Application

Koster Injection Systems can be used to seal any type of water ingress into a below ground structure. Typical applications include:

  • Lift Pits.
  • Plant Rooms.
  • Bio gas chambers.
  • Basements.
  • Bridges and arches.
  • Reservoirs.
  • Pile heads and caps.
  • Steel sheet piling.
  • Underground car parks.
  • Injection into any solid building medium such as Concrete, Block, Brick, etc.

Description

Koster manufacture a range of resins for treating issues with water penetrating through structures below ground. Depending on the type of substrate, soil type and type of water ingress, a robust injection system can be proposed.

Please note, every injection system should be unique to the particular project. A designed approach should be taken to ensure remedial success. The Koster technical team can offer design and site support.


In the case of water actively leaking or weeping from a crack/honeycombing or construction joint, Koster 2 IN 1 can be used. This is a twin injection material, Upon first injection the resin will foam on contact with water and temporarily stop the ingress. Once the material is then re-injected into the dry crack, the Koster 2 IN 1 will encompass the foam in an elastic solid body resin thus sealing permanently allowing for continued minute crack movement. This two-stage injection process with only one resin is unique to Koster and has a long track record of successful UK projects.


In cases of very rapid water ingress Koster IN8 is used. This is a fast foaming PU injection resin which will create a permanent elastic seal. It works best in cases where large voids are anticipated in the ground behind the structure.


Both the Koster 2 IN 1 and Koster IN 8 injection resins are installed using the Koster 1C Injection Pump via injection valves called 'Koster Superpackers' into the crack. Depending on the application, different packers are available.


It is important to note that only trained and approved persons should carry out these types of injection works. Koster have a large database of approved contractors who they can offer.


System Components:


  • Koster 1C Injection Pump.
  • Koster Superpackers.
  • Koster 2 IN 1.
  • Koster IN 8.
  • Koster PUR Cleaner.

Packers

Koster One-Day-Site Packer.

Guidance for specification option:

  • Allows injection works to be completed in one day. Immediately after injecting, the part of the port which protrudes from the wall can be unscrewed and removed.
  • The front part of the port stays in the wall sealing the borehole so that no injection material can flow out of the borehole even under high pressure.
  • The borehole can thus be closed immediately after the injection is carried out.

Koster Superpacker.

Guidance for specification option:

  • With firmly mounted cone-head (grease nipple) or pan-head fittings for pressure injection, galvanized.
  • KÖSTER Superpackers are suitable for pressure injection.
  • They are inserted into the borehole so that the rubber seal of the port is completely submerged in the borehole.
  • Then, the port is tightened meaning the rubber seal is compressed which causes it to expand in width thus pressing it onto the wall of the borehole.
  • The cone shaped tightening piece also ensures that the seal is pressed tightly onto the wall of the borehole.

Injection resin

Koster 2 IN 1 Injection Resin.

Guidance for specification option:

  • Will cure with or without water, solvent-free, polyurethane injection resin.
  • The one product is used as an injection foam in water bearing cracks and joints as well as a flexible solid-body resin for permanent crack sealing where no water is present.
  • KÖSTER 2 IN 1 can therefore be used at both stages of a typical 2 stage injection process, and is also ideal for situations where it is not clear how wet the crack may be.
