Engineering grouts play a critical role in ensuring the safety and stability of structural elements — transferring loads efficiently, filling voids completely, and maintaining long-term performance under the toughest conditions.
Sika’s range of high-performance cementitious and resin-based grouts are developed to meet the exacting demands of modern construction and maintenance. Whether used for machine baseplates, bridge bearings, precast elements, or rail fixings, our grouts deliver proven performance, consistent quality, and easy application.

FAQs
Cementitious grouts are suitable for general use, such as securing structural baseplates where loads are mainly static and the environment is not highly aggressive.Use epoxy grouts for high-performance, heavy-duty, or chemically aggressive environments, especially with dynamic loads.
Cementitious Grouts are designed for thicker sections.• Typical minimum thickness:o Around 10–25 mm o If you try to apply them thinner, the aggregate size and shrinkage risk make it unsuitable.• Maximum thickness per pour: Up to 500 mm.Epoxy Grouts (e.g., Sikadur®-42 HE) can be applied much thinner because they have no large aggregates and very low shrinkage.• Typical minimum thickness:o As low as 5–10 mm.• Maximum thickness per pour: Often up to 150 mm, depending on heat generation during curing.
Epoxy grouts are the recommended choice, such as Sikadur®-42 HE, which is:• Three-component epoxy resin grout.• Extremely high compressive and tensile strength.• Excellent adhesion to concrete and steel.• Resistant to vibration, impact, oils, fuels, and chemicals.• Designed specifically for heavy machinery, dynamic loads, turbines, compressors, pumps, crane rails. Recommended for dynamic loading.
Specially formulated cementitious grouts can be applied in low temperatures (e.g., 0°C).At lower temperatures, curing is slowed and strength development may take days → precautions should be taken to protect the product.
SikaGrout®-9500, -9550, and -9400 are ultra-high strength grouts (≥135 MPa) with exceptional early strength (up to ≥70 MPa at 24 h), fatigue resistance, and durability. SikaGrout®-9550 is shrinkage-compensated, highly flowable, and chloride-free for offshore wind applications, while -9500 offers robust pumpability and cold-weather performance. SikaGrout®-9400 is ideal for onshore wind turbine bases and demanding infrastructure projects.
Grout thickness depends on the product: SikaGrout®-111 GP and -212 Fluid cover 10–100 mm, suitable for general-purpose or engineering applications like structural bases. Ultra-high-strength grouts (SikaGrout®-9400/9500/9550) range from 10–30 mm up to over 100 mm, ideal for demanding projects such as onshore/offshore wind turbines and heavy-duty infrastructure, providing high strength and durability across challenging conditions.
Parex 100 Newton Grout AW (AW GB) is an ultra-high-strength, cementitious grout with anti-washout properties, ideal for underwater applications. Pre-packaged and mixed with water, it is non-shrink, freeze-thaw stable, and resistant to seawater, oil, and mild alkali. Perfect for offshore repairs, wind turbine bases, piers, jetties, and slipways, making it a reliable choice for tidal-zone grouting.
