Ponding is standing water that collects on or beside a concrete slab after rain, one of the earliest visible warnings that a slab has settled or lost its drainage pitch.
In depth
Properly placed flatwork is pitched so water runs off and away from structures. When soil settles, that pitch flattens or reverses, and water starts collecting in low spots, on the slab, along joints, or against the foundation.
Ponding is both a symptom and an accelerant. The low spot exists because soil moved. The standing water then soaks through joints and cracks, erodes more soil, deepens the low spot, and in winter becomes an ice patch and freeze-thaw multiplier. Left alone, ponding almost always gets worse.
How Acme applies it. We restore the slab\u2019s original pitch by lifting the settled side, so water sheds the way it was designed to. Combined with joint sealing, this breaks the water, erosion, and settlement cycle rather than just treating the surface symptom.

Frequently asked questions
Is ponding on my driveway really a problem?
Yes. It means the slab has lost pitch, and the water is actively eroding the soil below. It is also tomorrow\u2019s ice patch. Early correction is cheap, and waiting is not.
Can concrete raising fix water pooling near my foundation?
In most cases, yes. Re-pitching the settled slab redirects water away from the foundation, often paired with downspout extensions and joint sealing.
