Introducing DIY 30ft Pro Polyurethane Foam Crack Injection Kit

The ultimate repair solution for leaking cracks and joints in poured concrete basement walls and foundation walls.

The high-density polyurethane foam is superior to a superficial filler such as hydraulic cement or caulking. It is not just a cosmetic remedy. It expands to more than 10 times its original size as it is injected from the inside to the outside completely penetrating the wall and seeping into every crack, fissure, and pore of the concrete. The full thickness of the wall is waterproofed which does not shrink in size over time.
Once it expands and sets, the foam retains its integrity, and volume, thereby leaving no room for liquids to seep through the wall cracks, pipe openings, wall joints, and so on. The flexibility of polyurethane foam ensures that the seal it produces is retained despite the ground movements, changes in seasons, and frost movement. An industry approved standard method of leaking non-structural foundation cracks.

  • Spring-loaded applicator frees up the user from having to apply constant pressure during the injection, only occasional pumping is required to maintain the pressure at a max of 50 psi. A great option for larger or ongoing projects
  • Other options include adding extra Polyurethane
  • Link to More #102 Polyurethane More 901 sealing paste More ports,mixers etc
  • This kit can have the number of Standard surface ports vs the number of Corner surface ports changed at no cost just specify on the special shipping instructions on checkout or give us a call at 866-445-3984 after you have made your order.



Easy-to-Use DIY Kit for Semi-professionals

DIY Polyurethane Foam Crack Injection Kits offer a professional-grade solution against water leaks in a poured concrete wall. The kit is so user-friendly that even someone who has minimal DIY project experience can use it. No construction expertise or specialized equipment is required because no exterior digging or excavation is needed for the project. The low-pressure injection process from the inside fills up the cracks, pores, pipe openings, and joints. It’s a very easy and straightforward process to achieve.

This kit offers the same product that professional contractors use to repair leaking cracks. The advantage of this kit is that it simplifies the repair process for the DIYers. All the repair essentials, including the tools, are provided as part of the kit. The user can follow the instructions supplied in the manual and perform the repair with ease without any professional assistance. The result will be as good and secure as that performed by a professional.

Why Cheaper Kits Do Not Work?

The more commonly available concrete crack repair kits on the market do not provide enough material to fill up the crack properly. Also, this type of material by any manufacturer has a limited shelf life and if purchased at a retail location then the age of the material is unknown by the time it is used. NextStar makes sure you are supplied with recently packaged material to extend the use time. Some of the products packaged on the market use a single caulking tube type that have an internal piston to dispense equal amounts of chemical but during this process dispenses much less material then the applicator anticipated. Most of these tubes are 7-9 oz 185 – 250 ml compared to a single professional-grade dual tube which is a full 600 ml. In this case, the retail or universal cartridge will cost you more as you are forced to purchase more product to complete the repair. The use of caulking type materials is simply a temporary patch only and is all that should be expected of them. Using Nextstar professional-grade products for foundation crack repairs will save as the job only needs to be done once. The effective solution against leaking wall cracks is a material that repels water and does not lose its integrity over the years.

Why Polyurethane Foam Crack Injection Works?

This kit is specially designed to offer a lasting solution against leaking cracks in concrete foundation walls. Here are the various reasons why it is more effective than the other options available in the market.

  • Polyurethane foam is hydrophobic. Unlike concrete, it does not absorb or retain water. By filling up every nook, corner, and open space of the crack from the inside, the foam creates a watertight seal throughout the thickness of the wall. There is no room left for water to penetrate, settle, or seep.


  • The high-density foam expands over 10 times its original size and does not lose its volume over time. In other words, the seal it creates is a permanent seal.


  • When the foam cures, it forms a semi-flexible resin. This flexibility preserves its integrity over many decades, despite ground movement and continuous changes in temperatures and seasons. As a result, the waterproofing effect is not compromised over the decades.


When is This Kit Not Suitable?

When you have a crack that requires structural reinforcement, you need an injection material that provides strength and support to the wall. The polyurethane foam kit is not a suitable choice for this purpose. It is designed to offer protection against wall crack water leaks. It does not offer structural strength. In such a case, Nexstar’s Epoxy Foundation Crack Repair Kits would be the ideal choice.
