Where is waterproofing necessary?

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:

  • Roofs and external walls – to prevent water penetration from rain and environmental exposure.
  • Basements and foundations – to safeguard against ground water seepage and rising damp.
  • Wet areas such as bathrooms, kitchens, and swimming pools – where regular water usage increases the risk of leaks and moisture damage.
  • Balconies and decks – which are directly exposed to rain and weather conditions.
  • Tunnels and bridge decks – to ensure durability and prevent structural compromise due to constant exposure to water and varying environmental conditions.
  • In commercial and industrial environments, waterproofing is also critical in: 
  • Water treatment plants and reservoirs.
  • Plant rooms.
  • And any areas subjected to high volumes of water or continuous moisture.

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.

When should waterproofing be applied during construction?

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.

Are Sika's waterproofing products suitable for both new construction and renovation projects?

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.

What are the benefits of fibre reinforced liquid-applied membranes?

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. 

What is the best waterproofing for underground or substructure applications?

Spray-applied polyurethane/polyurea hybrids, for example Sikalastic®-851, crystalline waterproofing admixtures, or torch-on bitumen membranes are commonly used for below-ground protection.

What are waterproofing admixtures and how do they work?

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.

What admixture can I add to mortar or concrete to make it waterproof?

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.

What waterproofing is suitable for retaining walls?

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.

What types of joints require waterproofing in construction?

Key types include:

  • Construction joints (cold joints between two concrete pours)
  • Expansion or movement joints (accommodate movement due to thermal or structural shifts) 
  • Control joints (placed to control cracking)
  • Pipe penetrations and service entries
How do I choose the right waterproofing system for a joint?

Consider the following factors:

  • Type and location of the joint
  • Expected movement (static or dynamic)
  • Water exposure (submerged, intermittent, or occasional)
  • Chemical exposure or aggressive environments
  • Compatibility with adjacent waterproofing systems
How do I waterproof expansion joints or construction joints?

Can joints be waterproofed after construction is completed?

Yes. Injection hoses, PU injection, or external joint bandages/tapes can be used for post-construction or remedial joint waterproofing without demolishing structures.

What causes joint waterproofing failure?

Common reasons include:

  • Poor surface preparation
  • Incorrect product selection for joint movement
  • Inadequate installation detailing
  • Ageing or UV degradation of exposed materials
  • Movement beyond the product’s flexibility limit
Can injection systems stop active water leaks?

Yes. Polyurethane foams are especially effective at sealing actively leaking cracks, as they expand upon contact with water, forming a watertight seal.

When are injection systems used?

They are typically used for:

  • Sealing cracks in concrete walls and slabs
  • Repairing leaking joints or construction defects
  • Waterproofing basements, tunnels, reservoirs, and lift pits post-construction remediation of water leaks
What types of resins are used in injection systems?

The most common are:

  • Polyurethane (PU) – expands on contact with water to seal leaks
  • Acrylic gels – flexible and long-lasting for sealing joints and porous substrates
  • Epoxy – used for structural crack repair where high strength is required
  • Silicates or cement-based slurries – for curtain injection behind retaining walls
What is the difference between rigid and flexible injection resins?

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.

What factors determine which injection product to use?

Key factors include:

  • Crack width and movement potential
  • Presence of water (active or passive leaks)
  • Structural vs non-structural repair
  • Type of substrate (concrete, masonry, etc.)
  • Environmental exposure (chemicals, temperature, etc.)
How is the injection process carried out?

The process typically involves:

  • Drilling holes at strategic intervals
  • Installing injection packers
  • Injecting resin under pressure
  • Monitoring for proper material flow and seal
Are injection systems permanent?

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.

Is injection waterproofing suitable for residential use?

While mostly used in commercial and industrial applications, PU injection can be used in residential basements or retaining walls, especially where retrofitting is needed.

What are the benefits of injection systems?
  • Non-invasive (no need to excavate or expose structure)
  • Effective for both dry and wet cracks
  • Quick to apply with minimal disruption
  • Long-lasting when correctly specified
Waterproofing vs Damp Proofing. What is the difference?

While both waterproofing and damp proofing are used to protect structures from moisture, they serve different purposes and offer different levels of protection.

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.

How do you protect exposed reinforcement during concrete repair?

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. 

What causes corrosion of reinforcement in concrete?

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.

Why is corrosion protection important for reinforced concrete?

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.

What is a corrosion inhibitor for concrete?

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.

What is the difference between active and passive corrosion protection?

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.

How do I choose the right corrosion protection system for concrete?

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.

A carbonation protective coating is applied to concrete to help reduce the penetration of carbon dioxide into the concrete. This helps protect the alkalinity of the concrete and can reduce the risk of corrosion of embedded steel reinforcement.

How do you protect concrete from chloride ingress?

Concrete can be protected from chloride ingress by applying a suitable protective coating or treatment designed to reduce the penetration of chlorides and moisture. This can help protect embedded reinforcement and reduce the risk of corrosion and further concrete deterioration.

What causes carbonation in concrete?

Carbonation occurs when carbon dioxide from the atmosphere penetrates the concrete and reacts with components within the cement paste. Over time, this can reduce the alkalinity of the concrete and increase the risk of corrosion of embedded steel reinforcement.

What is carbonation in concrete?

Carbonation in concrete is a natural chemical process where carbon dioxide from the air penetrates the concrete and reacts with the cement paste. This reaction gradually reduces the concrete’s alkalinity, which can weaken the natural protective layer around embedded steel reinforcement.
When reinforcement is no longer protected, moisture and oxygen can contribute to steel corrosion, leading to cracking, spalling and deterioration of reinforced concrete structures. Sika concrete protection systems, such as suitable anti-carbonation coatings and protective surface treatments, help reduce carbon dioxide ingress and support the long-term durability of concrete.

How does carbonation affect reinforced concrete?

Carbonation affects reinforced concrete by reducing the natural alkalinity of the concrete around the embedded steel reinforcement.


In sound, highly alkaline concrete, the steel is normally protected by a
passive layer that helps prevent corrosion. As carbon dioxide penetrates the concrete and carbonation progresses, this protective environment can be weakened. If carbonation reaches the level of the reinforcement, and moisture and oxygen are present, the steel can begin to corrode. This corrosion can cause expansion, cracking, spalling and loss of durability in reinforced concrete structures.

Suitable Sika concrete protection systems, including anti-carbonation coatings and protective surface treatments, help reduce carbon dioxide ingress and support longer service life.

How can concrete be protected from carbonation?

Concrete can be protected from carbonation by applying a suitable concrete protection system that helps reduce the penetration of carbon dioxide into the concrete. Anti-carbonation coatings form a protective
barrier on the concrete surface, helping to maintain the concrete’s alkalinity and protect embedded steel reinforcement from corrosion. Good concrete protection also starts with correct surface preparation, repair of damaged or spalled areas, and selection of the right Sika coating or surface treatment for the exposure conditions. Sika anti-carbonation coatings and protective systems help improve durability, reduce carbonation-related deterioration, and extend the service life of reinforced concrete structures.

What are the benefits of epoxy resin flooring?
