Find out how to construct a slab for your application with this video. Sakrete offers a number of concrete mixes ideal for constructing concrete slabs. From high-strength to fast-setting to…

It’s a pretty good video. I wouldn’t rely on it entirely without knowing my
stuff before hand.
Where’s the finished product? It’s always nice to see the results…like
someone walking out the door and looking refreshed to finally see a
concrete slab there.
why wouldnt you center it infront of the door?
Is this 4 X 4 slab too small to reinforce with rebar? Won’t it crack, even
at 4″ thick?
4 inches is good—its just a walk way–not a drive way.
Interesting and well presented. It would be good to see the final work and
maybe an indication of how much this would have cost.
Slope slab away from building for water runoff (1/8″per foot is ‘rule of
thumb’).
any recamendations if i cant get sakrete?
I did 8 80 lbs bags on a project and will never attempt that again, I got
it done onder 3 hours and it looks great but my back killed me for 2
weeks….
Thanks for sharing.. True statement about the water.. it will weaken the
psi and will also make the concrete crack and in many cases will make the
top of the surface dusty and chip off when dried due to excessive amounts
of water trying to move out of the slab during the hydration stage.
A year or so ago, I poured over 20,000 pounds of concrete by hand on 2
separate projects. Mixed in a wheelbarrow~!…… By myself~!! Yea, I was
looking for my “stupid hat” after that. This was a perfect pour. Do NOT
think adding excess water will make less work. It doesn’t~! As stated in
the vid, it only compromises the integrity.
You need about eleven 60 pound bags to pour this slab, at about $2 per bag.
So you’re looking at about $22 plus about $5 in lumber.
Once the mix has set the frame can be removed. As for a brick surround this
can be done as well once the area has set enough that it will not be
disturbed when placing the mortar and brick.
probably the best basic cement work video on you tube this is the one to
watch
Yes, mist the surface of the slab for several days especially when the
temperatures are high. Do not over water, just a simple mist to keep it
damp.
do you need to tamp down the gravel or soil under the gravel at all? or is
it dump in, level off and ready to pour concrete?
I am very confused. I purchased a 80 lb bag of Sakrete concrete mix, the
same the one you are using, but there were a significant amount of rocks in
the concrete, it was not anywhere near as smooth as in this video, there
were visible large rocks. When I layed it down and tried to smooth it, you
can clearly see all the rocks at the surface. Can somebody please explain
what is going on?
Great job
very informative and simple! nice job, sakrete!
Very informative – I did not know you could use it with such a dry mixture.
Hi, great work..!…i would like to ask a question please help with
advice.—im looking to put large L shape or maybe square shape slabs over
concrete floor over at my parents house abroad. the council poured concrete
all over the little roads in this village and our floor of the house is now
9” inches lower than the road outside THUS rain water staying inside
(House is a bungalow type of property, very much open front area when you
enter the building)…Question – what the best way i do this?
There will always be aggregate in any concrete mix. The stones should “sink
down” to some degree when the mix is poured and then it can be troweled to
a smooth surface. If the mix is to dry this may cause a problem, and too
wet will cause cracking issues. The back of the bag will give you water
requirements for the mix.
Thanks for viewing. We want to keep the instructions for your projects
simple and precise.
