Waterproofing
Waterproofing is one of the most critical technical scopes for any modern construction, as it safeguards the building’s longterm integrity against moisture, water, thermal variations and environmental stresses. From horizontal surfaces exposed to ponding water and intense solar radiation to vertical elements facing rainfall, wind and thermal ageing, waterproofing must deliver high durability and longterm stability.
NEOTEX has developed a fully comprehensive portfolio of waterproofing systems, based on advanced coldapplied polyurea and waterbased polyurethane technologies, as well as hybrid, acrylic and cementitious systems for demanding applications. The final system selection must reflect the project’s actual service conditions—substrate, climatic load, use profile and duty level—securing uninterrupted functionality, genuine protection of structural elements and a tangible reduction in future maintenance costs.
Covering the full breadth of waterproofing applications, NEOTEX provides complete systems for flat roofs (including systems with a 25year service life under ETA), for terraces – balconies, for external walls and façades, for swimming pools and fountains, for tanks of every type, for bathrooms – kitchens, as well as for basements and foundation walls.

Flat Roofs
Flat roofs and roof decks are among the most critical parts of any building. Their horizontal geometry favours water accumulation, while exposure to climatic and mechanical stresses makes waterproofing a demanding task. NEOTEX develops specialized systems that provide permanent protection, elasticity and ageing resistance. With strong adhesion to different substrates and the ability to follow microcracking, these systems constitute complete solutions that ensure longterm performance on exposed flat roofs, inverted roofs, in applications of roof waterproofing under tiles, on green roofs, and even rooftop parking decks.
Exposed Flat Roofs
Exposed flat roofs require highperformance waterproofing systems capable of acting as the final surface even without additional protective layers.
Every project has different needs—ranging from nontrafficable roofs to fully functional surfaces subjected to loads or circulation—therefore NEOTEX offers complete flexibility: Flatroof systems with ETA (25year service life), coldapplied polyurea systems for maximum durability, waterbased polyurethane systems for high elasticity and resistance to ponding water, hybrid waterbased systems for longterm UV stability, acrylic systems for increased vapour permeability, and cementitious waterproofing systems for areas subject to possible hydrostatic pressures. In this way, each roof can be equipped with the most suitably tailored system, ensuring longterm waterproofing, a stable aesthetic appearance and performance that truly responds to the project’s demands.
Inverted Roofs
In inverted roofs, the waterproofing layer lies beneath the thermal insulation, requiring systems resistant to permanent moisture, limited ventilation, and pressure from the layers above. NEOTEX solutions—using cementitious waterproofing systems, coldapplied polyurea systems, and waterbased polyurethane systems—ensure complete protection of the concrete and longterm functionality of the structure.
Waterproofing under Tiles
Waterproofing under tiles on flat roofs and roof decks requires appropriate systems to ensure absolute protection against moisture and leaks. Systems must provide elasticity and resistance to temperature variations, absorbing substrate micromovements without cracking. The durability of the waterproofing is critical, since even a minor failure at joints or bonding allows water to infiltrate beneath the tiles—where it becomes trapped—potentially causing blistering, debonding and, ultimately, ingress into the building, damp, mould and costly repairs; precise leak detection in such cases is typically very difficult.

