If the floor of your fiberglass shower unit has developed cracks. 
Or if leaking has occurred because of those cracks, an inlay can be installed that will fix that problem.

When a Fiberglass shower unit is installed in a home during construction, it is attached to the surrounding 2x4 wall studs, and supported underneath with a frame built also using 2x4's. 

Over time, the floor of the shower may weaken, if the floor supports are too far apart.  Surface cracks may develop on the edges of the supports, or an actual break may occur in the floor causing water to leak to rooms below.

The solution: Custom fit Floor Inlay. 

Visual inspection by a technician is necessary, at which time measurements will be taken to ensure a proper fit.

The inlay is installed using a two-component epoxy glue that "welds" itself to the surface of the shower unit.

The surface will never leak again, it will never crack, and your floor will be stronger than before.
