Weberdry FLEXI-coat — High-Flexibility Cementitious Waterproofing | Pelapis Kalis Air Fleksibel

Weberdry FLEXI-coat — High-Flexibility Cementitious Waterproofing | Pelapis Kalis Air Fleksibel

A premium, two-component flexible waterproofing membrane reinforced with polymer. Designed to bridge hairline cracks and provide a seamless barrier for water-retaining structures. Ideal for high-movement zones.

PRODUCT DESCRIPTION (Technical Authority) Weberdry FLEXI-coat is a high-performance cementitious waterproofing (kalis air) system engineered for long-term structural protection in high-humidity Malaysian environments.

The Project Challenge: Modern high-rise developments and water-retaining structures often face hairline cracks due to thermal expansion and structural settling. For Project Managers and Main Contractors, these cracks lead to devastating leaks (kebocoran) and concrete carbonation, especially in monsoon-prone regions.

The Technical Solution: Weberdry FLEXI-coat utilizes a Fiber-Reinforced (Gentian Diperkukuh) polymer-modified formula that creates a breathable yet impermeable membrane. Its elastic properties allow it to bridge cracks up to 1mm, ensuring structural integrity even under hydrostatic pressure. Unlike rigid systems, this “Flexi-membrane” moves with the building, preventing debonding.

Logistics & Availability: We maintain consistent stock levels for rapid site delivery to key industrial hubs, including Kuala Lumpur, Selangor, Johor, and the East Coast.

Quick Specs:

Material Grade: Polymer-Modified Cementitious (High-Flex)

Application: Wet areas, Water Tanks, Balconies

Compatibility: Concrete, Render, and Brickwork

KEY TECHNICAL FEATURES
✓ Crack Bridging (Tahan Retak): Engineered to bridge active hairline cracks, preventing water ingress in high-movement structural zones.

✓ Fiber-Reinforced Integrity: Embedded fibers provide superior tensile strength, ensuring the membrane does not tear under heavy hydrostatic pressure.

✓ Potable Water Certified: Chemically stable and safe for use in water tanks and reservoirs without leaching contaminants.

✓ Excellent Adhesion: Bonds seamlessly to damp substrates, reducing downtime in Malaysia’s unpredictable weather.

APPLICATIONS & BENEFITS
Residential (High-Rise Bathrooms): High flexibility ensures no leaks even with floor vibration. Benefit: Reduced maintenance complaints and long-term waterproofing warranty.

Infrastructure (Water Tanks/RC Tanks): Certified for water-retaining structures. Benefit: Industrial Standard Compliant for municipal and commercial utility projects.

Coastal Grade (East Coast Resorts): Resistant to chloride ion penetration and high humidity. Benefit: Superior corrosion protection for reinforced concrete near saline environments.

Commercial (Swimming Pools/Podiums): Provides a seamless barrier under tiles. Benefit: Protects structural slabs from expensive water damage and efflorescence.

ENGLISH
Q1: What is the best waterproofing for concrete water tanks in Malaysia? A1: Weberdry FLEXI-coat is the premier professional solution. It is a fiber-reinforced cementitious system specifically engineered to withstand hydrostatic pressure and structural movement common in Malaysian RC water tanks, ensuring a permanent, leak-proof seal.

Q2: Can Weberdry FLEXI-coat bridge existing hairline cracks? A2: Yes. This system is formulated with high elasticity to bridge active hairline cracks up to 1.0mm. This is critical for local projects where thermal expansion (due to high heat) often causes rigid, non-flexible waterproofing to fail.

Q3: Is Weberdry FLEXI-coat suitable for coastal projects in Terengganu or Pahang? A3: Absolutely. Its “Coastal Grade” formulation provides superior resistance to high humidity and protects concrete structures against chloride attacks, making it the ideal choice for East Coast infrastructure and beachfront developments.

Q4: Why choose Weberdry FLEXI-coat over traditional bitumen? A4: Unlike bitumen, FLEXI-coat is a polymer-modified cementitious system that offers superior adhesion to damp concrete. It is non-toxic, safe for potable water, and allows for direct tiling, making it more efficient for high-spec bathroom and reservoir projects.

S1: Apakah sistem kalis air terbaik untuk tangki air konkrit di Malaysia? J1: Weberdry FLEXI-coat adalah penyelesaian profesional utama. Ia merupakan sistem simen diperkukuh gentian (fiber-reinforced) yang direka khas untuk menahan tekanan hidrostatik dan pergerakan struktur pada tangki air RC, sekaligus menjamin lapisan kalis bocor yang kekal.

S2: Bolehkah Weberdry FLEXI-coat menutup kesan retak halus (hairline cracks) yang sedia ada? J2: Ya. Sistem ini dirumus dengan elastisiti tinggi untuk merapatkan retakan halus aktif sehingga 1.0mm. Ciri ini sangat kritikal bagi projek di Malaysia di mana pengembangan haba akibat cuaca panas sering menyebabkan sistem kalis air jenis keras (rigid) pecah dan gagal.

S3: Adakah Weberdry FLEXI-coat sesuai untuk projek pesisir pantai di Terengganu atau Pahang? J3: Sudah tentu. Formulasi “Gred Pesisir Pantai” ini memberikan rintangan tinggi terhadap kelembapan melampau dan melindungi struktur konkrit daripada serangan klorida, menjadikannya pilihan ideal untuk infrastruktur dan pembangunan di Pantai Timur.

S4: Mengapa perlu memilih Weberdry FLEXI-coat berbanding bitumen tradisional? J4: Berbeza dengan bitumen, FLEXI-coat adalah sistem simen ubah suai polimer yang menawarkan daya lekatan lebih kuat pada konkrit lembap. Ia tidak toksik, selamat untuk air minuman, dan boleh dipasang jubin secara terus, menjadikannya lebih cekap untuk projek bilik air dan takungan air spec tinggi.
