Cost aside, to pour a suspended slab using hand mix will cause cold joints which which will compromise the integrity of the slab. Pre-mix using a pump to get that concrete in place as fast as possible is the only way to do it properly.
Valuable information right here. Thank you 🙏🏽
Really would like to contact you
Thank you so much. Happy I found this channel.
Thanks for watching. Welcome to the DIY family.
Great stuff Rory. Looking forward to more videos. You're one of the best at giving details. Thank you. 👊🏾🇬🇧🇯🇲

Great info man
Thanks for this valuable info.
Very Helpful video, thanks for making it so easy.
We are always glad to share information and what we have learned along the way.
Very informative. Thank you.
Thank you so much for your very informative building information I do appreciated
No problem. Thanks for watching!
Thank you bro really 'concrete information, I'm doing a small renovation and this info assist me a lot especially with the cost of the props
No problem. All the best with your project.
As always, very informative
We are glad to share, great that you found the video informative
Excellent video, the price for the premix is good because on some sites the owner has to cook food and buy alcohol so the labor would be more if food and beverage are included.
Yes that is true, some work men cant function without rum.
I use pre mix for 3 floor of my house and it’s faster time. I think it’s more expensive. But it way less headache and
Stronger result
House building is a lot. But it’s a great experience
This was very helpful
Thank you for the information. Have me thinking now. Not sure what I will do as I’m just about at the point to make this decision. Premix in Montego Bay is extremely expensive but I’ll compare prices and make my decision afterwards. Thanks again.
Yes. Please compare and consider time and quality too. All the best
Thus was helpful. Thank you
You are welcome, stay tuned for more informative content.
Good inform. Thank you 👍🏾👍🏾
My pleasure, hope it helps in guiding your decision
Thanks a lot thanks in a million great information 🇺🇲👍
Glad the info was helpful
Good information
It also depends where your location is. Thanks for the information. 😊
That is true, prices vary
Great thanks for this video I needed to hear this to confirm my decision
Glad to help, let us know your decision
@@HackedbyEbanks sure
👍. Good narration. Of course it will be helpful,even if One isn’t building,Information can be passed to whomever needs it. The old adage says one is never too old to learn,and I know none knows it all, so I am not ashamed to declare my ignorance…never heard of such measurements!!😀. However, I will use my common sense. Keep Progressing 👍🙏.
My pleasure, glad the information is well received, never too old to learn.
👍👍👍
Yow yuh program good bro we need more videos love the explaning
Bless up! More videos soon drop.
Very good
Yes you are right although yes the premix can be expensive but it is better than manual mix unless they are going to use a concrete mixer
Agreed, consistency and time is important when building.
Good night great information save me some money Thank you for the information
Great, glad we can help.
Hello I found your video so timely and informative
Could you post the companies that does premix..I'd appreciate that a lot
Thanks for watching Jo-Seon. We’re happy to help. Readymix companies include Premix, Kenetic, Coast to coast are the big ones. We used coast to coast.
Very helpful
My pleasure, always happy to help.
Thanks for the info! I’m about to do cast my decking, and vowed when I was casting the footing/foundation it was total chaos..lots of workmen, very lazy, and too much noise and expletives on the site. Thank you.
Sounds like a typical construction site in Jamaica. Pouring not only saves you from that experience but you definitely will get a more consistent pour which is less likely to leak. All the best with your project.
@@HackedbyEbanks thank you. What’s the name of the concrete company?
@@jamminwiththerichards6442 we used Coast to Coast Concrete.
@@HackedbyEbanks thank you
The headache with manual mixing is the main drawback, but it's much cheaper.
For a driveway or sidewalk, light duty, then 5 bags cement per cubic yard might be OK but, for a strong deck you usually want 6-7 bags of portland per cubic yard, 6 being most common. Most premix that I have talked with brag that they use 7 bag mix through the pumps..
you save on pre-mix because you do not spend as much on labour, or food for labour, or time moving it or rented buckets and barrows. No rum buying. No cussing usually. and at least the white river and ocho rios companies both are done quickly. I use steel props for a week, then interspace with bamboo, and wood props that I leave longer.
3000 psi is 6 bag concrete-- or bag concrete, barrow sand, barrow grit or gravel.. add plasticisor to it if you need extra time.
2500 psi is standard mix- bag concrete, barrow sand, barrow and a half of gravel. 2000 is extra half barrow gravel.
Cut the water added by using plastcizers to the mix to reduce the water, as water decreases strength.
final note- every other prop can be removed after 1 week on most mixes. After two weeks, most props can be removed if not loading deck above, but, if loading or building on deck above really should leave the props for 30 days. I normally use bamboo or wood props for the main (30 day) props and rent the ones that go between so I can turn them back to rental sooner. As long as ends of supports are tied to outer walls, you may be able to strip all props by end of week 2, then strip the forms after 3-4 weeks.. Now, when I did commercial work that combined plasticisor with quickeners and concrete glass fibre reinforcement as well, we poured today, stripped 80% of the forms tomorrow, moving them upstairs, and setting up deck 3 with forms from deck 1, etc.. so by the time we got to deck 5 we were totally stripped on deck 1, with crews laying in electrical and plumbing there, and strippers were finishing form stripping on deck3, and support stripping finals on deck 2, and support first strip on deck 4.. but that was some massive and quick work, nothing like here in Jamaica.
