Building a Solid Base is the Foundation to a Strong Structure
In the manufacturing process of concrete foundations, Sika products are used from the very beginning.
Sika’s solutions cover the full range of technologies used for the concrete production, in the concrete waterproofing and repair and in the grouting before the erection of the tower.
Starting from the correct mix design of the concrete, followed by the waterproofing and repair of the concrete and finishing with the grouting works, before the erection of the tower, Sika will support your project during the complete process and a complete solution supplier.
Admixtures and Additives
Sika develops and markets numerous admixtures and additives for the use in concrete, cement, and mortar production. These products enhance specific properties of fresh or hardened concrete, such as workability, watertightness, durability, or early and final strength. Sika’s admixtures and additives such as
- Mould Release Agents, such as Sika® Separol® product- With the addition of Superplaticizers Sika® ViscoCrete® to concrete allows the reduction of the water-cement ratio witout incluencing the workability (rheology) of fresh concrete.- Micro-and Macrofibers SikaFiber® range covers the reduction of early age shrinkage cracks and fire resistance- SikaRapid® accelerator technology leads to an overall optimized production process- Sika® Retarder range controls the cement hydration.
enable high quality, sustainable, time efficient, and cost optimized production of concrete structures in precast concrete and ready-mix concrete industries.
Waterproofing Surfaces
Waterproofing systems for below ground structures are faced with more stringent requirements regarding durability, exposure and stress conditions, construction method and sequence, ease of application, and total cost management. Sika is supplying
- waterproofing mortars for old and new concrete structures for lower requirements as well as- Waterproofing coatings which are easy, fast and secure to apply.
Grouting to fill Voids
Sika grouting technologies are cementitious, resin or polyurethane binders. Engineering grouts are designed to completely fill voids and transfer load. SikaGrout® and Sikadur® are ideal for the filling of - vertical or horizontal joints; - for levelling of interacting concrete surfaces and filling very small holes - Sika cable grouts fill small crevices around post tensioned wires to protect the steel from corrosion.
Concrete Repair and Reprofiling
In some cases, concrete deterioration lead to crack formation. For these cases, Sika has the complete portfolio of injection products that will solve the problem.
