Good drainage is really important to ensure that your house stays dry and free of mold. If groundwater collects in the yard, it is not only an inconvenient eyesore for the homeowner, it will also lead to wood rot and mold.
The most reliable way to eliminate undesired, free standing water is to install different types of drainage, French drains with slotted pipes and gravel, catch basins with solid pipes to move water away to ditches/ponds.
Where land is flat, soils are dense or the water table is to high, a well designed drainage system is a priority. Without proper drainage solutions in place, water may collect undermining structures, drown expensive plants,and turning parts of your new landscape into perpetually wet area. This can be the most important issue for longevity of your yard and landscape. Due to development around some older homes, it creates issues of poor drainage coming from the new development.
Do You Have Drainage Problems?
A good contractor will analyze the nature of your yard, and may "shoot the grades" to establish the exact topography no matter how flat the site may seem. Spot elevations tell the contractor where problems lie so that they can solve the issue.
Ground water can also play an important role in drainage, and it is directly related to rainfall patterns. In the South there are low lying areas, the water table can be just inches below the surface. such conditions create all sorts of problems.
Rainfall is the periodic catalyst that sets drainage problems in gear. Where heavy downpours are common, poorly drained sites can become flooded for a short time if drainage structures and small catch basins are in place, or extended periods if they are not. Add heavy rainfall to a high water table and the potential for damage increases exponentially.
