Hi. After some advice regarding a bump in a floor I'm about to screed. The raised part is 30cm diameter approximate, raised about 25mm. Whats the best way to get rid? I though a heat gun and melt it, scrape off the excess. All advice is greatly appreciated.
Ashpalt Could be a tree growing under that. I’d smash it up with a hammer then rapid repair screed it with a liquid dpm thrown in.
Last time I had that with asphalt I dug out the bulge filled with A46 then 404 dpm over the lot 280 primer and layed uzin reinforcement mesh over the repair before screeding Worked a treat
I think when doing sufloor repairs you definitely have to consider longevity rather than just a quick fix
