Oak Grove, a new neighborhood located ten minutes outside of Boston, MA needed to pour a pitch over an existing concrete system that was never pitched correctly.
Industrial Companies took on this 23,000 sq. ft. project which spanned over three courtyards. Since this was an outdoor project, each courtyard needed to be pitched correctly to make use of the existing drainage system. Industrial Company's called upon Drytek's services to correct the existing concrete slabs. Each courtyard had four to six drains and our objective was to create the perfect pitch for each drain without disturbing the underlying substrate.
To solve this problem, Drytek 7200 was utilized. Each drain was sectioned off with ramps 2” to 0” with about a 10ft width. Bench marks were set at 2” along the structural walls, and forms were built at 2” on the inner core areas. The Drytek 7200 was applied at 08:00 and by 2:00 P.M. the same day Bitchethane rubber membrane (A Grace Product), a layer of plastic, landscaping paper, soil, and grass were added over the Drytek application. Because of the fast drying nature of Drytek 7200, the rubber membrane was able to be added almost immediately, saving the contractor and customer both time and money.
