SikaControl®-245 WT Liquid
SikaControl®-245 WT Liquid is a liquid based crystalline waterproofing permeability reducing integral admixture. SikaControl®-245 WT Liquid Liquid is formulated to meet the requirements of ASTM C494/AASHTO M 194, Type S.
- Uniform permeability reduction throughout the treated concrete volume,
- Improved resistance against hydrostatic pressure,
- Ability to seal non-moving concrete cracks up to 0.40 mm (0.016 in),
- Improved durability and service life,
- Lower construction costs compared to traditional types of waterproofing,
- Potentially eliminates the risk of damage to traditional types of waterproofing systems during the construction process.
Usage
SikaControl®-245 WT Liquid is designed for use in various watertight concrete applications including but not limited to the following structures: Industrial Applications:- Tunnels and Subway Stations
- Manholes
- Bridges
- Water Treatment Plants and Water Tanks
- Dams and Reservoirs
- Secondary Containment Structures
- Shopping Centers
- Libraries
- Data Centers and Computer and Server Rooms
- Elevator Pits
- Basements
- Water Parks
- Underground Parking Garages
- Foundations and Concrete Basements
- Swimming Pools
Advantages
SikaControl®-245 WT Liquid uses a unique combination of active ingredients which react with ingress moisture within concrete. This reaction forms insoluble compounds throughout the capillary system in the concrete matrix resulting in crack healing properties and an improved resistance to water permeability. Additionally, SikaControl®-245 WT Liquid has minimal to negligible impact on setting and strength characteristics. SikaControl®-245 WT Liquid also provides the following benefits:- Uniform permeability reduction throughout the treated concrete volume,
- Improved resistance against hydrostatic pressure,
- Ability to seal non-moving concrete cracks up to 0.40 mm (0.016 in),
- Improved durability and service life,
- Lower construction costs compared to traditional types of waterproofing,
- Potentially eliminates the risk of damage to traditional types of waterproofing systems during the construction process.

Product Details
ENVIRONMENTAL INFORMATION
Potentially eliminates need for post-placement applied barrier, compressing the construction schedule and associated carbon footprint. Extends service life.
A Manufacturer Inventory will be available for SikaControl®-245 WT Liquid.
Shelf Life
Shelf life when stored in original packaging in dry warehouse conditions between 5°C and 27°C (40°F and 80°F) is one year from the date of manufacture. Presence of precipitation or sedimentation is possible over time and does not effect the performance of the product.
Storage Conditions
SikaControl®-245 WT Liquid should be stored above 5°C (40°F). If frozen, thaw and agitate thoroughly to return to a normal state. Protect from direct sunlight.
Specific Gravity
Approx. 1.130
Application
Mixing
Measure the required quantity manually or by automated dispenser. Add SikaControl®-245 WT Liquid directly into the freshly mixed concrete, or as an integral material in the batching cycle. Do NOT mix with dry cement. SikaControl®-245 WT Liquid may be dispensed on-site directly prior to placement. Care must be taken to mix thoroughly. When used in combination with other admixtures dispense each admixture separately into the mix.
Compatibility: SikaControl®-245 WT Liquid can be used in combination with other Sika admixtures and can be successfully used in mix designs utilizing supplementary cementitious materials.
Recommended Dosage
The typical dosage rate of SikaControl®-245 WT Liquid is 1% by weight of cement or cementitious materials. The mix water should be reduced by an equivalent amount of SikaControl®-245 WT Liquid used in the concrete. Various factors will affect the dosage rates.
Trial mixes with the actual materials should be conducted to determine the required dosage for optimum performance.
To the extent specialized materials are used, extreme ambient temperatures are encountered, or for other unusual project conditions, dosage rates outside the typical range may be required. For dosage rates outside the typical range, please contact your local Sika representative.
