CG-86 DOT construction-grade grout is a non-gaseous, non-shrink economical grout. It was specifically developed as a high strength, cost-effective, general-purpose grout for use across a broad range of large and small construction projects. CG-86 DOT will not rust and contains no added chlorides or gypsum. It is furnished as a pre-mixed bagged grout, ready to use – just add water onsite. CG-86 DOT may be extended for deep grouting with pea gravel for greater yield and increased economy. CG-86 DOT is freeze-thaw stable and may be used interiorly or exteriorly, above- or below-grade.

CG-86™ DOT
Construction-Grade Grout
DESCRIPTION
CG-86 DOT construction-grade grout is a non-gaseous, non-shrink economical grout. It was specifically developed as a high strength, cost-effective, general-purpose grout for use across a broad range of large and small construction projects. CG-86 DOT will not rust and contains no added chlorides or gypsum. It is furnished as a pre-mixed bagged grout, ready to use – just add water onsite. CG-86 DOT may be extended for deep grouting with pea gravel for greater yield and increased economy. CG-86 DOT is freeze-thaw stable and may be used interiorly or exteriorly, above- or below-grade.
USES
CG-86 DOT is versatile and designed for base-plate grouting, anchoring, precast wall panels, and bridge seats. CG-86 DOT is suitable for transportation, industrial, commercial, and municipal applications.

APPLICATION
Grouting application shall be performed in accordance with American Concrete Institute (ACI) 351.1R: Grouting between Foundations and Bases for Support of Equipment and Machinery and other applicable ACI recommendations.
Surface Preparation … All grout contact surfaces must be free of oil, grease, scale, penetrating sealers, or all other types of contaminates that will interfere with the bond. Mechanically roughen or high pressure water-jet the existing concrete substrate. Surface must be rough and profiled, but generally level. Grouting area must be saturated with water 12 – 24 hours prior to grouting. Remove all excess water before placing grout.
Pouring … Method of forming must provide for rapid, continuous grout placement. Ensure form is well sealed and an appropriate form release agent has been applied for that type of form.
Placement … CG-86 DOT is easily placed by pouring or pumping and compaction can be accomplished by rodding or tapping. Place grout on one side, flowing to opposite and adjacent sides, to avoid entrapment of air. When necessary, provide vent holes. Grout “head” and excess grout may be removed after initial set.
Curing … Immediately following application, cure CG-86 DOT using a suitable curing compound from W. R. MEADOWS or in accordance with ACI 308. W. R. MEADOWS recommends the 2200-WHITE series or 1130-CLEAR series. When conditions exist for rapid early water loss, the use of EVAPRE™, an evaporation retarder from W. R. MEADOWS, is also recommended.
Venting … Forming also must ensure adequate venting to avoid air entrapment. Do not make close fitting forms; allow 1/2″ (12.7 mm) clearance and 1″ (25.4 mm) for “head.”
Mixing … Small quantities of CG-86 DOT may be hand mixed in a concrete mixing pan until lump-free. For large quantities and continuous pours, use a mortar mixer with rubber-tipped blades. Mix for a minimum of three minutes or until uniform and lump-free. Use minimum water required to produce desired placement consistency. Do not mix more than can be placed in 15 minutes. Do not re-temper. Use only clean, potable water.
Set time and strength development are dependent on temperature; therefore, follow ACI methods during hot or cold weather grouting.
ACI 305 – “Standard on hot weather concreting”
ACI 306 – “Standard on cold weather concreting”
Cost reductions are realized when grouting large areas by adding washed, dried, and graded pea gravel. For thicknesses 2″ – 4″ (50.8 – 101.6 mm), add up to 25% 3/8″ (9.5 mm) pea gravel. For medium-flow mixes, 4″ (101.6 mm) and over, add up to 50% 3/8″ (9.5 mm) pea gravel, plastic mix. Addition of pea gravel is based on percentage of the weight of the dry grout.
PRECAUTIONS
Do not use as a repair mortar. (Please contact W. R. MEADOWS for specific repair mortar recommendations.) Grouting should be done using established concreting procedures according to ACI recommendations. Read and follow application information, precautions and Safety Data Sheet information.
