I'm having a hard time finding concrete info on what I need to do to start a company.

Fill them with concrete gap filler.

I always go with...tile, laminent, or stained concrete...depending on the location and subfloor.

We got the cork backed fancy NuCore with 6-mil top layer (waterproof and lifetime warranty for residential and 15 year for commercial) for $2.89/square ft -- that just needs a moisture underlayment @$.11/ square ft over a concrete subfloor and doesn't need anything over tile or any other kind of subfloor. 

I am just cutting the carpet, throwing up drywall, digging the egress window and breaking up that small concrete section outside.

So I have to build fire escapes, concrete enclosed furnished room, as well as sprinklers throughout the building.

We've been reimbursed for adding columns and concrete work in basement, etc. 

He did this through not just his celebrity status, good looks and silver tongue, but also with a well designed and polished high pressure sales program that relied on fear of missing out and classic bait and switch tactics to rush customers into bad decisions without conducting inspections, getting appraisals or any of the usual due diligence.

The worst thing you want happen is a tenant moving out forcefully and retaliating like pouring concrete down the drain or punching holes in the walls. 

(i.e. the concrete steps) I'm really just interested in the content (and the scripts), not the whole JV thing.
