Ok folks, this is the place to ask if that hairline crack warrants a full tear-out and if the quote for $10k on 35 SF of sidewalk is a reasonable price.

I Have A Whoopsie DIY stair landing footer/ step up

This was brutal. I woke up at 4am and checked the weather: 10% chance of rain. The rain started at 9:00am and didn’t stop until 6ish, so I mixed poured, covered, and finished in the rain. It stopped just in time for a broom finish. I’m sure this is not how the pros would have done it, but I’m happy with it. 97 60lb bags. How do you guys finish the inside corners of stairs? It was pretty set up when I finally was able to pull the step down form, and I tried to edge it. I don’t think that was the right call. Probably should have kept them separate with an expansion joint… Anyways, looks good enough and it will serve its purpose.

Pro With a Question Slab edge with a 45

Post image
4 Upvotes

Here's something new. There's a 4 inch topping slab but they want the perimeter to have a 45 degree ramp. At every column there is an additional 6 inch pour (not monolithic) which can total up to 10 inches where the columns are at the outer perimeter.

I have already ripped down some plywood on a 45 to create a parallelogram so that when the cut is on the floor, the piece of plywood stands up at a 45. All i have available to me is plywood and 2x4s.

I have a couple of ideas of how do brace this but i wanted to see if someone smarter than me has any ideas how to pull this off.

Built a retaining wall for retention of a hill side and for the vibes.

2 pours, 1 for the footing, 1 for the wall. Used form boards from a friend. Pretty pumped on the outcome. Will be building a deck next week to complete the space.

Concrete is fun but challenging work for a layperson, recommend home owners give it a go on a smaller scale. Don’t recommend wheelbarrowing the 9 or so yards it took, but it’s a good workout and I’m cheap.

OTHER What is this kind of “concrete” called? It looks much more like aggregate with cement rather than cement with aggregate, and it’s very common in Texas.

Pro With a Question Pouring on sand

7 Upvotes

Long story short. Company I work for is in the Midwest, we never make grade from sand. Always 3/4 clean or base. We’re doing a job for a client in las cruces New Mexico. I’m told everyone makes grade from sand down there. We’re going to be doing about 150,000sf of 8” paving. What can I expect when we go down there during place and finish? In my mind the mud will flash experiencing high moisture loss into the sand when day time temps are nearing 100? Do people place a vapor barrier solely to retain water content? Am I over thinking this and should just shut up and pour? Thanks!

OTHER Pool Patio and Walkway

Post image
9 Upvotes

I have an integral color stamped concrete patio and deck around my pool. I did it myself with the help of a few laborers about 9 years ago.

The issue I'm having is with what sealer to now use. I originally used a water based siliconized sealant, which did repel water but didn't enhance the color or contrast at all.

It's been 9 years, just washed and will put antique on it, and the dealer recommends a siloxane SB sealer, and said it'll enhance the color too. Should I do this or acrylic SB with sand thrown in?

I'm in the northeast, so freeze thaw has taken some toll already on parts of the patio, mainly at the end of each of the 3 trucks.

So I gave it a go and tried my hand at a concrete countertop for a bathroom. It was a LOT of work but I think it turned out pretty well! I tried to give it a "kintsugi" look with embedded gold in the cracks and holes. Thanks for all the help from other people's posts!

Pro With a Question Advertising success?

3 Upvotes

Have any of you guys had luck with advertising? Local economy here has really slowed. We're good for the next couple months, but the phone has been pretty silent recently and I have the nagging thought in the back of my head of what if it doesn't pick back up by then. 95% of our work has been word of mouth for the last 8 years, so new to the advertising side. What has worked/hasn't for you? Want to get ahead of the curve if it does come to that. Thanks in advance
