Frequently Asked Questions

Do you sell to the public or only to contractors? +

We work directly with contractors, builders, and masonry professionals across the western United States. The public can purchase from us as well, although most homeowners hire a contractor who buys the materials on their behalf. If you need reinforcement solutions for your project or a jobsite, we serve you.

Do you offer delivery? +

Yes. We deliver directly to jobsites, making it easier to keep projects moving without delaying your crews.

What is the difference between contraction joints and expansion solutions? +

Contraction joints control cracking in concrete slabs and help reduce random cracking, while expansion solutions, such as backer rod, support sealing and movement across joint systems.

When should I use these products in concrete slabs? +

Consider using these products in concrete slabs during planning and installation to control movement, maintain proper joint spacing, and prevent cracking, thereby helping maintain structural integrity throughout the concrete structure.

How do these products relate to isolation joints on a project? +

They work alongside isolation joints by allowing sections to move independently, especially in areas where horizontal movement needs to be accommodated.

Where do concrete construction joints fit into the overall system? +

Concrete construction joints mark where one pour stops and another begins, and these products help seal and manage movement at those transition points so the overall concrete construction performs as intended.

Can these be used for decorative concrete joints without affecting appearance? +

Yes. They help maintain clean lines in decorative concrete joints, typically spaced to keep finishes consistent.

Are these products suitable for joints in concrete floors? +

Yes. They perform well on concrete floors by controlling cracking and sealing joints, often designed into layouts for consistent results.
