There are many causes of structural damage to a tub/shower unit. The most common cause is hairline cracks. These cracks allow water to leak through the gelcoat/acrylic and breakdown the fiberglass backing that structurally supports your tub/shower. If these cracks go on neglected, they will cause further damage to your unit, and eventually cause structural damage to your house.
Through a combination of foaming and fiberglassing techniques, we will eliminate the movement, restoring strength. This allows us to continue on to the cosmetic repair, sealing your tub/shower and eliminating further water damage.
