"My experience with Liberty Concrete in the removal and replacement of a 2,300 Sq.Ft. driveway area was a very positive. From the initial estimate through the entire construction process the work was done efficiently. I was kept informed of the work schedule and any questions I had were promptly answered. I was impressed with the quality and attention to details done during the grading, gravel sub-grade work, curb forming and the final pouring and finishing of the curbs and driveway. One third of the project involved a moderately steep slope intersecting a steeper city street at an angle. The entire project area required careful calculation to obtain the proper drainage and alignment. The final project aligns perfectly. The runoff from six inches of snow soon after project completion demonstrated that everything drained well! I would strongly recommend Liberty Concrete if you are considering having cement work done. Their prices are competitive and the quality of their work is superior!"

"I have a property that one out of the four concrete pads in the driveway had sunk. The tenant thought it could cause a tripping hazard so I contacted James and he went out there in one day with his crew and remove the concrete and repoured the concrete pad, making it level. He matched the concrete pad with an aggregate finish, and it looked like it did when it was new they were very professional and cleaned up after themselves and the tenant was very happy."

Foundation Drain Installation FAQs, answered by experts

Yes, you can add a battery to your existing sump pump. There are batteries available that can be plugged into your existing system; however, most battery backups come as a complete system and act as a replacement for your existing sump pump.

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites

Not all window wells have a formal drain, but they all require a method for water to flow away from the window. Some wells are connected to an interior or exterior drain tile, which is the most effective solution. Others rely on a deep layer of gravel or crushed stone that allows water to filter down into the soil.

However, if a window well lacks a proper drainage system, it can lead to basement seepage, costly water damage, mold growth, and potential foundation damage. This is especially true in areas with heavy rainfall or expansive soil.

If your window well doesn't have a drain or is not draining quickly enough, you have a few options. For gravel-based systems, the stone may have compacted and needs to be improved. For a more robust solution, you can hire a plumber or window installer to connect the well to a drainage system. This can also be a DIY project using a shovel or auger.

Some sump pumps are powered by water rather than electricity. Water-powered sump pumps generally use one gallon of city water to pump out two gallons of water from its basin. Therefore, if you're looking at a potential 10,000-gallon flood, your sump pump will need to use 5,000 gallons of city water to prevent it.

Proper drainage prevents water damage, mold growth, and foundation settling, protecting your home’s structural integrity.
