Understanding Structural Cracks

Cracks that form due to foundation movement (i.e. settlement, soil pressure or freeze/thaw cycles) may compromise the basement wall if left unaddressed over time. These cracks, known as structural cracks, usually begin as hairline thin and typically become wider over time. They are more likely to be diagonal, horizontal, jagged or stair-stepped.

The included epoxy with this kit, Emecole Metro 121 Premium Fast Curing Epoxy, begins to thicken within 15 to 20 minutes upon injection into the crack, minimizing the amount of material that can leak out into the soil, reducing wasted material. The added strength of epoxy fuses the cracks back together, resulting in a repair stronger than the original concrete. Cracks are completely filled, keeping out water and soil gases, including radon.

Repairing Non-Structural Cracks?

More times than not, most basement wall cracks are non-structural. They  develop due to initial settling of the foundation or natural shrinkage of the concrete within a few months after being poured. They are usually thin, anywhere from hairline to 1/8″ wide, and are likely to be vertical.

Since these cracks do not pose any structural risk to the foundation, we recommend polyurethane as opposed to epoxy. While epoxy can be used for non-structural cracks, the added expansion of polyurethane makes it the more user-friendly of the two when it comes to injecting. For repairing these non-structural type of cracks,  we recommend the Emecole Metro 10 ft. Foundation Crack Repair Polyurethane Injection Kit.

Repair Cracks from the Inside – No Digging or Drilling

The low pressure 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

Do universal cartridges still contain Part A and a Part B materials?

Yes, the injection material packaged in universal cartridges for this kit contains both Part A and Part B materials. Our universal cartridge is engineered to separate the two component materials horizontally, ensuring they are not mixed while inside the cartridge.

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 surface seal, otherwise, the injected polyurethane or epoxy 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 this can become more complicated. For such situations, we advise you get in touch with an Emecole Metro technical support expert for additional ideas or workarounds.

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. The only caveat is that chemicals should not be stored in freezing temperatures.
