Polyurethane Concrete Leveling

Also known as poly jacking This method is a process that involves using a high-density geotechnical foam that chemically expands to raise and stabilize your concrete slabs. 

We first drill a hole in your concrete floor. Then, we inject the polyurethane into the hole where it will activate, expand, and fill the void underneath the concrete. In doing so, it can raise uneven concrete slabs, thereby stabilizing them and filling the gaps between the floor and the soil. 

Due to the fast and efficient nature of this method, it’s ideal for heavy, large, and sensitive slabs. It also works for concrete surfaces that need immediate fixes. These include roadways, driveways, sidewalks, etc. 


our polyurethane concrete leveling services also cater to:

  • Basement floors
  • Porches
  • Bridge approaches
  • Warehouse floors
  • Pool decks
  • Patios
  • Steps and stairs
  • Parking lots
  • Railroad crossings

New Concrete Construction

If you want to create a pathway, patio, sidewalk, etc. for your home or commercial space, we at Maryland Concrete Leveling also offer new concrete construction solutions. 

To do this, we must first inspect the site to plan out our course of action. Then we’ll prepare the site by making sure that the soil is compact and well-drained. In doing so, we need to excavate the site, level the soil, and compact the ground. This will allow the concrete to pour more evenly throughout the surface to minimize the possibility of developing cracks in the future. 

When the base is set, we can start pouring our concrete and wait for it to set and cure. Curing in concrete construction is essentially the process where the concrete preserves its moisture to enable the chemical reactions between it and the water to take place. The result can increase the strength of durability of the concrete to ensure a long-lasting lifespan. 

While the curing process can depend on the size and type of concrete used, the average time it takes for new concrete construction to dry is between 24 to 48 hours. After which, the surface should be safe to walk or drive on. 

But take note: Even after the 48-hour mark, the concrete’s drying process is still ongoing. It may take up to 28 days before it completely dries. 


If you’re interested in having a new concrete surface constructed in your residential or commercial properties, contact us at (410) 401-9791. Through our services, we can help you build the following:

  • Sidewalks
  • Driveways
  • Foundation walls (1 to 12 feet)
  • Steps
  • Porches
  • Parking pads
  • Pool decks
  • Basement slabs

Additional Services

For other concrete concerns and queries, Maryland Concrete Leveling also provides additional services, like:


  • Concrete Removal and Replacement: This process involves cutting and removing the deteriorated area of concrete to a particular depth and then replacing it with fresh new concrete. 
  • Polyurethane Crack Injection: Similar to polyurethane concrete leveling, this method is often used to repair minor basement cracks or wall cracks. It involves injecting a foam rubber seal on the crack to fill out the gaps and create a more even layer. 
  • Injection Crack Repair: On the other hand, if you want to repair the other cracks on your home or commercial building’s foundation or walls, you can also opt for injection crack repair. The two injection crack repair techniques we use to ensure the best results are high-pressure injection and low-pressure injection. We often use high-pressure injection when the crack is still active and needs immediate attention whereas low-pressure injection is appropriate for minor cracks that may be inherent to the structures.
  • Concrete Caulking and Sealing: Finally, we also offer concrete caulking and sealing to prevent further damage to the concrete. This is a preventive measure that can hinder cracks from forming on your surfaces.


All of these are designed to help protect your concrete surfaces and enhance your property’s value.
