Single-component pumps are great for the busy contractor looking for a time-saving solution for small hairline cracks to be injected with polyurethane. This single-component pump is the most popular of all types of high-pressure crack injection using activated or single-component polyurethane Nextstar dual-component pumps are typically used with two-component polyurethane or two-component epoxy and can be a big timesaver for large projects versus using the cartridge system. These pumps have two components and can be used on different projects on the same day. You only need to clean the valve head and zerk between job sites. Nextstar Single or Dual component polyurethane and epoxy pumps are easy to use and easy to maintain.

High-Pressure Crack Injection is effective

For active leaking basement foundations that have been previously repaired by unapproved methods such as hydraulic cement silicons and any other surface patch material. Usually, these repairs are difficult to identify where the crack is in the concrete because of previous work on the foundation. Vertical cracks that are very small and leaking are also good candidates for this method.

Low-Pressure Crack Injection is effective

If the concrete foundation cracks are easy to see and haven't been repaired before, and they're not actively leaking, the low-pressure method is a good option. This method offers more choices for polyurethanes and epoxies. To use his method, you need to glue surface ports every 8 to 10 inches apart and seal up the cracks between them. This process may take longer, but it won't harm the concrete.

Professional High-Pressure Crack Injection Systems

Nextstar offers two types of High-Pressure injection equipment for busy contractors for those large or difficult injection projects. You can drill and put in High-Pressure Packers on one visit, then start filling the crack with polyurethane right away. Depending on the size of the crack and the type of polyurethane used, you might not need to seal the space between the packers. Nextstar single component pumps are great for the busy contractor looking for a time-saving solution for small hairline cracks to be injected with polyurethane. This single-component pump is the most popular of all types of high-pressure crack injection using activated or single-component polyurethane. Manual hand pumps are another effective method for one-time repairs vs the expense of a dedicated pump. Contractors may not use high pressure that often and may decide on a disposable tool to save time and money. Nextstar dual-component pumps are usually paired with two-component polyurethane or two-component epoxy, which can be a significant time-saver for more extensive projects when compared to using the cartridge system.

With the dual pump systems, they can be used on multiple jobs on the same day, with only needing to clean the valve head and zerk at the end of the day. Nextstar single/dual component polyurethane and epoxy pumps are easy to use and easy to maintain.

Injection materials

It's essential to pick a material that can expand and fill the crack when selecting a product for high-pressure crack injection. Moisture also matters, so you might need to use different resins depending on the situation. NextStar provides various types of polyurethane to cater to different needs. 1 Activated Polyurethane only responds when it gets in touch with moisture, and the response speed can be controlled by adjusting the activator's amount. 2 We also have a single-component polyurethane that can expand at a fixed rate when exposed to moisture. 3 Koster 2n1 dual-component polyurethane solidifies as a hard resin when there's no moisture, but it can foam when it encounters water or moisture.

The integrity and life of a structure can be severely compromised if problems like cracking and leaks are ignored or left untreated. These issues can lead to unwanted leaks and even failure under severe overload or restraint. By using high-pressure crack injection, these problems can be addressed before they become too disruptive and costly to fix. The American Concrete Institute suggests using this method to control leaky cracks reliably and cost-effectively.
