Swimming pool crack repair technology has improved significantly since the introduction of composite repair methods. Structural cracks are commonly found in cement-based pools in areas with heavy ‘freeze-thaw’ climates such as the Mid-West. If not permanently repaired, cracks through your pool shell allow chemically treated water to reach reinforcement steel and degrade the integrity of the pool structure.
The INTER-GLASS® crack repair system solves the problem of what to do with aging acrylic and metal panel wall pools in addition to cement-based pools. Cracks between the panels are permanently bridged, creating a strong one-piece surface that looks and acts like a concrete in-ground pool.

The first phase is to prep the pool’s interior surface. The type and extent of preparation depends on the type of pool construction, condition of the pool surface, whether the pool is painted, or whether the PVC liner must be removed.
Injection ports are inserted into the large cracks and injected with a firm epoxy, filling the cracks entirely. The remaining exposed straws are cut off to create a flat, uniform surface that is flush with the existing concrete shell.
Cracks are then covered in either biaxial, multi-axial, or Kevlar (by Dupont) fabrics which are applied to the surface with special resins, the type of which depends on whether the composition of the pool shell is metal, cement, or fiberglass. This Protective Barrier System bonds to the pool shell creating a water-resistant seal that provides the greatest strength, flexibility, and permanence.
After the resin has cured, INTER‑GLASS® is applied over the repaired crack areas in the selected color. This step smooths and seals the reinforced joints, creating a uniform surface and completing final preparations before INTER‑GLASS® is applied to the entire pool interior.
During the winter months a tent is put in place around the pool protecting its surface from the outside conditions during renovation.
