Storm Shelters
FEMA-certified underground storm shelters constructed with 5,000# psi concrete and reinforced steel. Designed to withstand 250 mph tornadoes, these shelters feature powder-coated steel doors with three-point latching systems. Tested at Texas Tech University's Wind Engineering Research Center, they provide secure protection for families during severe weather events.
Retaining Walls
Redi-Rock retaining wall systems using wet-cast concrete blocks with various architectural finishes. Available in gravity and reinforced designs, these walls solve erosion challenges while creating usable land. Systems can reach heights exceeding 30 feet without traditional tie-back requirements, combining structural integrity with aesthetic appeal.
Agricultural Products
Durable concrete cattle guards, feed bunks, and water tanks engineered for agricultural use. Products feature 5,000# psi concrete construction with steel reinforcement, meeting DOT weight requirements. Designed for longevity in harsh farm environments, these solutions reduce maintenance costs compared to traditional materials.
Wastewater Systems
Comprehensive wastewater treatment products including septic tanks, aerobic units, and subsurface drip systems. Certified NSF/ANSI Standard 40 Class I residential units and commercial systems handling 3,000-100,000 gallons daily. Partnerships with leading manufacturers ensure advanced treatment technologies for regulatory compliance.
