Wall junction of an exterior walkway.

Structure type

Walkway or path outside the building finished with tiles or stone elements (porphyry, limestone, granite).

Detail

Waterproofing of the cementitious base before laying the screed.

Application cycle

1. RALLK ElastoKappa waterproofing coat, applied on the blinding concrete or the base slab of the outdoor walkway next to the wall and turned up vertically onto the plinth plaster.
2. Sand-cement screed more than 4 cm thick, or RALLK Massetto K BS where it must be thinner than 4 cm to match the finished levels. The screed under the ceramic or stone tiles must have suitable falls to drain rainwater away from the base of the wall.
3. RALLK Kerasiv K Flex adhesive for laying ceramic or stone tiles outdoors, in small or large formats.
4. Ceramic or stone finish covering.
5. Protective water-repellent exterior plinth plaster, at least 2 cm thick, made with RALLK Muro K Idro on brick, solid brick, concrete or sand-cement block walls, where the plinth also needs restoring.

Additional information

1. The screed under the ceramic or stone tiles must have suitable falls to drain rainwater away from the base of the wall.
2. If applying two coats of waterproofing, wait at least 24 hours between the first and second coat.
3. Lay the ceramic or stone tiles at least 24-48 hours after applying the waterproofing.
4. Make sure the waterproofing is turned up onto the plinth plaster to the height of the skirting, if there is one, or at least up to floor level. A 120-150 g/m² glass fiber reinforcing mesh, or a rubberized band or tape, can be embedded in the waterproofing at the upturn corner.
