Replacing theater floor Feel free to flip me to other threads on this one. We do nine shows a year, two are big musicals. The performance space is about 600 sq ft. Our small theater is in a basement which appears to never have had a really good slab floor (in my opinion). We do nine shows a year, two are big musicals. It seems to be built upon some cunchy slab of unknown and varying thickness, a layer of ¼ hardboard and then lino. and then, 40 years ago, on top this, was installed a 4 mil vapor barrier, 2x2” true sleepers, ¾ ply and then 3/4 Oak. We sometimes cover with ¼ hardboard, but not for dance. The floor is solid in some places but mush in others. It is time and we have some money. Dancers seem more concerned with stability than a fully sprung floor. We will seek professional help, but we are looking for practical experience. Assume they rip down to dirt and pump in 4” reinforced slab……..our default surface (from two contractors) is weather barrier, 2x4 sleepers(flat), ¾ ply and ¾ HW finish. We may not have room for more than this as we have to integrate/level with the seating and wing floors which are perfectly flat. ( we are three sided). Any recommendations?
