SikaInject®-216 DE

2-component polyurethane injection resin for permanent waterproofing and structural repair Formerly TPH.® PUR-O-STOP FS-L

SikaInject®-216 DE is a PU-based 2-component, slow-hardening, rigid resin for waterproofing and stabilization works.

  • SikaInject®-216 DE penetrates well into structures to be sealed
  • Viscous and hydrophobic mixture can displace water
  • Adjustable reaction time by adding accelerator (SikaInject® AC 20, see pot-life table)
  • Develops a solid foam at resin-water-interface
  • Application with 1-comp.-pump or 2-comp.-pump

Usage

SikaInject®-216 DE is used for stabilization and consolidation of water-bearing rock, ground, sand as well as for stopping inrushing water in tunnels, shafts, dams and other building structures made from concrete or brickwork. SikaInject®-216 DE can also be used as concrete injection product for force transmitting filling of cracks.  

Advantages

  • SikaInject®-216 DE penetrates well into structures to be sealed

Application steps

SUBSTRATE PREPARATION

Surfaces of cracks, joints and voids need to be clean, free of loose particles, dust, oil and any other bond-breaking substances.

Any dirt must be blown out with compressed air.

MIXING

If 2-component pumps are used the product can be pumped directly from the containers and will be mixed in a static mixer.

Due to the relatively long potlife 1-component pumps can be used, too. Mix components in a dry and clean container until homogeneous appearance (no streaks). Then, mix is ready to be pumped.

When using accelerator SikaInject AC 20, measure the required quantity and pre-mix into part A of the base resin. 

Injection though packers or injection lances.

CLEANING OF TOOLS

Pumps and tools to be cleaned using appropriate cleaner.
