Chemicals are available to break down concrete

Breaking up concrete takes time, effort and physical strength. It's a grueling process, to be honest. But there are tools that can help you do this job.

Some chemicals used in concrete breaking

There are products on the construction market that can be used to break up or soften hardened concrete and make removal easier.

They are very toxic and should be used with care so that they do not cause damage.

Dexpan or Ecobust brand

This product comes in an 11-pound bucket of powder. All that is required is a series of holes in the hardened concrete surface.

Now pour the Dexpan product mixed with water to fill the holes, leave it overnight.

This component expands and breaks the hardened concrete into slightly smaller pieces.


  • With a large hole punch holes in the concrete, these should be one foot apart.
  • Drill to 80% depth, this should create a grid of several holes
  • ¬†Mix your solution: mix one liter of cold water with an 11 pound bag of Dexpan
  • After that is mixed, remove the Dexpan with a drill and a trowel. There should be no lumps in the mixture
  • Wait 15 minutes and then pour the demolition grout into the holes, this should be done very quickly
  • Any excess grout should be removed and the holes should be kept away from direct light, snow or rain
  • Now wait about 8 hours until some cracks appear, but you are not done yet: After the grout dries brush off the remains.
