Based on the unique waterproofing product portfolio Sika provides you
with the optimized waterproofing solution for your project. In combination with our technical support and onsite solutions a Sika system becomes a real added value for you.
SIKA WATERPROOFING SOLUTIONS BENEFITS
Solution for Basement
Basements and below ground civil engineering structures protected with
Sika waterproofing solutions have increased living comfort and wider
possibilities for use, in addition the total cost of ownership is reduced, and
the durability is increased for the entire service life of the project.
Solution for roof & balconies
Most balconies or roofs are constructed from concrete without any
protection and those substrates will inevitably crack and erode. We have
developed a range of systems specifically designed to protect balconies and
roofs against the challenges presented by the elements.
Solution for Drinking and clean water storage
For drinking water facilities, our waterproofing systems fulfill the
most stringent drinking water approvals and suitable for use in tropical and
hot climatic conditions.
Solution for wet areas
Due to the continual usage of water, waterproofing wet areas like
bathrooms, kitchens, and balconies are essential. it is important to have an
impermeable barrier over the concrete to prevent the spread of moisture. Sika offers specially designed products and systems for all kinds of wet areas and also weak connections and joints.

BITUMEN WATERPROOFING
Bitumen, also known as asphalt, is a sticky, black and highly viscous liquid or semi-solid form of petroleum. Thanks to its waterproofing qualities, it is widely used in construction.

Bituminous membranes are perfect for waterproofing roofs, basements, below-ground structures, bridges and other structures. Once applied, Sika’s bituminous membranes are a thin layer of watertight material fully bonded to the surface. It is a flexible system, able to maintain its waterproof capacity without causing cracks.
PRODUCT RANGE
SikaShield®
SikaShield® is available in a wide range of options to suit many possible systems and designs. Our membranes are made of a selective combination of polymers to achieve better properties, such as cold flexibility, heatresistance, viscosity and softness.
The correct choice of bituminous compound is important to keep the waterproofing function across different temperatures and weather conditions (wind, snow, hail). Therefore, various types of products are offered:

WATERPROOFING MORTARS
Waterproofing mortars are used to protect structures against water infiltration. They are supplied as ready-to-use solutions to seal against damp soil, seepage and percolating water. Waterproofing mortars are often applied in water reservoirs, water retaining structures, basements and other engineering structures as well as beneath tiling for swimming pools, balconies, bathrooms and kitchens.

Sika's two-component waterproofing mortars are advanced solutions for protecting concrete and masonry structures against water penetration. These systems combine a powder (cement-based) and a liquid polymer to deliver excellent adhesion, flexibility, and waterproofing performance.
PRODUCTS
Sika Fast-setting mortar is a specialized construction material designed for rapid hardening and high early strength. It is ideal for time-sensitive repairs and installations, such as patching concrete and fixing cracks particularly where quick setting is required.

WATERPROOFING ADMIXTURES FOR MORTARS
Waterproofing admixtures protect structures from degradation. They increase durability and reduce maintenance costs. Different types of admixtures are used for different parts of a structure namely the roof, basement or walls, as well as for different locations, climatic conditions, and purpose of the structure. Waterproofing admixtures have a broad range of applications in construction and infrastructure development.

LIQUID WATERPROOFING
Liquid-applied membrane (LAM) is a monolithic, fully bonded, liquid-based coating suitable for many waterproofing and roofing applications. The coating cures to form a rubber-like elastomeric waterproof membrane and may be applied over many substrates, including asphalt, bitumen and concrete.

Sika elastic liquid waterproofing coatings are high-performance, flexible solutions designed to protect surfaces against water ingress. These coatings are typically polyurethane- or acrylic-based and form a seamless, durable membrane when applied.
PRODUCTS
JOINT WATERPROOFING
Joint waterproofing refers to the process of making connections or joints in structures impervious to water penetration. It involves applying & installing specialized materials or coatings to seal joints and prevent water ingress, ensuring the integrity ofbuildings and infrastructure.
Commonly used in construction, joint waterproofing safeguards areas where different building components meet, such as expansion joints, construction joints, and pipe penetrations.

Sika elastic waterproof sealing tape is a high-performance, flexible tape designed for sealing and waterproofing joints and cracks in various construction applications.
PRODUCTS
Sika acrylic swellable joint sealant is a high-quality, water-reactive sealant designed to ensure watertight joints in concrete structures. When exposed to water, the sealant expands to fill voids, creating a tight seal that prevents water ingress.
PRODUCTS
Sika PVC joint sealant is a high-performance, flexible sealing solution designed for long-lasting waterproofing in construction joints. It is typically used in the form of PVC waterstops or joint tapes, ensuring a watertight seal in concrete structures.

FAQs
Effective waterproofing prevents water infiltration, which can cause structural damage, deterioration, mold growth, and costly repairs. It also helps extend the lifespan of buildings and infrastructure.
Bathrooms need under-tile waterproofing membranes that are flexible, seamless, and compatible with tile adhesives. Liquid membranes or cementitious systems protect against water ingress into slabs and walls. All corners, joints, drains, and pipe penetrations must be reinforced to prevent hidden leaks. Explore Sika's waterproofing range here.
No. Standard paint cannot prevent water penetration. Waterproofing requires specialized membranes, coatings, or admixtures, such as SikaTop® or SikaProof® systems, which are designed to block moisture and resist structural water pressure.
Yes, but only if the source of the leak is properly identified first. Sika solutions, like liquid-applied membranes or cementitious mortars, can repair and prevent further water penetration in walls, roofs, and wet areas.
Waterproofing can fail due to poor surface preparation, incorrect application thickness, ignored joints or corners, and low-quality materials—so always use professional guidance and Sika-certified products.
Most waterproofing systems require two coats applied at right angles to each other to ensure full coverage and eliminate pinholes. Some high-build or spray-applied membranes may need only one coat if the specified thickness is achieved. Always refer to the Sika's product data sheet for best practices.
Waterproofing powders are commonly integral admixtures added directly to cement or concrete to reduce water absorption. They are cost-effective and widely available. Sikalite® is a typical example, dosed at 1 kg per 50 kg bag of cement, as recommended. Click here for more information.
