Stratarock High Build Repair is a high-performance, 100% solids epoxy concrete repair mortar engineered for industrial and commercial environments. Designed to restore and protect damaged concrete surfaces, it offers exceptional durability in areas exposed to heavy traffic, mechanical impact, and chemical exposure. Its three-component formulation includes a high-load aggregate for enhanced compressive strength, making it an ideal solution for structural repairs where traditional cementitious patching compounds fall short.

Unlike standard concrete repair products, Stratarock High Build Repair provides fast cure times, superior bonding strength, and long-lasting resistance to abrasion and wear. This heavy-duty epoxy repair mortar is suitable for resurfacing concrete floors, rebuilding edges, and patching vertical or overhead surfaces without the need for formwork. It can be applied from featheredge to full depth, allowing for both minor surface patching and deep structural restoration.

Stratarock High Build Repair is frequently used in industrial plants, warehouses, parking structures, stairwells, and mechanical rooms — any location where fast-setting, chemical-resistant concrete repair is critical. Its extended working time and rapid return-to-service capability help reduce downtime and improve productivity, making it a go-to solution for contractors and maintenance professionals performing epoxy concrete repairs under demanding site conditions.

Where to Use Stratarock High Build Repair: Industrial and Commercial Applications

Stratarock High Build Repair is engineered for critical concrete patching, resurfacing, and structural restoration where strength, chemical resistance, and durability are essential. It is an ideal choice for rebuilding expansion joints, where high compressive strength and abrasion resistance are required to withstand continuous movement and heavy traffic. The product is also commonly used for stair tread and nosing repairs, offering a reliable solution for restoring broken or worn stair edges in commercial buildings and industrial facilities.

In parking garages and loading docks, Stratarock High Build Repair is used to repair concrete spalls, curb damage, and floor surfaces exposed to vehicles and mechanical equipment. Its non-sag, trowel-grade consistency allows for efficient patching of vertical walls, tank chimes, and other upright surfaces without the need for forms. Facility maintenance teams often select High Build Repair for resurfacing worn warehouse and plant floors, where chemical exposure, heavy loads, and operational stress demand a high-strength epoxy mortar that cures quickly and resists long-term wear.

Whether repairing concrete edges, rebuilding damaged curbs, or restoring vertical structures, Stratarock High Build Repair provides a dependable, fast-curing solution that meets the challenges of industrial, commercial, and transportation environments.

Frequently Asked Questions

What is the cure time for Stratarock High Build Repair?

Stratarock High Build Repair allows for foot traffic within 2 to 3 hours at 77°F, making it ideal for projects requiring fast return to service. Full cure typically occurs within 12 to 48 hours, depending on site temperature and humidity levels.

Can Stratarock High Build Repair be used for vertical or overhead repairs?

Yes. The non-sag, trowel-grade consistency of Stratarock High Build Repair makes it an excellent choice for vertical and overhead concrete repairs. It can be feathered or built up to full depth without the need for additional formwork.

What surface preparation is required before applying Stratarock High Build Repair?

Concrete surfaces must be clean, sound, and properly prepared through mechanical means such as shot blasting or grinding. A rough surface profile is critical to ensure strong mechanical bonding. Stratarock recommends the use of Stratarock Epoxy Primer WB to maximize adhesion prior to installing High Build Repair.

How should Stratarock High Build Repair be mixed and applied?

Mix the pre-measured Part A (resin) and Part B (hardener) thoroughly for two minutes before gradually blending in the 40-pound bag of filler (Part C). Continue mixing until the material reaches a uniform consistency. An electric paddle mixer is recommended for efficient blending.

What are the recommended installation temperatures for Stratarock High Build Repair?

For best results, surface and ambient temperatures should be between 60°F and 90°F during installation and curing. Installing outside of this range may affect working time and cure performance.

Is Stratarock High Build Repair resistant to chemicals?

Yes. Stratarock High Build Repair offers excellent chemical resistance against a wide range of industrial chemicals, oils, and solvents. For specific chemical compatibility information, contact Indcon for a detailed chemical resistance guide.
