Testing, Preservation and Protection of Wood and Wood-based Materials
We are engaged in the testing of wood protection products. We determine their effectiveness in protecting wood against wood decaying fungi, dye and mold. We determine the penetration and retention of wood preservatives, and the corrosive aggressiveness against steel of these agents.
