Epoxy Repair Kits (Solution-Based)

All-In-One Structural Repair Systems

Stop foundation leaks and restore structural integrity with our project-ready repair systems. Engineered for high-success DIY application, these kits utilize professional-grade Polygem LCR materials to create a permanent, 7,908 PSI structural weld.

What’s Included:

  • Industrial Resin: 100% solids, moisture-insensitive epoxy.
  • Injection Hardware: Professional surface ports with integrated caps.
  • Anchoring Paste: High-modulus sealer paste to secure ports and seal the crack face.

Ideal For: Vertical basement wall cracks, pool deck fissures, and concrete slab restoration.

Injection Epoxies & Resins

Professional Injection Resins & Refills

Our flagship Polygem LCR resins are 100% solids, two-part structural epoxies designed for deep-fissure penetration. Featuring an Ultra-Low Viscosity (580 cps) formula, these resins seek out internal voids in cracks as narrow as 0.005 inches.

Technical Performance:

  • Structural Strength: 7,908 PSI compressive strength (ASTM D-695).
  • Versatility: Moisture-insensitive formula cures on damp concrete or underwater.
  • Compatibility: Refill cartridges fit standard 10 oz caulking guns.

Use these for gravity-fed horizontal repairs or as refills for vertical injection projects.

Injection Ports & Hardware

Injection Ports & Anchoring Pastes

The essential hardware required for professional-grade vertical crack injection. Our high-flow ports are designed to straddle cracks up to 1/8" wide, providing a secure entry point for structural resins.

Hardware Essentials:

  • Surface Ports: Designed for flat-wall foundation repairs.
  • Corner Ports: Specialized angled bases for inside-corner crack injection.
  • Setting Pastes: High-strength LCR Crack Sealer Paste used to anchor ports and seal the crack face before injection.

Tools & Preparation

Bulk & Contractor Packs

Contractor-Scale Volume & Multi-Packs

Value-engineered for professional contractors and large-scale residential projects. Our 3-packs, 6-packs, and wholesale cases ensure you have the material volume necessary for continuous, uninterrupted injection on deep or extensive cracks.

The Bulk Advantage:

  • Reduced Cost-Per-Unit: Wholesale pricing on LCR cartridges and port packs.
  • Project Efficiency: Eliminate the risk of running out of material mid-injection.
  • ASTM-Verified Consistency: The same 7,908 PSI material used on industrial jobsites.

Michael J Nilles - "Stops leaks! Easy to follow directions. Used this many times for different friends repairs. Never failed."

Alexkuzh - "easy to use - I repaired wide cracks, length 10ft width up to 1\8. Two cans of resin were enough to seal, but I had to buy 3 bottles of liquid resin and 7 plastic injectors, because the crack was deep and long. Very easy to use. Saved a lot of money. I solved my problem. Thank you."

Ken Enneking - "

I did a lot of research before I chose this brand. It is easy to work with. The best feature is that they include the 2 parts of the epoxy in the one tube and you never have to touch the epoxy that goes into the wall. The grey epoxy that you mix to put on the wall surface, comes with far more than needed. I was able to glue 16 feet worth of crack with one kit. By the 2nd repair I was getting complements saying I was a pro."

R.E. - GREAT PRODUCTS!

thomas c - "Great product - Easy to apply and great coverage."

Maria A . - "This product goes on thicker - Whether small or large cracks, this mixture of A & B works well. It is thicker but still goes on cement walls, floors indoors or outdoors area of concrete. Heads up! This product is not made to pour as some products do."

Customer - "It worked as expected - I have a system for fixing cracks in basement walls. I have more solution than the epoxy that comes with the kit. The company did not sell the epoxy by itself. So, I looked online for something that would do the same job. It did not cure as fast, but it worked perfectly. Just wait a day before filling the cracks through the nipples."

Allen Crossley  - "Good injection system - Follow directions, I used their instruction video, and all worked out well."

The Beetle - "Came quick - ready to roll! - Grab some for that special project!"

ed - "Works as expected - I ordered this to apply on a 1/4" crack on the exposed foundation in my garage. The crack runs through the entire wall which is about 1' high. I covered the rear of the wall with cardboard so that the epoxy would not leak out the back. I inserted 3 of the injection ports into the crack and covered the rest with cardboard. Using my caulking gun I injected the epoxy mix into the ports starting from the bottom port. The smell from this is pretty strong so I had a fan blowing air across my work area. I let this sit for a couple days before removing the carboard. The epoxy worked in filling the crack and feels solid."

Judy - "This works great! - We applied this to a crack in our basement. It is the best thing we have found for sealing a crack in a wall. Would definitely recommend this for problem in basement wall!"

PSC - "worked great - Worked great would purchase again."

JT - "I followed up a few days later with LCR Epoxy Repair Paste applied around all the lines and in the cracks. This thick epoxy paste should block the rising water. It is a very thick, grey 2-part epoxy paste.  It can be smoothed out with a finger or tool dampened with water. Tools can be cleaned with water if done before the epoxy cures. It also has a chemical smell which is not nearly as strong as the clear epoxy from the tube."
