Trusted Radon Gas Mitigation Solutions
Dranjer Corporation was founded in 1986 by Harold Westdal and Allan Grant, driven by a commitment to address the health risks of radon gas in homes. Our patented radon mitigation products, including floor drains and sump seals, were developed through rigorous research and field testing to provide cost-effective solutions for homeowners. With over three decades of experience, we have prioritized simplicity and durability in our designs, ensuring our valves seal out radon, insects, and odors while allowing water to drain freely. Our products are engineered to complement Active Sub Slab Depressurization (ASD) systems but often serve as standalone solutions, reducing radon levels by an average of 46% in independent studies.We emphasize transparency, affordability, and ease of installation, offering DIY-friendly options that meet stringent safety standards. Our team remains dedicated to continuous product improvement, guided by feedback from loyal dealers and customers. As a small business, we prioritize public health over profit, ensuring our solutions remain accessible to families seeking protection from radon exposure. Our long-term partnerships with dealers and adherence to quality control reflect our commitment to trustworthiness and client satisfaction.

Radon Floor Drains
Dranjer Corporation's radon floor drains use patented valve technology to block radon gas entry while maintaining drainage functionality. These passive systems require no electricity or maintenance, offering homeowners a permanent solution. Laboratory and field testing confirms their effectiveness in reducing radon levels by sealing the single largest entry point in concrete floors.
Sump Seals
Sump seals create an airtight barrier against radon infiltration through sump pits while allowing water to flow freely. The JS15 model integrates into sump covers, activating only under specific pressure conditions to maintain system efficiency. This solution works independently or alongside ASD systems without compromising performance.
Retrofit Drains
Retrofit drains provide immediate radon protection for existing floor drains through friction-fit installation. The DR2 model fits 2-inch drains, featuring a self-sealing mechanism that activates between water flows. These upgrades require no structural modifications, making them ideal for older homes seeking quick mitigation.
ASD-Compatible Valves
ASD-compatible valves enhance radon mitigation systems by preventing backflow while maintaining depressurization effectiveness. The F Series maintains seal integrity under negative pressure conditions, ensuring optimal performance in homes with active sub-slab depressurization. These valves balance airflow management with drainage requirements.
Catch Basin Covers
Catch basin covers protect large drains from radon infiltration while maintaining high water flow capacity. The CBR9 model fits drains 5.75-9 inches in diameter, combining radon protection with debris prevention. This solution addresses radon entry points in commercial and residential catch basins without compromising drainage efficiency.
