The process typically involves the following steps:

  • Identifying the location of the cracks or voids.
  • Cleaning the area around the cracks or gaps.
  • Injecting the PU material into the cracks or gaps using pu injection grouting machine .
  • Allowing the PU material to cure.

It is an essential construction technique that can help improve the stability and performance of various structures. It is a concrete method that uses polyurethane foam to fill in cracks and holes. 

How long does it can last? 

It is a popular choice for many construction projects because it is durable and long-lasting. However, how long it lasts can depend on several factors, including the quality of the materials used and the environment in which it is installed.

Tips on how to apply

PU grouting is a construction method that uses PU (polyurethane) material to fill cracks or voids in concrete structures. The PU material is injected into the cracks using a pump, and then it expands and cures to form a water-tight seal. It is often used to repair concrete floors, walls, and ceilings. It can also be used to seal joints between precast concrete panels.

 When it is properly done, it can provide a long-lasting repair that is not only functional but also aesthetically pleasing. 

Here are some tips for using it: 

– First, the cracks or voids must be cleaned out so that the PU material can be properly injected. 

– Second, the PU material must be mixed according to the manufacturer’s instructions. 

– Third, the PU material must be injected into the cracks using a pump. 

– Fourth, after the PU material has been injected, it will need to cure for the specified amount of time before it can be used. 

– Finally, once the it  has cured, it can be sanded and painted to match the surrounding surface.


It is a process that uses polyurethane to fill cracks and voids in concrete. While it has been used in Europe and Asia for many years, it is popular in the United States.

  • It is easy to apply.
  • It forms a flexible seal that is resistant to water and chemicals.
  • It is used in a wide range of temperatures.
  • It is eco-friendly or an environmentally friendly option, as it does not use any hazardous materials. As a result, it is ideal for repairing cracked concrete.

It’s flexible, and tough, and it is resistant to the chemicals found in marine environments and won’t chip or crack when exposed to UV light. The self-levelling properties of the product allow it to fill in gaps and evenly distribute weight.
