Moisture penetration
Unsealed or worn surfaces absorb water from irrigation, weather, and pool splash. Repeated soaking and drying erodes the surface layer and feeds staining and mildew in shaded spots.
Concrete Repair · Problem Signs · Since 2011
Surface damage is concrete aging faster than it should.
Pits, flaking, and stains mean moisture and wear are getting into the slab. Caught early it is a surface fix. Ignored, it works its way down.
Let's take the first step toward solid ground.
A local specialist will evaluate your foundation, walk you through the findings, and send a clear estimate. No cost, no pressure.
What this symptom means
Pitting, Flaking, or Staining: diagnosed and explained.
Not every concrete problem starts in the soil. Pitting, flaking, and staining are surface stories: the top layer of the slab breaking down under moisture, sun, chemicals, and wear. Pitting shows up as small holes peppering the surface where weak spots in the finish have eroded out. Flaking, which contractors call spalling when it runs deeper, is the top layer delaminating and peeling away, exposing the rough aggregate underneath. Staining ranges from dark moisture and mildew shadows in shaded areas to rust marks and chemical discoloration around pools and driveways. These start as cosmetic complaints, but they do not stay that way, because a worn surface is a porous surface. Once the dense finished top is gone, water soaks into the slab body freely, carrying pool chemicals, fertilizer, and minerals with it, and each cycle of soaking and baking erodes a little more. In the high desert and mountain edges of our service area, winter freeze and thaw cycles accelerate the damage sharply: water in the pores expands as it freezes and pops the surface apart from within. A slab with surface damage and a sound structure is very fixable, and the earlier the surface is repaired and sealed, the cheaper the fix stays.
For the repair side of this, the concrete repair solutions page lists every method Dalinghaus installs, including the ones that fix problems other than pitting, flaking, or staining.
Catch It Early
What to check on the surface
- Water soaking in instead of beading If water darkens the slab and disappears rather than beading up, the surface has no protection left and is absorbing everything that lands on it.
- Gritty or dusty surface A surface that sheds sand and dust underfoot is actively eroding, one footstep at a time.
- Flakes exposing aggregate Peeling that reveals the rocky interior means the finished layer is delaminating and the damage will spread from the exposed edges.
- Deepening or spreading stains Stains that grow or darken show moisture is living in the slab, not just landing on it.
Most Common Causes
What causes pitting, flaking, or staining in regional homes.
Freeze and thaw cycles
In the high desert and mountain areas we serve, water absorbed into the slab expands as it freezes, popping the surface apart from within. A few hard winters can pit an unsealed slab noticeably.
Chemical exposure
Pool chemicals, fertilizers, and harsh cleaners attack the surface paste, etching and discoloring it. Pool decks and planter edges usually show it first.
Weak surface finishing
Concrete that was overworked, overwatered, or poorly cured during the original pour carries a fragile surface layer that wears through years early.

Depth. Pitting is small holes eroding out of the surface finish, while spalling is whole flakes or chunks of the top layer breaking away and exposing the aggregate underneath. Both come from moisture working in the surface, but spalling means the damage has gone further and the repair involves resurfacing rather than spot filling.
