Gypcrete is a lite weight cement mix which uses gypsum instead of sand and a high quality Portland mix making gypcrete.
In commercial applications Gypcrete is used as a sound deadener and a fire retardant between floors.

In a residential setting it is normally used to cover over infloor water heat pipes.

The gypcrete companies can pour the gypcrete at a minimum of 1/2”. A good thickness is 1” or more, this includes pouring over all types of pipes. (know this there is no law to protect the homeowner about gypcrete). Gypcrete must have a load bearing floor under it to support it, and the finished floor and it live load (furnishings and people). If you are installing the gypcrete 1 1/2 or less – it must bond to the structural floor below. If you need insulation under the gypcrete, install the insulation than install 4’ x 16’ wire panels with 6” x 6” grids anchored to the floor below the insulation with the anchor not less than 2’ square on center. The wire mesh helps stabilize the gypcrete and keeps it from braking up in the future.
