Basement Floor Fill & level - Contractor Talk - Professional Construction and Remodeling Forum

My basement floor has heaved cracks like a mountain range covering most of the area , i jack-hammered out the highest cracks and peaks and where they joined up ( pic attach ) .

Question was to fill and get back to reasonably level , what products would i use . A regular concrete mix to fill then a self-level over that . I will be installing carpet and some laminate over top with a nice underlay and a dimpled membrane for a little more give so it doesnt have to be 100%

Thanks,

Chris

Chris, welcome to CT, if you have not yet done it, go to the INTRO page and let the guys know a little about your proffesional exp, To answer your question, it looks like you have some pretty good size opening, get some crack resistent 80lb bags of sakrete or equal, fillem in, trowel them flush. Also, if it where my basement i would install those 2x2 floor panels that the box stores sell, this will create a nice barrier between the floor and the finish carpet, it softens thing up, and transfers much less cold and dampness to your finished space, sorry i dont know the name of the product.GMOD

Ya thanks , ive seen the Dri-core , since the floor isnt and probably wont be 100% level i didnt want to go with a "sturdy " underlay since it will just mimic the peaks and valleys in the floor , was going to use a dimpled membrane type like Ditra but one for carpet and laminate , one brand is called " All-in-One " and then use the foam that comes with the laminate and regular underlay under the carpet portions . It will give it more bounce and a little more give where i need it too

Not sure, maybe someone else will comment, i think the drycore might level out the floor more since it is rigid, it can span some of the imperfections, unlike a membrane that will conform to the floor perfectly, also the drylock, since the panel are 2x2, will flex and conform a bit as well. GMOD PS, you could also go with a MAPEI leveler after the main patchwork, that would really tighten things up.

I haven't tried myself, but have heard of people using delta MS dimpled drainage membrane, then sheeting over top. its much cheaper than the 2x2 panels

This is what i was thinking of using over the concrete then the foam and underlay for the carpet and laminate , i was just thinking over the high spots the membrane plus various underlays will 'float' over them better than a rigid product , but thats why im here ! not sure
