How the U.S. Army Corps of Engineers Cut Weeks of Labor on Dam Grouting

When an 800-foot hydraulic dam project faced severe delays from hardened chemical grout, sacrificial surface protection eliminated mechanical scraping, recovered critical scaffolding labor, and delivered project completion ahead of schedule.

USACE Oklahoma Dam Slide Gate Epoxy Grouting

During an extensive civil rehabilitation project on an 800-foot dam in Oklahoma, the U.S. Army Corps of Engineers installed heavy slide gate channels that required structural two-part epoxy grout for permanent bonding. High-elevation operations required civil crews to work from suspended scaffolding positioned across the face of the dam, mixing two-component epoxy batches on portable 16" × 22" plastic palettes before troweling the mix directly into the gate channels.

The rapid curing profile of two-part structural epoxy quickly triggered a major jobsite bottleneck. Unapplied resin bonded directly to the working surface of the mixing palettes within minutes, cross-linking into a rock-hard matrix that traditional solvents could not dissolve.

The Problem

Hardened epoxy bonded to the plastic palettes created an immediate maintenance roadblock on the scaffolding. Technicians were forced to spend hours chipping and scraping cured epoxy from the palette surfaces before fresh batches could be mixed, or discard the ruined boards entirely. The cycle consumed productive shift hours, generated recurring tooling replacement costs, and threatened to add weeks of delayed labor to the federal project schedule.

Solution

TearOff Products supplied custom-dimensioned 16" × 22" multi-layer protective film stacks engineered to mount directly over each plastic palette. The 4-layer configuration provided an impervious chemical boundary layer that received the mixed two-part epoxy without degradation. Once technicians transferred the batch to the dam channel, the top film layer was peeled away in two seconds, removing residual cured epoxy and presenting a clean, non-stick surface ready for immediate re-batching.

Results

Zero Tool Scraping: Workers peeled away cured resin in seconds without chiseling boards or using aggressive solvents on the scaffold.
Tooling Preservation: The underlying 16" × 22" plastic palettes were protected from resin adhesion and reused indefinitely.
Labor Recovery: Eliminated lost cleanup downtime, cutting weeks of unproductive manual scraping hours off the master schedule.
Budget Performance: Prevented repeat board purchases and delivered the slide gate channel grouting phase ahead of schedule and under budget.
