D&L - Fiberglass Tanks
D&L Concrete & Fiberglass Products Ltd. specializes in the manufacturing of fiberglass composite tanks leveraging high-quality raw materials. The company does not employ mineral fillers in their resin formulations, a common cost-reduction approach involving calcium carbonate dust used by some manufacturers. This practice significantly reduces the fiberglass resin's ability to saturate, resulting in a weaker and more brittle final product. Instead, D&L prioritizes high fiberglass content in their products to ensure maximum strength, durability, and toughness. Additionally, D&L employs a bonded unibody design for their tanks, using top-quality polyester resins and fiberglass to create a completely sealed, seamless structure. By eliminating the use of gaskets, flanges, and bolts, D&L reduces the risk of gasket failures and ensures a structurally superior tank. They offer various models and sizes of septic and holding tanks, catering to both residential and commercial uses.
Filled vs Unfilled Resins
At D&L, we manufacture of our fibreglass composite tanks using top quality raw materials. We do not use fillers in the production of our tanks. “Filled” resin is used by some manufacturers in order to reduce to cost of the materials. This process involves mixing calcium carbonate dust into the resin. While inexpensive, this dust reduces how much fibreglass the resin can saturate, so the finished part contains less fibreglass. Lower fibreglass content results in a less tough, more brittle part.
At D&L, we do not “fill” our resin. This results in a finished product with high fibreglass content for maximized strength, toughness, and durability.
Bonded Unibody Design
Some Manufacturers of Fibreglass tanks use gaskets, flanges, and bolts to assemble their tanks. At D&L, we bond the tank components together with the same top quality polyester resins and fibreglass that the parts are fabricated from, resulting in a completely sealed, structurally superior seamless tank. Our process of bonding the tanks eliminates the chance of gasket failures.
