Sika provides a wide range of waterproofing solutions, including liquid-applied membranes, sheet membranes, cementitious coatings, and waterproofing admixtures for concrete. These solutions are designed for different applications such as basements, roofs, wet areas, tunnels, and water-retaining structures.
The best system depends on factors such as the type of structure, exposure conditions, and project requirements. Sika offers tailored solutions for residential, commercial, and infrastructure projects, and our experts can recommend the most suitable product based on specific needs.
Waterproofing is essential in construction to protect structures from water ingress, deterioration, and long-term damage. It is necessary in areas where exposure to water or moisture is likely or consistent. These include:
Effective waterproofing in these applications not only preserves the structural integrity of the building but also extends its lifespan, reduces maintenance costs, and enhances safety.
Waterproofing should be integrated during the construction phase—before backfilling, tiling, or plastering. Areas such as foundations, basements, slabs, and wet rooms should be treated early in the building process.
Yes, Sika waterproofing systems are designed for both new builds and refurbishment projects. We provide solutions for repairing existing waterproofing systems, as well as new installations that ensure long-term durability and protection.
Common causes include:
The durability of our waterproofing solutions depends on the product type, application method, and environmental conditions. However, our high-quality materials are engineered for long-term performance, with many systems offering extended lifespans when applied correctly.
Liquid-applied membrane can be applied using brush, roller, or airless spray.
A hot-applied membrane is typically referring to a two-component product that uses a hot spray machine for application. The two-component hot spray machines can be adjusted to a specific mixing ratio, working pressure, and heated temperature.
Not all liquid applied membrane are root resistance. Kindly consult us for suitable root resistant product.
The fibre reinforcement enhances the tensile strength, crack bridging ability and ensures sufficient consumption thickness of the waterproofing coating. The randomly oriented fibres within the mats give maximum multi directional tensile strength to the membranes while allowing them to remain highly elastomeric.
Spray-applied polyurethane/polyurea hybrids, for example Sikalastic®-851, crystalline waterproofing admixtures, or torch-on bitumen membranes are commonly used for below-ground protection.
Wateproofing admixtures are additives mixed directly into concrete or mortar to reduce water permeability. They work by creating a hydrophobic barrier or forming crystals that block micro-pores and capillaries in the concrete.
Sika®-1 is a normal setting liquid waterproofing admixture for mortar and concrete. Sika®-1 blocks the capillaries and pores in the applied cementitious system to provide an effective water barrier against the transmission of liquid water.
Cementitious slurry products, like Sika® Cemflex® or SikaTop® Seal-107 ZA, are used to waterproof basements, foundations, tunnels, retaining walls, brickwalls and other underground structures. The silane systems are used to prevent water penetration of brick and natural stone.
Key types include:
Consider the following factors:
Waterbars are the most common waterproof jointsealing solution for construction joints and are mandatory for expansion joints. The appropriate profile can be chosen from the wide range of Sika Waterbar® based on various materials, depending on project requirements.
Absolutely. For basements, tunnels, lift pits, and water-retaining structures, joint waterproofing is critical. Products like hydrophilic waterbars, injection hoses, or internal joint tapes are often used in these conditions.
Yes. Injection hoses, PU injection, or external joint bandages/tapes can be used for post-construction or remedial joint waterproofing without demolishing structures.
Common reasons include:
Yes. Polyurethane foams are especially effective at sealing actively leaking cracks, as they expand upon contact with water, forming a watertight seal.
They are typically used for:
The most common are:
Rigid (like epoxy): Used for structural crack repairs where movement is not expected.
Flexible (like PU or acrylic gel): Used in dynamic structures or where ongoing movement or water exposure is expected.
Key factors include:
The process typically involves:
When correctly applied with the right material for the condition, injection systems can provide long-term waterproofing and structural stability. Regular inspection may still be needed for high-movement areas.
While mostly used in commercial and industrial applications, PU injection can be used in residential basements or retaining walls, especially where retrofitting is needed.
While both waterproofing and damp proofing are used to protect structures from moisture, they serve different purposes and offer different levels of protection.
Waterproofing stops water, while damp proofing slows or resists moisture. For areas exposed to water pressure or continuous moisture, waterproofing is the more reliable and durable solution.

A bonding agent is a material applied between an existing concrete substrate and a new repair material to improve adhesion between the two surfaces. Bonding agents help create a strong and reliable connection, which is important for the performance and durability of concrete repairs.
A bonding agent can help improve the adhesion between existing concrete and a repair mortar, fresh concrete or other cementitious material. This helps reduce the risk of poor adhesion and supports a durable repair when the substrate has been correctly prepared and the appropriate bonding agent is selected.
Epoxy bonding agents are resin-based products that provide high-strength adhesion and are commonly used for structural bonding applications, including bonding fresh to hardened concrete. SBR bonding agents are synthetic rubber-based products that can be used as bonding agents or added to cementitious mixes to improve adhesion, workability and other performance properties. The appropriate product depends on the substrate, repair material and application requirements.
A corrosion protection slurry is used when steel reinforcement has been exposed during concrete repair and requires protection against further corrosion. The reinforcement should be properly prepared before the corrosion protection coating is applied. Products such as Sika MonoTop®-1010 ZA can also be used as a bonding primer on concrete as part of a complete repair system.
Yes. Some products are designed to perform both functions. For example, SikaTop® Armatec®-110 EpoCem® and Sika MonoTop®-1010 ZA can be used as bonding primers and for reinforcement corrosion protection as part of a concrete repair system.
