WATERSTOP EC PLUS
DESCRIPTION
WATERSTOP EC PLUS is comprised of a sodium bentonite/hydrophilic rubber combination designed to provide a superior watertight seal while at the same time offering the ability to work in an environment subjected to continuous wetting and drying cycles. Full hydration and/or dehydration takes approximately four days.
USES
WATERSTOP EC PLUS is used to seal static construction joints in concrete footings, walls, floors, tunnels, and parking and plaza decks and to prevent water migration. WATERSTOP EC PLUS has superior performance when used under conditions of extreme water head.
FEATURES/BENEFITS
- When properly applied, stops water migration through cast-in-place concrete construction joints after confinement.
- Returns to original placement and size after one prolonged hydration cycle.
- Resistant to a variety of chemical contaminates common to urban water and soil samples.
PACKAGING
Standard rolls sizes:
½” x 1″ x 16′ 8″ (12.7 mm x 25.4 mm x 5.1 m)
¾” x 1″ x 16’8″ (19.1 mm x 25.4 mm x 5.1 m)
Each carton provides 100 LF (30.5 lm) of coverage. Rolls are packaged six per carton. Make sure to protect product from moisture in storage. Store on skid or pallet. Cover with polyethylene or tarp.
APPLICATION
Surface Preparation … Surface should be clean and dry. For optimum adhesion to concrete, use CLAY-TITE MASTIC from W. R. MEADOWS. Place bead of material across surface before installation of WATERSTOP EC PLUS. Concrete should cover 2″ (50 mm) surrounding the WATERSTOP EC PLUS application area.
Application Method … After applying CLAY-TITE MASTIC, remove the thin liner and press the product into place. The product should be applied with the nylon side up. After WATERSTOP EC PLUS is hand-pressed into place, then install standard masonry nails. The nails should be placed 12″ (304.8 mm) apart. After the nails are placed, release the thick liner. Then concrete can be poured or placed.
PRECAUTIONS
Do not install in standing water or over ice. WATERSTOP EC PLUS is not designed, nor intended to function, as an expansion joint sealant. WATERSTOP EC PLUS is designed to seal structural concrete joints with a minimum 3,000 psi (20.7 MPa) compressive concrete strength. If WATERSTOP EC PLUS has eclipsed 24 hours of continuous submersion, allow an appropriate or equal time to dry before placement of concrete or replace with new product. If elevated levels of chemical contamination or high levels of salt water are known to exist on the site, use WATERSTOP EC PLUS HSR from W. R. MEADOWS. CLAY-TITE MASTIC may be applied over damp surfaces, but must not be applied over dust, debris or standing water as proper adhesion will not take place
