flat roof construction and waterproofing

on a roof with a standing wall, its best to have a capping beams or a coping with concrete which can help direct water flow.. a capping with a 50mm edge out side the wall.

for a concrete roof skirting must be done atlease 100mm high.. liquid bitumen is one the best water proofing matrial that is been used.

 

As below.. many layers of material is best specially for a wooden roof but if its a concrete slab its not that nessary for this must of roofing felt or bitunen layers since concrete it self is water proof.

Even if its a concrete or wood, even though its a flat rood it need atleast 3% slope .. if not as below there are high chances of water leaking.

 

list of recent Tallest buildings

Still the world tallest building is in dubai UAE burj khalifa standing 828 meter., next Shanghai China Shanghai tower, mecca saudi arabia with mekka clock tower standing 601 meter.

Mostly European haven't made much progress in climbing the world tall towers.. kinda disappointing with what they claims.

Gantry crane to lift cement blocks

I notice the new workers are too lazy, so decided to make a something that can grabe the cement block pallets and go. cement blocks was about 80 kg in weight.. so it was also kind of heavy to move all day.

So ive made the above model from CNC laser machine i have , out of plywood, check out my youtube channel on how to make it. https://www.youtube.com/c/Goldinton

Seems to work well with the grabbing design.. so next was to design a gantry crane that can move this pallet one side to other.

Above pic is using 2 lazy worker to grab the pallet n stack it. 🤦‍♂️ time consuming n dependable on them, not practical for a production line.

After doing this gantry crane to carry the cement blocks we was able to handle it much faster and only 1 worker is required.

check out how we made this in my youtube channel : https://www.youtube.com/c/Goldinton
