Flexible Embedded Waterproofing Casing

The dimension of the diagram is calculated by millimeter. 

Flexible embedded waterproofing casing applies to the building which requires
decreasing vibration and totally waterproofing at the pipe passing regions. 
Brushing primer over the theca evenly after the sleeve finished (the primer
could be minium or adhesive bitumen primer) and covering antisepticise on request. 

It must be concrete-wall where the sleeve passing through. The range of the fluid 
concrete ought to be 200mm wider than the fins' diameter and the sleeve should be 
concreted tightly inside the wall. 

The thickness of the wall should be no less than 300mm in the sleeve passing range. 
And the minimum diameter of this range should be 200mm large than the fins. 
The weight of the casing material counted by L, the thickness of the wall. 
The casing mainly made from plain steel, and welding by T42.
