Noticing Cracks in Your Basement Floor? Tips for Northeast New England Homeowners
Have you looked at your concrete basement floor lately? Do you see cracks that resemble spiderwebs or appear as though they may open up into another realm?
You may be worried about cracks in your basement floor — and for good reason. While some cracks result from normal settling and wear and tear, others may point to a serious structural problem you need to address before things get even worse.
Whatever the cause of these cracks in your Northeast New England home, you can do something about them. Here are some tips if you notice cracks in your concrete basement floor.
Are All Basement Floor Cracks Bad?
Not every crack in a basement floor is cause for concern. Smaller cracks — or “hairline” cracks — are usually harmless, typically resulting from general wear or shrinkage when concrete dries. You don’t really need to contact a concrete repair specialist in this scenario, but it’s a good idea to monitor the cracks in case they get bigger over time.
You should take action if you have larger cracks, especially any that measure more than 1/4 of an inch. These may suggest that something’s off with your foundation, so contact a professional sooner rather than later. The right expert will assess the situation and give you options for what to do next. Also get help if cracks accompany other damage, such as basement wall cracks or bowing basement walls.
What Causes Cracks in the Basement Floor?
Basement floors crack develop over time for many reasons, including:
- Foundation Heave: A heaving foundation happens when water under your concrete floor slabs builds up and exerts upward pressure, resulting in ugly cracks in your basement floor.
- Poor Drainage: Improper yard grading and poor drainage, including damaged gutters and downspouts, around your foundation can make heaving worse.
- Freeze-thaw Cycles: Water in the ground surrounding your home can freeze, expand, and then thaw — a process known as a freeze-thaw cycle. This movement might cause cracks in your basement floor.
- Soil Settlement: When the soil under concrete slabs shifts or settles unevenly, foundation settlement results, soon followed by basement floor cracks.
- Heavy Loads: Placing heavy items on your basement floor, such as water heaters and even workout equipment, may lead to cracking.
Living in Northeast New England could make some of these problems worse. For instance, heavy rainfall and snowmelt in our region saturate the ground around your foundation, increasing the likelihood of heave and hydrostatic pressure. Freeze-thaw cycles are also common here during the winter and spring.
How to Fix Basement Floor Cracks
There are different ways to repair cracks in a concrete basement floor.
Many DIY enthusiasts try sealants from the hardware store to fill minor cracks. While this covers cosmetic issues, it’s not a lasting solution for truly problematic cracks. It’s best to leave foundation repairs to the experts if you’re dealing with larger structural cracks.
After a thorough inspection from a professional like Groundworks, you’ll have various options depending on the type of damage and its source. These include:
Targeted Repair Methods
Foundation Piers
If the floor cracks are the result of foundation settlement, different foundation piers provide a lasting solution for foundation stabilization.
- Helical Piers: Best suited for lighter structures, these screw-like piers can help elevate the foundation and guard against future cracking.
- Push Piers: Ideal for heavier homes, these steel piers are driven deep into stable soil layers to support and potentially lift the foundation, reducing the risk of further damage.
- Slab Piers: Specifically designed for homes with slab foundations, these piers reinforce cracked areas, restoring stability and preventing additional issues from developing.
Concrete Lifting
Some areas of cracking concrete can benefit from an innovative repair method. Groundworks’ concrete lifting system consists of polyurethane foam injections that fill cracks, gaps, and voids and potentially level a floor if it’s sinking. Our PolyRenewal™ system stands out from traditional concrete lifting methods like mudjacking because it dries quickly and doesn’t destroy the environment.
Additional Protective Measures
Wall Repair Systems
Basement walls under the same stress often benefit from specialized reinforcement techniques:
- Carbon Fiber Straps: These sleek, high-strength straps are perfect for walls with minor cracking, providing discreet, effective reinforcement.
- Wall Braces: For more pronounced bowing or fractures, wall braces offer internal support by anchoring to structural framing and can be tightened over time for potential correction.
- Wall Anchors: In areas with enough exterior space, wall anchors offer a powerful alternative by permanently stabilizing walls that have shifted more than two inches inward.
Basement Waterproofing Systems
Moisture management with the following solutions is the key to preventing conditions that lead to basement floor cracks:
- Interior Drainage: Iterinor basement drains collect water before it can enter your living space, channeling it to a designated discharge point to keep your foundation dry and protected.
- Sump Pumps: Basement sump pumps remove water collected by the drainage system and expel it safely away from your home.
- Wall Vapor Barriers: Wall vapor barriers seal off basement walls to block moisture intrusion, helping to prevent mold, mildew, and structural damage caused by excess dampness.
- Dehumidifiers: Energy-efficient basement dehumidifiers regulate humidity levels and improve air quality by reducing moisture and discouraging mold, wood rot, and pests.
As you can see, basement floor cracks can be complex and accompany other problems. Working with trusted pros like Groundworks gives you peace of mind that comes with lasting solutions tailored to meet your home’s unique needs.
