Polyurethane Foam Crack Injection

Concrete Cracks

Cracks in concrete caused by shrinkage are a common foundation problem. Cracks due to shrinkage and are easy to detect, since they almost always extend through the full thickness of the foundation wall. Unfortunately, such large cracks also indicate a path for water entry. 

Where Cracks Most Commonly Appear

Common areas for cracks in concrete due to shrinkage are above a doorway, under your basement windows, or around the middle of a large poured concrete wall. Cracks above doorways indicate that the foundation has "stepped down." As soon as cracks form in your basement or crawl space wall or floor slab, water has the perfect pathway to your basement, right through these cracks. 

How to Treat Your Crack Problem

Although the unfortunate case often occurs where concrete control joints are not put in place in residential construction, there are a number of ways to take care of leakage due to cracks. Atlas Restoration has a quick, easy, and effective solution to this grave problem. Our most-used repairing solution includes injecting of liquid polyurethane, which forms into foam into the cracks. Injecting in liquid form enables a gentle and slow filling treatment of the basement crack that will fill the crack completely and quickly. In just a few minutes, the polyurethane liquid react with the water in the crack and begins to foam. In fact, water is the exact element that changes the liquid into foam. 

After the liquid forms into a foam, it restricts water from leaking into the cracks. The foam is effective enough to fill voids in the soil outside the basement as well. The strong bond formed by this foam to concrete is strong enough to tolerate even the most severe pressure caused by heavy rains and faulty roof runoff systems. forms a strong bond to the concrete. High underground or "subsurface" water levels are typically caused by heavy rains and most-often by faulty roof runoff systems. 

Polyurethane Injection Has the Following Advantages

  • Ensures a more permanent solution than all other crack patching methods
  • Repair occurs only on the inside of the basement wall, creating much less mess from repair
  • Quick repair process that effectively halts water leaks. 
  • Complete confidence that your possessions will be safe from water, and your basement free of water leakage. 


What Makes Our Backup Sump Pumps So Unique?

At Atlas Restoration, we know the importance of location for back-up sump pumps. Our pumps, unlike most others used by repair companies, are positioned outside the sump water. Positioning the backup pumps and floats outside the water prevents constant exposure to problematic elements such as mud, debris, and unclean water.

Where Other Repair Techniques Fail

A common mistake made in backup sump pump installation is their position above the main sump pump. Moreover, many of the average backup pumps often not have a suction pipe. They drain the sump pit's water only partially, creating more frequent starts, less durability, and shorter pumping cycles.

Another kind of error is the installation of a second pump inside a small pit. The problem here? This faulty repair will likely result in the trapping or entangling of primary or secondary floats, leaving both pumps not functioning properly, or not functioning at all. 

And yet another problem common to conventional backup sump pump installation methods is the positioning of the backup pump inside, or directly above the main sump pump. As a result of this faulty installation, your sump pump's primary check valve is just inches above the main pump, open to heavy turbulence and endless fluctuations in pressure. This kind of stress on a check valve will cause breakage or holes in the valve, leading to the recycling of water through the main pump, straight down into your sump pit, and right into your basement. 

Advantages of Atlas Restoration's Battery Backup Sump Pumps

  • Complete security and extended longevity of the backup system
  • No interference with your home's primary pump or its float.
  • A slim-line vertical float switch eliminates the danger of a stuck float inside a crowded sump pit.
  • The suction pipe of our back-up pumps reaches to the bottom of the sump pit, so that it can fully empty the pit in each cycle.

How Do I Know If My Drain Tiles Are Working Properly?

Since your floor's footing tiles are not visible and typically cannot be adequately seen by a sewer camera, the only sign that they are working properly is if seepage through the floor, or around the floor/wall joint is detected. If such seepage occurs, and your sump pump is working, then your drain tile system is not.
