How does Polyurethane foam concrete raising work?
Great question! Firstly, we believe it’s good for you to know that most concrete raising jobs will take between one to two (1-2) hours – start to finish – and your concrete will be ready for use immediately upon completion!
1. When you level your uneven concrete using poly foam concrete raising techniques, ⅝” injection holes (Size of a dime!) are strategically drilled around the areas where the concrete is sunken and requires lifting.
2. The concrete raising equipment is contained in a truck or trailer and has a sufficient length of hose to accommodate most locations, the hose is extended to reach the area in need of repair.
3. Once everything is prepped and the hose and materials are in place, the polyurethane foam is injected through the holes which fill the space underneath the concrete slab, using the concrete slab itself to drive the foam into the crevices, thereby lifting the concrete back to its original, correct level.
4. Upon completion of leveling the concrete, the injection hole(s) are filled discretely with new cement, allowing you to use your surface immediately.
It’s as simple as drill, pump, and patch! Your concrete is ready to use immediately!
In Pennsylvania especially, it’s no secret that cold, wet winters can wreak havoc on your concrete. With the ongoing expansion and contraction caused by the changing weather, the ground below your driveway, sidewalks, and surrounding your foundation will—over time—begin to shift. If you have a concrete slab in your driveway, sidewalk or basement which is uneven, or even cracking, replacement of that slab is not your only option.
What types of problems can concrete raising fix?
Concrete raising is a fantastic alternative to replacing your concrete, often timessaving you over 50% of the cost of replacement! Some common areas we raise, level and repair concrete slabs are patios, front porches, driveways, sidewalks, garage & parking slabs, steps, and pool decks.
Did you know?
Steps should be 7 3/4 inch high? Anything other than that can be a tripping hazard. Get your stoop raised right, with Northeast Foundation & Concrete, Inc.!
Concrete raising in Pennsylvania is the first option you should explore when considering fixing your uneven concrete slabs. There are two main types of concrete raising solutions available-polyurethane foam concrete raising and mudjacking concrete raising.
We use polyurethane to level concrete. It’s faster, cleaner and lasts longer than traditional mud-jacking. If your sidewalk, driveway, garage floor, curb or pool deck has settled, bellied or heaved contact us today for a free estimate.
Benefits of raising concrete with polyurethane foam:
1. Polyurethane foam concrete raising is more cost-effective than replacing your concrete slabs
2. Raising concrete with polyfoam typically takes a couple of hours and is ready immediately upon completion (as compared to hours or days)
3. Northeast Foundation & Concrete is the premier concrete raising company in Pennsylvania! We are experts in polyurethane concrete raising services, and have been recommended by satisfied customers all over the Commonwealth!
What causes concrete to settle?
- Poor or improper compaction of the base before concrete was poured: The weight of the slab will further compact the base after curing, and settlement can happen quickly.
- Climate: The Polar Vortex, experienced last year by many in the northern hemisphere, wasn’t just hard on you, but also on your concrete. Freezing and thawing causes slabs to expand when frost is in the ground – it causes concrete to heave or raise. When the ground thaws, the concrete will settle again, but many times not to where it was originally. This results in trip spots between shifting slabs. On the opposite end of the climate spectrum, heat and drought can cause expansive clay soils to shrink, causing the slabs to settle. When the clay soils receive rain and expand once again, the concrete slabs shift and become uneven.
- Erosion: Damaged water and sewer lines, improperly placed downspouts and excessive rain can all lead to a washout of base materials under concrete causing the slabs to settle.
- Machine/Traffic Vibrations: Concrete slabs may shift or settle on highways or in industrial settings where there is frequent heavy vibrations or loads being transported. The vibrations from machinery and passing traffic can lead to the base compacting and slabs settling or moving.
- Slab Curl/Rocking Slabs: Slab curl occurs when a relatively large section of concrete is poured. During the curing process, the top slab may cure slightly faster causing the slab to curl, rock, and become unstable. Vibration can also cause slabs to settle.