The correct bonding agent depends on factors such as the condition and type of substrate, the repair material being used, whether the concrete is dry or damp, the required bond strength and the conditions to which the repair will be exposed. Always refer to the relevant Product Data Sheet and recommended Sika repair system to ensure product compatibility and correct application.
Some bonding agents are specifically formulated for use on damp substrates. For example, Sikadur®-32 N is moisture tolerant and suitable for application to dry or damp concrete. Always check the Product Data Sheet for the specific product before application.
Yes. Certain structural bonding agents are specifically designed for this application. Sikadur®-32 N can be used as a structural bonding agent for bonding fresh concrete to hardened concrete, provided the substrate is correctly prepared and the product is applied according to the manufacturer's requirements.
Exposed reinforcement should be fully exposed where required, cleaned back to sound steel, and freed from loose rust, scale, dust, concrete residues, and contaminants. After cleaning, a compatible reinforcement corrosion protection product, such as Sika MonoTop®-1010 or SikaTop® Armatec®-110 EpoCem®, is applied to the steel in accordance with the relevant Product Data Sheet. Once the corrosion protection layer has been correctly applied and is ready to receive the repair material, the concrete repair mortar, such as a suitable Sika MonoTop® repair mortar, can be placed to restore the profile, cover, and protection of the reinforcement.
Reinforcement corrosion occurs when the protective passivation layer around the steel is compromised. This can happen when carbon dioxide causes carbonation of the concrete or when chlorides penetrate the concrete and reach the reinforcement. Moisture and wet/dry cycles can then accelerate the corrosion process.
Corrosion protection helps reduce the risk of deterioration caused by reinforcement corrosion and can help extend the service life of reinforced concrete structures. Selecting the appropriate protection system according to the exposure conditions, concrete quality and extent of corrosion is an important part of a long-term concrete repair and maintenance strategy.
A corrosion inhibitor is a product or system designed to help reduce or control corrosion of steel reinforcement within reinforced concrete. Depending on the system, corrosion inhibitors can work actively to mitigate corrosion or passively by reducing water uptake and the ingress of contaminants such as chlorides.
Active corrosion protection systems are designed to help control or mitigate corrosion of reinforcement. Passive corrosion protection systems, including hydrophobic impregnations, help reduce water uptake and limit the ingress of water-dissolved contaminants such as chlorides. The appropriate solution
depends on the condition of the concrete and the exposure environment.
The correct system depends on the cause of deterioration, exposure conditions, concrete quality, amount of concrete cover and extent of reinforcement corrosion. A suitable assessment of the concrete structure should be carried out before selecting the appropriate repair and corrosion protection strategy.
Concrete repair mortars are specially formulated materials used to repair, restore and replace damaged or deteriorated concrete. They can be used for applications ranging from minor surface repairs to the restoration of spalled and damaged concrete on buildings, bridges, infrastructure and other concrete structures.
Concrete repair mortar is used when existing concrete has been damaged or deteriorated due to factors such as weathering, water ingress, chemical attack, mechanical damage or corrosion of embedded reinforcement. The appropriate repair mortar should be selected according to the type and extent of damage, the substrate and the requirements of the repair.
Repairing damaged or spalled concrete generally involves removing loose or deteriorated concrete, preparing the substrate and treating any exposed reinforcement where required. A suitable concrete repair mortar is then applied to restore the original profile and function of the concrete. The repair system may also include bonding agents, corrosion protection products and levelling mortars, for example Sika MonoTop®-3020 ZA, depending on the condition of the structure.
The appropriate concrete repair mortar depends on the type and extent of damage, the application method, the substrate and the required performance of the repair. Sika offers cement-based, polymer-modified, cementitious and epoxy-based repair mortars for different concrete repair applications. Refer to the relevant Product Data Sheet and recommended repair system when selecting a product.
Yes. Depending on the specific product, Sika concrete repair mortars can be applied manually or by spray application. Some products also allow the consistency to be adjusted to suit the application. Always check the relevant Product Data Sheet for the recommended application method and requirements.

Free-flowing grout is a high-strength grout designed to flow easily into voids, cavities, gaps and recesses without the need for extensive compaction. It provides effective filling and contact around structural elements, helping to achievereliable support and load transfer.
Free-flowing grout is commonly used for applications such as machine and base plates, dowelling reinforcing bars, fixing posts and bedding joints in precast concrete sections. Its flow properties allow it to reach difficult or confined areas while providing high strength and good adhesion to concrete.
Grout is used to fill voids, gaps and cavities and to provide support and load transfer between structural elements. Concrete grouts are commonly used for machine and base plates, anchor bolts, reinforcing bars, precast concrete connections, structural repairs and other applications where high strength and dimensional stability are required.
Non-shrink grout is designed to maintain dimensional stability as it hardens, helping to prevent gaps, settlement and loss of contact between the grout and the surrounding surfaces. This is particularly important where the grout is required to provide reliable bearing and load transfer, such as beneath machinery, base plates and structural elements.
Resin grout may be preferred where high bond strength, chemical resistance, vibration resistance or precise load transfer is required. Cementitious grouts are generally more suited to static or predominantly static loading, while resin grouts may be better suited to demanding applications involving significant vibration, impact or dynamic loading. Resin grout can also be suitable for industrial and structural applications involving heavy machinery, anchor bolts, highway fixings and environments exposed to aggressive chemicals.
Yes. Cementitious grouts can be used for a range of concrete repair and new construction applications, including filling voids, reinstating damaged areas, precast concrete connections, bedding joints and anchoring reinforcement. The appropriate grout should be selected according to the required strength, flow, setting time, application method, loading conditions and service environment..
The appropriate grout depends on the application, required load transfer, loading conditions, substrate, gap size, installation method, environmental conditions and required strength development.
