SikaShield® W159 ED 1,5 mm
Bituminous waterproofing membrane wet applied
SikaShield® W159 ED 1,5 mm is an adhesive bituminous waterproofing membrane wet applied to the concrete surface by the adhesive mortar SikaShield® W1 IN. It has a thickness of 1.5 mm and is flexible at -15 °C. It is reinforced with a cross-laminated PE film, which gives high mechanical properties to the membrane. The top surface and the underside have a removable liner over the adhesive compound for an easy application.
- No-torch application allows for safe installation in confined spaces
- Fully bonded system ensures reliable waterproofing
- Watertight against lateral water migration
- Can be applied on wet concrete
- Fast and easy installation
Usage
The Product is used as a waterproofing membrane for:
- Basements and other below ground structures
- Vertical reinforced concrete walls
- Single and strip foundations
The Product is used as a:
- Single layer under heavy protection
- Base sheet in multi-layer systems
Please note:
- The Product is not suitable for roofs permanently exposed to UV radiation.

SUBSTRATE QUALITY
SYSTEM DESIGN
Consider the following when designing the system:
- The supporting structure must be of sufficient structural strength to support all new and existing layers of the system build-up.
- If used as a roof system, the complete system must be designed to withstand and be secured against wind uplift loadings.
SUBSTRATE CONDITION
The membrane is applied directly onto the adhesive mortar SikaShield® W1 IN. Refer to the PDS of that product for information on substrate condition requirements.
APPLICATION
IMPORTANT
Unrolling at low temperatures
At low temperatures, the membrane becomes less flexible.
- Be careful when unrolling to avoid damaging the membrane.
IMPORTANT
Damage through footwear
Footwear with spikes or sharp protrusions may puncture the membrane.
- Use footwear with a flat profile when walking over the membrane.
IMPORTANT
Application at less than +5 °C
When applying the membranes at temperatures lower than +5 °C, use heating equipment to ensure that the substrate temperature is within the given temperature range.
Seasonal symbol
Note: If a seasonal symbol is printed on the roll’s label, it is advisable to use the membrane during the indicated season.
Tackiness at high temperatures
Note: When laying the membrane at high temperatures, the integral adhesive will become ‘tacky’ and may restrict laying operations.
ALIGNMENT
IMPORTANT
Avoid coinciding joints
To avoid coinciding joints, lay the membranes parallel to one another. When applying on another bituminous membrane, make sure to straddle the overlaps of the previous layer.
- Unroll the membrane.
- Align the membrane.
- Re-roll the membrane before application.
WET APPLICATION
Preconditions
- Before the application of the adhesive mortar, the concrete substrate has been saturated with water.
- The adhesive mortar SikaShield® W1 IN has been applied onto the substrate and is still wet.
- Lay the membrane directly over the wet adhesive mortar.
- At one end of the membrane, peel away part of the release liner from the membrane’s underside.
- Bond this end of the membrane to the adhesive and the substrate.
- Continue to peel away the release liner sideways from the rest of the membrane’s underside.
- Bond the rest of the membrane to the adhesive and the substrate.
- IMPORTANT If the ambient temperature is below +10 °C, seal the membrane overlaps by heating them with a gas torch or with hot air. Seal the membrane overlaps to avoid trapping the adhesive under the overlap, which can compromise the adhesion.
- Roll the surface of the applied membrane with a roller from the centre to the edge to remove any air bubbles.
- Push any excess of adhesive towards the opposite direction of the sealed side overlap.
- Allow the adhesive mortar to cure for at least 24 hours at +25 °C before you start backfilling.
- Backfilling to be done within 7 days after completion of application.
DETAILING
- Use a sharp knife to cut in all details such as internal and external corners, upstands, vent pipes, drains, support metalwork etc.
Refer to the relevant method statement for further information on detailing.
