Waterproof concrete is an impermeable concrete used for long-lasting, durable watertight construction. To improve the impermeability of the concrete, water-resisting admixtures can be added. Nevertheless, design and construction of a watertight concrete structure is a system approach, and waterproof concrete is only one element of it. Water impermeability is determined by fulfilling requirements to limit water permeability through the concrete itself, the joints, installation parts and cracks.
Key Advantages of Sika® Watertight Concrete System
- Time saved at design and construction stages, as the need for complex detailing and installation is eliminated
- Cost effective in comparison with other systems
- Delivers maximum usable area to the occupier
- Peace of mind for the owner, designer, contractor, and end user of the building

Sika® Watertight Concrete System Components
Sika® WT-100 series is a range of pore blocking admixtures.
Sika® WT-200 series is a range of crystalline pore-blocking and enhancement self-healing admixtures.
Sika® ViscoCrete® can be used for lower water-cement ratio, which reduces the size of the capillary structure.
Sika® Waterbar are used to waterproof expansion (movement) and construction (no-movement) joints.
SikaSwell® profiles and sealants swell in contact with water to seal construction joints (non-movement joints), service entries and penetrations.
SikaSwell® rings and plugs and Sikadur®-31 are used to seal formwork tie bar holes against water ingress.
Sika® Antisol® is a spray-applied curing compound to prevent early moisture loss.
Sikadur-Combiflex®-SG is a high performance joint and crack sealing system.
