Positive/Negative Side Crystalline Waterproofing Solutions

Wet or damp basement floors cannot be used as comfortable living spaces and they reduce the life and value of the building.

The best solution is to perform external waterproofing of the parts of the buildings that will remain under the ground during the construction phase of the building. In cases where external insulation is not made, it is possible to tolerate this situation and to insulate from inside to provide the necessary waterproofing.


Surface Preparation

The application surface should be checked before waterproofing. The surface should be clean, smooth and sound. It is necessary to clean loose particles, residues that will prevent adhesion and penetration of the product into the concrete, such as dust, dirt, oil, soil, on the concrete surface where crystalized waterproofing materials give high performance, thoroughly by using water jet, sand blasting or wire brush. Defective applications such as cracks, capillary cracks and segregation on the concrete surface should be opened by breaking and cleaned and 3032 Izoseal 2K+ should be applied to the cleaned areas, followed by the rectification phase by using 4002 Tamirart 30 thick repair mortar or 4004 Tamirart S40 structural repair mortar. The surface should be saturated with water before proceeding with waterproofing application. It should be noted that the surface is not wet but humid during the application.


Waterproofing

3032 Izoseal 2K+ two component crystallized waterproofing and protection mortar should be applied on the concrete surface with brush or roller as 2 or 3 layers. 3032 Izoseal 2K+, when applied to concrete surface, penetrates through the cavities into the concrete and active chemicals in its formula react with free lime and moisture in the capillary cavities of concrete and form insoluble crystal structures. These crystals fill the cavities and shrinkage cracks in the concrete to prevent the passage of water and make the concrete resistant to water pressure from inside and outside. It eliminates surface leaks and moisture.


Finishing Application

Entire surface should be coated with 4041 Ince Sıva (Finish Plaster) in order to level the surface and make it ready for the next application following the waterproofing application in order to convert the basement floors into lively, joyful, colourful, healthy and comfortable living areas. Macunart white cement based fine surface preparation putty in white colour, formulated with special binders and chemicals to eliminate surface defects in exterior and interior surfaces is applied on 4041 Ince Sıva (Finish Plaster) in order to get a surface ready for painting. Macunart, which is a surface levelling and filler mortar, with high stability, reduces the paint consumption because of it low absorbency, does not cause much dust during sanding and does not prevent the walls from breathing. It creates a healthy and breathing living area with Kale Isıtut acrylic based interior finish paint, which has the dullness resembling velvet texture by reducing the thermal loss on wall surface up to 4 times by making thermal insulation effect thanks to micro glass beads in its formula.
