SikaGrout 4316 is a unique ultra high-strength, hybrid performance grout that provides exceptional early and ultimate compressive strengths across a wide variety of application and service temperatures. Engineered with a novel hydraulic binder and premium mineral aggregates, this flowable and pumpable grout can be installed in challenging temperature conditions ranging from 35°F to 100°F (2°C to 38°C), making it ideal for year-round construction and maintenance operations. With proven DNV fatigue resistance testing and 20 years of validated in-service life for wind turbine applications, this grout delivers the reliability that critical infrastructure demands.
This advanced grout system achieves remarkable performance benchmarks, reaching up to 4,300 psi compressive strength in just 8 hours and ultimately delivering 16,000 psi strength at full cure. Its exceptional temperature resistance extends up to 1,000°F (538°C), while maintaining positive expansion characteristics and freeze-thaw stability. The material’s 95% effective bearing area ensures even load distribution, while its extremely dense composition provides proven fatigue resistance for long-term durability under dynamic loading conditions.

Frequently Asked Questions
What is the recommended mixing ratio for SikaGrout 4316?
Mix one 50 lb bag with approximately 6 lbs (2.7 kg) or 0.72 gallons (2.72 L) of clean potable water. Start with 5.75 lbs of water and adjust to achieve desired flow consistency, not exceeding 6.25 lbs per bag.
How long does SikaGrout 4316 take to set?
Initial set time is 180 minutes at 72°F, with final set at 210 minutes. In cold weather (35°F), expect 180 minutes initial set and 220 minutes final set. Hot weather (100°F) accelerates to 150 minutes initial and 180 minutes final set.
What surface preparation is required?
Concrete surfaces must be clean, saturated surface dry (SSD), and roughened to CSP 5-10 following ICRI Guidelines. For dynamic applications, chip surfaces to 3/8″ roughness. Saturate concrete with water for 8+ hours before grouting, then remove standing water.
Can it be used in freezing conditions?
Yes, SikaGrout 4316 can be installed at temperatures as low as 35°F (2°C). Protect from freezing until reaching 3,000 psi strength. The cured grout exhibits excellent freeze-thaw stability with >95% durability factor.
What is the minimum placement thickness?
Minimum placement thickness is 1 inch (25 mm). For lifts exceeding 6 inches (152 mm), consult your Sika representative for specific recommendations.
How much coverage does one bag provide?
One 50 lb bag mixed with water yields approximately 0.39 ft³ (0.011 m³) of grout. Coverage will vary based on void size and geometry.
