The U.S. construction materials testing equipment market is projected to reach approximately $3.6 billion in 2026, growing at a compound annual growth rate (CAGR) of 4.5% from 2025 levels. Some industry analysts project the market could reach as high as $4.41 billion in 2026, driven by high-growth segments in automated and smart testing solutions.

Within the broader market, cement and mortar testing represents a particularly fast-growing segment, with equipment demand expected to reach $1.85 billion in 2026. Growth across the CMT sector is being driven by increased focus on construction safety, more stringent regulatory compliance requirements, and rising demand for testing infrastructure to support sustainable building materials.

Industry trends are shifting toward automated, digital, and non-destructive testing (NDT) technologies. The U.S. construction sector is also projected to require an additional 499,000 workers in 2026, a labor dynamic that increases the importance of efficient, well-calibrated testing infrastructure on large-scale infrastructure projects.
