Highway Drainage Systems Our nation's highway's are old and in need of resurfacing, repair or replacement. Part of the problem is excess moisture trapped beneath the road surface in an area known as the sub-base. When water becomes trapped in this area, the weight of the vehicles, the loss of compaction and other factors cause serious damage that translates to the surface in the form of small cracks. These cracks grow into gaps that eventually break off or crumble to form a pothole. Need I say more?In some cases, totally rebuilding long stretches of interstate or state roads is the only solution. Before milling and re-paving, install edge drains on both sides of the roadway to remove trapped or unnecessary sub-base moisture. The edge drain's effectiveness has been measured countless times an existing roadways in a number of states. The results range from fair to excellent and are soil and site specific. Installing slope drains for new construction to help prevent erosion and provide a temporary outlet for rainfall is a cost-effective way to hold your position during periods of unanticipated rainfall. Culverts are pipes that normally convey water beneath and perpendicular to the roadway. We manufacture these large-diameter pipes for that purpose.
