    Fastfill WP is a rapid setting, polymer modified cementitious water plugging mortar for arresting water seepage and infiltration under pressure through cracks, joints and voids in concrete and masonry. Fastfill WP can also be used for rapid sealing and jointing in and around pipework, or in water retaining structures.

    Fastfill WP is a single component, polymer modified, fibre reinforced, Portland cement-based water plugging and sealing compound. When mixed with water it exhibits unique hydraulic properties to produce a rapid setting mortar which can arrest water seepage and infiltration through joints, cracks or porous areas in concrete and masonry structures.


    • Pre-packaged material requiring mixing with clean water.
    • Low shrinkage and high bond strength ensure monolithic performance and a watertight seal.
    • Sets in 2 minutes at 20ºC, yielding a durable, high strength mortar.
    • Physical properties of cured materials similar to base concrete.
    • Polymer modified to ensure enhanced adhesion in jointing situations and prevent wash out.
    • Non toxic when cured.
    • No more hazardous to handle than ordinary Portland cement.

    Surface preperation

    Mechanically remove all damaged concrete and masonry back to a sound core. Joints and cracks should be square cut or ideally dovetail cut out to a minimum depth and width of 20mm. On cutting back, feather edges and V-cuts must be avoided. The perimeter of the area should be broken to a depth of 10mm preferably using a power chisel.

    The areas to be treated must be free from all unsound material, i.e. dust, oil, grease, corrosion by-products and organic growth. Smooth surfaces should be roughened, and all loose material and surface laitance removed using high pressure water techniques.

    The prepared substrate should be thoroughly soaked with clean water until uniformly saturated without any standing water.
