Question 1

Why Concrete Sinks in Prince George’s County, MD

getaligned · Accepted Answer

Prince George’s County has a mix of soil types, established neighborhoods, and stormwater runoff patterns that can gradually create voids beneath concrete slabs. Areas with mature trees, older concrete, and frequent water movement often develop settlement as the supporting soil shifts or washes away. Common causes include:

Loose or poorly compacted soil beneath driveways, walkways, patios, and garage slabs
Clay-influenced soil that expands during wet weather and contracts during dry spells
Erosion from heavy rainfall and runoff washes base material away
Settlement near utility trenches, repaired sections, and backfilled areas around older homes

When you leave these issues untreated, the slab often continues to crack, sink, and collect water.

Question 2

Concrete Leveling vs. Replacement: What’s the Best Choice?

getaligned · Accepted Answer

Replacing concrete often requires demolition, hauling debris, and waiting through a full cure period. Concrete leveling, also called slabjacking, usually makes more sense because it is:

Time-Saving: Many jobs finish in a single day
Cost-effective: Often costs 50–70% less than replacement
Non-disruptive: Avoids tearing out the existing slab or disturbing nearby surfaces
Eco-friendly: Reuses your existing concrete and reduces waste

Many homeowners are surprised by how quickly we can restore settled concrete without the disruption of full replacement.

Question 3

Our Concrete Leveling Process

getaligned · Accepted Answer

We use a modern polyurethane foam lifting method that provides controlled lift and long-lasting support.

What to Expect:

Inspection: We assess the slab and surrounding conditions to determine the right repair method
Drill: We drill small, carefully placed holes in the concrete
Pump: We inject polyurethane foam beneath the slab to fill voids and raise the concrete
Seal: We patch the holes, and the slab is usually ready for use within hours

This process stabilizes the slab from below and restores a safer, more level surface.

Question 4

How long does concrete leveling take?

getaligned · Accepted Answer

Most projects take only a few hours. The foam expands and hardens quickly, which allows us to lift and support the slab fast.

Question 5

When can I use my concrete after leveling?

getaligned · Accepted Answer

You can usually walk on the concrete almost immediately. We often clear driveways and garage floors for vehicles later the same day.

Question 6

Is leveling better than replacing concrete?

getaligned · Accepted Answer

In many cases, yes. Leveling works faster, creates less mess, and costs much less than full replacement.

Question 7

Will my concrete look brand new?

getaligned · Accepted Answer

Leveling restores safety and function, but it does not remove cracks or stains already in the slab. Many homeowners improve the appearance later with washing, sealing, or resurfacing.
