Polymer Concrete Trench Drain Systems

Cast iron trench drain systems are synonymous with high strength and load-bearing capacity, which makes them an ideal choice for many heavy-duty commercial applications, such as warehouses and parking lots. Because cast iron offers great durability and can withstand high loads, it’s capable of supporting the longevity of the trench drain system in even high-traffic areas. 

The robust nature of cast iron also lends itself to long-term cost savings, as the need for frequent replacements is significantly reduced. In addition, cast iron grates can be trusted to be a secure and stable surface, which is essential in areas where safety is a priority. The aesthetic appeal of cast iron, with its classic and professional look, adds an additional layer of appeal, especially for businesses that value appearance.

Polymer concrete trench drain systems boast exceptional compression strength. This material — a composite of polymer resin and aggregates — offers a superior bonding strength compared to traditional concrete. As a result, the system can withstand heavy loads without cracking or failing when utilized in trench drain systems.

This characteristic is particularly beneficial for commercial applications where high traffic or heavy equipment is common. The enhanced compression strength of these systems ensures they maintain their structural integrity throughout their lifespan and serve as a reliable component of the trench drain system.

Trench drain systems created with polymer concrete exhibit reduced water permeability. This reduced permeability is due to the polymer resin within the concrete, which fills potential voids and creates a non-porous, tightly sealed surface.

Consequently, water and other liquids are less likely to penetrate the surface of the systems — promoting a longer lifespan and reduced maintenance for the trench drain system. This property is particularly advantageous when you need drain systems installed in areas prone to high rainfall. Furthermore, the reduced water permeability of these systems also contributes to preventing subsurface erosion beneath the trench drains, further enhancing system durability.

The resistance of polymer concrete trench drain systems to thawing and freezing cycles is thanks to the material’s low water absorption rate. Since water cannot easily penetrate the polymer concrete, the risk of damage caused by freezing water inside the material is minimized. 

This resistance is vital in environments subject to seasonal temperature variations, where traditional materials may crack or deteriorate under the stress of freezing and thawing. By using polymer concrete for trench drain systems, the longevity of a trench drain system can be significantly improved. This durability is a key consideration for the design and selection of trench drain components, especially in regions where winter weather can be severe.

Polymer concrete trench drain systems offer excellent chemical protection due to the chemical inertness of the polymer resin used in the composite material. This resistance to a wide range of chemicals makes them an ideal choice for industrial and commercial settings where exposure to harsh substances is common.

Unlike systems made from materials like ductile iron, polymer concrete does not react with most chemicals, ensuring that the product maintains its integrity and appearance over time. This chemical resistance also means that the systems require less maintenance and are less likely to need replacement due to chemical damage. As a result, polymer concrete trench drain systems are a cost-effective and durable option for managing surface water while protecting the trench drain system from chemical erosion.
