LEAKING CONCRETE STRUCTURES BELOW GROUND, such as basements and civil engineering structures, can have greatly reduced service life due to steel corrosion and concrete damage, in addition to any reduced functionality and use. In order to avoid the expensive costs of repairs to the structure, or to water damaged interior finishings, furnishings or o...
There are three primary success factors involved in ensuring the efectiveness and durability of injection works. It is essential that the right combination of injection materials, injection equipment, and injection method are selected and this is what Sika’s extensive technical and practical experience provides: Equipment Material Successful Inject...
The selection of the right injection material and the right specific injection product for the defined project requirements is the first key factor for success. This especially means the materials’ viscosity, flexibility, and behavior in contact with water, all of which can significantly influence the efectiveness of the injection.
Appropriate equipment for the selected injection material, including for the correct preparation, mixing, and delivery of the material, is the second key success factor. This means everything from the initial dosage and mixing, delivery from a suitable pump, to the use of the right packers/ports/ connectors.
Third, the correct injection method and application techniques must be used by trained, competent, and experienced contractors in order to ensure the success and provide complete and permanent leak sealing solutions.
Sika is a ‘full range’ supplier, meaning that Sika not only has the full range of alternative injection technologies and materials, but we are also the world’s leading supplier of engineered waterproofing, concrete repair, and protection solutions in order to prevent or seal and waterproof any type of leak in your structure - from the basement to t...
Sika’s injection solutions are tested and approved to the leading global standards to provide safe and reliable injection solutions.
Sika provides advice and support from the design ofice through to completion of the injection and any associated works on site. This expert technical advice and practical assistance is to help ensure the selection and installation of the right injection materials, equipment, and application methods.
We understand that, on many projects, it will be preferable to use an experienced Specialist Contractor for injection works to seal any leaks that occur. On others, for diferent practical and logistic reasons, it will be better to train teams from the main contractor to do the work. This is why Sika provides unrivaled technical and practical traini...
All around the world, there are experienced Sika professionals to provide technical support exactly where it is required - in your ofice or on-site.
Polyurethane foaming resins are designed to expand with water to block the passage of water through the crack or void. Their fast expansive reaction with water forms a tough and flexible/elastic foam. For permanent waterproofing, these polyurethane foaming resins are re-injected with a suitable acrylate injection resin.
Acrylate resins are hydrophilic, very flexible, and used for non-structural injections of cracks, joints, and voids, including for injection hose systems, compartment systems, and area (e.g., Grid and Curtain) injection works. For application, Acrylate resins have an extremely low viscosity (similar to water) and therefore have ideal penetration ab...
Epoxy resins have relatively high tensile and compressive strengths in relation to concrete, they are generally regarded as ‘rigid’ materials and widely used for structural repairs by injections of cracks and voids in load bearing reinforced concrete structures or elements. Their low viscosity allows excellent penetration into cracks in the structu...

The storage container of the pump is filled with the pre-mixed resin or microfine cement grout. The pot-life of this injection material starts after mixing and it is always necessary to apply the complete mixed volume within the relevant pot-life. There are hand, piston, and diaphragm pumps available using 1- pump technologies and they are designed...
These have two storage containers, each of which is filled separately with a diferent component. The components only come together when they are pumped through the static mixer, therefore, the pot-life starts in the static mixer. Due to this, this kind of pump can be used for very fast reacting resin based materials. There are 2-component pumps des...
Single component pumps are the universal injection pumps and are suitable for a wide range of applications. They are ideal for professional crack sealing applications and for the injection of SikaFuko® hoses and membrane compartment systems.
Vacuum pumping equipment is important for re-injection of the SikaFuko® Injection hose systems. It is used for flushing and cleaning the SikaFuko® hoses with water after injection with acrylate gel or microfine cement materials to enable the system to be used for future re-injection, if required.
Two component pumps are designed for curtain injection behind the structure, for high volumes, or using fast reacting polyacrylate gel resins.
Sika® Injection Packers, or Ports, are fixed into or onto the structure and are used as nozzles to connect the injection pump to the structure and direct the material to fill the cracks or voids. Sika® Connection Packers are used to connect embedded injection hoses or compartment systems.

CRACKS IN CONCRETE STRUCTURES can be caused as the result of excessive load or stress on the structure by internal or external forces (e.g. ground movement). Leaking cracks need to be closed and sealed to secure the watertightness and durability of the structure.
SikaFuko® INJECTION HOSE SYSTEM is used on its own for construction joint sealing, or as a back-up system in combination with waterstops. Installation is done during the concreting phases of the project.
Locate the start and of injection hose in end the ected construction joint, e.g., in junction boxes. Connect the pump to the injection hose system, e.g., through Sika® Packer tong.
BASEMENTS CAN DEVELOP LEAKS over large sections of their whole area for many reasons including inadequate concrete mix design, placing, or compaction, in addition to ground movement and rising water tables, etc. These larger areas can be sealed by curtain injection behind the concrete structure.
