Weber dry BITU coat — High-Performance Waterproofing Membrane | Pelapis Kalis Air Bitumen

Weberdry BITU coat — High-Performance Waterproofing Membrane | Pelapis Kalis Air Bitumen

A ready-to-use, water-based bituminous coating (Cat Bitumen) designed for superior damp-proofing and structural protection. Ideal for RC gutters, foundations, and retaining walls, offering high-adhesion and seamless moisture resistance.

PRODUCT DESCRIPTION

• weberdry BITU coat is a bituminous waterproofing coating (Pelapis Kalis Air) engineered for sub-structure protection and damp-proofing in Malaysia’s tropical construction environment.
• In heavy industrial and commercial projects, Project Managers often face the challenge of groundwater ingress and concrete carbonation, which leads to structural degradation and costly remedial works. weberdry BITU coat is specifically formulated to mitigate these risks by creating a permanent, seamless moisture vapor barrier.
• The technical superiority lies in its High-Adhesion Formulation, which ensures the membrane remains bonded to the substrate even under hydrostatic pressure. The coating acts as a “Besi Tahan Karat” equivalent for concrete, shielding reinforcement bars from moisture-induced oxidation. For Main Contractors, our logistics network ensures consistent stock availability for site delivery to key hubs including KL, Selangor, and Johor.
• Material Grade: Professional Bituminous Compound
• Application: Sub-structure & Wet Area Waterproofing
• Compatibility: Concrete, Brickwork, and Cementitious Screeds

KEY TECHNICAL FEATURES

• Seamless Membrane: Forms a continuous moisture barrier with no joints, eliminating the risk of lap-joint leakage common in sheet membranes.
• Cold-Applied Safety: Easy application without the need for torches, reducing on-site fire hazards and specialized labor costs.
• High Humidity Resistance: Optimized for the Malaysian climate (Tahan Lembap), maintaining integrity in 90%+ humidity conditions.
• Anti-Corrosive Shield: Protects buried concrete structures from aggressive soil sulfates and groundwater salts.

APPLICATIONS & BENEFITS

• Infrastructure (Retaining Walls): Provides a robust damp-proof membrane (DPM) for Earth Retaining Stabilizing Structures. Benefit: Prevents water seepage through wall joints and protects structural integrity.
• Industrial (Foundations & Footings): Essential for warehouse and factory bases. Benefit: Industry Standard Compliant protection against rising damp.
• Residential (RC Flat Roofs & Gutters): Applied as a multi-coat system for residential drainage and roof areas. Benefit: Cost-effective “Tahan Bocor” solution with rapid application.
• Coastal Areas (East Coast Projects): High chemical resistance against salt-laden groundwater. Benefit: Corrosion Resistance (Tahan Karat) for long-term durability in Terengganu and Pahang sites.

FAQ SECTION

QUERSTION 1: What is the best waterproofing for concrete foundations in Malaysia?

ANSWER 1: weberdry BITU coat is the premier choice for concrete foundations in Malaysia. Its seamless application creates an impenetrable barrier that withstands the high soil moisture levels and hydrostatic pressure common in local tropical terrains.

QUESTION 2: Can weberdry BITU coat be applied to damp surfaces (permukaan lembap)?

ANSWER 2: Yes. It is specifically formulated to adhere effectively to damp substrates. This makes it ideal for maintaining construction schedules during the monsoon season when dry surface windows are limited.

QUESTION 3: How many coats of bituminous paint are needed for retaining walls?

ANSWER 3: For maximum structural protection, Kee Maju Jaya recommends a minimum of two coats of weberdry BITU coat. Applying the second coat at a right angle to the first ensures total coverage and the required membrane thickness for long-term durability.

QUESTION 4: Is weberdry BITU coat suitable for East Coast coastal projects?

ANSWER 4: Absolutely. It features high chemical resistance that provides an effective shield against sulfate-rich soils and saline groundwater, which are prevalent in coastal regions like Kuantan, Terengganu, and Kelantan.

SOALAN 1: Apakah sistem kalis air terbaik untuk struktur asas konkrit (foundation) di Malaysia?

JAWAPAN 1: weberdry BITU coat amat disyorkan untuk struktur asas konkrit kerana aplikasinya yang lancar (seamless) dan keupayaannya menahan tahap kelembapan tanah tinggi yang lazim di Malaysia.

SOALAN 2: Bolehkah weberdry BITU coat digunakan pada permukaan lembap?

JAWAPAN 2: Ya. Ia dirumus khas untuk melekat secara berkesan pada substrat yang lembap. Ini menjadikannya pilihan ideal untuk jadual pembinaan waktu musim tengkujuh di mana peluang untuk permukaan benar-benar kering adalah terhad.

SOALAN 3: Berapakah lapisan cat bitumen yang diperlukan untuk dinding penahan (retaining wall)?

JAWAPAN 3: Untuk perlindungan optimum, Kee Maju Jaya mengesyorkan sekurang-kurangnya dua lapisan weberdry BITU coat. Sapuan lapisan kedua secara bersilang (90 darjah) memastikan liputan menyeluruh dan ketebalan membran yang mencukupi.

SOALAN 4: Adakah weberdry BITU coat sesuai untuk projek di kawasan pantai Pantai Timur?

JAWAPAN 4: Ya, sangat sesuai. Ciri rintangan kimianya memberi perlindungan berkesan terhadap tanah kaya sulfat dan air tanah masin yang sering ditemui di kawasan pesisir pantai seperti Kuantan dan Terengganu.
