Current slab can be removed with hand tools, concrete can be bought by volume or prepared on site. 

Trench Drain Installation within an existing concrete parking lot (roughly 75' length)3.

However, in the urban core, there are pockets of “ok” blocks or streets, I could definitely tell a difference as I drove through.  

Unfortunately they weren't the shining stars I was hoping for so I'm curious about a few items as I haven't been able to get any concrete answers from my research.1.

I did this because I have aspirations to invest internationally in several locations in central and south America and didn't want to just talk the talk or be a wantrepreneur, rather put myself in the field and put the building blocks together myself..I am currently waiting for the CA Bureau to approve my license application so I can take the test to receive my RE license (completed the course work in Spring of 2018 while going to school full time, working part time).

Our contractor said that he would pour concrete to fill up the cracks, which he did.

Depending on what street (as there are some pretty nice blocks over there) rent could be increased.

(Look at a 6 house block and tell me how many are for sale, (the inventory is zero or a large percent.) or include 10 new houses in a 40 house neighborhood sold for $400k last year and only smaller used houses sold this year for $200k, prices have dropped 50%.) 

I am focusing on B neighborhoods and since the rents and prices vary by the block within hot neigbhourhoods, I am having a challenge zeroing on a few.

If there is one, where do I find the setting to block someone, so I don't see their posts?
