Sloping
Sloping and flooring are not separate from the insulation and sealing layer, as well as the reinforcement of the structure. Each of these cases is completely interrelated with others and acts as the foundation of the next layer.
This means that we need to be knowledgeable enough of insulation, sealing and strengthening if we want to create a resistant surface against water, moisture, all detergents, atmospheric agents, algae, moss, bacteria, etc with good slope once for always.
Based on the NSG Co. procedure, insulation starts from the first layer of the concrete surface. The concrete floor surface of lavatories, bathrooms, kitchens, roofs, roof gardens, courtyards, terraces, balconies, etc. is the first place that needs to be insulated completely because water and moisture should not intrude to the ceiling of the lower stories under any conditions. Therefore, piping should be done and the concrete surface must be sealed with NSG-Z90 before pouring pumice, sloping and aligning the contour line. Then it is time to provide the next layers.
The mortar for sloping or contour lines must be highly resistant because it is a separator between the selected parts of the contour line and should be more resistant than other layers and therefore should not never be settled or destructed. That is why NSG-N50 should be applied in making the sloping and contour line mortar.
Lightening and reducing the dead load on the roof is one of the most important issues in controlling earthquake shocks and preventing structural settlement. So, mineral/industrial pumice is one of the best materials for creating a floor slope and filling the extra space.
