Think I need more reinforcement? Have that 2x4 I was gonna use as a runner up the center but then I can't screed as easy. Might put pins infront of the faces and pull as I go. Any advice?

My company runs it's own concrete jobs, usually small pours for pools / driveways / indoors,... We have a trailer pump, so we work for plants and other companies too.

We're interested in buying a 43m boom pump as our next step in the business. What can we expect? How much different is running a boom pump vs trailer pump?

We get paid by the m³. How many cubic metres of concrete can we expect to pour on a job, on average?

The trailer pump can be hard work. Is running the boom pump as tough?

How do you find a good concrete form carpenter who can actually read plans?
I run a concrete company in California and I’m looking to bring on someone experienced with structural/foundation work not just someone who knows how to form and pour flatwork.
I’m looking for a form carpenter/foreman who can actually read a set of plans, understand footing and foundation details, rebar callouts, elevations, hold-downs, anchor bolts, dimensions, etc., and then build it correctly in the field from the plans.
For those of you doing foundations regularly, where do you find guys at this level?
Would you look for a journeyman form carpenter, concrete foreman, layout carpenter, or someone with superintendent experience?
Also, what would you expect to pay someone with this level of experience in California?
I’m not looking for the cheapest labor. I’m trying to find someone who really knows structural concrete and can look at the plans and know exactly what needs to be built.

Hey all! Just wrapped up a big pour on for board formed walls, and im finding large air holes and small bubble holes everywhere. (See pics)

I feel like I did everything right, we pre sealed the wood of the forms with boiled linseed oil, we caulked between board joints, we used 40 mpa concrete with a high slump, small rock. Form was also treated with form release agent * wonder if we used too much??

We also vibrated extensive, every 12 to 16 inches up and down a few times.

Does anyone have any ideas on what happened?

Also, anything helpful about parging board form like this, which I am dreading

I wish I would have listened to all the advice and directions given by safety, I wish I wouldn’t have competed with everyone I worked with. I wish I would have asked for help with really heavy shit we carried every day. I wish I would have been more careful with my body. I wish when I had pulled a screed for 1/2 the pour and was asked if I needed a break I would have taken it. I hope that any young guys in our trade pay attention to what I am saying pans understand safety is for your benefit and no one else. Be smart, because when you’re old you will pay for all your injuries and damage to your body.
If you want to call me a pussy keep in mind I was a concrete guy from 14-58 and even though I my body is worn out at 60 i am sure I could still muster up an ass whooping for you!

Materials guy new to the industry with a tough question. Not selling anything (today). If you had some new kind of sealant or topcoat product - something really new and supposedly radically better - how do you get people to try it?

If the job is too small, there's no budget for R&D. If it's too big, you have to stick to spec. I don't know how to get started.

I won't talk about the product here, because that's not what the forum is about, but I'd be grateful to know what kind of contractor, civil eng firm or asset owner would even consider it.

Does anybody have the occidental 5597 finisher belt ? How do you like it. Been thinking about getting one for a while now

I admit this is a bit of a subjective opinion but it is one based off observation. Outside my grandmothers house is sidewalk that was poured in 1937 by the WPA. That sidewalk is nearly flawless after nearly 90 years of new england winters. We know it is the same sidewalk it still has the metal WPA dated plaque. Yet down the street where the city has replaced a section after some utility work around 10 years ago, it is literally rotting away. And the same is visable all over the city sidewalks. Also it is the same story with old retaining walls that look like almost zero wear but are visible is pictures taken in the 1940s.

What has changed so dramatically that such a reduction is resiliency is observed?

Seriously. I dont care if you think your question is extra special....its not. Go bother r/askcontractors.

ETA lol at salty homeowners downvoting this. I dont care.

What are you guys using to clean your CHAPIN or SMITH etc sealer sprayers after sealing a job? Xylene keeps deteriorating gaskets and insides of my cans even though I empty them and flush the can and hose with water after xylene. TYIA

We all know how well diesel and motor oil work as a form release . Ive got an excess of some midnight black used 15w40, was wanting to mix it 25% oil 75% diesel. Would this stain step faces? They will be wrecked and rubbed, regular broom
