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.
