Get Help with Wastewater Management
from Dan’s Pre-Cast Ltd. in Duncan

Dan’s Pre-Cast Ltd. has provided concrete products for contractors, registered wastewater planners, engineers, hospitals, parking lots, and homeowners throughout Vancouver Island. Based in Duncan, our team will work with you to modify our concrete products to best suit your project’s needs.

With over 40 years of experience in the business, our septic tanks and concrete products are well known for their quality. In fact, the trainer for septic installation, Jim Anderson, who has worked all over British Columbia, uses our products in his training processes.

Our products are created with an old-fashioned wet-mix method. While other companies mass produce their concrete products and use additives for a speedier drying process, we do not. We know that these additives make the product brittle, which ultimately compromises your project’s structure. Our concrete products are more reliable and less prone to cracking.

For many of our products, we will transport them to the installation location. Contact our team today if you have questions about our products or would like to place an order.
