Method for concrete crack repair

A method for repairing an open shrinkage crack in a concrete slab employs expansive mortar. A saw cut is created next to the shrinkage crack, and then expansive mortar is applied into the open saw cut. The expansive mortar material gradually expands and urges the saw cut apart. This shifts the portion of the slab between the saw cut and the slab in the direction to close the shrinkage crack tightly. The expanded mortar material is removed from the saw cut and a rigid spacer is installed in the saw cut. An adhesive can be installed between the two sides of the crack. The surface of the repaired slab can be given cosmetic repairs, and let dry before applying a sealer.

Repair system and method for fiberglass boats

A method to repair moisture damaged wood core boat hulls remotely identifies and repairs all wet core hull areas and optionally performs preventive maintenance on dry hull areas to restore the integrity of a fiberglass boat hull and prevent new water infiltration damage to a boat hull. The wet area repair guidelines using a surface moisture mete Any balsa cored area reading 15% or above is considered a wet area. Any wood cored area reading 20% or above is considered a wet area. The repair steps involves removing all through-hull fittings or hardware. Wet core areas are then dried out using heat lamps, lights or heaters, hot-vac systems, or octopus vacuum with grid system. If necessary, any area not drying out is de-cored and repaired accordingly. After repairs are finished, all through-hull fillings or hardware is reinstalled using new sealant.
