In the course of most, if not all, projects, there are moments when all of the hard work of preparation become manifest in a sudden and visceral way. Such is the case with my “big” concrete pour. Well, “big” is relative. Many concrete pours are measured in hundreds of cubic yards and many concrete trucks. Mine was about 10 yards, which was a pretty full truck, but, hey, have you ever had to move 10 yards of anything by hand? To me, this falls into the category of “big”.
This was “big” in another context as well. It marked a big turning point in the outdoor part of the project because, in a matter of a few hours, it transformed the front of my house from a bunch of shabby looking trenches into something that was actually warm and inviting. And that’s how projects go. Lots of preparation with little apparent visual progress, and then, boom. it’s all done.
The first thing I needed to do was to find a suitable contractor who would do the pour and finishing. I have tried to do some concrete work by myself, or by enlisting the help of some of my family members and friends. Some of these turned out OK. Others were major disasters. Bottom line is that through experience, I had learned that a concrete pour, especially of the size which I had planned, was something left to the pros. There are things that are NOT DIY and this is one of them! Concrete has a relatively short working time, and the crew that showed up numbered 9 people, if you include the truck driver, pump operator, and the owner/supervisor. No way can that be duplicated at the DIY level. I got a few bids by calling some contractors that were advertising on Angie’s list, and I chose a company that (a) showed up on time, (b) gave me an estimate that was competitive and (c) told it like it was. The owner had been in the concrete business since he was a teenager and knows concrete from the bottom-up, inside-out, over-under, well you get the idea. Here is a link to his website in case you’re interested. The owner’s name is Dave Parker and he gave me several suggestions on how to improve some significant details of my design (which I took on board). We had sealed the deal and, because I had everything set up, he was able to work me into his schedule last Saturday.
Saturday morning arrived, and it was a good thing that I am on an “early” schedule. My alarm goes off at 4:00 AM and I’m usually on the job not later than 6:00 AM, whether that be my day job or my remodeling adventure. The crew arrived at about 6:45 AM and I walked the foreman through the project. As additional workers started to show up, they started doing the layout. Although I had set the forms, they snapped chalk lines against the walls to make sure they had a good reference to work to, and did some clean-up. Eventually, the owner shows up and gives his crew some specific directions based on my walk-through with him a couple of days before. Then comes the concrete pump. Nowadays, concrete pumps are ubiquitous. No pros EVER use anything but a pump. It’s a relatively small part of the total job (for me about 17% of the total cost) and that would be about the same as the labor for barrowing the stuff around. At any rate, the concrete pump and the associated truck which pulls it takes up a significant amount of frontage. Then comes the concrete truck. Fortunately, I had made good use of my traffic barriers to block out any stray cars from the front of my house, as well as my two adjoining neighbors to fit the whole rig in. But,hey, it was early on a Saturday, so the first inkling that they had regarding my occupation of “their” parking spaces was a big concrete truck in reverse with its warning beepers at full blast. So much for sleeping in. Such is the price of progress.
So things were getting exciting. For the rest of the event, I invite you to watch the following video.
To me, working concrete is an amazing skill. Or perhaps it is art. Your medium is this heavy, messy, wet stuff that looks like, well, you can draw your own conclusions after reflecting on the video of the stuff coming out of the hose. Yet a good concrete finisher will direct the pour to align the edges perfectly to the forms and/or lines, and then sculpt swales and mounds to get the water to drain properly. The stuff has a certain working time, so one has to be cognizant of that and work accordingly (usually fast). However, there is a “sweet spot” of time when the concrete just begins to harden, and that’s where the magic of a good finisher shows itself. The guys I had were expert. They poked, prodded, screeded, floated, sculpted, troweled, cut control joints, finished the edges, and finished it off (I wanted a broom finish*) in what seemed to me a well orchestrated ballet. Literally, they were dancing on top of the forms and whatever else the could gain purchase on to do the finishing under the pressure of the clock. Baryshnikov would have been proud!
Here are some pictures of the finished product:
I’m really happy about how this came out, and it represents a big step because it is not only the culmination of a lot of hard work, but also had an immediate, positive, visual impact on how the project is shaping up.
Now… onto the back yard!
* A broom finish is where you take a stiff bristle broom and push it across the wet concrete. The result is a surface with a lot of tiny parallel grooves which produce a non-skid surface. This finish is standard for any concrete which will have foot traffic. Your driveway is probably finished like this as well, because you’re probably going to walk on it. However, on public roads, the shallow grooves of the broom would wear down rapidly. So, the builders will frequently cut big grooves with a concrete saw to not only provide traction, but also to shed water, which, when it rains, is a significant hazard.
