The Story Of SDI

Starting small and organically growing to exponential proportion, SDI grounded itself in sound business principals and a fundamental approach to construction, all while fostering a can-do attitude toward executing its goals and objectives. SDI’s core focus and competencies are anchored in foundation drilling, micro-pile, ground anchor and shoring construction, performing both public and private work in CA, OR, WA, NV and AZ. SDI further established itself as the premier solar foundation installer in the Western United States
