout and Gutter Systems

The downspout is connected to the gutter system of the home and guides water away from the roof to the ground. A downspout and gutter system is a crucial part of your home that collects the water captured by your roof. Without it, rain runs off of your roof, splashes against your house and erodes the ground. Over time, this can result in premature damage to your siding, erosion of your landscaping, and flooding of your basement or crawl space and damage to the foundation of your home. It is advisable to use a filter or cap to cover the top of the gutter so that the debris is washed away from the gutter rather than into it. There are many different materials that are suitable for gutters, as well as many different styles available from which to choose.
