Sika Parex Railfast Grout

SIK10127
SIK10127

A polyester resin based material used for grouting where rapid early strength development is required. Railfast Grout can be used at section depths between 10mm and 25mm without the aggregate component, or for section depths between 25mm and 75mm with the aggregate component. Its uses include:

  • Grout pads under rail base plates
  • Filling of grout feeder boxes in steel support placement
  • Fixing bolts, starter bars, tieback anchors, dowels, etc
  • Installing lighting units, barriers, ground anchors, fences, etc
  • Frame support
  • May only be used by experienced professionals

Description

Parex Railfast Grout is supplied as a two pack system ready for onsite mixing consisting of two tins of base resin, two bags of catalysed filler and one bag of aggregate. The mixed grout will harden to give rapid strength gain reaching 50N/mm² in 2 hours allowing rapid return to service.

Features & Benefits


  • Winter and Summer grades available
  • Very high early strength gain
  • Ready-to-mix, pre-batched units for consistency and quality
  • Non-shrink
  • Resistant to petroleum products and road salts
  • Resistance to vibration
  • Wide range of application depths



Important Considerations


  • Minimum substrate temperature 5°C
  • The material must be conditioned by being stored in an area with an ambient temperature between 5°C and 30°C for a minimum of 48 hours before using
  • Do not thin with solvents. Solvents will prevent proper curing and change mechanical properties
  • Components B & C must be kept dry
  • Avoid splitting pre-batched units to mix. Mix complete units only
  • For smaller sections 1 x A and 1 x B components can be mixed
  • Cold ambient, substrate or material temperatures will influence the curing and flow characteristics



Application


Substrate Quality

Laitance and all loose material including dust, oil and grease should be removed in order to produce a sound substrate. Ensure grouting area is dry.

 

Substrate Preparation

Substrates must be sound, dry, clean and free from laitance, ice, standing water, grease, oils, old surface treatments or coatings, and all loose or friable particles must be removed to achieve a laitance and contaminant free, open textured surface. Surface and base plate contact area must be clean and sound.

Ensure shuttering is grout-tight and constructed of materials that will not distort during placement. Heavy duty plywood (e.g. 3/4 inch, or 19mm, thick) or steel are recommended and will have prolonged working lives allowing multiple use.

Ensure that sufficient head is allowed to facilitate continuous discharge and that the gap is not less than 25mm from the edge of the plate. Ensure that the other edges are at least 20mm thick and that the grout is haunched up to level with the top surface of the base plate.

 

Mixing

To achieve the most consistent grout mix, mechanical mixing is recommended. Mixing may be carried out in the plastic package pail or a similar suitable mixing vessel. Suitable mixers include a slow speed, high torque drill and grout stirrer. For full pack mixing of Railfast Grout, pour all of the resin contained in the two tins within the pack into the mixing vessel. Slowly add the catalysed filler whilst continuously mixing. Continue mixing after all the catalysed filler has been added until the mix is powder free and homogeneous. The chemical reaction (i.e. setting speed) is rapid. The mixed grout should be placed immediately after mixing. The working time may be extended in cold ambient conditions and may be shortened in hot ambient conditions.

 

Application - Grouting Under Base Plates

Place grout continuously into the work area from one side only. Where further mixes are required to fill the void, these should be prepared in sequence such that pouring is continuous. Place mixed grout within 10 minutes after start of mixing. Do not disturb the grouted section until the grout has hardened. Tools and mixing equipment should be cleaned with solvent before grout has hardened. Set grout can only be removed mechanically.

 

Application - Grouting Under Base Plates

Mixed Railfast Grout should be poured into grout feeder boxes, allowing the gap between lower steel plates to be completely filled with Railfast Grout. The Railfast Grout should be brought up to a level within the box such that any small degree of volume change will be accommodated by further ingress of the grout.

 

Cleaning of Tools

Clean all tools and application equipment with Sika Thinner C Cleaner immediately after use. Hardened/cured material can only be removed mechanically.
