Stem wall spalling repair methods and costs

Do you have concerns that spalling will cause the structural integrity of your foundation to be compromised? Do you have the acne-like pockmarks that are characteristic of spalling spread across the wall of your stem? This article is for you if you are interested in learning about the most common method of spalling repair as well as the average cost associated with it.

What exactly is spalling, and why does it represent a risk to the foundation of my building?
The process of spalling involves the fragmentation of hard materials such as concrete, rock, stone, and ore into more minute pieces (generally by an unmitigated water source). To be more specific, concrete spalling is the process by which concrete is broken down as a result of natural weathering and/or chemical reactions, which frequently results in concrete that is fractured and compromised. In a nutshell, spalling is a sign that there has been significant water damage.

The concrete stem walls and footings can be weakened by spalling, which ultimately threatens the foundation’s capacity to support its own structural weight. Believe it or not, this is because concrete has a porous structure, much like a sponge.

Water seeps into the cement sponge that makes up your foundation because of improper drainage and water leaks, which causes the cement to spall. Because spalling makes it possible for more water to penetrate even further into your foundation, a vicious cycle begins to take place.

When water comes into contact with the rebar that is used to reinforce the foundation, the steel begins to rust and expand. This causes the steel to exert an incredible amount of pressure, which fractures the stem walls and can break off entire chunks of concrete. Oxide jacking or rust burst are both terms that are used to describe this phenomenon.

Rust can cause an expansion of the rebar that is up to seven times its original thickness and can lead to a pressure of nine thousand pounds per square inch. Cracking and disintegration of the support system can occur as a result of oxide jacking, which can be harmful to your foundation.

The purpose of a foundation is to ensure that the weight of the house is supported and distributed evenly throughout the structure. Cracking and the subsequent damage caused by water put this function in jeopardy.

In a nutshell, spalling is not a problem with foundation settlement (where the foundation sinks into incompetent, non-load-bearing soil), but rather a problem with water intrusion that is made worse by rusted internal rebar.

Carbon Fiber Wraps for the Repair of Spalling

Carbon fiber wraps, which are extremely durable yet flexible sheets of an interwoven material similar to Kevlar, are used to repair stem wall spalling. These wraps offer both structural and waterproofing support for the stem. Repairing damage caused by spalling or water provides additional structural reinforcement in addition to preventing further damage from occurring.

In addition, carbon fiber wraps are a well-liked repair option for bowing basement walls, cracked footings/stem walls, and caissons that need to be spall-proofed. The most common type of adhesive utilized in carbon fiber repair systems is epoxy, which is a powerful industrial glue and sealant.

Cost of Repairing Spalling Damage with Carbon Fiber Wraps
Repairing spalled or cracked footing or stem walls with carbon fiber wrap is a wonderful option because it is more cost effective than removing and replacing an entire section of the footing or wall. The cost of repair for carbon fiber wrap is approximately $5,000 on average.
