Sea Wall Update

The Redi-Rock sea wall is now complete!  Construction of the wall was delayed many times because of weather this winter but we were able to take advantage of a few good days and wrap it all up. When the ground thaws we will finish the details and cleanup that we're unable to tackle now.  Below are photos of the project from start to finish.  When the cleanup and sodding is done this spring we will post a few more pictures.  


Step 1: 12 inches of ice was broken up to be able to reach the pond edge!


Step 2: Line approximately 4 feet of the pond bottom and all of the pond edge with geotextile fabric.  This stabilizes the pond edge from erosion and also prepares it for the crushed stone base.  Metal stakes hold the fabric in place while the crushed stone is added.


Step 3: Adding the crushed stone base.  A laser transit was used to ensure the proper depth of crushed stone was added for a base as it was under water and not visible.


Step 4: Begin setting base blocks


Blocks are chained and lowered into place with an excavator while another crew member makes sure it's perfectly leveled before the next block goes in.

Doing the project in the winter was very important because the ground was frozen and the use of heavy equipment didn't cause any damage. In this photo, the excavator is sitting on the front of 4 North green above 12 inches of packed snow! 


Step 5: Once the blocks are in place, crushed stone is added behind the blocks and compacted for drainage and stability.


Construction of the wall is complete. Detail work (Step 6) remains to be done in the spring with the ground thaws.
