Drainage Solutions

Drainage is one of those problems that you really should ask a professional to take care of. We've corrected many drainage disasters and have lots of satisfied customers with dry feet!

The following are various means to resolve drainage issues:

 

Regrade

This is usually the simplest solution if the problem consists of a few depressions or rises in the grade (high spots and low spots) over the area. The high spots can be cut down, the low spots filled, and the area resodded resolving the problem.
 
 
French Drain
 
This is a term for a system of perforated pipe that is covered by cloth, installed in the ground, surrounded by drainage rock, and covered by dirt/sod. Most often we are able to use the material from the ditch to fill and cover the drain, it is then tamped and the work is virtually invisible. Before the pipe is covered up we do a “flow check”. The less compacted area (rock) wicks out the water from the saturated soil. The water flows into the pipe and on to an outlet at a lower point. This outlet is either a pipe stubbed out through a wall, hill, curb, or ditch, or a pop-up emitter in the lawn area where drainage is normal and correct. Because many of these systems go in around foundations, or through utility areas, it is often necessary for the bottom of the ditch to be on solid or recompacted ground, these drains are hand dug and labor intensive.
 
 
Drain Boxes and Gutter Outlets
 
This is a system of small boxes installed in low-lying areas or areas where concentrated water flow occurs, i.e. the river flowing through your yard when it rains. The boxes are tied together with solid drain pipe along with any downspout connections from the gutter system. This system is similar to the storm drain system in a typical subdivision. It is most effective when there are several low spots over a large area, because it would cost more to regrade and sod than to install the drain system. It also works when you have raised beds, hardscape, or other drainage obstacles that are acting as a dam for the water.
 
 
 
Hybrid Systems
 
This is the kind of system we install most often. Typically drainage problems are a mixture of factors requiring a combination of the above systems to resolve the issues.
 
 
 
Positive Drain Flow System
 
This is when we need to install a pump to move the water, because any reasonable outlet point is at the same level as the drainage problem or higher. It consists of a 12” or larger drain box, with a float actuated pump, installed at a central low point with a back check valve and solid pvc pipe outlet to an area where water will drain away (ditch, curb, etc.). This system requires a power source and is often used in 
combination with other drainage solutions.
 
 
Note
 
Over the years, we have seen and corrected many improperly installed systems, perforated pipe not “socked” (covered with cloth), perforated pipe where solid should be or vice versa. If large volume flow areas (gutter, drain boxes) are connected with perforated pipe, the force of the water flow will push out of the pipe and create a drainage problem that didn’t previously exist, especially if the fall (downward drop) of the pipe is marginal. Sometimes these systems are simple and common sense to install, but more often they are more complex than is typically considered. People try to save a little money and end up with little or no true drainage solution. Let us give you a price to fix your problems right the first time.
