+5 °C min. / +35 °C max.
 
Injection works should be carried out when the temperature does not drop below 0 °C for at least 48 hours after application to allow the material to diffuse optimally.

Number of sausages (in brackets: cartridges) required:

Note: Variable site conditions can obviously cause variations in consumption. Always allow at least an extra 10 % when estimating the quantity of material required.

Important: In all cases the new damp proof course shall be installed in accordance with the relevant code of practice, e.g. British Standard Code of Practice for “Installation of Chemical Damp Proof Courses” BS 6576 (2005) 

Drill holes
For treatment to be effective, the correct volume of SikaMur® InjectoCream-100 must be used. The system requires 12 mm diameter holes to be drilled at horizontal centres no greater than 120 mm apart. The depth of the holes required for various wall thicknesses is shown in the table below. For all other wall thicknesses, the depth of the holes shall be within 40 mm of the opposite side.
Drill horizontally, directly into the mortar course, preferably at the base ends of the bricks of the course selected.
After the drilling operation, each individual hole needs to be thoroughly cleaned using a clean compressed dry air blower.

Depth of 12 mm diameter hole required for SikaMur® InjectoCream-100 in various thicknesses of wall:

Solid brick walls
Solid brick walls can be treated from one single side in one operation. This will depend on the length of the drill bit available. Drill the selected masonry mortar course at the prescribed centres to the appropriate depth in accordance with the table above.

Cavity walls
Cavity walls may be treated from one side in a single operation or each side wall may be treated separately. When undertaking the treatment from one side, drill completely through the selected mortar course, allow the drill bit to pass across the cavity and then drill into the other wall of brickwork to be within 40 mm of the opposite (rear) side. The viscosity of SikaMur® InjectoCream-100 is such that it is possible to treat each side wall from a single drilling operation. Always ensure that the cavity is clear before treatment.

If each side wall is treated separately, treat each side wall as an individual solid brick wall.

Random stone and rubble infill walls
Follow the mortar course at the appropriate selected level. If a stone is of a porous type, e.g. sandstone, then the drilling can be made directly into the porous stone. The variable thicknesses of stone walls and the possibility of rubble infill dropping and blocking the injection holes can cause difficulties for any injection system. If these sorts of problems occur, either drill into 50 % of the wall thickness from both sides at a corresponding height, or drill additional holes adjacent to the obstructed holes, to ensure that the correct volume of SikaMur® InjectoCream-100 can be injected to form a continuous Damp Proof Course.

Where required remove skirting boards and/or render/plaster to identify and expose the original masonry and the appropriate mortar course to be treated. Measure the thickness of each wall to be treated. Set the depth gauge of the drill or apply tape to the drill bit in order to identify the correct drilling depth.
