Frequently Asked Questions

WHAT IS GUNITE?

Gunite is a specialized concrete application method used in pool construction and structural projects. Unlike traditional concrete, which is mixed with water before application, gunite is a dry mixture of cement, sand, and fine aggregates. This dry mix is delivered to the job site in specialized trucks and then pneumatically conveyed through a hose at high velocity. Water is introduced at the nozzle, allowing for precise control over the consistency and placement of the material.

  • Gunite is a dry-mix process where dry cement and sand are mixed and pneumatically projected through a hose with water added at the nozzle.

  • Gunite is a dry-mix process where water is added at the nozzle, while shotcrete is a wet-mix process where water is pre-mixed with the concrete before application. Gunite offers better control over water content, making it ideal for complex shapes and structural integrity.

  • Gunite requires at least 28 days of proper curing to reach optimal strength. Moist curing (spraying with water multiple times a day) helps prevent cracking and ensures durability.

  • Gunite itself is not waterproof, but it becomes watertight when finished with interior finish, tile, or other coatings. Waterproofing additives and proper sealing are essential for pools and water-retaining structures.

  • Gunite pools are highly durable, customizable, and can be shaped into virtually any design. Unlike pre-formed fiberglass or vinyl pools, gunite pools offer a long lifespan and can be resurfaced if needed.

  • Clear the area

    • Remove all personal items: patio furniture, planters, toys, or decorations near the work zone

    • Protect landscaping: Cover or temporarily relocate delicate plans and shrubs. Gunite dust and overspray can damage them.

    Understand Overspray and Dust

    • Overspray is common: The high-pressure application can lead to material getting on nearby surfaces, especially in windy conditions.

    • Expect dust: Fine cement dust can spread around the yard and even onto nearby structures.

    Be Aware of Noise and Timing

    • The gunite process is loud and can take several hours to a full day, depending on the pool size.
