Concrete Supplies & Materials for Meridian, ID
Professional concrete contractors throughout Southern Idaho understand that a successful project depends on more than craftsmanship—it depends on materials that arrive on schedule, perform to spec, and hold up under real-world conditions. Conmas Construction Supply stocks the concrete supplies and materials that working crews count on for forming, finishing, repairing, and sealing projects across Meridian and the greater Boise metro.
We serve both professional contractors and hands-on DIYers, but our inventory is built around what professional crews reach for on the job—not a generic hardware store selection. Whether you're setting forms for a foundation, pouring a commercial slab, or applying cure and seal to fresh concrete, Conmas Construction Supply carries what you need backed by the technical knowledge your project demands.
Concrete Supplies & Materials We Stock
Our inventory is designed for professional concrete work from ground break through final seal. Here is what you’ll find in stock:
Concrete Forming Systems
Forming systems define the shape and structure of every pour, and the hardware holding them together must perform under pressure—literally. We carry forming hardware, form ties, snap ties, coil ties, and related accessories sized for both residential and commercial applications. Whether you're forming a residential foundation wall or a large commercial slab, having the right ties and hardware on hand keeps your crew moving and your forms secure. Our team can help you select the right system for your load requirements and stripping timeline, so you're not over-engineering a simple pour or under-specifying a demanding one.
Curing Compounds
Proper curing is critical to achieving design strength and surface durability, especially in Idaho’s variable climate. We stock membrane-forming curing compounds that meet ASTM C309 requirements, including white-pigmented and clear formulations for interior and exterior applications. Our staff can guide product selection based on your mix design and ambient conditions.
Admixtures
Admixtures give contractors precise control over workability, set time, and long-term durability. Our inventory includes air-entraining agents, water reducers, accelerators, retarders, and corrosion inhibitors—all ASTM-compliant and sourced from manufacturers whose products are trusted on commercial and civil projects across the region.
Rebar Supports & Concrete Accessories
Proper rebar cover isn't optional—it's often a code requirement. We carry a full range of rebar supports, bar chairs, and bolsters in plastic, wire, and concrete configurations to suit slab, wall, and elevated deck applications. All are stocked in the quantities contractors need and integrate easily into any forming setup.
Joint Fillers & Sealants
Control joints and expansion joints are only effective when properly filled and sealed. Our joint filler and sealant selection covers both new construction and repair scenarios, including backer rod, polyurethane sealants, and self-leveling formulations suitable for horizontal surfaces. We stock products rated for the freeze-thaw movement common in Idaho winters.
Concrete Acrylic Sealers
Acrylic sealers protect finished concrete from moisture intrusion, UV degradation, and deicing chemical damage. We carry solvent-based and water-based acrylic formulations suited for flatwork, decorative surfaces, and exposed aggregate finishes. Applied correctly, these sealers extend surface life and reduce long-term maintenance costs for your clients.
Concrete Epoxy Chemicals
Epoxy systems deliver high-strength bonding and chemical resistance for repair, injection, and coating applications. Our epoxy chemical line includes structural crack injection resins, epoxy bonding agents, and floor coating systems used by concrete repair specialists and industrial contractors throughout Southern Idaho. We can help match the right viscosity and cure time to your application.
