CRACK INJECTION

Concrete Can Crack From Various Causes

Concrete Crack Concrete floors and concrete wall applications can crack from time to time but more then often the crack are only minor and can be repaired in the method of crack injection equipment and materials. The most common causes of concrete cracks are due to such causes as; concrete drying/ shrinking, thermal movement, bad workmanship, using poor quality cement, water leaks and still water build up. The good news for home owners is minor concrete cracks can be repaired without the high costs of hiring a professional but its imperative to investigate and evaluate  what the real cause and fix that problem first. If unsure always consult with a professional.

Three Common Types Of Concrete Damages

The three most common types of concrete damages are; concrete cracks, surface cracks and structural cracks. With each type of damage tends to require certain treatment in repairing effectively and permanently. For structural repairs, it’s a wise choice not to attempt to repair structural damage yourself, rather hire a professional.  As for minor concrete cracks and surface cracks, they can be repaired by home owners in the method of using crack injection repair kits and caulking kits.

DIY Crack Injection Repair Kits

DIY Crack Injection Repair KitsCrack injection repair kits are a good option in filling in cracks for internal and external concrete wall and floor applications. The two most common types of materials that crack injection kits are formulated from are polyurethane or epoxy materials, some kits have the combination of both types of injecting materials pending on the nature of the repair requirements. Always consult with the hardware store representative or the manufacturer in which is the best crack injection repair kit that would be more suitable for specific concrete damages.

Expanding Polyurethane Injection Kits

For small cracks and hairline concrete fractures, injecting expanding polyurethane is often recommended to repair minor cracks of up to half an inch deep and wide. Expanding polyurethane is a foaming material and when it is injected into the crack it will penetrate through the surface crack then the formula expands by up to 20 times of its volume content and completely fills the crack naturally. This injection method if properly implemented ensures water will never penetrate through the cracks again.

Epoxy Crack Injection Kits

Epoxy Crack Injection KitsThe epoxy crack injection formula is another repair option for internal/ external small concrete wall and floor cracks. With the epoxy crack injection formula, it not only stops water from penetrating through the cracks once repaired it also has structural advantages.  Epoxy injection provides structural strength due to the bonding of the concrete and epoxy material combination rather then just concrete, therefore the two materials create a superior bonding agent makes them stronger. Just be aware if the main structural damage is not initially resolved, this repair option is basically a waste of time and money. That’s why it’s so important; to always seek advice before attempting to repair concrete yourself.

Surface Sealer For Crack Injection

Most standard types of epoxy crack injection repair kits contain two parts, one jar is the epoxy content and the other is a surface sealer product.  Surface sealers as part of an epoxy crack injection repair kit is an important formula which is applied after the cracks have been filled which provide short and long term protection. 

Cementous Based Crack Injection

Cementous Based Crack InjectionA cementous crack injection is one of the more versatile repair methods for medium to large concrete cracks and structural damages. The mixing   content is mainly made up of high ratio of portland cement along with other small ratios of certain mixing materials and bonding agents that are poured into injection equipments. This method of crack injection is more often used by professionals for concrete walls and floors that are severely cracked or have structural damage.
