Yes the virating time for this size is as you see it. Its done here on a wooden shed floor so that helps with the process of vibrating. The mix is 300kg of cement to the ton of concrete. So about 1 part cement to 6 parts of aggregate. Concrete fiber for strength and waterproofer is added to the mix.
@@felixbrunner5707 Excellent , they look a good job . The reason I have enquired is that I have an odd size stone wall and I have to make custom copings . I know that it is essential to get all the air pockets removed . Many thanks for your help and reply
@@felixbrunner5707 Only once , I intend to weld up a metal form , with removable ends . The copings are 1 metre long by 550mm wide . The plan is to make base from quarter inch plate , add a 22mm box iron inner step to create a decorative edge , then case outer sides with 2 inch box iron . I will use an air chisel to vibrate out the air pockets . Well thats the plan anyway
@@ringsidejudge4302 metal is good, wood helps with pulling moisture out of the slab. As it will allow moisture to migrate through the wood. Anyhow thats what i learnt. I would be interesred to learn of how you get on with them. I am not able to fo much anymore as i contracted prostate cancer 8 months ago and its playing games with my body. I am trying to pass on building knowledge now whilst learning still.
Good video , vegetable oil works well as a releasing agent and doesn't stain thanks for posting bren
Ok thanks, for the advise, ill try that, save a load of money...
Nice job . What a lot of copings to make , could you elaborate on mix please . Is this the actual time that you spend on vibrating .

Did you build the forms yourself?
Yes, i measured the existing coping stones and made the form acordingly to the same measurements.
