Driveways, foundation walls, and flaking, chipping, and breaking apart in chunks are the most common issues a homeowner faces, known as spalling concrete. Due to weather changes, it's a common issue all across Brooklyn brownstones, but if you inspect early, you can save on structural repair costs.

With a professional who has years of experience, you get a trusted repair, installation, and inspection solution. In this blog, you explore the reasons behind spalling concrete and how professional concrete contractors Brooklyn save your residential property.​

What Is Spalling Concrete?

Spalling occurs when a layer of the concrete surface flakes, peels, or pops off, leaving a rougher material (and sometimes the rebar) underneath. It happens on sidewalks, steps, stoops, parging, foundation walls, and retaining walls, and it affects your property value. At first it looks like minor pitting, but with time it increases, weakening the overall structure.

The Main Causes of Spalling in Brooklyn Homes

Freeze-Thaw Cycles

Brooklyn winters have more freeze-and-thaw cycles. Concrete cracks can have small openings where water can enter and freeze, causing the water to expand and exert pressure on the concrete. Repeat this many times, and the surface cracks and pops off. It will cause spalling on older Brooklyn concrete stoops and steps.

Poor Mix Installation

A mix that has been poured with too much water or was not finished and cured to the proper standards will be much more porous, and therefore susceptible to moisture damage. A frequent problem with sidewalks or side stoops in older row houses is that they were poured many years ago to the standards of the day.

Rebar Corrosion

Many Brooklyn homes feature concrete stoops and stairs which are reinforced with steel rebar. If water enters the concrete and comes into contact with this steel, it produces rust. Rust grows, and this growth is what causes the concrete to crack. This is one reason it sometimes appears worse than it is, because the damage occurs beneath the surface.

De-Icing Salts

Rock salt is used to keep your steps and sidewalk safe throughout the winter, but it has a downside: it helps to accelerate spalling. The use of salt reduces the freezing point of water, increasing the number of freeze-thaw cycles, and some de-icing chemicals can cause concrete to break down over time.

Poor Drainage

When water accumulates around your foundation, stoop, or masonry work but cannot drain away, it is a red flag. Every other cause listed here is exacerbated by the continual exposure to moisture, whether from freeze-thaw or rebar corrosion.

Why This Matters More in Brooklyn

With the age of its stock, the coastal climate, and the reliable change of weather that comes with the winter months, Brooklyn properties are spalling at a rate that is greater than the rest of the country. Many times the original concrete and masonry work on brownstones, limestone-front homes, and rowhouses is 70, 80, even 100+ years old. This can take a lot of time for water infiltration and freeze-thaw to cause damage, even though it's not yet evident.

What Homeowners Should Do

Spalling is not self-correcting, and minute chips that go unaddressed will propagate. If you see flaking concrete, exposed aggregate, or rust stains on a stoop, wall, or walkway, consider having it inspected before winter. When left untreated, small surface spalling can develop into structural cracking, which is much more costly to repair. 

That's where the expertise of trusted concrete contractors Brooklyn really counts. A competent team can determine the extent of the problem, whether it is just a resurfacing issue or a structural problem requiring rebar replacement.
