Determining the right type of concrete repairs for your commercial property in Edmonton is not always easy. Especially if it is your first time dealing with this common property issue. There are different options for concrete repairs available that each involves a distinct set of benefits and shortcomings. Understanding the differences between methods for repair can help you narrow down your options and choose the solution that will provide long-term benefits, while minimizing any negative impact on your short-term operations.
PROS, CONS, AND DIFFERENCES BETWEEN EPOXY AND POLYURETHANE CONCRETE CRACK INJECTIONS
Two popular options are available for crack injection repairs for your foundation: epoxy injections and polyurethane foam injections. Use the guidelines below to determine which method is right for your commercial property in Edmonton and contact Osco Mudjacking & Construction for expert advice:
- Similarities – Both epoxy and polyurethane are resins that are created by mixing two components. For epoxy, this includes epoxy and a hardener, and for polyurethane it typically includes polyurethane and an activator or accelerator. The thickness of the material will be impacted by the exact formulation.
- Differences – Polyurethane has a much wider variety in terms of components and therefore in terms of texture. Rubbery, powdery, and rigid variations are all possible depending on the mix. Epoxy is more plastic in texture and forms a hard bond once cured. Polyurethane injections can take anywhere between 15 to 45 minutes to cure, whereas epoxy options need 3 to 4 hours to fully cure at room temperature.
- Advantages – The major benefit of epoxy is its strength. Once cured, the tensile strength far exceeds that of the surrounding concrete foundation. Regardless of thermal tension or pressure from soil or other factors, the epoxy is reliable. This method has a very low failure rate, providing technicians with visual indicators of success, and can be suitable for very small and fine cracks. Polyurethane is less dependent on the condition of the crack and other weather variables, giving it more applications in moist, muddy, or otherwise unfavourable conditions. High injection pressure can be used with this material and voids are effectively filled since the polyurethane expands. Another major benefit is the quick cure times and fact that success can be confirmed both visually and by using tests that ensure leaks are fully sealed.
- Disadvantages – Epoxy concrete repair injections can be difficult to use on a previously repaired crack or failed DIY attempt. This material may not perform well in environments where moisture is present. The epoxy curing time can be a benefit but may also cause issues if compacted soil, air gaps or other issues are present. Once cured, the lack of flexibility may be considered a shortcoming. Polyurethane comes with its own disadvantages. Unless it is properly reinforced by your concrete repair company, it can tear under tension.
