EPOXY CRACK INJECTION

TOPCOR Services, Inc. is one of the premier specialty contractors that has extensive experience with Epoxy Crack Injection processes and techniques.  Epoxy Crack Injection is frequently utilized to structurally bond cracks in concrete.  In order for Epoxy Crack Injection to be successful, the cause of the crack should be determined if they are working cracks and to what extent they are opening and closing due to changes within a day’s conditions.  Typically, changes in temperature and moisture content will cause this movement.  Concrete movements can be restrained by bonding with Epoxy Crack Injection if the strength of concrete is greater than the resulting bond between the epoxy compound and the concrete being injected.  If the concrete is moving greater than the bond between the epoxy compound and the concrete, generally a crack will develop parallel to the crack injected, therefore, if the crack is knowingly moving more than the process can handle, you must first remedy the condition causing this movement in order to have a successful injection.

EXECUTION OF EPOXY CRACK INJECTION: A typical process for Epoxy Crack Injection includes the following:             Surface Preparation             Porting             Surface Sealing            Epoxy Injection            Finishing TOPCOR offers services for sealing, porting, and injecting cracks including design, material selection, and application methods.

MATERIALS:

A variety of materials from different manufacturers are available depending on the application.  Generally, Epoxy Injection Resins are two-component and vary in viscosity.  It is important to understand that Epoxy Crack Injection resins should be moisture tolerant and 100% solids since concrete substrates nearly always have moisture vapor present.  Other properties to consider when selecting an Epoxy Crack Injection resin are user-friendly ratio, strength, workability and working life.

METHODS OF PORTING:

Due to TOPCOR’s experience with Epoxy Crack Injection, we have become expert at identifying appropriate porting methods.  We take into account aspects such as location of ports, spacing, site selection and injection strategy.  Some of our typical porting methods include:

Surface Mounted Ports     
Drilled In Ports or Socket type
Interruption in Seal or Impingement

METHODS OF SEALING:

Packing – Stuffing the epoxy sealer directly into a surface crack.
Routing – Routing is performed using crack chasing diamond blades and filled with epoxy sealer material.
Capping – A Cap Seal is sealer that is installed over the surface of a crack such that it bridges the cap.

INJECTION: The Epoxy Crack Injection process involves determining the proper injection pressures, injection durations, as well as the order in which to inject ports.  With TOPCOR’s experience, we evaluate each crack to determine the best process.  This injection process is often over-simplified in the industry.  TOPCOR uses its experience to develop an injection process that will accommodate a variety of factors with cracks such as dimensions and orientation or crack layout. EQUIPMENT: Crack injection is performed using metering, mixing and dispensing pressure injection equipment, which can be used for either low or high-pressure injection applications. FIELD QUALITY CONTROL: Quality control of Epoxy Crack Injection is imperative in order to have a successful injection.  TOPCOR has a quality control system in place that insures clients receive a proper Epoxy Crack Injection job, which includes: Ratio Testing Pressure Testing Core Test/Appraisal QC Record Keeping
