The presence of moisture or water within or beneath the pavement structure is almost always detrimental to some degree, depending upon many variables including pavement, base and soil characteristics, degree of saturation, the extent and range of moisture fluctuations over time as well as temperature variations.
Our GPS capabilities allow us to help identify pooling and ponding issues prior to a paving job being performed. This allows us to work together with our customers on a solution that meets their needs.
Underdrains are placed for base drainage, to remove excessive ground water, and to help control the excessive moisture under pavement surfaces. The most commonly used underdrain system is the pipe-aggregate underdrain system.
