Whenever man changes the environment by building roads, bridges, or buildings, there is a need for Solar Testing Laboratories.

Since our founding in 1969, STL’s engineers and engineering technicians have helped contractors, builders, developers and architects meet the demanding standards the construction industry and governmental agencies have placed upon

  • Structures made of concrete or masonry
  • Roads of concrete or asphalt
  • Soils composition
  • Steel erection, welding, and associated construction operations
  • Property and building environmental and energy concerns

As an independent geotechnical, environmental and materials testing company, our engineers and technicians report on the quality, soundness, durability, and suitability of structural materials. The reports provide answers to such questions as: Will the concrete that is exposed to the elements withstand the effects of changing weather? Will a proposed bridge or airport runway bear the weight of heavy traffic? Will structural steel bolts or welded connections perform as they have been designed? Is the land on which an office building is proposed free from environmental hazards?
