BONDING CONCRETE TO EXISTING CONCRETE.

in this video, I show you how to bond concrete to existing concrete, first, you got to score up the existing concrete using a saw/cutter then you have to prime up the area, also add the primer to your mix just follow the instructions on the label I also added concrete fiber mesh follow instructions on this to. The concrete slab went from 4inch to 18mm over 8foot: I also used a Marshalltown edging trowel to get a perfect finish on the concrete including the finish from existing concrete to the new. In the concrete was 12mm rebar mesh:

For the concrete connection layer, you have to roll the connection layer and then pour concrete right away, right? Roll it so it dries out the connecting layer?

@@creativecrambo thanks for the content. Like the channel. I did a join similar on a driveway many years ago and we used the chemical joiner but did not use fibre in the cement and it cracked.

@@tonytanou thanks for the kind words Tony 👊🫡nice one 👍
Yeah driveways have alot of traffic mate 💯 especially to the front of the drive the thing is mate we all live and learn I've made some bad choices over the years and have learned from my own mistakes but I've never made the same mistake twice lol 😆 thanks for the reply mate I like talking to people who have something constructive to say and will always make the time for someone like yourself and others cheers mate and happy new year to you 👍 👍👊🫡

Is the primer just concrete glue?
What is the fiber has to do with bonding?
You need to vibrate the new concrete for a better surface to surface adhesion.

[@tonytanou]

If the concrete is subjected to heavy traffic I would had chipped in a 25 mm step at the sloped joining section. Should be fine for foot traffic

[@creativecrambo]

Thanks for stopping by the vid Tony nice one mate👍👊 yeah totally agree mate, the pathway is only used as an amergency fire escape there for used for foot traffic plus any maintenance vehicles would be lightweight to thanks for your feedback mate appreciate it alot 👍 👊

If I pour concrete retaining wall one section at a time leaving rebar sticking out to tie into the next section and keying new wall into the old one, is it likely to leak and stopping me from installing stone veneer on top of the cold joint successfully? Is there a method to do this successfully? Thank you

[@creativecrambo]

Hi Hos thanks for stopping by the vid mate 👍
Normally when I do a retaining wall say using hollow concrete blocks with rebar I'd normally get the concrete in the blocks then the next day do the face work plus work from expansion joint to expansion joint if that makes sense not sure what retaining wall your doing but sounds like you need the concrete to set before you move on to the next part so you don't get any bleeding through from the concrete thanks for your feedback mate appreciate it 👍 👊

@@creativecrambo thanks for replying and the advice

No prob mate and hope it works out OK for you 👍 👊

[@giobelkoicenter]

what paint you used as primer?

[@crispycat7412]

he used SBR the yellow bottle, description around: 0:40

[@michaelrussell8921]

Do you recommend anything for curing? Thanks.

[@creativecrambo]

Curing is a process of a chemical reaction with the cement and what you put in to that cement , I'd recommend 2 days before you walk on freshly laid concrete give it a week and you can drive on it , if you were to add a hardener epoxy resin into the mix it would go off very quick and you would struggle to get a finish on the concrete the best results are to let the concrete harden up itself then get the final finish, thanks for stopping by the vid Michael 👊👍👍.

Juat wondering if you are around? I have a crumbling shed cocnrete slab due to freeze thaw. What can i do

[@creativecrambo]

To be honest mate that sounds like a job for superman appreciate you stopping by the vid mate hope you get it all sorted that comment made no sense to me at all 🤦

[@bobmarley9712]

@creativecrambo hahaha sorry!!!
I got a concrete slab made for a shed. It's been 3 months not put the shed up, and I think due to freeze thaw weather it's sides have crumbled a bit and the top layer has all spalled/is peeled off. So like if I brush it it'll all just come off. The sides, on some parts have gone in due to the cocnrete falling off

[@bobmarley9712]

@@creativecrambo laughing my ass off now reading my comment

[@smallnuts2]

If I need to add an inch to existing concrete for height. To level up with the other side, Do I use bonding and then cement? Or will that concrete leveler be enough 🤔 and not use concrete to fix height?.
