Crack Repair

- There are two types of swimming pool cracks:

• Structural:             Crack penetrates gunite structure and water leaks through crack to earth (& visa versa).
                         These can be in the wall, in the floor, or both. Occasionally I see them in spa and love seats.
                                    The most effective way to repair a structural crack is to inject a resin epoxy into the crack to fill
                                    the voids and bond the concrete together. Epoxy strength is 13,0000 PSI, much stronger than the
                                    original gunite concrete. We need to drain the pool for the procedure . This process is highly effective.
                                    A second option is to fill the crack with plaster. If the structure moves no more, the plaster covers
                                    the void and seals the crack from leaking. This repair is done underwater. It is not as effective
                                    but less expensive.
  
   

• Non-Structural:      Crack only on plaster surface. Does not penetrate structure and does not leak water.
                                We fill the crack with plaster. If the structure moves no more, the plaster fills the void
                                    and seals the crack from leaking. This repair is done underwater.

- We also repair cracked concrete other than in swimming pools.
                                        If you have concrete that is leaking water, we can inject a resin epoxy or an expanding foam into
                                       the voids to eliminate the leaking.
                                       Common applications are leaking basements, concrete walls, parking garage walls, etc.
                                        If the concrete has rusting reinforcing steel (rebar), we can remove rusted rebar and restore
                                        the concrete as well.
