If you add fiber to concrete it will give it the strength to not crack as it cures. Rebar not required. A thickened edge of 8 inches deep, 12 to 18 wide is good. I had my dirt guy did one bucket wide around to edge. Make sure you have vapor barrier 10 mils. Pour at a slump of 4. Do not let...

X3 for the win

That looks like a standard door install. As long as there is structure to bolt the tracks you can have the opener as high as you want. Then you move the torsion bar up. If you paid of a high lift you did not get it. For a high lift you get longer cables and track. I do see that. He can...

You need to look at the specs of the unit. How much heat will it make as it gets colder. I have a LG red unit that will heat down to 10 degs and works like a champ. Look at AC wholesalers.$$$ for price on the LG. MR cool is bottom of the line, but they do work. You do need a vacuum pump and...

A Battery will not explode from over charging. During changing there is hydrogen is released. There was a spark from somewhere to ignite it. If batteries explode very often you would see cars at the side of the road.

This is usually a handling issue. The bus bar is lead. If the battery is dropped or hit, the bar can break. I have not seen a charger find this issue. If a battery is putting out current and then stops this will likely be the cause, once bad connection are eliminated.

This is a case where the battery had a broken bus bar. It would provide voltage when the two pieces touched and no voltage when they did not. There was a spark when they touched. There was hydrogen from changing the battery and the spark set it off. BANG. Replacing the batteries will not...

Hi Go here pay the money. https://ddmgaragedoors.com/diy-instructions/garage-door-high-lift-conversion.php Be careful the twisty spring on a rod can kill you. Get the sidewinder thing. If you are not careful you will end up in hospital.

Looks like they added to much water. This does not look like bad base under the concrete. Did you keep the top wet for the first week? Do you have a vapor barrier underneath? If it has sat for 6 weeks then most of the water that was in there has come out. I would bet that it has settled...

When I built my garage I did the high lift when I put the door in. I got an 8500 for an opener. The new stuff from DDM Garage doors. Make sure you get a S3 spring winder. Opener was 300 and the parts were 300. Labor was free and the job was not that hard.

I would use epoxy. It goes on in a thick coating. Hard as rocks.

I thought that the requirement for a lift was 4 inches of 3000 PSI concrete. Am I wrong?

I made mine 40 wide. I wish I would have made it 48 foot wide. I used 4 foot LED fixtures in the bay with a lift. They are mounted to the sides of the bay and tipped toward the center. I used four on each side end to end. I would not use that much rebar. I would use the fiber that is...

I just ordered doors from Lowes that had torsion springs. They were cheep and insulated. Worked with wall mounted opener. Also you can insulate the doors you have if you are on budget. I made one a high lift so the tracks would not get in the way of my lift. That is another story.

What you have is shrinkage cracks. Too much water was added to the mix. As the water evaporated the concrete got smaller. The concrete did not have the strength it needed not to crack. The water has to be held in the mix till it gains strength as it cures. Did the concrete have a vapor...
