Concrete Sealing
RadonSeals deep-penetrating sealers protect concrete from water vapor, radon, and efflorescence. Ideal for basements, driveways, and pool decks, these water-based solutions strengthen surfaces while allowing them to breathe. Lasting up to 10 years, they prevent cracking, dusting, and freeze-thaw damage without altering appearance.
Radon Mitigation
RadonSeals products reduce radon infiltration by sealing concrete pores. This lowers indoor radon levels, addressing a leading cause of lung cancer. Solutions include sealers and test kits for homeowners and contractors, focusing on long-term safety and compliance with EPA guidelines.
Crack Repair
DIY and professional crack repair kits address foundation and floor cracks using urethane or epoxy. These systems stop water leaks and structural damage, with options for small DIY projects or large-scale commercial repairs, ensuring durability and ease of use.
Efflorescence Control
RadonSeals cleaners and sealers prevent efflorescence by blocking moisture that carries salts to concrete surfaces. This protects aesthetics and integrity, extending the life of sealers, paints, and flooring while reducing maintenance needs.
Mold Remediation
BioZap mold and mildew cleaners eliminate organic growth using natural enzymes. These products improve indoor air quality by removing musty odors and contaminants, suitable for basements, laundry areas, and damp environments without harsh chemicals.
