Sika SikaGrout 328

Key Features of Sika SikaGrout 328

• Multiple Consistency Options
  Single material can be mixed to dry pack, plastic, flowable, or fluid consistency based on application requirements.
• Extended Working Time
  Provides up to 4 hours of initial set time in fluid consistency, allowing sufficient time for proper placement and finishing.
• High Compressive Strength
  Reaches 10,000 psi (69 MPa) compressive strength at 28 days in dry pack consistency, with excellent performance across all consistency levels.
• Non-Shrink Properties
  Shows positive expansion to ensure maximum effective bearing area and optimal load transfer without settlement.
• Premium Quality Aggregate
  Contains high-grade quartz aggregate for superior mechanical properties and long-term durability.
• Excellent Flowability
  Outstanding flow characteristics in fluid state enable complete filling of tight spaces and complex geometries.
• Non-Metallic Composition
  Will not stain or rust, making it suitable for applications where corrosion resistance is essential.
• Pumpable Performance
  Excellent grout for pumping applications, even at high flow rates, reducing labor and installation time.

Frequently Asked Questions

What mixing ratios are recommended for different consistencies? Dry pack requires 5.5-6.0 pts water per 50 lb bag, plastic needs 6.5-7.0 pts, flowable uses 7.0-7.5 pts, and fluid consistency requires 8.0-8.5 pts of water per bag.

How long does SikaGrout 328 take to set?
Set times vary by consistency: dry pack has initial set under 15 minutes and final set under 2 hours, while fluid consistency provides over 4 hours initial set time and under 8 hours final set time.

What is the maximum thickness for application?
Standard application thickness ranges from 1/2 inch minimum to 6 inches maximum. For thicknesses over 6 inches, consult Sika’s Technical Service Department.

What compressive strengths can be expected?
At 28 days: dry pack reaches 10,000 psi, plastic achieves 8,200 psi, flowable attains 8,000 psi, and fluid consistency reaches 7,500 psi compressive strength.

Can aggregates be added to extend the material?
Yes, for deeper applications in plastic and flowable consistencies, 25 lbs of 3/8 inch clean, non-reactive coarse aggregate can be added per 50 lb bag.

What temperature conditions are required for application?
Product, ambient air, and substrate temperatures should all be above 45°F (7°C), with optimal product temperature between 65-75°F (18-24°C).

How should the surface be prepared?
Surfaces must be clean, sound, and free of oil, grease, and loose materials. Concrete should be roughened and in saturated surface dry (SSD) condition with no standing water during application.

What standards does SikaGrout 328 meet?
Meets ASTM C-1107 (Grade B & C) requirements and is USDA certifiable for food processing environments where required.
