Sika WT-200 P

Sika WT-200 P is a dual-action admixture: it functions both as an integral waterproofing agent and as a crystalline waterproofing admixture for concrete. It is used to reduce concrete permeability and to enhance its self-healing properties through the formation of crystalline compounds that seal microcracks.

Specifically designed for the production of high-quality watertight concrete
Part of the Sika Watertight Concrete System

Can be used in all types of underground or above-ground watertight structures, such as:

Basements of multi-storey buildings and residential properties
Parking areas
Production and utility rooms
Tunnels
Swimming pools
Dams
Water tanks and reservoirs
Wastewater treatment facilities
Underground public spaces (shopping malls, passenger stations, etc.)

Reduces water penetration under pressure
Decreases capillary water absorption
Through the crystallization process, it promotes the self-healing of concrete in case of crack formation
Improves concrete resistance to aggressive chemicals
Also available in water-soluble bag form
