Services
Redi-Rock Retaining Walls
Our Redi-Rock retaining wall systems use massive precast blocks engineered for structural integrity and aesthetic appeal. These gravity-based systems eliminate need for geogrid reinforcement while achieving heights up to 40 feet. Available in multiple architectural finishes, they resist environmental stressors while providing long-term land stabilization for commercial developments and infrastructure projects.
Storm Shelters
FEMA-certified underground storm shelters constructed with 5,000 psi concrete and reinforced steel components. Tested to withstand 250 mph tornado forces, these units feature patented locking systems and corrosion-resistant coatings. Each shelter includes powder-coated steel stairs and electrical ports for emergency lighting systems.
Wastewater Systems
Comprehensive wastewater management systems including septic tanks, aerobic treatment units, and subsurface drip distribution. Our NSF-certified residential systems integrate with advanced control panels and effluent filters. Commercial solutions handle flows from 3,000 to 100,000 gallons daily using modular treatment configurations.
Farm Concrete Products
Durable concrete feeding systems and water management solutions for livestock operations. Products include cattle guards with DOT-compliant load ratings, frost-proof water tanks, and reinforced feed bunks. All units feature one-piece construction with 5,000 psi concrete and steel reinforcement for agricultural durability.
Custom Precast Solutions
Engineered custom precast components for unique infrastructure requirements. Capabilities include architectural elements, utility pads, and specialized transportation infrastructure. Our design team collaborates on projects requiring non-standard dimensions or material specifications, supported by nationwide manufacturing capacity.
