Having problems with water pooling, flooding, or saturating your property? A-2-Z Outdoor offers a wide variety of underground drainage solutions to keep your property as healthy as possible. Capillary moisture is essential to good soil characteristics and plant life. However, gravitational moisture, and in many cases surface runoff, constitute excess water that is detrimental to the turf and other plant life. Gravitational water should be removed for turf and plant life to thrive. This can be accomplished with the proper surface drain.
