Question 1

Why Concrete Sinks in Silver Spring, MD

getaligned · Accepted Answer

Silver Spring’s older sidewalks, mature trees, and changing moisture levels often create voids beneath concrete slabs over time. Established neighborhoods, busy road corridors, and properties with shifting drainage patterns frequently experience settlement as the supporting soil moves or washes away. Common causes include:

Loose or poorly compacted soil beneath driveways, walkways, patios, and steps
Clay-influenced soil that expands during wet weather and shrinks during dry periods
Erosion from stormwater runoff washing support material away from beneath slabs
Settlement near utility work, repaired sections, and backfilled areas around older homes

If you leave these problems alone, the slab often sinks further, cracks more, and creates larger elevation differences.

Question 2

Concrete Leveling vs. Replacement: Which Option Is Best?

getaligned · Accepted Answer

Replacing a slab often creates more disruption and expense than homeowners want, especially in areas that see daily use. Concrete leveling, also called slabjacking or concrete lifting, often makes more sense in Silver Spring because it is:

Fast: Many jobs finish in a single day
Cost-effective: Often costs 50–70% less than full replacement
Non-invasive: Avoids demolition and keeps your existing concrete in place
Sustainable: Reuses existing concrete and reduces waste

Many homeowners searching for concrete leveling near Silver Spring are surprised by how quickly we can restore their slab without the mess of 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 examine the slab, surrounding conditions, and underlying voids to choose the best repair approach
Drill: We drill small, carefully placed holes into the concrete
Pump: We inject polyurethane foam beneath the slab to fill voids and raise the surface
Seal: We patch the holes, and the slab is typically ready for use within hours

This process stabilizes the slab from below and restores a safer, more even 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, so we can lift and stabilize the slab fast.

Question 5

When can I use my concrete after leveling?

getaligned · Accepted Answer

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

Question 6

Is leveling better than replacing concrete?

getaligned · Accepted Answer

In many cases, yes. Leveling works faster, costs less, and avoids the mess of demolition and repouring.

Question 7

Will my concrete look brand new?

getaligned · Accepted Answer

Leveling restores function and safety, but it does not remove existing cracks or stains. Many homeowners improve the appearance afterward with pressure washing, sealing, or resurfacing.
