Dry ice can be used for loosening asphalt floor tiles or car sound deadening material, making them easy to prise off,<ref name=PM169>{{cite journal |date=February 1961 |author1=Horrell, Bill |title=Dry ice pops off Asphalt Tile |journal=Popular Mechanics |volume=115 |issue=2 |page=169 |url=https://books.google.com/books?id=R9wDAAAAMBAJ&pg=PA169 |access-date=2016-09-23 |archive-date=2013-06-06 |archive-url=https://web.archive.org/web/20130606003724/http://books.google.com/books?id=R9wDAAAAMBAJ&pg=PA169 |url-status=live }}</ref> as well as freezing water in valveless pipes to enable repair.<ref name=PM159>{{cite journal |date=July 1960 |author1=Mundis, Warren J. |title=Dry Ice as a Plumbing Aid |journal=Popular Science |volume=177 |issue=1 |page=159 |url=https://books.google.com/books?id=VCYDAAAAMBAJ&pg=PA159 |access-date=2016-09-23 |archive-date=2013-06-04 |archive-url=https://web.archive.org/web/20130604035651/http://books.google.com/books?id=VCYDAAAAMBAJ&pg=PA159 |url-status=live }}</ref>

One of the largest mechanical uses of dry ice is [[Dry ice blasting|blast cleaning]]. Dry ice pellets are shot from a nozzle with [[compressed air]], combining the power of the speed of the pellets with the action of the sublimation. This can remove residues from industrial equipment. Examples of materials removed include ink, glue, oil, paint, mold and rubber. Dry ice blasting can replace sandblasting, steam blasting, water blasting or solvent blasting. The primary environmental residue of dry ice blasting is the sublimed CO<sub>2</sub>, thus making it a useful technique where residues from other blasting techniques are undesirable.<ref>{{cite news|last=Wolcott |first=John |title=Ice-blasting firm offers a cool way to clean up |newspaper=The Daily Herald |date=January 2008 |url=http://www.heraldbusinessjournal.com/archive/jan08/iceblasting-jan08.htm |access-date=2008-01-20 |url-status=dead |archive-url=https://web.archive.org/web/20080109001112/http://www.heraldbusinessjournal.com/archive/jan08/iceblasting-jan08.htm |archive-date=January 9, 2008 }}</ref> Recently, blast cleaning has been introduced as a method of removing smoke damage from structures after fires.

Dry ice is also useful for the de-gassing of flammable vapours from storage tanks&nbsp;— the sublimation of dry ice pellets inside an emptied and vented tank causes an outrush of CO<sub>2</sub> that carries with it the flammable vapours.<ref>{{cite web |last=Pamech |title=Application in industry |url=https://pamech.pl/zastosowanie-w-przemysle/ |date=7 November 2023 }}</ref>

The removal and fitting of [[cylinder liner]]s in large engines requires the use of dry ice to chill and thus shrink the liner so that it freely slides into the engine block. When the liner then warms up, it expands, and the resulting [[interference fit]] holds it tightly in place. Similar procedures may be used in fabricating mechanical assemblies with a high resultant strength, replacing the need for pins, keys or welds.<ref>{{cite web|url=http://www.engineersedge.com/bearing/bushing_press_fit.htm|title=Bushing and Plain Bearings Press or Shrink Fit Design and Application – Engineers Edge|work=engineersedge.com|access-date=6 July 2015|archive-date=7 July 2015|archive-url=https://web.archive.org/web/20150707024750/http://www.engineersedge.com/bearing/bushing_press_fit.htm|url-status=live}}</ref>

Dry ice has found its application in construction for [[Ground freezing|freezing soil]], serving as an effective alternative to [[liquid nitrogen]].<ref>{{Cite journal |last1=Shuplik |first1=Mikhail |last2=Nikolaev |first2=Petr |date=2019 |title=Advanced ground freezing method and its applications in underground construction |url=https://www.matec-conferences.org/articles/matecconf/abs/2019/14/matecconf_gccets2018_04021/matecconf_gccets2018_04021.html |journal=MATEC Web of Conferences |language=en |volume=265 |pages=04021 |doi=10.1051/matecconf/201926504021 |issn=2261-236X}}</ref> This method reduces the soil temperature to approximately -70 to -74 °C, rapidly freezing the groundwater. As a result, the soil's strength and impermeability significantly increase,<ref>{{Cite journal |last1=Ren |first1=Zhifeng |last2=Liu |first2=Jiankun |last3=Jiang |first3=Haiqiang |last4=Wang |first4=Enliang |date=2023-01-01 |title=Experimental study and simulation for unfrozen water and compressive strength of frozen soil based on artificial freezing technology |url=https://www.sciencedirect.com/science/article/pii/S0165232X22002300 |journal=Cold Regions Science and Technology |volume=205 |pages=103711 |doi=10.1016/j.coldregions.2022.103711 |bibcode=2023CRST..20503711R |issn=0165-232X}}</ref> which is essential for the safe execution of underground construction projects.<ref>{{Cite journal |last1=Nikolaev |first1=Petr |last2=Sedighi |first2=Majid |last3=Rajabi |first3=Hamid |last4=Pankratenko |first4=Alexander |date=2022-12-01 |title=Artificial ground freezing by solid carbon dioxide – Analysis of thermal performance |journal=Tunnelling and Underground Space Technology |volume=130 |pages=104741 |doi=10.1016/j.tust.2022.104741 |bibcode=2022TUSTI.13004741N |issn=0886-7798|doi-access=free }}</ref>

It is also useful as a [[cutting fluid#CO2 Coolant|cutting fluid]].
