DRICORE PRO Concrete Repair Crack Injection Expanding Foam (Step Two) | Polyurethane for Sealing Indoor & Outdoor Cracking in Home, Wall, Basement | Moisture Tolerant, Flows into Small Pits

Bought a house with a floor to ceiling crack in my basement. Turns out prior owners had mortared over the crack instead of sealing it correctly. Upon removing the mortar I found the crack to be substantial in size and knew I would need something that expanded or I would be digging out an entire wall. Yes the product is only about half a tube due to the way the mixing procedure is. I did an 8 foot retaining wall with 3 tubes, however, 4 would have been preferable while I learned the amount. Buy extra when in doubt, return as needed. I used a different product for the injection ports, however, it was set-up in exactly the same manor as what is required by this products instructions. New concrete was applied where needed, and ports were sealed over and mounted. I mixed each tube individually during usage, the solution is VERY runny until it begins foaming which is probably around the 2-3 minute mark so you can inject (with a caulk gun) and seal the ports. I had 7 ports for my wall and split all 3 cartridges between those 7, going bottom to top. I did not go until it came out the top port as my depth was extreme. I did half of the tube load on ports 1-4, then 1/3rd of the final tube on my top 3. Before I was even finished with the 5th port I knew I'd chosen correctly. The product had so much expansion that it crept up the wall from floor level to the new concrete area. The foam found even the tiniest hairline crack and worked its way out, solidifying not soon after all the way to my 6 foot measurement. My wall separation was due to ground movement or settling (enough that rebar snapped so the wall was braced before hand) so I'm positive my depth was from wall to dirt. I have full confidence this is permanently sealed from water and other debris ingress. Clean up was as easy as cutting foam with a knife, removing the ports, and sealing said ports. TL;DR and take away: Work time is short once mixed, have tools and area prepared in advance. Buy extra when in doubt as yes it is only half a tube, this is returnable if extra wasn't used. That being said expansion is DRAMATIC and large, 3 tubes cleared a full size basement wall with a dirt to wall crevice at varying widths of up to the entire port hole size. This is not for finish work like the 1 star video, this WILL find every airhole, pocket and crevice it is exposed to. Works great for sealing deep cracks in basements or areas that need to be water tight. This does require the epoxy mounted injection ports.

Worked very well and mine came with the applicator. Is very messy so be ready.

Worked as expected. Had to purchase since 1 tube was not sufficient to fully fill an 8 ft foundation crack.

Works as advertised

I purchased this product last year. I haven’t had the time to write a review but when using this product it’s literally like water. It dropped down the whole wall… it starts to foam after around 3-5 minutes… the worse part, ITS YELLOW! Not grey like in the online video and images. I don’t know if I got a bad badge but it ruined the stone wall. I don’t even know how to remove it.

This product is great for sealing cracks in your foundation.

Easy to inject and mixed well but, consumes quickly.

I feel like there was hardly any product...

Product did do what it was projected to do. Make sure you know the thickness of the wall or item you are planning on using this product for. If your wall it thicker than 4" and taller than 4 ft buy an extra tube. Our wall was 4 inches thick by 4 feet and the product did not go to the top of the wall. Also when purchasing the directions on DryCore show a product with a two tube injection system. Amazon showed a one tube injection system so was a bit confusing. We used the one tube and it was okay. The foam said to wait till it mixed, well only had one tube so what was it to mix with. Hoping it stays till the summer and we can reseal the outside. For now no leak, fingers crossed it stays that way.
