Kees, Gary . 2004. Maintenance Issues and Repair Guidelines for Precast Concrete Toilets and Utility Buildings. 0471 2334P. Missoula, MT: U.S. Department of Agriculture, Forest Service, Missoula Technology and Development Center. 8 p.

Describes how to repair cracked panels and peeling coatings on Sweet Smelling Toilets. These toilets were developed by the USDA Forest Service with ventilation that carries odors out of the outhouse. Two firms have U.S. Government contracts to make the precast concrete outhouses: CXT, Inc., in Spokane, WA, and Missoula Concrete Construction in Missoula, MT. Although cracks may appear to compromise the structural integrity of the concrete panels, steel bars (rebar) that reinforce the panels prevent small cracks from causing serious problems. A simple guideline from CXT can be used to determine whether a crack is cause for concern. If a credit card can be inserted more than 3/16 of an inch deep into a crack, send a photo of the crack (with a ruler alongside it for scale) to the manufacturer's engineering department or to a Forest Service facilities engineer. Rust stains around cracks or exposed steel reinforcing bars also would be a cause for concern.
