The Silikal R17 mortar system is engineered for high-performance concrete and surface repairs, offering excellent adhesion and long-lasting durability. Each system includes a 15 kg bag of filler and a 2-liter can of hardener liquid. When mixed, the two components form a pourable, reactive resin mortar that is easy to apply and cures rapidly.

For vertical or sloped surfaces, Silikal offers SILIKAL® R 17 thix, a thixotropic variant designed to stay in place without sagging. As with any professional-grade repair material, proper surface preparation is essential. To ensure maximum bond strength and long-term performance, it’s recommended to apply a primer such as SILIKAL® R 52 or R 51 before the mortar is used.

A standard set of SILIKAL® R 17 covers approximately 1 m² at a thickness of 1 cm, making it an efficient and precise solution for localized repair jobs. Additionally, special grades of SILIKAL® R 17 are available to suit specific technical requirements and project conditions.

• Only cure above 0 °C, limiting their use in colder environments

• Require long setting times, delaying project completion

• Offer low flexibility and limited resistance to mechanical wear and aggressive chemicals

What’s less known—but increasingly important in modern construction—is that concrete repair can also be done using resin-bonded mortars. Instead of relying on cement as a binder, these advanced mortars use synthetic resins (such as methyl methacrylate or epoxy) to bond mineral aggregates. This innovative approach not only matches but often exceeds the compressive strength of traditional concrete.

In fact, resin-based concrete repair mortars outperform standard mortars in durability, chemical resistance, curing speed, and long-term performance. Despite some initial skepticism about using synthetic materials for structural applications, resin mortars have proven to be superior in both strength and resilience.
