MEADOW-PLUG™
One-Component, Super Fast Setting,
Hydraulic Repair Mortar
DESCRIPTION
MEADOW-PLUG is a specially
blended, extremely fast setting, hydraulic cement product designed
to instantly stop running water or fluid seepage in concrete or
masonry structures. This single component, high strength repair
mortar permanently plugs non-moving cracks, joints, and voids.
USES
Once mixed with water to a putty-like
consistency; MEADOW-PLUG may be hand formed to quickly stop active
fluid leaks in basements, tunnels, swimming pools, sewers, non-potable
water tanks, voids around pipes and wall tie holes. It seals construction
joints between floors and walls. MEADOW-PLUG is versatile enough
for either vertical or horizontal applications; below, above or
on grade. Its controlled expansion formulation permanently holds
the repair in place on exterior, interior, even, underwater installations.
FEATURES/BENEFITS
- Fast initial set / Stops liquid flow immediately.
- Expands as it sets / Forms a permanent
water stop.
- Mixes with water only / Easy to use.
- Horizontal, vertical, interior, exterior
/ Highly versatile.
- Above grade, below grade, underwater /
Multi-purpose.
- Non-metallic, non-corrosive / Will not
stain.
- May be topcoated within one hour / Saves
time.
- Good sulfate resistance / Suitable for
wastewater and sewer applications.

SURFACE PREPARATION
Cut or notch out the crack, joint, or void to a minimum dimension
of ¾" x ¾". To ensure proper mechanical
lock, the bottom of the newly notched opening should be wider
than the top. (Avoid "V" type notches or cuts.) Prepare
surface in accordance with ICRI Technical Guide No. 03730. Substrate
must be structurally sound and free of grease, oil, dirt, or any
other contaminants that can adversely affect the bond. If the
crack to be repaired is dry at the time of application, substrate
must be dust free, then saturated, surface dry (SSD).
MIXING AND PLACEMENT
Mix MEADOW-PLUG with enough potable water to form a thick putty
consistency (approximately a 4:1 ratio by volume). Do not mix
more MEADOW-PLUG than can be placed in one minute. Force MEADOW-PLUG
directly into prepared crack and hold in place, maintaining pressure
until material hardens. Avoid overworking the material. Just prior
to final set, MEADOW-PLUG may be "shaved" to match the
profile of the area surrounding the patch. If repairing a dry
crack, wet cure immediately for at least fifteen minutes or until
set is fully achieved. Do not use on any moving joints.
HEALTH AND SAFETY
Refer to Product Material Safety Data
Sheet for complete health and safety information.
FOR BEST PERFORMANCE:
- MEADOW-PLUG is recommended for concrete,
masonry and block repairs only.
- Do not apply below 40º F (4º
C) or above 90º F (32º C) or when rain is imminent.
- Protect from freezing for a minimum of
24 hours.
- Do not bridge moving cracks. Extend existing
control and expansion joints through MEADOW-PLUG.
- Do not add any admixtures.
- Exceeding liquid requirements shall result
in reduced physical properties.
- Realize that set time will decrease as
the product, air, substrate and mixing liquid temperature increases
and will increase as the temperature decreases.
- Protect from conditions that may cause
early water loss: windy conditions, low humidity, high temperature
and direct sunlight. Early water loss is exasperated in thin
applications.
- Failure to follow industry standard practices
may result in decreased material performance.
- Proper application is the responsibility
of the user. Field visits by W. R. MEADOWS personnel are for
the purpose of making technical recommendations only, and are
not to supervise or provide quality control on the jobsite.
