WHAT TO LOOK FOR

Red Flags

Warning signs in your concrete and brick, what they mean, and what happens if they are left.

Each page shows what the problem looks like, what causes it, and what the repair involves. For what to check from fall to spring, see the freeze-thaw checklist.

Parking Garages Plant and Warehouse Floors Balconies Facades and Brick Sidewalks

Parking Garages

AI-generated example image: the concrete ceiling of a parking garage with a long crack, brown and orange rust stains spreading out from it, and a line of white crust along part of the crack.

Rust Stains on a Garage Ceiling

A crack in a garage ceiling with brown or orange staining around it usually means the steel inside the concrete is rusting. What causes it and why the early repair is the smaller one.

What it means

AI-generated example image: the concrete ceiling of a parking garage where a patch of concrete has broken away, leaving a shallow hole with rusted steel bars showing and a ring of rust stain around it.

Concrete Broken Off with Bare Steel Showing

When rusting steel pushes a piece of a garage deck loose, it leaves a shallow hole with the steel bars showing. How to check the concrete around it and what the repair involves.

What it means

AI-generated example image: a parking garage deck where the rubber seal in an expansion joint has torn and sagged into the gap, with salt stains and grit packed into the opening.

A Torn Expansion Joint

The rubber seal in a garage deck's expansion joint keeps water out of the structure. How to spot a torn seal, what it leads to, and why resealing early is the smaller job.

What it means

AI-generated example image: the underside of a concrete parking garage deck. A long crack runs across the ceiling, lined with a white crust, with small white mineral icicles hanging from it.

White Crust and Small Icicles on a Garage Ceiling

White crust and small white icicles along a garage ceiling crack mean water is passing all the way through the slab. What it means and why the repair works from the top.

What it means

Plant and Warehouse Floors

AI-generated example image: a warehouse floor where the gray coating has worn through to bare concrete along curved forklift lanes, with tire marks and coating peeling up at the edges.

A Floor Coating Worn Through in the Forklift Lanes

The turns at aisle ends and the lanes into the dock doors wear through a warehouse floor coating first. What bare or peeling coating means and what the repair involves.

What it means

AI-generated example image: a warehouse floor where a control joint crosses the aisle and the concrete edges along it have chipped and crumbled, with loose pieces in the gap and forklift tire marks across it.

Crumbling Joint Edges on a Plant Floor

When the filler in a plant floor joint wears out, forklift wheels break the edges down. How to spot it, why it spreads, and why the repair is smaller done early.

What it means

Balconies

AI-generated example image: the corner of a concrete balcony slab. The black steel railing post is rusted and flaking at its base, cracks run out from the post, a piece of the slab corner has broken off, and rust stains run down the slab edge.

Rust and Cracked Concrete at a Balcony Railing Post

Water that sits at the base of a steel railing post rusts it below the surface until the concrete around it cracks. What to check on every post, and when to keep people off a balcony.

What it means

Facades and Brick

AI-generated example image: a red brick wall with a window. The steel angle over the window is rusted, rust runs down beside the frame, and a stair-step crack climbs through the mortar from the corner of the window.

A Stepped Crack and a Rust Stain Above a Window

A stair-step crack in the brick and rust running down from the top of a window usually mean the steel lintel over the opening is rusting. What it means and what the fix involves.

What it means

AI-generated example image: a red brick wall where the mortar between the bricks has worn back and crumbled into sand, with open gaps between some bricks and sand on the stone ledge below.

Mortar Joints Worn Back from the Face of the Brick

Recessed, sandy mortar joints let water into a brick wall. A simple key test, where to look, and why tuckpointing early beats rebuilding a section of wall.

What it means

Sidewalks

AI-generated example image: a concrete sidewalk where one slab has lifted at a joint, leaving a raised lip with a chipped edge and a crack across the corner.

A Sidewalk Slab That Has Lifted

Freeze and thaw can push one sidewalk slab up and leave a trip edge at the joint. What to look for, and when grinding or replacing the section fixes it.
