This edition of the NETCO Coastal Erosion Newsletter is about the use of green oak lumber for coastal applications.  Green oak is a coastal building material that offers several advantages over use of pressure treated or standard lumber.  We are also pleased to announce that the NETCO's coir envelope project at Blue,The Inn on the Beach (Plum Island, Newbury, MA) was selected to be the cover article for the International Erosion Control Association March, 2014 magazine.  More information coming soon.

Green Oak vs Pressure Treated Wood
During the last few years, NETCO has begun using green oak lumber rather than pressure treated 
wood for projects such as wetland walkway structures, sand drift fencing, toe anchor posts, dune crossovers, boardwalks, etc. Green oak is lumber that is milled but not kiln dried or chemically treated. Green oak is ideally suited for the rigors of the coastal environment and is a hard wood material as opposed to a soft wood such as pine, fir or spruce. It is an all natural product with no chemical treatment of any kind.


Through a unique pricing arrangement, NETCO has negotiated a pricing structure for green oak lumber which is only slightly more expensive than pressure treated wood.  NETCO is able to supply green oak for any project application in any dimension.  We can also sell green oak lumber direct to other contractors or to home owners, and we can ship anywhere in the U.S. and internationally.


Green oak is sold in the actual size of the lumber product; a 4 inch x 4 inch x 10 foot post is exactly that, 4 inch x 4 inch square x 10 foot in length.  Green oak is a Made in the USA product and is produced by a saw mill that is both FSC Certified as well as is an award winning forest manager in the northeaster US for thousand of acres of forestland for public organizations and private companies.

  Green Oak Posts

A recent NETCO project where green oak posts were used was for a sand drift fencing project for a private homeowner on Nantucket.  The green oak posts were 5" x 5" square x 10 feet in length.  The posts were spaced to hold 10' long fencing panels.  The sand drift fencing is designed to accumulate wind blown sand at the toe of the coastal bank thereby providing more protection for the coastal bank.  The sand drift fencing accretion period is usually during the spring to fall months with the winter period the erosion period.  A future newsletter will provide more information on several sand drift fencing applications.


REMINDER to our coir envelope customers:

If you currently have coir envelopes on your property now is the time to begin thinking about covering the envelopes with sand.  The high UV season begins late in May.  Exposure to UV rays degrades the strength of coir fiber; therefore, covering the coir with sand will extend the life and strength of the envelopes.  We recommend placing sand cover after the winter nor'easter season ends, usually late April. 


Please call us at NETCO if you would like help covering your coir envelopes with sand.  781-863-6270
