Abstract
The present invention is a method of making a backerboard having a fiberglass mesh on one side, and an impervious reinforcement membrane on the other side. The backerboard incorporates a low density, high compressive strength concrete core having an upper principal surface and a lower principal surface. The upper principal surface of the core is covered by a fiberglass mesh reinforcement layer, itself covered and bonded to the core by a thin layer of Portland cement. The lower principal surface of the backerboard is covered with a high tensile strength, impervious reinforcement membrane.
Claims31
A method of manufacturing a construction element for use as an underlayment or backerboard, the method comprising:
- depositing a core material from a core material hopper onto an impervious membrane;
- and
- disposing a reinforcement mesh onto the core material, the reinforcement mesh forming a top surface of the construction element, the impervious membrane forming a bottom surface of the construction element.
A method of manufacturing a construction element for use as an underlayment or backerboard, the method comprising:
- conveying a continuous sheet of impervious membrane through a core station;
- and
- depositing at the core station a core material onto the impervious membrane prior to applying a pervious membrane.
A method of manufacturing a construction element for use as an underlayment or backerboard, the method comprising:
- conveying a continuous sheet of impervious membrane through a core station;
- and
- depositing at the core station a core material onto the impervious membrane;
- wherein the core material comprising randomly dispersed chopped alkaline resistant fibers.
A method of making a construction element, the method consisting essentially of:
- depositing a cementitious substance directly onto a layer of impervious non-adhesive non-cementitious reinforcement material;
- and
- placing a layer of pervious non-cementitious reinforcement material only atop the cementitious substance.
