Emecole Metro 30 ft. DIY Foundation Crack Repair Epoxy Injection Kit

Repair basement wall cracks in need of structural strength. Using the proven crack injection process, this fully equipped kit includes the components needed to repair approximately 30 feet of cracks up to a 1/4″ wide in poured concrete. No special skills are required – simply follow the step-by-step instructions (refer to the written and video instructions further below).

This kit features Emecole Metro 121 Premium Fast Curing Epoxy, our most advanced epoxy that we have been manufacturing and supplying for over 30 years. Upon injection, Emecole Metro 121 Premium fuses cracks together, making repairs stronger than the original concrete. By filling the depth of the crack, this also provides a waterproofing solution that stops cracks from leaking water.

The development of structural cracks form as a result of movement (i.e. settlement, soil pressure, freeze/thaw cycles) against the foundation, which causes stress. The resulting cracks are usually diagonal, horizontal, jagged, or stair-stepped. In addition to allowing in water, these cracks may widen over time, which may eventually compromise the structural integrity of the foundation. For cracks that do not pose a structural risk to the foundation, we recommend using our 30 ft. Polyurethane Injection Kit.

The strong bonding characteristics of Emecole Metro 121 Premium makes it the preferred injection option for repairing structural cracks. Its overall strength ensures it won’t deteriorate over time. In addition, cracks are filled from front-to-back and bottom-to-top. The end result is a strong and watertight repair that helps maintain a dry and healthy basement environment.

For foundations where active movement continues to be a reoccurring issue, additional reinforcement may be necessary to prevent the development of additional cracks. For such scenarios, the added use of our Carbon Fiber Power Grids may be used in conjunction with the crack injection process.

Repairing Structural Cracks with Epoxy Injection

When we label a crack as structural, we are identifying cracks that form due to repeated foundation movement, which may occur from settlement, soil pressure or freeze/thaw cycles. Structural cracks can begin as hairline thing and may become wider over time. They tend to be diagonal, horizontal, jagged or stair-stepped. If left unaddressed, these cracks may continue to deteriorate and can potentially put the foundation at risk.

We recommend epoxy injection for repairing structural cracks. The included epoxy with this kit, Emecole Metro 121 Premium Fast Curing Epoxy, has added bonding characteristics that fuses cracks back together, providing a very strong and watertight repair. Once fully cured, a crack injected with Emecole Metro 121 is stronger than the original concrete.

What also separates Emecole Metro 121 from other epoxies is that it begins to rapidly thicken within 15 to 20 minutes after being injected into a crack. By thickening up within minutes as opposed to hours, the amount of epoxy material that can leak out into the soil is minimal, maximizing the opportunity to ensure that the crack is completely filled.

Repairing Non-Structural Cracks?

Thankfully, most cracks that develop on poured basement walls are not structural. A non-structural crack develops from foundation settling or concrete shrinkage (with commonly happens for several months after being poured). These cracks tend to be thin, anywhere from hairline to 1/8″ wide, and are vertical. While such cracks do allow in water and soil gases, such as radon, they do not pose a structural risk to the foundation.

For repairing non-structural cracks, we recommend the Emecole Metro 30 ft. DIY Foundation Crack Repair Polyurethane Injection Kit. The premium polyurethane included with that kit has a high expansion rate, making the injection process more user-friendly, resulting in a completely filled crack that is flexible and watertight.

Frequently Asked Questions

If the basement wall crack is high enough to raise above grade, does the exterior of the crack need to be covered from the outside?

Yes, any cracks that are exposed on the outside because they are above grade will need to be covered with your included Emecole Metro Surface Seal, otherwise, the injected polyurethane will leak out, potentially compromising the repair in addition to also wasting material.

A repair to my basement wall crack was previously attempted with the use of hydraulic cement and has since started to leak water again. Can your product still be used to rectify the previous repair attempt?

Yes. The use of this kit requires access to the crack, so a few extra steps will be necessary. The hydraulic cement should be removed by chipping and grinding in order to gain access to the crack. There are some scenarios where such scenarios is more complicated. For such situations, we advise you get in touch with an Emecole Metro technical support expert for additional ideas.

Can this product be used in the middle of winter or when the temperature outside is below freezing? What is the coldest (or warmest) temperature your product will work in?

The ideal temperature for the use of the materials packaged in this kit is between 40 and 100 degrees Fahrenheit. Assuming that the basement is heated, any outside temperature should not impact the performance of the chemicals during the basement crack repair process.
