waterproofing-simen

Weberdry WP Slurry is a high-performance, two-component Elastomeric Cementitious (Sluri Simen) coating. Designed for superior crack-bridging and adhesion, it provides a seamless waterproof barrier for concrete substrates in industrial and residential builds.

Product Description

  • Weberdry WP Slurry is a Two-Component Elastomeric Cementitious Coating (Pelapis Kalis Air Elastomerik) engineered for interior and exterior waterproofing systems in Malaysia’s tropical climate.
  • In Malaysia, many waterproofing systems fail prematurely due to high humidity (kelembapan tinggi) and thermal expansion, leading to hairline cracks in RC Gutters and water tanks. For Project Managers and Main Contractors, these leaks lead to expensive remedial works and structural carbonation.
  • Weberdry WP Slurry solves this by creating a flexible, non-toxic barrier that moves with the structure. Its Elastomeric (Kenyal) properties allow for exceptional crack-bridging, ensuring that the substrate remains protected even under minor structural movement. It is optimized for damp substrates, eliminating the “de-bonding” risks common in local construction sites.
  • We maintain consistent stock levels for rapid site delivery to key industrial hubs, including Kuala Lumpur, Selangor, Penang, Johor, and the East Coast.

Key Technical Features

  • Elastomeric Flexibility: High crack-bridging capability ensures integrity during structural settlement.
  • Superior Adhesion: Bonds strongly to damp Concrete (Beton) and Masonry (Batu Bata) surfaces without priming.
  • Non-Toxic & Non-Corrosive: Safe for use in potable Water Tanks (Tangki Air) and sensitive environments.
  • High Humidity Resistance: Formulated to cure effectively in Malaysia’s wet and humid conditions.

Applications & Benefits

  • Commercial (Shopping Malls/Offices): Used in Wet Areas (Bathroom/Kitchen). Benefit: Prevents downward seepage and protects expensive finishes below.
  • Infrastructure (Water Treatment): Potable Water Tanks and Reservoirs. Benefit: Industry-standard compliance for safe water storage.
  • Industrial (Factories): RC Gutters and A/C Ledges. Benefit: Monsoon-ready drainage (Tahan Hujan) and UV resistance.
  • Coastal Grade (East Coast Projects): Protection against concrete carbonation. Benefit: Extends the structural lifespan in salt-mist environments.

FAQ

Question 1: What is the recommended waterproofing for high-humidity RC Gutters in Selangor?

Answer 1: Weberdry WP Slurry is the preferred choice for RC Gutters due to its elastomeric properties that withstand thermal expansion and Malaysia’s heavy monsoon rainfall.

Question 2: Can Weberdry WP Slurry be applied to damp concrete surfaces?

Answer 2: Yes, it is specifically designed for application on dampened substrates, which is ideal for the unpredictable weather conditions on Malaysian construction sites.

Question 3: Is this product suitable for swimming pool waterproofing?

Answer 3: Weberdry WP Slurry provides a robust, seamless membrane under tiles, making it an excellent solution for swimming pools and large water-retaining structures.

Question 4: How many coats of Weberdry WP Slurry are required for water tanks?

Answer 4: For water tanks, a minimum of 3 coats is recommended to ensure the dry film thickness meets industrial durability and hydrostatic pressure standards.

 

Soalan 1: Apakah sistem kalis air yang disyorkan untuk RC Gutter di kawasan lembap seperti Selangor?

Jawapan 1: Weberdry WP Slurry adalah pilihan utama untuk RC Gutter kerana ciri elastomeriknya yang tahan pengembangan haba serta mampu menangani taburan hujan lebat di Malaysia.

Soalan 2: Bolehkah Weberdry WP Slurry disapu pada permukaan konkrit yang lembap?

Jawapan 2: Ya, ia dirumus khas untuk aplikasi pada permukaan lembap (dampened substrates), menjadikannya sangat sesuai untuk tapak projek yang sering terdedah kepada cuaca hujan.

Soalan 3: Adakah produk ini sesuai untuk kalis air kolam renang?

Jawapan 3: Weberdry WP Slurry menghasilkan lapisan membran tanpa sambung (seamless) di bawah jubin, menjadikannya penyelesaian terbaik untuk kolam renang dan struktur takungan air.

Soalan 4: Berapa lapisan Weberdry WP Slurry yang diperlukan untuk tangki air simen?

Jawapan 4: Untuk struktur takungan air, sekurang-kurangnya 3 lapisan disyorkan bagi memastikan ketebalan lapisan memenuhi piawaian ketahanan industri dan tekanan air.
