• Professional Crack Injection System:Designed for professional concrete crack repair applications, these injection packers create a sealed injection channel for epoxy or polyurethane materials. Ideal for restoring structural integrity in basement walls, foundation walls, retaining walls, and concrete surfaces.
• Effective Waterproof Leak Sealing Solution:Engineered to stop water intrusion at the source, these injection ports allow low-pressure resin injection into deep cracks. Once cured, the injected material expands and bonds inside the crack, forming a long-lasting waterproof seal that prevents basement leaks and structural damage.
• Compatible with Standard Injection Equipment:Works with most epoxy injection pumps, polyurethane injection systems, and manual grout injection tools. Suitable for both DIY homeowners and professional contractors performing small or large-scale concrete repair projects.
• Durable Aluminum + Rubber Construction:Each packer is made of high-strength aluminum tubing combined with an expanding rubber base, ensuring a tight fit inside drilled holes. Designed to withstand high-pressure injection without bending, leaking, or loosening during operation.
• 50-Pack Bulk Set for Multiple Repairs:Includes 50 pieces of 3/8" x 4" injection packers, providing enough quantity for multiple crack repair jobs or large foundation waterproofing projects. Cost-effective bulk pack ideal for contractors, maintenance teams, and property repair professionals.
