Class R4 Waterproof Tiehole Filler (EN1504-3, WRAS)

Overview

Flexcrete's Tiefill is used for the filling of tie-holes in new construction, particularly where a rapid setting, durable, waterproof mortar is required.Tiefill is primarily used for the filling of tie-holes formed by formwork bolts in new construction, particularly where a rapid setting, durable, waterproof mortar is required. It can also be used for sealing grout holes and voids around fixings in pre-cast elements.

Tiefill is a single component, polymer modified, fibre reinforced, Portland cement based repair compound, which exhibits unique hydraulic properties to produce a rapid curing mortar with enhanced polymer properties.

Tiefill is supplied as a single component system requiring only the addition of clean water to give a rapid setting, yet durable high strength mortar. It is ideally suited for the filling of voids, particularly in new construction, which need to be rapidly put into service – such as tie-holes, grout holes and voids around fixings.

Sets in 30 minutesAdvantages

  • Incorporates the latest proven cement chemistry, polymer and fibre technology.
  • Pre-packaged materials in convenient pack sizes only requiring mixing with clean water on site.
  • High bond strength exceeds tensile strength of concrete thus ensuring monolithic performance.
  • Sets in 30 minutes at 20°C, yielding a durable, high strength mortar.
  • Waterproof seal which withstands 10 bar water pressure after only 72 hours curing.
  • 10 Bar Pressure IconPolymer modification gives enhanced adhesion and low permeability, providing excellent protection from acid gases, moisture ingress and chlorides.
  • Improved tensile and impact strength. Excellent low sag properties.
  • Non-toxic when cured and is WRAS Approved for use in contact with potable water.
  • Economic mortar generally requiring no substrate or inter-layer priming. Part bags can be mixed.
