Now, we start with Civil work first- start building columns(iron bars-saria and concrete cement mixture) of all the covered structure with sizes( 1″1/2, 1″ ) or depend upon the area and height which thekedar suggests.Meanwhile, fabricator starts measuring and panning structure design and start placing iron channels on columns.These works can happen simulatenously and both(civil enginer and fabricator) presence required, as this the main part and coordination work is required in between them.
And, after finishing columns civil engineer would start creating walls – you can use either bricks or AAC blocks. Now, hope fabricator would be busy in structuring of shed with Iron pipes and channels over the covered area.And started installing water gutter (Patnalla in Hindi – where rainwater would be flown in raining) along two sides where water would be flown.
Now, things to remember next – for rain water which would fall over the shed either you use chambers below the surface of the floor or only water gutter.If you have small area of warehouse less then 10,000 Sqft you can use only water gutter no need of creating chambers(for flowing water) , and in case of greater than 10,000 Sqft area I would suggest you must use chambers(it just 4*3*5 ft chamber) on particular distance(20 ft depends upon the area).And start installing chambers though civil workers and connect these to each other.So that, the water would be flown outside without any blockage and leakage.And these chambers would be connected to water gutters(patnala) from above.This will increase patnalas life and prevent warehouse leakage of water from above in case of heavy raining.
And , meanwhile fabricator would resume to installing sheets over the roof and sidewalls. And civilengineer or thekedar would start filling the surface area inside warehouse with these things:-
- Debris( Malba )
The debris would be dumbed to a certain height so that, sand could be thrown scattered properly covering all the area upto 1-2 feet.And then start flowing water over the sand surface over of few days so that sand could be set properly and hard enough.And then start, running roller machine for many time for smoothing of sand surface. When you confirmed that the surface is tough and set hard you can start covering the surface with hard stone (2-3 inches size).And then run roller machine again to set the surface hard.
And after then, start tying steel/iron tying rebars over the whole surface. And doing pv plaster of floor with cement, crusher and stone mixture in portionwise . After setting particular portion in 5-6 hours, the floor is hard setted with with hardener spread and running tremix machine over it for smoothness and hardening.And pour water over the floor for a couple of days, sothat the floor could soak away the water and become hard.Water soaking is a must in flooring, after that go for the grouping() part which reduces stretch/break marks on the floor.
The floor is finished, but for extra hardening and shinning flooring is required.As if you didn’t do floor finishing/polishing the floor would break after sometime and got ruffed .And stone will be showing after sometime, to get rid of these issues – use floor polishing treatment.It will give shine, smoothness and durability to floor and prevent from breaking.
