The CBGSourcing™ 2-Pack Polygem LCR Concrete Crack Repair Kit gives you two complete professional-grade repair systems for permanently repairing leaking and structural concrete cracks. Ideal for larger projects or multiple repairs, this bundle includes everything needed to inject high-strength Polygem LCR epoxy into poured concrete foundation walls, basement walls, retaining walls, garages, and other structural concrete surfaces.
Each kit contains genuine Polygem LCR two-component injection epoxy, surface sealing paste, injection ports with caps, putty knives, mixing sticks, and disposable gloves. Once injected, the low-viscosity epoxy penetrates deep into the crack, creating a structural bond that restores the concrete and helps prevent water infiltration.
Whether you're repairing a single long crack, multiple cracks, or keeping a second kit available for future projects, this convenient 2-pack provides the materials needed for professional-quality results without purchasing components separately.
Designed for homeowners, contractors, and property managers, Polygem LCR has been trusted for concrete crack repair for decades. The complete kits simplify the repair process by providing compatible components that work together from start to finish.
Each kit contains:
Total Contents (2-Pack):
Judy - "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 would purchase again."
Eric Rivera - "Arrived on time, worked great for intended purpose. Only needed to be applied one in basement for a leak, easy to use, adhesive holding great, worth every penny."
Tea - "Parents’ concrete bi/level four foot wall had a big crack when wall was opened up due to buckets of rain water coming in during multiple rain days. We used this product and if you watch the video and do exactly as it says you will be successful. Make sure that you have enough epoxy product if your crack goes all the way through the concrete. They needed three tubes for four feet. Not sure if it will work as it hasn’t rained enough.
R.E. - GREAT PRODUCTS!
Dave L - "If you need to structurally fill a crack in a concrete wall, this is exactly the right product to use. I recommend this product and would use it again."
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."
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."
Robert - "Easy to use and it worked so far."
Lesa - "It sealed my wall great."
Logan - "Product was great overall. Used for a crack in my foundation that was leaking, got a couple of inches of rain days after the repair in the basement. Stay dry."
Cecilia - "Good for small jobs, holds good, and since instructions are simple, you can fix everything yourself. I highly recommend."
Judith - Worked very well. Would definitely buy again."
