Sika Sikadur-42 Grout Pak LE

Sika Sikadur-42 Grout Pak LE is a high-strength, solvent-free epoxy grout engineered for structural stability and reliable performance in challenging industrial environments. This three-component system is pre-proportioned for consistent mixing and ease of use, minimizing dust during preparation and placement. Its low-exotherm chemistry makes it well-suited for large-volume pours without excessive heat buildup, while maintaining dimensional stability. The material bonds effectively to both steel and concrete, even in damp conditions, and withstands continuous exposure to mechanical impact, vibration, and corrosive chemicals. Designed to meet API 686 specifications, Sikadur-42 Grout Pak LE is ideal for securing heavy machinery, equipment baseplates, and crane rails where precision, durability, and long-term resistance are critical.

FAQs

What is the effective bearing area of this grout?
Approximately 90%, ensuring strong, uniform support under baseplates.

What is the recommended temperature range for storage and application?
Store between 41°F and 89°F. Condition between 73°F and 86°F for 48 hours before use.

What are the pour limitations for depth?
Minimum grout depth is 1 inch; maximum is 18 inches per lift. Contact a sales representative for pours over 12 inches.

Can this grout be used in cold weather?
Cold temperatures slow cure and flow. Material should be preconditioned and technical support consulted for installations below 73°F.

Is the grout compatible with steel and concrete?
Yes. It has a low coefficient of thermal expansion and strong adhesion to both steel and concrete.

Does the product meet industry installation standards?
Yes, it aligns with API Recommended Practice 686 for machinery installation.
