Do you have any tips on pouring a concrete drive way that has a 30 degree slope.?

Question

Drive way will be 10 feet wide and 300 feet long by 4 inches thick

Answer 1

ask for a 3500 psi fibermix w/ 0% slump. This works pretty good for pouring swimming pool floors w/fiberglass walls, but before you order ask several companies what they recommend. Are you experienced? I had a subcontractor try pouring a similar slope once and I paid to have it jackhammered out which was mess. So be careful in your planning

Answer 2

Lay it in sections or alternatively, lay down a bottom layer of gravel and then pour a fine liquid concrete on top of the gravel--the gravel will hold the concrete in place while it dries.

Another possibility would be to mix a drier mix so it stays put.

Problem with my last two suggestions--the gravel idea would probably make for a weaker slab. The drier mix might do the same, as the strongest concrete is the finest, most liquid and slowest drying.

When my honey gets home from work I'll ask him. He is a cement finisher so he will know. He is pouring a slab today so he won't be home for awhile but as soon as he does I'll edit my answer. Good luck.

Hi I'm back my honey says start at the bottom of the 30 degree slope and pour your concrete stiff and in sections.

Answer 4

We did our driveway, 21 feet wide and 116 feet long, in sections at 25 degree slope. I recommend the sections heartily. Concrete has a fairly dense viscosity and will lend itslef to slopes.

Answer 5

Sections are good, you will also need to have the pour drier than normal, so let the concrete supplier know the degree of slope so they can bring you thicker material. It will set up faster also.

Answer 6

Have you looked into black top instead?? That's a lot of concrete and a lot of opportunity for cracking. If you're insistent on concrete, I'd consult a professional. Concrete forming, pouring and finishing is very hard work.

Answer 7

i dont think of your going to have issues at 30 ranges over night on clean concrete. if it warms up returned to 40 immediately and the suns out itl dry in basic terms effective. the ice on the exterior could be my greatest subject they possibly shoulda lined it with plastic. whats gonna be your saving grace is the incontrovertible fact that they only poured it the former day. clean concrete generates its very own warmth because it treatments. in basic terms tell your builder you want a guaranty in writing immediately on your information. maximum states require guarantee era on foundations besides. sturdy good fortune to you.

Answer 8

Start from the Lowest End...and Work Your Way Back1

Answer 9

Carefully.lol

Answer 10

Keep your mix as dry as you can handle, work from the bottom up, and work in sections to relieve the stress.
