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

PACKAGING

TECHNICAL DATA*

Compressive strength (per ASTM C 109) at:
15 minutes 850 psi (5.86 MPa)
1 hour 1225 psi (8.44 MPa)
1 day 2650 psi (18.27 MPa)
28 days 6000 psi (41.38 MPa)

Set time (per ASTM C191)
Initial: 2 minutes
Final: 3 minutes

* All technical data is typical information, but may very due to testing methods, conditions and operators.

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.
