Profile: Caro Group of Companies is a manufacturer & supplier of flat roof, and floor drainage products. We offer paving slab support system, flood protection products, and sand & die foundry castings. Our roof drainage outlets ensure a watertight connection between the water & damp proofing membranes and the drainage pipe work, thereby removing the problem of water penetration at this crucial junction. Our spigot roof outlets are available in vertical, 45-degree, or 90-degree versions. These outlets will allow connection to socketed or socketless pipe systems, and seal with any traditional or current water proofing membrane system.
