Yard drainage problems can be challenging to understand and know how to solve. It seems that water wants to do its own thing.
Let's discuss drainage systems for yards and simple solutions that remove water from wet yards. What are the best drainage systems for yards?
yards devalue your home's value and are a nuisance. The good news is that they
are fixable. I will explain some of the most straightforward systems for
improving yard stormwater drainage issues.
In Atlanta, the drainage experts estimate that 60 percent of homeowners have water problems in their yards. When purchasing a new home, homeowners rarely consider that the yard might be a problem. They look at the kitchen and the master bedroom but hardly ever explore possible drainage issues. It is only after a few rain events that they discover they have a drainage problem.
Advising homeowners about yard drainage problems has helped us to understand these problems and how to solve them. Let's take a look at some of the ways you can solve your drainage problems.
One of the most common problems I have investigated in the past 25 years is stormwater pooling against the house's foundation.
Why does yard drainage problems exist for so many homeowners?
starts with the grading of the yard during the construction of the house.
The first step is to excavate for the footings and the foundations. The excavation allows space for workers to construct the forms for the foundation wall. The contractor pours concrete for the foundations and backfills around the foundation with soil. Too often, the contractor backfills the foundation with loose soil. Rarely is the soil appropriately compacted. And over time, the ground against the foundation settles, and water flows against the foundation.
the landscape company plants shrubs around the perimeter of the house. The shrubs
and plants make correcting the sunken soil around the foundation difficult and
Building codes for Atlanta require a slope to direct water away from the foundation. The ground should slope a minimum of six inches in the first ten feet. This slope ensures that the water will not drain to the foundation but away from the foundation. Good grading contractors always provide adequate drainage by following the building code which prevents yard drainage problems.
Another standard construction method is to construct grass and rock swales to direct stormwater away from the house.
and rock swales are shallow ditches for conveying stormwater. Swales collect
stormwater and carry the water to an appropriate discharge point. Properly designed swales intercept stormwater and
direct the water to an exit point.
Drainage swales are shallow, U-shaped grass or rock ditches constructed to collect surface stormwater. They vary in width and depth depending on the amount of stormwater.
Designers use grass swales when the quantity of flow is small and the water's velocity is slow. Rock swales work best for greater flow and higher flow rates of water. They are constructed with sufficient capacity and slope to carry the stormwater away from the house.
The discharge point should not create drainage issues for the neighbor's property. Always be aware of where the water discharges. Take precaution to ensure that the discharge location will not affect the downstream neighbor.
Drainage systems for yards also include the stone swale. Stone swales are very popular with homeowners.
is an enemy of building foundations, and any measure you can do to prevent
water from reaching the foundation will help protect your home. Water that sits
against your foundation will eventually seep into your basement or crawl space.
Water damage experts recommend drainage systems for yards to drain water away
from house foundations.
Gutters and downspouts serve an essential function for carrying water from the roof to the ground. Never allow water from a downspout to directly splash onto unprotected ground surfaces. The water from the downspout will erode the yard and create pockets in which water will stand. Standing water will seep into the ground and saturate the soil around the foundation. Eventually, the water will seep through the concrete walls.
Standing water around your home is never a welcome sign. They often become a habitat for mosquitoes. Mosquitoes are more than a yard drainage problem issue.
