18 A log construction has a pair of logs, each having an end region with a surface portion thereon, wherein the surface portions are arranged to engage one another at a boundary therebetween, the boundary having a length. At least one barrier extends across the boundary and along the length thereof to couple the end regions together, the barrier having a pair of projections. Each of the logs has a passage open to and adjacent the boundary for receiving a corresponding one of the projections. Each projection has a pair of outer surfaces and the passage having a pair of inner surfaces, the outer and inner surfaces being further arranged to generate residual compressive forces toward the boundary as a result of shrinkage between the barrier and the end regions.
