Patio leveling and void filling
Patios settle at the corners and edges, and water can tunnel out the soil underneath until the slab is bridging over empty space. We fill the voids with foam, lift the patio back to level, and get water draining away from the house again.

Why patios sink
Most patios are poured right off the back of the house, over soil that was disturbed during construction. Gutters and downspouts dump water at the edges, and over time the soil underneath washes out or compacts.
Foam does two jobs here: it fills the hollow spaces that make a patio crack, and it lifts the slab to restore the slope away from the house. It’s a fraction of the cost of breaking out and re-pouring a patio.
Before and after
What customers say
“I thought I was going to have to tear a $16,000 wall and concrete patio apart to redo it but they fixed it for just under 3k… it looks great! I’m very excited because the world is expensive but this saved me a lot of money!”
“There were massive hollow voids beneath the concrete slab… the foam completely filled the empty space, sealing the entire edge right against the rocks and locking the patio down.”
“Slab Science corrected a recently poorly poured patio slab in my backyard. They raised an overly sloped area to a very acceptable recreational level. Professional from the first phone call to the final text. Careful and meticulous.”
Patios FAQ
Can you fix a patio that was poured with the wrong slope?
Often, yes. We can raise the low side of a slab to improve how it drains. We’ll tell you what’s possible during the assessment.
What if there are hollow spots under the patio?
That’s exactly what foam is good at. It fills the voids first, then lifts.
Is it cheaper than a new patio?
In almost every case. You keep your existing concrete, with no demolition and no new pour.
