InterQuad (International Quadratics) 
With a combined legacy spanning over 150 years, International Quadratics (founded in 1976) and Pierce Pool Supplies (originally established in 1898 as A H Pierce) have become well-known names in the Aquatic and Leisure Industry. In 2008, these two companies merged, bringing together Commercial and Domestic aquatic products and services under one roof for the first time.

This merger created a single destination where a diverse range of customers can find solutions for nearly all their aquatic needs. Our knowledgeable staff, supported by a wide array of high-quality furnishings, equipment, and chemicals, ensures this. We continually strive to be closer to our customers, offering essential support and tailored service for the many aquatic products we provide.

Today, we are known as InterQuad and our team is still dedicated to ensuring your aquatic facility operates at its best. We work with aquatic centres, learn to swim schools, fitness and wellness centres, hotels & motels and many more Australia wide. From premium chemicals and pool equipment to expert support, partner with InterQuad for reliable, all-in-one aquatic solutions.
