North River, Mathews, VA

Problem:
This property owners were having their bank being undercut at high tide such that trees were threatened and the first section of their dock was collapsing as the first set of pilings were undermined. They had tried pushing logs, bricks, cinderblocks, etc. into the undercut, but the salt water continued to scour out the soil and expose/kill roots the tree root systems.

Solution Set:
With the undercut several feet deep in places, ReadyReef built a coir log wall out in front of the embankment, slurried sand into the undercuts and filled up the entire space to cover up all raw, eroding surfaces. The coir logs were captured in a long lasting GeoWeb and planted with marsh grass. The root structure of the grasses will grow to become the primary soil holding mechanism. Notice the relative positions of the two trees at the crest of the embankment in the first photo versus the second one.


case study

Results to date:
After 5 months of growth, the marsh grasses successfully rooted in place, covering construction materials, and returning the embankment to a stable condition.


case study

One year after planting, grasses survived their winter dormant period and have entered Spring growth phase. Many of the plant tufts or sprigs will now send out runners to further fill in unrooted soil areas.
