treated wood for underwater use

  • In 1995, the founder of Preservation Solutions, was approached by the head archaeologist for the Maine State Museum with a challenge to develop a better method of stabilizing and preserving waterlogged wood. Using our background in leather treatment and preservation, a formula for waterlogged wood conservation was conceived. Thus, SP-11 Waterlogged wood Treatment was developed. SP-11 has been tested on waterlogged wooden artifacts for close to 20& ...

Steel, concrete and aluminum are some alternatives to treated wood in cer- tain applications, but they have higher material costs, higher energy requirements in the pro- duction process, greater air and water pollution or environmental protection costs, and greater dependency on foreign sources for materials. Substitute materials may not be appropri- ate for some uses.

  • The manual is divided into three major areas: (1) deteriorating agents, (2) decay detection and evaluation, and (3) de- cay prevention and remedial treatment. Many portions of the information were derived in collaboration with the Department of the Navy. Causes of Deterioration. wood does not deteriorate as a result of aging alone. The service life of all commonly used construction timbers depends on their protection from a variety of deteriorating agents by means of construction and.
