Tankhouse Maintenance Inc. is proud to be a distributor of structural strengthening products from HJ3 Composite Technologies. HJ3 Composite Technologies offers the most comprehensive line of strengthening products in the world for fortifying and protecting structures against earthquakes, blasts, and environmental damage. HJ3 relies on its design team of structural engineers, chemical engineers, mechanical engineers, project managers and construction specialists. This versatile product can be used to repair or increase existing strengths in a variety of structural components such as tanks, columns, beams, walls, floors, roofs etc. The wide range of applications for this product line makes it a product suitable for almost any industry which has structures which need to be maintained.

HJ3�s systems have been subjected to the most extensive durability testing in the industry. HJ3�s systems were subjected for 20,000 hours in continuous exposure conditions ranging from pH 2.5 to pH 12.5. These tests were accelerated in temperatures reaching 165F with accelerated UV and increased humidity. Carbon fibers have superb durability and remain structurally unaffected even after a long period of exposure to the various environments tested.

HJ3 offers the highest standard of turnkey engineering services, to customers who require engineering, that support its clients throughout the life of a project.
