On February 11, 2016, physicists announced the first confirmed identification of gravitational waves generated by a cataclysmic black hole event. The LIGO - Laser Gravitational Wave Observatory at Hanford, Washington has participated in the first discovery of gravitational waves from a distant collision in the far universe. LIGO Hanford, Washington, is composed of 2 fourteen foot diameter tunnels, each 4 kilometers long.  After being built the thin-wall concrete tunnels developed stress cracking over the outer surface and moisture intrusion into the tunnel interior. Crystal Lok was applied to the entire 4 k length of both sections, total 5 miles, by Matheson Painting Company, Pasco, Washington. See photos on our web pages at  and at LIGO Hanford We are very pleased with the success of that huge instrument and the science required for that success. Crystal Lok LLC (
