Simple & safe to the goal
-
4. Drill boreholes into one horizontal masonry joint row. Diameter: 16 mm, length of each borehole: 5 cm shorter than masonry thickness; interval: 8 - 12 cm. When the maximal water level is high and external waterproofing does not exist, drill the holes in the highest horizontal masonry joint row under the basement ceiling.
-
6. Use the manual gun no. 3 and its accessories (injection pipes, adapter, etc.) for injecting the cream weber.tec 946 without pressure into the boreholes.
Alternative: use Gloria equipment for spray application out of the plastic bucket. -
7. Fill the cream weber.tec 946 in the whole length of the holes. Start the injection at the hole end and step back.
-
8. Apply a bonding layer with the watertight mortar weber.tec 933 (brush consistency) on the groove area (angle concrete slab/basement wall); afterwards fill the recess with the mortar (trowel consistency) with a flat trowel on the fresh bondcoat.
-
9. Close the clean joint network of masonry with weber.tec 933 as patching mortar in max. 10 mm thickness, using a flat trowel.
-
11. Apply weber.tec 933 as groove mortar (trowel consistency) with the preformed rounded trowel weber.sys Hohlkehlenschlittten along the pre-said angle.
-
12. After drying the bondcoat weber.tec 933 apply the waterproof render weber.tec 934 in approx. 20 mm thickness as thrown-on with a hawk trowel. Rule level with aluminium beam or flat trowel. Depending on the type of top render/plaster, comb horizontally with a notched trowel or smooth with a damp brush or sponge float.
-
13. Apply the ready-to-use textured lime render/plaster, weber.cal 286 with a plastic trowel on top of the smoothed waterproof render. Smooth with a sponge float.
