Many complexes have drainage issues- water coming into units, erosion, and standing water which can cause safety hazards after freezing. Most water infiltration is due to leaders dumping into lawns as well as previous drainage systems that have failed. Often times these systems use undersized, inferior pipe that is not pitched properly and has collapsed. Our solution is a custom design for every problem, covering the entire process from engineering to finished landscaping. We engineer and install drainage systems using a large 10 inch to 12 inch ABS lined trunk line, with 4 inch schedule 40 PVC pipe running to all the laterals. We install surface drains as needed and tie the whole system into the existing storm water infrastructure or out to daylight.
