Ground support service

Void Filling & Soil Stabilization in Maryland, Virginia & Delaware

Relevel uses dual-component polyurethane foam to fill hidden voids and reinforce weak or eroded soil beneath concrete and load-bearing areas. The expanding material reaches unsupported spaces, builds a stronger base, and helps reduce continued movement. Service is available for residential and light commercial properties throughout Maryland, Virginia, and Delaware.

Signs and causes

When the Visible Slab Is Only the Symptom

Settlement often continues because the support below the concrete has been weakened by erosion, poor compaction, washout, or hidden gaps. Warning signs include recurring sinking, hollow-sounding slabs, soft edges, reopened cracks, pooling water, and movement after previous surface repairs. Relevel evaluates the visible issue and the conditions below before recommending stabilization.

Why this service works

Support the Ground Before the Movement Spreads

Polyurethane void filling targets the unsupported areas that allow concrete and structural surfaces to keep moving.

Fill Hidden Gaps

Expanding foam reaches voids beneath slabs and foundations where dirt, mud, or surface patches cannot provide lasting support.

Reinforce Weak Soil

The injection process compacts loose material and builds a stronger base below the affected area.

Reduce Continued Movement

Address the support problem beneath the surface before settlement, pooling, or cracking becomes more extensive.

How it works

How Relevel Fills Voids and Stabilizes Soil

The team identifies unsupported areas, creates targeted access, and injects foam where the ground needs added support.

Evaluate

We review settlement, erosion, washout, drainage, slab movement, and the likely void locations.

Create Access

Small access points are positioned to reach the weak or unsupported areas below.

Inject & Stabilize

Dual-component polyurethane expands into voids, compacts loose material, and reinforces the base.

Verify & Seal

The support and surface response are reviewed, then the access points are sealed and cleaned.

Service questions

Void Filling & Soil Stabilization FAQs

These answers explain when stabilization is needed, what affects cost, and whether lifting must happen at the same time.

How much does void filling cost?

Pricing depends on the size and depth of the voids, the affected area, access, soil conditions, and the volume of polyurethane required. Relevel provides a project-specific estimate after evaluating the site.

Can voids be filled without lifting the slab?

Yes. Some projects need stabilization and void filling without a visible lift. Other projects require both support and elevation correction. Relevel matches the injection plan to the condition below the surface.

What causes voids beneath concrete?

Common causes include erosion, washout, poor soil compaction, leaking water, drainage problems, and natural settlement. Identifying the cause helps determine whether stabilization, lifting, water redirection, or another repair is appropriate.