@@brotheradam those reasons are very important in going the premix avenue, especially the rum buying. Lol. Interesting mix of the props usage btw, thats a good way to have them up longer while controlling cost. We did leave up some of our support while building above until we needed the forms to create the other deck. The commercial build sound exciting and fast paced, lots of coordination also. I have watched a few overseas building approach and thats how they do it to save time, every 12 hour they can pour a deck with the additives and support
@@brotheradam Thanks for this breakdown to achieve the psi strength needed, I am not sure if many workmen follow these ratio. For out foundation which we did manual mix, we used 1.5 bags of cement per barrow as we wanted a strong mix and high psi
I went with premix to deck my house 🏠 in June,I'm running from inconsistent of manually mixing. Trying to avoid alot of roof leaking down the road.
Thats one of the main reason when you are decking, you want to maintain the consistency of the mixture and want everything to dry at the same time to help minimize cracks. If not properly cured, even premix can still leak.
@@HackedbyEbanks for sure
Can you give me the number for the premix you use please
Agree. Nobody should go through what I did with a leaked and sweaty slab roof from cold joints with manual mixing. I will always encourage everyone to use premix for foundations and slab roofs.
Let us know below if you will be using premix or manual mix.
This just popped up on FB and I decided to watch as I am supervising on behalf of a relative. Excellent information as we had decided on premix and you have made it easier based on your experience. Where are the props people located?
Happy to help Verone. The props people are A1 Equipment and they are both in Kingston and Mandeville. All the best with your construction.
Thank you for this very informative info esp on spec Crete and precrete. I didn't realise Jamaica had this building product as of yet. Can this product be found in hardware stores in Mandeville, Port Maria or May Pen?
Hello. Thanks for watching. Not sure about the availability of the product outside of Kingston but i believe the company (located on Mandela Highway) offers islandwide delivery.
This is helping me.. I'm about to start my house
Always happy to help another home owner. All the best with your build.
Ja is doing well,but only for those who can afford the same for black africka it is good for those who can afford
Whats your thoughts on ICF building method? Thats the foam construction.
We started doing some research on it before we started our renovation but I didn’t get enough details about doing a 2 storey building with it and also our building plans weren’t approved for that method. Hopefully in the future we will have a project using the ICF method.
Thanks for the information. Do they do work in Negril area?
Well them name coast to coast to likely but call and find out.
Labor cost yes - the unfortunate reality is that I you don't have a watchman in most locations, your material will go missing. I cost you forgot
Thanks for that. It is in fact a cost that some persons will have to consider
My bro wat is the best materials even if it's expensive to stop a poorly built slab ceiling from leaking especially recently from this rain downpour jamaica had and having 🤔🤔🤔 tnx
Hey. You can try pouring another layer of concrete and ensure you water it. We also used roof compound and thinest on ours to seal it. Theres also a a water proofing membrane that is usually used in the shower floor that you can try.
Lots of options. All the best with fixing it. A leaky roof can be a nightmare.
@@HackedbyEbanks its a nightmare ive tried extra concrete, thin set,slope the roof ,didn't work
@@paulostyles9484 you can definitely try the roof membrane that they use a torch to burn onto the deck and also seal it with the compound in the joints. The roof compound also works if you apply multiple coats on the concrete.
@@HackedbyEbanks tnx my bro is there a name of a compound u can recommend 🤔🤔
Slope the roof and steel float it.
Very informative, but that little deck was 11 cubic yards? What were the dimensions?
Glad you found the video helpful. The dimensions are 11 feet x 27 feet plus we poured the belting with the premix and a few of the columns.
@@HackedbyEbanks Oh ok. Thanks. I got scared there a bit, haha
What's the best advice to give when building
Theres so much but building isnt easy and there will be many challenges. Just stY the course and try to find workers you can trust, get referrals if you have to.
How much do they went ply and 2*4 for ?
Hi we had purchased our ply and lumber and resell what we didn’t use afterwards. We normally rent items from AOne equipment rental
How do they stay in business at 15 bucks per day for the props rental?
They rent other construction equipment as well and they are a shipping company. I guess it probably their marketing strategy. Not sure how it works for them.
Transportation costs hella high! Eating up much more of my budget than you identify!
Where does A1 Equipment located in Jamaica?
Hello Winsome. They have a location in Mandeville and another in Kingston
I'm interested. Where is this place I can get some props
Its A1 equipment rentals.
Which company did you use?
Coast to Coast Concrete
Rent a mixer, that will make it
Good channel but you need to research the terms a little more. The method is called ready mix. Premix is the name of the company and it's not manual decking it's called hand mix placing. Also the methods of ratio is incorrect in the lab and that has been established it's 7-8 bags cement per cubic yard. 5 will be on the weak side lastly not reigning on your channel but u have to understand that you have other professionals that will view your channel so just have an open mind
Hello John. Thanks for your input here. This may be a case of “doctors differ, patients die”. On a more serious note, our research is correct that to get 3000 psi strength 5-6 bag of cement per cubic yard is acceptable, with the correct ratio of water plus the sand (binding agent). 7-8 bags with less water and less sand would give a mix closer to 4000 psi strength which is definitely stronger. So all depends on what you’re going for.
Also, no hard feelings at all we are always open to suggestions. The goal is to learn daily so we can share and help others.
Everything that we do as black people no matter where we are is very expensive we need to be like in a gang so we can get the equipment to help each other to make things cheaper we need a way round this expensive system to me there is a conspiracy going on
Could you send me the address or telephone for AONE

Very detailed... Great stuff@REMFINISHES
