I have just installed a 1.4m X 150mm X 50mm spruce beam between the garage and house. At present it is a good interference fit but I am a little worried when it gets saturated it might expand and put pressure on the brickwork. Is there any place I might find the information?


general wet to dry expansion is around 1% along the grain, 3%
tangentially roundn the trunk and 5% radially

But if constrained it should be OK.
