CrackWeld Concrete Floor Crack Repair Kit – 4 Pack

High-Coverage Concrete Slab Repair for Basement Floors, Garages & Driveways

The CrackWeld 4 Pack Concrete Floor Repair Kit is designed for larger crack repair projects where strength, speed, and coverage matter. This expanded kit delivers professional-grade results by using a two-part rigid polymer that chemically bonds fractured concrete back together, curing within minutes to a strength that exceeds the original slab.

Engineered for basement floor cracks, slab-on-grade foundations, garages, driveways, industrial floors, patios, pool decks, sidewalks, and parking structures, the 4 Pack is ideal for multiple cracks, long runs, or wider defects, especially in areas exposed to water intrusion, radon gas, and heavy surface traffic.

Structural Crack Repair That Seals and Stabilizes

Concrete floor cracks are more than cosmetic; they allow water and soil gases like radon to migrate through the slab. CrackWeld’s penetrating, non-shrinking polymer flows into the crack, locking the concrete together while forming a tight seal against water seepage and gas entry.

• Helps seal basement floor cracks against water intrusion

• Reduces radon gas entry through slab cracks

• Cures rapidly to a rigid, load-bearing repair

• Designed for long-term durability in high-stress areas

No Saw Cutting, No Routing, No Guesswork

CrackWeld simplifies concrete crack repair by eliminating unnecessary prep work.

• No routing or grinding required

• Low-viscosity formula penetrates hairline cracks

• Stabilizes crumbly edges and stress fractures

• Fills spalled areas, voids, holes, and surface defects

• Fast cure minimizes downtime for homes and facilities

4-Pack Coverage for Bigger Projects

The CrackWeld 4-Pack provides additional material for:

• Multiple basement floor cracks

• Long garage or driveway cracks

• Commercial or industrial concrete floors

• Parking garages and high-traffic slabs

Each kit includes all required components; just add a standard caulking gun or use your own.
