20. ABSTRACT (Continue an reverse aide It necaaaary and Identify by block number) 



Pressure-treated timber has wide application in the waterfront and shore 

 protection structures that are built in marina developments and other shore 

 and beach locations bordering on bays, lakes, and river resorts. Because of 

 its strength, durability, and economy, pressure-treated timber is the principal 

 construction material for bulkheads, seawalls, piers, and groins at locations 

 with mild exposure and shallow-to- intermediate water depths.
