Initial situation<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

This terrace is a walkable roof surface and also serves as the roof of the living space.<\/p>

The surface consisted of ceramic tiles. Over time, the underlying waterproofing lost its integrity, allowing moisture to penetrate into the rooms below.<\/p>

Basically, there were two options:<\/p>

Option 1:<\/strong>
Complete removal of the tiles, renewal of the waterproofing and re-laying \u2013 very time-consuming and expensive.<\/p>

Option 2 (selected):<\/strong>
Sealing directly onto the existing tiles with a high-quality liquid sealant, reinforced by polyester fleece \u2013 without demolition.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Step 1: Apply the first layer of sealant<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

In the first step, the existing tile surface is carefully prepared and coated with the first layer of liquid waterproofing.<\/p>

This layer ensures a uniform base seal and forms the basis for further construction.
Transitions, edges and connections are particularly critical and must be completely covered.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

\n\t\t\t\t\t\t\t\t\t

The polyester fleece is inserted into the still fresh first sealing layer.<\/p>

The fleece is carefully unrolled and pressed down evenly with a roller.,
until it is completely saturated with the sealing material.
This creates a reinforced, particularly tear-resistant sealing layer.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

\n\t\t\t\t\t\t\t\t\t

After embedding the polyester fleece, a second layer of liquid sealant is applied.<\/p>

This layer completely saturates the fleece and covers it entirely.
This creates a homogeneous, seamless and permanently waterproof sealing layer.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

\n\t\t\t\t\t\t\t\t\t

Finally, a special top coating was applied.,
which ensures the long-term protection of the seal.<\/p>

This layer increases resistance to mechanical wear,
UV radiation and weather influences, making the area permanently usable.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Why use 120 g\/m\u00b2 polyester fleece for liquid waterproofing?<\/h2>\t\t\t\t<\/div>\n\t\t

Polyester fleece with a basis weight of 120 g\/m\u00b2<\/strong> offers the optimal combination of flexibility, stability and impregnation capacity for high-quality Liquid waterproofing<\/strong> outdoors.<\/p>

In contrast to conventional nonwovens of the same basis weight, this SA Building Materials Polyester Fleece 120 g\/m\u00b2 additionally sewn with threads<\/strong>.
This stitching increases the Tensile and tear strength<\/strong> clearly and gives the geotextile exceptionally high mechanical strength \u2013 a crucial advantage when Terraces, balconies and roof areas<\/strong>.<\/p>

The sewing process simultaneously creates a targeted perforation<\/strong> the non-woven structure.
This perforation improves the Impregnation with liquid sealants<\/strong>, so that the material is completely embedded and a homogeneous, crack-bridging sealing layer is created.<\/p>

The result is a highly resilient, durable and certified sealing fleece<\/strong>, whose material properties have been confirmed by independent tests (SGS).<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