Rooftop Parking Decks
Openair parking areas located on roof decks and flat roofs require specialized, highstrength systems, as these surfaces are subjected to far greater mechanical and environmental stresses than typical roofs. The systems must combine robust waterproofing with reliable wear protection, offering excellent elasticity, controlled slip resistance and resistance to temperature variations, while maintaining integrity despite thermal movements and substrate micromovements.
They must also withstand intense abrasion, point loads, vehicular traffic and chemical exposure such as oils, fuels and salts. Selecting robust, certified waterproofing systems with high resistance to vehicular traffic is critical to ensure the longterm protection of the structure.
Green Roofs
Green roofs require waterproofing systems with high resistance to root penetration, permanent moisture and continuous water load. The waterproofing must ensure absolute watertightness and longterm stability, maintaining elasticity despite temperature variations and substrate micromovements. NEOTEX provides specialized coldapplied polyurea solutions that ensure effective waterproofing, root protection and longterm functionality of the green roof.
Balconies – Terraces
Balconies and terraces are technically sensitive zones, combining intense solar exposure, stagnant water and frequent thermal movements. Failures often appear as debonding, efflorescence and substrate damage, as well as moisture ingress indoors – especially at corners, joints and parapet interfaces. NEOTEX treats these areas not as “small roofs” but as distinct technical zones with their own systemselection criteria.
Accordingly, NEOTEX systems for balconies and terraces focus on high elasticity, robust adhesion, resistance to permanent moisture and to cracking, as well as UV stability where required. Whether for hightraffic exposed terraces-balconies where the waterproofing is the final wearing surface or for undertile waterproofing, NEOTEX delivers solutions tailored to the actual use, substrate and climatic conditions of the project, ensuring stability and longterm protection.
Terraces – Balconies with High Traffic
Terraces and balconies are subjected to intense mechanical loading, circulation, abrasion and frequent washing. NEOTEX exposed waterproofing systems for hightraffic balconies/terraces are based on advanced coldapplied polyurea technologies and provide high elasticity, mechanical durability, slip resistance and UV stability, maintaining watertightness even under continuous temperature and load variations.
Waterproofing under Tiles
Waterproofing beneath tiles on balconies – terraces requires appropriate systems to ensure absolute protection against moisture and leaks. Systems must provide elasticity and resistance to temperature variations, absorbing substrate micromovements without cracking. Durability is critical: even a minor failure at joints or bonding allows water to infiltrate beneath the tiles—where it becomes trapped—leading to blistering, debonding and, ultimately, ingress into the building, damp, mould and costly repairs; precise leak detection in such cases is typically very difficult.
NEOTEX solutions—using cementitious waterproofing systems, coldapplied polyurea systems and waterbased polyurethane systems—ensure complete protection against moisture ingress and the longterm functionality of the structure.
External Walls – Façades
External walls and façades form a building’s first line of defence against moisture, wind and thermal stresses. The appearance of hairline cracks, rainwater absorption and thermal ageing of the substrate can lead to render degradation, salt efflorescence and loss of thermal performance. NEOTEX treats the façade as a critical technical element, not merely an architectural shell.
NEOTEX façade systems deliver elasticity, waterproofing, breathability, crack stabilisation and protection against solar radiation, offering solutions for numerous substrates—whether aged renders or exposed concrete—thus ensuring longterm durability and aesthetic stability of the building.

Swimming Pools - Fountains
Swimming pools and fountains are zones of constant loading, where the waterproofing & protection system is continuously exposed to hydrostatic pressures and remains permanently immersed in water and treatment chemicals such as chlorine, salts and biocides. The substrate is subjected to constant pressure and, in many cases, intense osmotic forces, which may lead to blistering, delamination, coating degradation and leaks, or to moisture ingress into adjacent structural elements. For this reason, the correct selection of the waterproofing and protection system is critical to the functionality, safety and long term durability of the construction.
NEOTEX provides complete waterproofing and protection systems for pools and fountains, designed to withstand continuous positive and negative hydrostatic pressures, chemical exposure, thermal variations and substrate movements, ensuring excellent adhesion, flexibility and longterm, reliable performance of the installation
Tanks
Tanks—whether for potable water, wastewater treatment (biological treatment) or chemicals—are environments with clearly elevated technical requirements. The selected waterproofing & protection system must ensure complete watertightness, resistance to hydrostatic pressures and chemical stability.
NEOTEX offers specialized systems tailored to the contents of each tank. These solutions protect the concrete, eliminate leaks and provide excellent resistance to chemical attack and continuous moisture.

Bathrooms – Kitchens
Bathrooms and kitchens are interior zones with increased waterproofing demands due to the continuous presence of moisture, water vapour, thermal variations and frequent water use. The presence of plumbing, services and tiling creates a complex technical reality: the waterproofing must resist capillary ingress and bond fully to the substrate without trapping moisture. NEOTEX addresses these spaces with dedicated undertile waterproofing systems acting as a stable “protection infrastructure” beneath the final finishes, preventing future failures, mould and damage to adjacent areas.
Waterproofing under Tiles
Undertile waterproofing in highhumidity rooms such as bathrooms and kitchens requires appropriate systems to ensure absolute protection against water ingress and leaks. Systems must provide crack bridging and resistance to temperature variations, absorbing substrate micromovements without cracking. Durability is critical: even minor failures at joints or bonding allow water to penetrate beneath the tiles—where it becomes trapped—causing blistering, delamination, mould and damage to neighbouring rooms.
NEOTEX solutions—using cementitious waterproofing systems, coldapplied polyurea systems and waterbased polyurethane systems—ensure complete protection against moisture ingress and the long term functionality of these areas.
Basements – Foundation Walls
Basements and foundation walls are among the most demanding waterproofing zones, often subjected to permanent hydrostatic pressure, water ingress, salts and high soil moisture. The lack of ventilation and the constant presence of moisture make any failure especially critical, as it can affect structural integrity, thermal insulation and indoor hygiene.
NEOTEX offers permanent solutions with multi-layer cementitious waterproofing systems that act both at the surface and in depth (crystalline action), creating a continuous, watertight barrier that prevents water ingress even through micro cracks. Applicable to new builds and remediation works, NEOTEX ensures basements remain dry, clean and protected against damage, salts, mould and persistent positive and negative pressures.
