HYDRASTOP SBW
Suspended Balcony Waterproofing Membrane

DESCRIPTION
HYDRASTOP SBW is a 60 mil composite, self-adhered sheet membrane comprised of a non-woven fabric, elastomeric membrane, and coated release paper.  Once concrete is poured against HYDRASTOP SBW and the concrete cures, a mechanical bond forms that secures the concrete to the membrane.

USES
HYDRASTOP SBW is used as a pre-applied waterproofing membrane specifically designed for horizontal suspended balcony slabs that will receive a concrete topping.

FEATURES/BENEFITS

  • Provides a waterproof seal between the membrane and poured concrete deck.
  • Helps prevent moisture migration into the structure.

PACKAGING
939.8 mm x 19.8 m (37″ x 65′) long rolls, one roll per carton.

STORAGE AND HANDLING
Store membrane cartons on pallets and cover if left outside. Keep materials away from sparks and flames.

APPLICATION
Surface Preparation … Inspect all surfaces for any conditions detrimental to the proper completion of the work. Surfaces should be structurally sound. Remove debris or any other foreign material that could damage the membrane.

Application Method … HYDRASTOP SBW may be applied at temperatures down to 5° C (40° F).

Installation and Factory Edge … Position first roll of HYDRASTOP SBW and remove release paper on edge.   Pull balance of release paper off, running roll from low to high points, so all laps will shed water.  Roll press into place with a tile-type roller.  Stagger end laps and overlap all seams at least 2″ (50.8 mm).  Prior to placement of overlapping roll of HYDRASTOP SBW, apply MEL-PRIME W/B in the seam overlap area, position HYDRASTOP SBW, and roll press into place.

Remove the balance of release paper and roll press membrane into place.  Apply a band of HYDRALASTIC 836 over top of the HYDRASTOP SBW joint a minimum of 3″ (76.2 mm) wide and 90 mils thick.

Apply PRECON FABRIC TAPE from W. R. MEADOWS over construction, control, and all expansion joints and over cracks greater than 1/16″ (1.6 mm) wide prior to the application of HYDRASTOP SBW.  For cracks and joints up to 1/16″ (1.6 mm), no additional treatment is needed.  For joints >1/16″ (1.6 mm) and <1/4″ (6.4 mm), joints should be filled with BEM from W. R. MEADOWS prior to installation of HYDRASTOP SBW.  For joints >1/4″ (6.4 mm), fill with BEM and a 9″ (228.6 mm) strip of PRECON FABRIC TAPE over the joint prior to installation of HYDRASTOP SBW.  Use MEL-PRIME W/B prior to application of PRECON FABRIC TAPE.  Please contact W. R. MEADOWS for specific details regarding expansion joint installations.

END LAPS … Overlap membrane a minimum of 2″ (50.8 mm).  Prior to overlap, apply MEL-PRIME W/B from W. R. MEADOWS in area to be lapped.  Roll press membrane into MEL-PRIME W/B.  Apply a band of HYDRALASTIC 836 over top of the HYDRASTOP SBW a minimum of 2″ (50.8 mm) wide at 90 mils thick.

Penetrations and Protrusions … Detail around all horizontal and vertical penetrations using BEM, HYDRALASTIC 836, or MEL-ROL LIQUID MEMBRANE (two-component) from W. R. MEADOWS.   Apply BEM, HYDRALASTIC 836, or MEL-ROL LIQUID MEMBRANE by forming a fillet around the pipe or protrusion, overlapping the fabric side of HYDRASTOP SBW and the protrusion a minimum of 64 mm (2.5″).  If the gap between the protrusion and the membrane is greater than 13 mm (½”), apply PRECON FABRIC TAPE over uncured BEM, HYDRALASTIC 836, or MEL-ROL LIQUID MEMBRANE.  All penetration and protrusion surfaces must be clean, rust-free, and sound prior to application of BEM, HYDRALASTIC 836, or MEL-ROL LIQUID MEMBRANE.

Patching … Prior to pouring, inspect membrane for punctures or damage and repair as necessary with BEM, HYDRALASTIC 836 and/or DETAIL FABRIC.

PRECAUTIONS
Concrete should be poured within 60 days of membrane installation. For installations below 4° C (40° F), contact W. R. MEADOWS technical services.  When using bar supports, use those with a flat bottom.
