SikaGrout-295 US is a one-component, cement-based, nonshrink grout engineered to deliver exceptional mechanical resistance in demanding structural applications. This ready-to-use formulation requires only the addition of water, making it ideal for contractors and engineers who need reliable performance without complex mixing procedures. With its fluid consistency and self-leveling properties, it easily fills cavities, gaps, and recesses while providing excellent flow characteristics for placement under machine bases, sole plates, and structural supports.
This high-strength grout achieves 8,800 psi compressive strength in just 24 hours and reaches 13,100 psi at 28 days, ensuring rapid project completion and long-term structural integrity. Its slight positive expansion compensates for shrinkage typically associated with cement-based materials, while the chloride-free formulation protects embedded steel reinforcement from corrosion. The material’s waterproof properties and resistance to oils make it suitable for both interior and exterior applications across industrial, commercial, and infrastructure projects.

Frequently Asked Questions
What is the recommended thickness range for SikaGrout-295 US?
The grout can be applied from a minimum thickness of 3/8 inch (10 mm) to a maximum of 2 inches (50 mm) in a single lift. For thicker applications, multiple lifts can be installed.
How long should I wait before placing the grout after mixing?
SikaGrout-295 US should be placed immediately after mixing, with placement completed within 10 minutes maximum to take full advantage of its expanding characteristics.
What water-to-powder ratio should I use?
Mix 11.5-12% water by mortar weight, which equals approximately 6 pints, 5 fl. oz. to 6 pints, 10 fl. oz. (about 3 liters) per 55 lb. bag.
What surface preparation is required?
Surfaces must be clean, sound, and profiled to ICRI CSP-4 standard. Remove all contaminants, laitance, and bond-inhibiting materials. Bring concrete to saturated surface dry (SSD) condition before placement.
Can it be used in exterior applications?
Yes, SikaGrout-295 US is suitable for both interior and exterior applications and provides waterproofing properties resistant to water intrusion and oils.
What is the shelf life and storage requirements?
The product has a 12-month shelf life when stored in original, unopened packaging in a cool, dry place at 40-95°F (4-35°C). Protect from moisture during storage.
How should the material be mixed?
Use mechanical mixing with a low-speed drill (400-600 rpm) and mortar paddle, or an appropriate mortar mixer. Mix for a maximum of 3 minutes until homogeneous and lump-free. Do not hand mix.
What curing requirements are needed?
Moist cure exposed surfaces for a minimum of 3 days using wet burlap, polyethylene sheeting, or water mist. Alternatively, apply ASTM C309-compliant curing compounds. Keep forms in place for at least 3 days.
