Solar Ballast Block

In the project pictured above, Pyzique block is used to create beautiful accent walls containing small planter areas within a creative water feature.

The block's primary use is for structural retaining walls, however they are quite decorative and lend themselves to strategic design in custom projects.

Pyzique block can be suited to your project with dramatically different effects.

Bring in your project details, and our expert staff will help calculate the number of block needed and recommend a base material.

Please contact us with any questions regarding our structural block.

ASTM International Standards Certification

St. Vrain Block holds certifications of quality issued by the ASTM International Standards organization. C1262-10 identifies the standard test method for evaluating the freeze-thaw durability of dry-cast segmental retaining wall units and related concrete units.

Index Terms include:
absorption; compressive strength; dry-cast segmental retaining wall unit; freeze-thaw durability; freeze-thaw resistance; manufactured concrete units; Absorption; Compression testing--cement/concrete; Concrete masonry units; Durability--building materials/applications; Freezing and thawing--concrete/aggregate; Manufactured concrete/masonry units; Masonry units; Segmental retaining wall units;

The C1491-03 outlines the standard specifications for concrete roof pavers.

Index Terms include:
absorption; aggregates; ballast weight; cementitious; compressive strength; concrete roof pavers; durability; limestone; portland cement; Concrete construction materials/applications--specifications; Concrete roofing/waterproofing materials--specifications; Roofing materials/applications--specifications; Roof pavers; Structural concrete--specifications;

As solar power has become a modern solution to the quest for energy the need for Solar Ballast Block products has emerged. St. Vrain Block is excited to introduce our ASTM International Certified Solar Ballast Block product line.

Solar panels in zero-penetration, flat-roof applications require ballast weight to secure the panel to the roof. Applications include flat roofs when non-penetrating options are preferred. Solar ballast block provides the dispersion of point loads without the need for penetrating roofing materials.

This is a critical common factor in Colorado and surrounding states' where the tendency for high wind areas and above average snowfall abound.

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.

We are the preferred supplier for many solar panel installers and manufacturers throughout the entire Western United States. We supply the entire Rocky Mountain Front Range from Montana to New Mexico including the Nebraska and Kansas heartland as well as the entire Pacific coastal region.

Convenient access to the I-25 corridor and our 35-acre facility allows us the space to maintain large quantities of a diverse inventory. So, solar panel manufacturers or installers, alike can benefit from St. Vrain Block's wide range of sizes and weights of quality Solar Ballast Block.

We have been ASTM International Certified serving the Colorado and Rocky Mountain Front Range manufacturing quality concrete block products since 1934. 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.
