Drain Layer

An essential part of the civil construction industry in residential and commercial land development is installing appropriate drainage systems to protect buildings and infrastructure during intense rainfall and improve the process of stormwater run-off. Drain Layers work with plans to install, maintain or repair sewage and storm water drains to solve drainage /seepage problems. They repair wastewater treatment systems, below ground sanitary systems and on-site disposal systems on construction sites. Adequate drainage and correctly installed systems are integral to protecting public health and maintaining a pollution-free environment.
