CHARACTERISTICSÖKOPLAST
® 2K 20B is a polymer-modified, fiber-reinforced thick waterproofing sealant based on a bitumen emulsion and containing a hydraulically setting powder. It is resistant to the aggressive substances normally occurring in the ground and is not harmful if it enters the groundwater.
In its hardened state it is resistant to frost and gritting salt.
- Easy to apply
- Good smoothability
- Rapid full setting
- Fiber-reinforced
- Complies with DIN 18514
INGREDIENTSBitumen, polymers, emulsifiers, functional fillers, fibers, hydraulic binders
USEÖKOPLAST
® 2K 20B for waterproofing structural components in contact with soil as per DIN 18533 on walls, foundations and floor slabs in contact with soil as well as earth-covered ceiling panels.
• Soil moisture and non-pressing water W1-E
• Against external pressure water, moderate effect W2-E
• Against non-pressing water on earth covered ceilings
W3-E
• Against spray water on the wall plinth as well as
capillary water in and under walls in contact with soil
W4-E
• For waterproofing wall connections to WU concrete
as well as construction joints and butt joints of
components made of concrete with high water
resistance
• On non-plastered brickwork, concrete, plaster MG P II
and P III as well as on old cleaned bitumen seals
• As an adhesive for insulation, protective and drain
boards
Areas of application:
- Cellars in residential and industrial buildings
- Floor slabs
- Underground garages
- Balconies, patios
- Wet rooms, showers
- Retaining walls
- As an adhesive for insulation, protective and drain boards
PREPARATION OF THE SURFACEThe substrates must be firm, capable of taking loads, free of dust, dirt and mortar residues. Clean the base projections thoroughly. Completely remove sinter layers and impurities.
Outside edges have to be broken, all internal corners have to be designed as coving with INTRASIT
® SM 54Z or the fast setting INTRASIT
® RZ1 55HSP waterproof mortar. Paint or spray IMBERAL
® Aquarol 10D as an undercoat on all absorbent mineral surfaces.
The substrate can be slightly moist. When there is the danger of penetration by moisture from the back, carry out an intermediate sealing with INTRASIT
® DS1 54Z, INTRASIT
® Poly-C1 54Z or IMBERAL
® RSB 55Z. Old bitumen sealing that has stuck fast can be reworked with PMBC after cleaning. Close open joints, pores and voids up to 5 mm with ÖKOPLAST
® 2K 20B as the scratch coat. Close joints wider than 5 mm, mortar pockets and holes with INTRASIT
® SM 54Z or INTRASIT
® RZ1 55HSP. Scratch coats and channels must have hardened before the waterproofing work begins.
APPLICATIONDIN 18533 – Waterproofing of buildings
DIN 1053 – Masonry
Follow the directive for the design and planning of structural parts in contact with the ground with plastic-modified bitumen thick coating.
Mixing:
Shortly stir the liquid component with a slowly rotating stirring tool with paddle (400 to 600 rpm) and intensively mix-in the entire powder component. The mixing process takes approx. 1 minute and is finished when the mass is homogeneous and free of lumps.
Surface sealing:
PMBC is processed in at least two passes. In case of soil moisture and non-pressing water as well as in the plinth area, the sealing layers can be applied whilst still wet. Against external pressure water, moderate effect, and with non-pressing water on earth-covered ceilings, the reinforcement IMBERAL
® VE 89V is integrated in the first layer. The second layer is sealed when the first bonding layer is no longer damaged.
Plinth and areas exposed to spray water:
When plastering subsequently or in the area of the clinker contact area we recommend waterproofing these areas with IMBERAL
® RSB 55Z.
Movable joints:
Carry out and integrate in the surface sealing expansion and structural joints with joint sealing tape IMBERAL
® FAB 89ZH.
IMPORTANT NOTES- Maintain a working temperature of +5 °C to +35 °C.
- Bubble formation due to deep pores or hollows in concrete should be prevented or reduced by means of scratch plastering.
- Do not apply the product in direct sunlight.
- If possible, arrange waterproofing penetrations in the area of soil
moisture, non-standing seepage water. Here, the bitumen thick-coating
can be processed to the penetration like channels. - Use adhesive flanges or loose/fixed flanges for passages where there is water not under pressure. Openings in accumulating seepage water or ground moisture areas must always be made with loose/fixed flange screw connections.
- Gullies must be reinforced with plate edging or sheeting, integrating a woven tape.
- Apply protective layers and protective measures according to DIN 18533.
- Any deviations from DIN 18533 must, as a rule, be contractually agreed separately.
- When laying perimeter insulation boards, also see the information sheet on the thermal insulation of components in contact with soil by the professional association Polystyrol-Extruderschaumstoff (FPX).
- Clean tools with clean water immediately after use.
SAFETY PROVISIONS/RECOMMENDATIONSPowder component contains cement and causes alkaline reaction when coming into contact with moisture or water. For further information on safety when transporting, storing and handling, please refer to the current safety data sheets.
DISPOSALThe local waste removal regulations must be observed.
