Fastfill - repair and profiling of vertical and horizontal in situ and precast concrete
(EN1504-3 class r4, dwi 31, bba, wras)

Flexcrete's Fastfill has been developed for the repair and profiling of vertical and horizontal in situ and precast concrete where a rapid setting, yet durable high strength mortar is required. It is ideally suited for the repair of concrete in locations which cannot be taken out of service for long periods and which are subsequently subjected to heavy wear. Typical applications include repairs to roads, runways, bridges, decks, floors and footpaths. FASTFILL can be used as supplied up to 100mm deep, or can be bulked out with sharp aggregate for full section repairs up to 300mm.

Fastfill is a single component, polymer modified, fibre reinforced, Portland cement based repair compound, which is physically and chemically compatible with the host concrete. It exhibits unique hydraulic properties to produce a rapid curing mortar exhibits unique hydraulic properties to produce a rapid curing mortar with enhanced polymeric properties and reliable strength development which is not significantly affected by low temperature use.

Advantages of Fastfill

User friendly: Pre-packaged, mixed with clean water on-site. Part bags can be mixed. Can be bulked out with sharp aggregate for deep repairs. Reliable, easy to use.
Low shrinkage: Maintains high bond strength to substrate and ensures monolithic performance of the repair.
Rapid setting: Sets in 10 minutes at 20°C, yielding a durable, high strength mortar.
Compatible: Physical properties of cured materials similar to base concrete.
Polymer modified: Ensures enhanced adhesion and low permeability giving excellent protection from acid gases, moisture ingress and chlorides.
Compliance: Fully complies with the Highways Agency Standard BD 27/86 for the repair of Highway Structures. Approved by the BBA, Certificate No. 05/4276.
Innovative: Incorporates the latest proven cement chemistry, polymer and fibre technology.
Fibre reinforced: Improved tensile and impact strength. Excellent low sag properties.
Safe: Non-toxic when cured and is listed as authorised under Regulations 31 for use in the supply of water for drinking.
