It is a process of filling the cracks, voids or honeycombs under pressure in concrete or masonry structural members for repairing of cracks, strengthening of damaged concrete or masonry structural members.


Product Description : Sika Injection-101h is a low viscous, fast foaming and solvent-free water-reactive polyurethane injection foam resin, which cures to a dense flexible foam with a fine cellular structure.


  • Sika Injection-101 h is used for the temporary water stopping of high water intrusions in cracks, joints and cavities in concrete, brickwork and natural stonework.
  • To achieve permanent watertight crack sealing, Sika Injection-201 or Sika Injection -203 should be injected subsequently.

Characteristics / Advantages

  • No reaction takes place unless it is in direct contact with water.
  • Sika Injection-101h can be injected as a single component system.
  • The free foaming expansion in contact with water is up to 40 times.
  • The reaction speed (foam formation) is influenced by the temperatures of the mixed material, the structure and the contact water, plus the hydrodynamic conditions.
  • In cold temperatures (< +10oC) Sika Injection-101h can be accelerated using Sika Injection-AC10.

Application Instructions : By single action piston pump operating at high pressure. By twin piston pump when mixed with water (100:15) to produce foams of different densities. Sealing cracks(minimum crack width 0.2mm,for smaller cracks consult Sika technical department) Do not inject Sika Injection-101h solution containing more than 50 % by weight of Sika® Injection-101h as localized high pressure may develop because of excessive foaming & swelling and may damage/ destroy the construction. Drill 15-22 mm holes along the side of the crack at 45° angle. Drill the holes to intersect the crack midway. Install injection packers in the holes and tighten. If the cracks to be injected are 10mm wide or more at the surface, pack open cell polyurethane foam saturated with Sika Injection-101h into the crack. Spray the saturated foam with a small amount of water to activate the grout and create a surface seal. Pump Sika Injection-101h at >20 bar into or behind fissures or into voids which are allowing water to infiltrate into unwanted areas. If voids in concrete being injected contain insufficient moisture to activate the grout inject a small amount of water prior to injecting the grout. Pump Sika Injection-101h for approximately 15 seconds and then pause to allow the material flow into all the cracks and crevices. Keep pumping, watch for material flow and water to appear at the surface or the next packer. When movement stops or Sika Injection-101h appears at the next packer move to the next packer and inject. When sealing vertical cracks start at the bottom and work upward.

Application Method / Tools : Use injection pumps suitable for single part products, such as Sika Injection Pump EL-1, EL-2, Hand-1 or Hand-2.

Cleaning of Tools : Clean all tools and application equipment with Sika Colma Cleaner to remove any polyurethane residue immediately after use. Do not leave Sika Colma Cleaner in the injection pump. Hardened/cured material can only be removed mechanically.

Notes on Application / Limitations The waterproofing process is divided into three phases :

  • Injection -  The time during which the injection material flows under pressure from the pump to the desired moisture/water containing areas.
  • Induction - The time from initial mixing until the reaction starts.
  • Reaction -  The period during which the mix viscosity increases and foam expansion takes place.
  • Sika Injection-101h is generally used for the temporary stopping of high water infiltration. To achieve permanent watertight crack sealing, the subsequent injection of Sika Injection-201/-203 is recommended.
