Solar Ballast Block
St. Vrain Block is excited to introduce our Solar Ballast Block products. Solar panels in zero-penetration, flat-roof applications require ballast weight to secure the panel to the roof.
We manufacture several sizes and weights of products that are specifically designed for the strict quality requirements of the solar panel industry.
High compressive strength and density combined with low absorption are important to the long-term durability of the concrete.
Lower-quality concrete can deteriorate in under a decade due to the aggressive freeze/thaw environment that the roofs and the ballasts create.
Our products surpass the requirements of ASTM C1491 for compressive strength, density and absorption. They also exceed the ASTM C1262 requirements for freeze/thaw durability.
We are the preferred supplier for many solar panel installers and manufacturers. Please contact us today to learn more about the products we are making for the solar panel industry.
