Good Morning!

Here is my problem.  I manage a log structure, a two room log cabin built in 1858, which is used as a museum and it sits outside at my institution's main building.  It was moved there from a previous location in 1972.   It sits on a bed of sand and has a cement floor and a cement skirt to keep water out.  It was rechinked in 1994 and sprayed with linseed oil on the exterior.  Even with this preservation work and two dehumidifiers running 24 hours there is still damp seeping through the walls and exhibit panels curl. 

My question is to anyone with similar structures that are outside.  What do you do to maintain the log building?  

A second question is; how many museums have log structures inside another structure for preservation?

You may reply on or offlist.
