Applications

• Basements of residential and commercial buildings
• Floor slabs
• Underground garages
• Balconies, terraces
• Wet rooms, shower facilities
• Retaining walls

Composition

• Liquid component / component A: bitumen emulsion
• Powder component / component B: contains Portland cement

Substrate

Properties/tests

• The substrate must be solid, load-bearing and free of dust, dirt and mortar residue.
• The substrate may be matt damp.

Pretreatment

• The substrate must be prepared in accordance with DIN 18533 Part 3.
• Thoroughly clean the sole protrusions. Completely remove sintered layers and soiling.
• Outside edges are to be broken, all inside corners are to be created as coving with INTRASIT SM 54Z or the quick-setting sealing mortar INTRASIT RZ1 55HSP.

• Use IMBERAL Aquarol 10D as a primer on all absorbent, mineral substrates

  .
• If there is a risk of moisture penetration from the rear, apply intermediate waterproofing with INTRASIT DS1 54Z, INTRASIT Poly-C1 54Z or IMBERAL RSB 55Z.
• Old, firmly adhering bitumen waterproofing can be reworked after cleaning without further priming.

• Fill open joints, pores and cavities up to 5 mm with bitumen thick coating as a scratch coat. Seal joints wider than 5 mm, mortar pockets and cavities with INTRASIT SM 54Z or INTRASIT RZ1 55HSP.

• Scratch coats and covings must be hardened before starting the waterproofing work.

Processing

Mixing / Preparation / Processing

• First stir the bitumen component thoroughly before application using a powerful, slow-running dysentery mixer with stirring paddle. The powder component is then slowly sprinkled in at the specified mixing ratio while stirring continuously. Both components must then be mixed until a homogeneous, lump-free mass is formed.

Processing

• Apply with a smoothing trowel, trowel or a suitable spraying technique in the required layer thickness.
• Apply at least 2 coats. The second coat can be applied as soon as the first coat has dried to such an extent that it can no longer be damaged. In accordance with DIN 18533-3, a reinforcing insert is required for various water exposure classes. In areas at risk of cracking, such as irregular masonry, open butt joints, in coving areas and in masonry made of large-format bricks, as well as in areas subject to high loads, the VE 89V reinforcing insert must also be embedded.
• Base and splash water area: We recommend sealing these areas with IMBERAL RSB 55Z for subsequent plastering or in the area of the clinker contact surface.
• Movement joints: Movement and structural separation joints must be looped using IMBERAL FAB 89ZH joint tape and integrated into the surface waterproofing.
• Minimum layer thicknesses according to DIN 18533:
  W1-E: Wet layer thickness approx. 4.2 mm / Dry layer thickness ≥ 3 mm / Consumption: 4,6 kg/m²
  W2.1-E: Wet layer thickness approx. 5.5 mm / Dry layer thickness ≥ 4 mm / Consumption: 6,0 kg/m²
  W3-E: Wet layer thickness approx. 5.5 mm / Dry layer thickness ≥ 4 mm / Consumption: 6,0 kg/m²
  W4-E: Wet layer thickness approx. 4.2 mm / Dry layer thickness ≥ 3 mm / Consumption: 4,6 kg/m²
  The stated consumption values are minimum values. Separate professional levelling of the substrate, e.g. by scratch filling, is assumed. According to DIN 18533 Part 3, a layer thickness allowance of at least 25 % of the minimum dry layer thickness must be added.

Processing / Working time

• Can be used for approx. 4 - 5 hours after mixing.

Drying / Hardening

• The waterproofing must be completely dry to ensure the final effect and strength.

Cleaning the tools

• Clean all tools and equipment with water immediately after use.
• Hardened material can only be removed mechanically.

Notes

• Water from the cellar floor or water collected from the floor slabs and rainwater downpipes that are not yet connected must be prevented from running behind the waterproofing layer. No cohesive soils (containing clay) may come into contact with the waterproofing.
• Maintain a processing temperature of +5 °C to +35 °C.
• When applying the product, observe DIN 18533 – Waterproofing of buildings, DIN 1053 – Masonry construction and the guidelines for the design and planning of components in contact with the ground with polymer-modified bituminous thick coatings.
• Prevent or reduce blistering due to deep pores or cavities in concrete by scratch filling.
• Do not process in direct sunlight.
• If possible, arrange penetrations of the waterproofing in the area of ground moisture and non-accumulating seepage water. The thick bitumen coating can be applied to the penetration in the form of a cove.
• Use adhesive flanges or loose/fixed flanges for penetrations in the area of non-pressing water, in the case of accumulating seepage water or pressing water, loose and fixed flange screw connections must generally be used.
• Reinforce floor inlets with plate edge or clamping foils with a fabric strip in case of integration.
• Protective layers and protective measures in accordance with DIN 18533.
• Deviations from DIN 18533 must always be contractually agreed.
• When laying perimeter insulation boards, see also the information sheet for thermal insulation of components in contact with the ground from the Fachvereinigung Polystyrol-Extruderschaumstoff (FPX).
