Drainage Systems


Drainage is often at the root of soil movement problems. NED CLYDE CONSTRUCTION, INC. installs practical and effective drainage systems engineered with high quality materials which are intended to last. We often install drainage systems around structures to help reduce the potential for foundation movement.

Heavy winter rains caused excessive surface water flows on a hillside behind several homes in Hercules. This condition was corrected with the installation of a reinforced concrete "V Ditch" and a short gravity retaining wall.

Sub-surface Drainage Systems


Water moisture migrating through the soil underneath homes has been known to cause foundation settlement. A well-constructed subsurface drainage system can collect and remove water moisture before it has a chance to seep underneath a home and impact the foundation.


This Danville home had standing water in the crawl space which over the years led to soil consolidation and foundation settlement. The deep sub-drain now collects the sub-surface water before it enters the crawl space. The foundation was underpinned with pipe piles and the floors were re-leveled.
