ᐅ 2K Injection Mortar Used for Other Purposes – Heat Generation?

S-d1985Hello everyone,
I have a question regarding 2-component injection mortar.
Here is a somewhat unusual situation:
I live in an old building (really old: half-timbered house built in 1550). It was properly renovated a few years ago, but of course, a building like this can’t be completely mouse-proof.
Unfortunately, mice have now appeared in the kitchen, and the path was quickly identified – the utility pipes (water, electrical, heating, wastewater) going into the crawl space were not properly sealed.
These pipes are hidden behind the kitchen cabinets; the only way to reach them without tearing out the kitchen was to push steel wool into the cavities with a long rod and then seal it carefully and in a way that would resist mouse bites as much as possible. This was only possible with a cartridge gun because otherwise I couldn’t have reached it.
Therefore, I used 2-component injection mortar since it hardens very solidly. So far, everything went well, but afterwards I became concerned about the heat generated during curing.
I understand that the mortar is actually intended for anchoring threaded rods in masonry, not for surface sealing. After using nearly 2 cartridges to seal the area, I’m now wondering whether the heat generated around the plastic wastewater pipe could have caused issues. The resin cures with heat generation.
I didn’t apply it very thickly but about 1-2 cm (0.4-0.8 inches) in a fairly broad area.
Do you think this could be problematic? I haven’t noticed any burning smells or anything similar.
Unfortunately, I couldn’t find any information about heat generation in online research or in the product’s safety data sheet (tox liquix Multi 1 from Hornbach).

wiltshire21 Dec 2025 15:47I have no idea at exactly what temperature the curing takes place, and I am not an expert in the broad field of cement. However, the physics of hydration, which is involved in the hardening of cement, is well understood. Physically, the maximum achievable temperature is limited by the boiling point of water. Therefore, exceeding 100°C (212°F) under normal pressure conditions is not possible. If you understand this, you can rest easy.
