This might be a question striking your mind. There are so many ways through which you can do the repair of your concrete floor. But you have to finally choose any one of them since you cannot apply all of them at once, it’s practically impossible. From sealants to polyurethane crack injections, you will have several ways to deal with your concrete floors. We will discuss some of the most prominent methods one by one:- 

  1. Sealers And Coatings :

The most common way of going for repair of concrete floors is the use of sealers and coatings. It is one method that you can apply on your own as well. Sealers and coatings can be done quite comfortably. You just need to have basic knowledge of how to apply this material to the floors. While the use of something like polyurethane crack injections might not be so simple, sealers and coatings are something that can be executed comfortably by literally anyone. If there’s any confusion in your mind, you can refer to the manufacturer’s guide. 

  1. Thin Repairs :

If the repair is needed as soon as possible, you will have to quickly find a method to go for concrete floor repair. But choosing the method of polyurethane crack injections might prove to be costly for you. This is why you can choose to do thin repairs. These are generally ¼ to 2 inches deep so you wouldn’t be required to use much of the material here, cutting down on your costs. But these repairs are not supposed to be considered permanent. 

  1. Thick Repairs :

This is another method of going for the repair of concrete floors. As the name suggests, you might have to deal with things in such a manner that you get a permanent solution. You have the option to replace concrete completely, ending all the miseries that you might be facing through existing concrete. You have the chance to go for preplaced aggregate concrete as well. These repairs are generally 3 inches thick. It manages to encompass reinforcing steel from the existing structure. 

  1. Polyurethane Crack Injections :

These work best in the case of the concrete floors which are prone to water. When the concrete floor cracks up, it can cause huge damage to the foundation as well. This is where polyurethane crack injections come to the rescue. Polyurethane foam resin often takes the help of an activator or accelerator to do the job. Resin and activator would first be mixed here before it is injected to the surface. Polyurethane crack injections might require bigger costs but it can act as a permanent solution, especially to the places where you need to seal active leaks. 
Apart from these options, you can also go for Epoxy injections to do the job. From stitching the cracks to routing and sealing, you will find various methods to do the task. You just have to choose the most suitable concrete floor repairs depending upon the surface!

What is a PU Injection, and Do Your Foundation Walls Need One?

What is a PU Injection, and Do Your Foundation Walls Need One?

Does your home’s walls have cracks? They may need a PU injection. Here’s why.

Foundation walls show signs of cracking all the time. They don’t indicate emergencies. But, if they’re left unaddressed, homeowners can expect to face bigger problems like leakage or wall shrinkages. Since these threats are visible and cause significant damage to homes, property owners feel obliged to invest in repairs.

But, the smart thing to do is repairing wall cracks long before they turn into these bigger problems. Homeowners must find long-lasting solutions that prevent cracks from appearing on their walls ever again. Waterproofing, also known as PU grouting, is one such long-lasting solution.

Here’s why your home’s walls may need a PU injection –

What are Polyurethane Crack Injections?

Polyurethane injection is a widely used waterproofing technique in the construction industry. It involves the injection of a fluid resin called polyurethane into crack walls. Post-injection, water leakage through cracks in the concrete walls stop. The polyurethane crack injection repair solution is very popular amongst homeowners as it’s very low cost.

Water leakage issues can be immediately addressed with a PU injection because these repair processes don’t require too much curing time. Polyurethane is ideal for filling in non-structural cracks (e.g., vertical or diagonal cracks) as it has a very low viscosity. It can expand and take over tiny cracks very easily. The tight seals that polyurethane forms inside these cracks prevent further leakage.

Surprising, after a PU injection, polyurethane will retain its flexibility. It can wiggle inside tight concrete structures while keeping all the gaps sealed. Repair experts typically use electric injection pumps to fill the cracks in concrete walls with activated polyurethane.

Why Concrete Repair Experts Recommend Polyurethane Crack Injections?

The polyurethane crack injection repair method is the most recommended waterproofing process because of various reasons –

  • Giving your wall a polyurethane crack injection will make it more resilient against external damages. This versatile resin is constantly used to coat, repair, and insulate concrete walls.
  • A high-quality polyurethane crack injection can make any concrete structure extremely resilient to external damages. The strong adhesive protects the concrete structures from building movements, sunlight exposure, and moisture damage. These injections are ideal for cracked concrete walls on roofs and balconies.
  • PU injection repair is time and cost-effective. The fast-drying polyurethane immediately seals all small cracks on concrete surfaces. The process is cost-effective so keeping construction costs low also becomes easier for repair experts.
  • After your concrete walls have received a high-quality polyurethane crack injection, you’ll no longer need to maintain the walls.
  • A polyurethane crack injection will flush out all the impurities present in the crack; then, the fluid resin material will expand and fill the voids within the foundation wall’s width.
  • If water comes in contact with polyurethane, it accelerates the curing process. That’s why these injections are widely used in repair projects that involve moisture-damaged concrete walls.

Do Your Walls Need PU Injections?

If your home has a bad drainage system or if the walls in your home aren’t well-maintained, cracks are guaranteed to appear on them. This is especially true for concrete walls and floors in damp areas like basements or balconies. A timely PU injection will waterproof these walls from all types of moisture damage.
