Trench Drain Joint Sealant

Expansion and Contraction Management

In long runs of trench drains,expansion joints are necessary to account for temperature fluctuations and material movement.

These joints should be placed at the ends of a trench run rather than within the drain itself.

If movement joints must pass through a trench drain, placing them at a bell-and-spigot joint allows controlled movement without structural compromise.

A bond breaker is used behind the trench joint, with a flexible urethane sealant applied to maintain a watertight connection

Chemical Containment

Industrial and commercial applications often require trench drains to resist chemical exposure

The more chemically resistant a sealant, the less flexible it typically is

Some chemicals cause minimal damage, while others aggressively degradestandard trench drain materials and sealants.

To maximize durability, minimize movement in the trench drain systembyreinforcing concrete encasementand ensuring stable soil compaction toprevent shifting.

Flexible Sealants-For Movement and General Water Resistance

Ideal for sealing joints in trench drains exposed to water, oils, and light chemical exposure.

Best suited for automotive shops, fire stations, kennels, and general-purpose drainage applications.

Urethane-based sealants provide high adhesion and flexibility, ensuring effective sealing in areas with slight movement. without structural compromise.

Rigid Sealants-For High Chemical Resistance and Structural Integrity

Used for permanent, watertight joints in environments where flexibility is not required.

Composed of fiber-reinforced polyester or vinyl ester resins, these sealants provide superior chemical resistance.

Applied in heavy-duty industrial environments, chemical processing plants, and areas where secondary containment is required.
