[vc_row][vc_column][vc_column_text]Why <\/em>rebar corrosion is costing us more than we realize\u2014and how GFRP\u00a0rebar\u00a0changes the equation.<\/em><\/p>\n

Concrete may be the most widely used construction material in the world\u2014but without the right reinforcement, it\u2019s vulnerable to a costly and dangerous enemy: corrosion.<\/p>\n

For decades, steel rebar has been the standard. But steel\u00a0rusts, and when it corrodes, it expands, causing the surrounding concrete to crack, spall, and ultimately\u00a0fail.\u00a0<\/strong><\/p>\n

Across the United States and beyond, the result is billions in\u00a0repair costs, shortened service life, and, in many cases, compromised safety.<\/p>\n

According to a report by\u00a0NACE\u00a0International<\/a>, the direct cost of corrosion in the United States is $276 billion\u00a0per year ($1,400 per person per year) \u2013 approximately 3.1% of the nation\u2019s Gross Domestic Product (GDP).<\/p>\n

This is more than a materials issue. It\u2019s an infrastructure crisis.<\/p>\n

Corrosion of Rebar in Concrete: A Silent, Systemic Problem<\/strong><\/h3>\n

Once corrosion begins, it\u2019s only a matter of time before the structural integrity of the concrete is affected. Chlorides from de-icing salts, coastal exposure, and even humidity can penetrate concrete and reach embedded steel, triggering rust.<\/p>\n

The effects?<\/strong><\/p>\n

\u2713\u00a0Loss of bond between steel and concrete<\/p>\n

\u2713\u00a0Expansion that causes cracking and delamination<\/p>\n

\u2713\u00a0Accelerated degradation in high-chloride and moisture-prone environments<\/p>\n

\u2713\u00a0Increased inspection, repair, and lifecycle maintenance costs<\/p>\n

From parking garages and bridge decks to tunnels, seawalls, and water treatment facilities, corrosion is the common denominator behind premature failure.<\/strong><\/p>\n

Also included in this family of failing structures are driveways, patios, pools and other residential and light commercial applications.<\/p>\n

What If Concrete Reinforcement Didn\u2019t Corrode?<\/strong><\/h3>\n

That\u2019s where GFRP (Glass Fiber Reinforced Polymer), comes in. Unlike steel, fiberglass rebar does not corrode.<\/p>\n

It resists moisture, chemicals, chlorides, and electrochemical reactions\u2014making it a true long-term solution for concrete durability.<\/p>\n
