Acousti Engineering Company of Florida has been helping our general contractors and corporate end users remedy poorly placed concrete for the past 5 years. During this period we have poured cementious underlayments and gypsum based leveling products over crowns, bird baths, and a host of other properties associated with defective substrates. We represent Bostik Findley, Mapei, and USG Levelrock. These underlayment material manufacturers allow us to remedy substrate problems for any budget.
