Biographical Info

Sika is a speciality chemicals company with a leading position in the development and production of systems and products for concrete, waterproofing, roofing, flooring, refurbishment, sealing & bonding and industry.

Sika develops and markets a complete range of admixtures and additives for use in concrete, cement and mortar production. These products enhance specific properties of the fresh or hardened concrete, such as workability, watertightness, durability, load-bearing capacity or early and final strength. The demand for admixtures and additives is currently on the rise, particularly due to the increased performance requirements placed on concrete and mortar, especially in urban areas and for infrastructure construction. Furthermore, the growing use of alternative cementitious materials in cement, mortar, and therefore also in concrete, increases the need for admixtures


Extended workability, controlled over several hours, is especially important for urban construction sites with congested traffic, or remote areas resulting in long transportation times. At the same time, once the concrete is placed, fast curing is of utmost importance to meet tight construction schedules. Sika ViscoFlow® is a workability enhancing admixture, based on a new inhouse-developed polymer which significantly prolongs the workability time of the fresh concrete and still ensures equally fast strength development. The workability time can be modified in accordance with project specific needs. Furthermore, the required consistency of the concrete is ensured in high as well as in low temperature climates.

Sika’s solutions also cover a full range of technologies used for structural waterproofing, including: flexible membrane systems, liquid applied membranes, waterproofing admixtures for concrete, joint sealants, waterproofing renders, injection grouts and coatings.
