Concrete Pool Base Aggregate
When it comes to building in-ground vinyl-lined pools, a strong, smooth, and durable pool base is essential. Specialty Vermiculite CPBA is the ultimate solution—a precision-mixed blend of expanded vermiculite granules and exclusive additives that deliver unmatched ease of use and superior results.
What is CPBA?
Specialty Vermiculite CPBA is a specially formulated pool base aggregate designed for effortless application and long-term durability. Its lightweight, chemically inert, and non-abrasive properties make it the preferred choice for professional pool installers.
When mixed in the recommended proportions with Type #1 Portland cement and water, CPBA creates a smooth, creamy mixture that trowels effortlessly into place. The result is a porous, resilient, and long-lasting pool bottom that protects the vinyl liner from abrasion and indentation, enhancing the pool’s beauty and extending its service life.
Key Benefits of CPBA
Easy Installation
Easy Installation- CPBA forms a light, creamy mix that is simple to handle and trowel.
- Ideal for steep side walls—its superior adherence to the substrate makes challenging installations a breeze.
- Handles and trowels with far less effort compared to sand or sand concrete thanks to its low density.
Exceptional Porosity
- Millions of microscopic pores allow moisture to pass through, reducing the risk of base washout in areas with fluctuating water tables.
Non-Abrasive Surface
- Unlike sand or sand concrete bases, CPBA won’t act like sandpaper on the underside of the vinyl liner.
- Protects the liner by creating a smooth, textured surface that minimizes wear and tear.
Resistance to Imperfections
- CPBA is firm and resilient, preventing the formation of pockets, footprints, or indentations on the pool floor.
- Keeps liners smooth and in pristine condition for longer periods.
Long Service Life
- Chemically inert and inorganic, CPBA will not mold, decay, or deteriorate even with constant exposure to moisture.
- Ensures the longevity and structural integrity of the pool base.
