Radon-control design for large buildings
We produce engineered radon-control design packages for new and existing large buildings, built to the ANSI/AARST standards and reviewed by a certified radon professional. Pick your building type or read the standard that governs your project.
By building type
Multifamily
New apartment and condominium construction designed to CC-1000-2018, the consensus standard for radon-resistant new construction in large buildings.
View design scopeApartments
Purpose-built rental apartment projects, designed to the CC-1000-2018 new-construction standard for radon-resistant large buildings.
View design scopeCommercial
Offices, retail, mixed-occupancy, and other commercial new construction with ground-contact slabs, designed to CC-1000-2018.
View design scopeSchools
New K-12 and education facilities, where children spend long hours on ground-contact slabs, designed to CC-1000-2018.
View design scopeMixed-use
Buildings that stack residential over ground-floor retail or office, where a single radon strategy has to serve multiple occupancy types.
View design scopeBy standard
CC-1000-2018
The consensus standard for radon-resistant design in new construction of multifamily, commercial, and other large buildings.
SGM-MFLB-2023
The consensus standard for soil-gas mitigation in existing multifamily and large buildings, the retrofit counterpart to CC-1000.
