No specific Malaysian MS standard; typically specified to manufacturer data sheet or BS EN 15058. Suitable for pedestrian traffic decks, podium planters, green roofs, balconies, and wet areas requiring durable crack-bridging waterproofing.

Waterplug / hydraulic cement is a rapid-hardening Portland cement-based compound used to stop active water leaks through cracks, holes, and penetrations in concrete, masonry, and water-retaining structures in Malaysian construction. The compound is worked into putty consistency and pressed firmly into the leaking point; initial set occurs within 3–5 minutes, cutting off water flow. Slight expansion on set fills cracks and penetrations. Sold in 1 kg and 2 kg tins or bags. Suitable for roof slab penetrations, basement walls, water tanks, and drainage structures. Not for structural repair — intended solely for active leak stopping before a full waterproofing system is applied.

Waterbar / waterstop is a flexible PVC or rubber sealing strip embedded in concrete construction joints to form a continuous waterproof barrier across the joint plane in Malaysian water-retaining and below-grade structures. Available in 5 m, 10 m, and 20 m coils; widths 150–320 mm; profiles include V-profile, flat-web, and dumbbell sections. PVC V-profile waterbars are the most common type in Malaysia, used in water tanks, basements, retaining walls, and swimming pools. The centre bulb accommodates joint movement while flat wings bond to concrete on each side. Often referenced to ASTM C1479 or BS 8102. Profile must match anticipated joint movement.

Silicone / siloxane water repellent (penetrating) is a clear or milky silane, siloxane, or silicone-chemistry treatment absorbed into porous masonry, concrete, fibre cement, or natural stone to impart deep water repellency without altering surface appearance. Penetration depth is 5–20 mm; the hydrophobic lining forms inside pores and pore channels, blocking liquid water while retaining substrate vapour permeability. Applied by brush, roller, or low-pressure spray. Available in 500 g, 1 kg, and 5 kg bottles or pails. Particularly effective on Malaysian parapet walls, external facades, and heritage masonry exposed to windblown monsoon rain and persistent surface moisture.

SBR latex waterproof bonding agent is a styrene-butadiene rubber (SBR) or acrylic latex emulsion used as a cement admixture or priming coat to improve adhesion, flexibility, and water resistance in Malaysian construction waterproofing and screeding work. Used as an admixture, it is blended into cementitious waterproofing slurries and floor screeds; used as a primer, it is applied neat to smooth or low-suction substrates such as old tiles or painted concrete before overlay coats. Improves the water resistance and flexibility of the modified cement system. Available in 1 L, 5 L, and 20 L pails. Not a standalone waterproofer — a bonding and modifying agent within a complete waterproofing system.

Anti-wall cancer / crystalline anti-permeability waterproofing treatment is a specialist product targeting the common Malaysian external wall defect known as 'wall cancer' — the progressive spalling of plaster and concrete driven by carbonation, chloride ingress, or moisture-triggered efflorescence. Products in this category use reactive crystalline chemistry or silicate-based penetrating sealers to block capillary moisture transmission, arrest efflorescence migration, and consolidate the substrate before refinishing. Typically brush-applied to affected external wall areas. Available in 1 kg and 4 kg bottles or pails. Suited for tropical Malaysian climates where persistent humidity and monsoon-driven moisture ingress accelerate wall deterioration. Apply before skim coat and repaint.
