Our materials and systems are there where you need them most every day, everywhere. From high rise buildings and bridges to your house renovation, from tunnels to wind turbines, and all that is in between.
Protecting Every Room From The Ground Up
A truly protected home needs more than just a coat of paint; it needs a seamless, integrated waterproofing system for every single wet area. Traditional construction practices often leave critical gaps, allowing moisture to travel through concrete, grout, and cracks. Sika treats the root cause of the dampness, not just the surface stain, using advanced waterproofing solution and professional crack sealing systems.
Tile Joint Seepage: Creating A Sanctuary That Stays Perfectly Fresh
Bathrooms are the highest-moisture zone in your home. Water constantly attacks the floor, shower walls, and tile joints. Without a proper bathroom waterproofing system, water seeps through, causing tile joint seepage, bathroom leakage, damaging the room below, and breeding microbes in the grout. Our bathroom waterproofing system creates a tank-like, seamless barrier underneath your beautiful tiles, ensuring your personal sanctuary remains spotless and dry with reliable shower waterproofing. Our bathroom wall waterproofing protection further seals the moisture in the bathroom space without affecting adjacent spaces.
Mold And Fungus: Shielding the Heart Of Your Home
Constant splashing around the sink, washing machine overflows, and wet mopping make kitchen and utility zones prone to dampness that breeds and spreads mold and fungus to adjoining living areas. Waterproofing chemical here also stops moisture from soaking into the walls and ruining your expensive modular cabinetry, protecting the heart of your home from unseen damage. Our systems also include durable waterproof floor coating solutions for wet utility spaces.
Damp Walls: Breathing Life Back Into Your Living Spaces
Damp patches spreading upwards on interior walls are often a sign of rising damp or a leak from an adjacent bathroom. Painting over it is a temporary fix that will fail. Our solutions act as a damp-proof course and a wall dampness solution, ensuring your painted surfaces stay flawless and your family breathes clean air, free from mold and fungus triggers. They also work as an effective wall seepage solution, helping control hidden water seepage in wall surfaces. Through Sika’s advanced internal wall waterproofing and waterproofing walls interior systems you can eliminate wall dampness.
Water Tanks: Securing Every Last Drop Without A Leak
Overhead and underground tanks are lifelines that are often forgotten until a water tank leakage appears on the walls below. Sika’s potable-water-safe coatings ensure you are not only stopping leaks but also keeping your stored water safe, clean, and contamination-free, preventing structural damage to your foundation and walls through advanced foundation waterproofing systems for tank floors and durable waterproof sealant protection for the joints and gaps.

Indoor Waterproofing Technology Explained
Liquid Applied Waterproofing
The waterproof coating is a seamless, stretchy “elastomeric skin” that cures to a flexible, rubber-like membrane. Perfect for high-movement areas like bathrooms and balconies, it handles structural shifts without cracking while maintaining a durable and seamless layer.
Cementitious Waterproofing
A rigid, mineral-based barrier that chemically bonds with concrete surfaces. It’s the go-to for water tanks and internal walls due to its excellent adhesion, allowing for direct tiling or plastering with a durable, waterproof glue finish.
Polymer-Based Waterproofing
Standard mortars are made tougher by blending them with advanced polymer fortifiers, making them less porous. This creates a high-strength, highly adhesive waterproofing screed for repairing and levelling floors before the final membrane.
Crack & Joint Treatment
Movement is the enemy of waterproofing. This involves cleaning joints and shifting cracks, filling them with a flexible joint sealant, and bridging them with a bandage system to create a permanently moving, watertight union.
Integral Waterproofing Compound
Protection built into the very structure. By adding these to the concrete or plaster mix during construction, you create a water-repellent mass from the inside out, with no exposed membrane to damage.
