Help Deciding Whether to Inject with Polyurethane or Epoxy

When repairing a basement wall crack via low pressure crack injection, the two choices are polyurethane or epoxy. Which injection material you decide to use largely depends on the type of crack in need of repair. While experienced contractors may use an injection material based on personal preference, we recommend that homeowners or anyone new to repairing basement wall cracks use our recommended guidelines when deciding whether to use polyurethane or epoxy.

Polyurethane is Recommended for Most Cracks

Most inquiries we receive from homeowners describing their specific crack in need of a repair fall in line with the characteristics of a non-structural crack. 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 these non-structural cracks, we recommend injecting with Emecole Metro 102 Premium Polyurethane due to its high expansion rate. Upon injection, Emecole Metro 102 expands up to 20 times its original state of volume, providing the best opportunity at filling the crack. The expansion capability of Emecole Metro 102 makes it the more user friendly option for homeowners, while also making it the less expensive option since it requires less material to fill a crack as opposed to epoxy, which does not expand. Once cured, Emecole Metro 102 forms a flexible and watertight repair.

Structural Cracks Require the Added Strength of Epoxy

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 usually end up being at least 1/8″ wide and tend to be diagonal, horizontal, jagged or stair-stepped. If left unaddressed, these cracks may continue to deteriorate over time and can potentially put the foundation at risk.

For the long-term protection of the foundation, the safe choice for repairing structural cracks is injecting with Emecole Metro 121 Premium Fast Curing Epoxy. The added bonding characteristics of Emecole Metro 121 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.

Since epoxy does not expand, unlike polyurethane, it does require more material to repair the same crack. The positive trade off is that epoxy provides a stronger repair for cracks where foundation movement has been a lingering problem.

Help Deciding Which Surface Seal to Choose

Surface Seal is used to seal basement wall crack surfaces in order to prevent injected Emecole Metro 102 Premium Polyurethane from leaking out the front of the crack. It is also used for the bonding of surface ports to the crack. The Emecole Metro 30 ft. Basement Wall Crack Repair Kit with Polyurethane Injection has two Surface Seal choices:

  • Emecole Metro 901 Slow Curing Surface Seal: Cures in approximately 2 to 4 hours. Homeowners not overly concerned with the appearance of their basement wall will opt for this Surface Seal, as it can stay on the wall afterwards. It may be removed, if desired, by chipping or grinding it off.
  • Emecole Metro 322 Premium Surface Seal-n-Peel: Cures in approximately 15 to 30 minutes and easily peels off the basement wall afterwards, leaving a clean finished look. This is the ideal choice for homeowners who prefer to remove the surface seal once the crack is repaired. Because Emecole Metro 322 Premium Surface Seal-n-Peel easily peels off the basement wall, no chipping or grinding is necessary.

Cracks are Repaired from the Inside – No Digging or Drilling

The low pressure crack injection process for repairing basement wall cracks in poured foundations is completed from the inside. This allows homeowners to inject straight into the crack, while the exterior soil provides a stop-gap to ensure that injected polyurethane stays within the crack, resulting in a completely filled crack.

The included Surface Ports, which adhere to the front of the crack at every six to eight inches, allow for the polyurethane material to be injected straight into the crack. There is no need to drill holes into the wall, helping to save time while reducing unnecessary labor.

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.
