Sika® WT-110 P

WATERTIGHT/SUPERPLASTICING (HRWR) CONCRETE ADMIXTURE

Sika® WT-110 P is a combined watertight/superplasticising (HRWR) concrete admixture, used to enhance the workability of and reduce the water permeability of concrete. The product incorporates Sika® ViscoCrete superplasticiser technology and hydrophobic agent and depending on material package will produce watertight concrete at a S3 consistence with a w/c ratio of < 0.45 without the addition of a separate superplasticiser (HRWR).

Sika® WT-110 P has the following characteristics and benefits:
  • Strong water reductions, resulting in higher density, durability and strength.
  • Incorporation of hydrophobic agent to reduce water penetration under hydrostatic pressure and water absorption.
  • Sika® WT-110 P improves resistance to vapour transmission.
  • In combination with a Sika® ViscoCrete® Superplasticiser (HRWR) admixture, SCC can be produced.
  • Packaged in a water soluble bag for ease of dosage.

  • Basements
  • Parking garages
  • Utility/plant rooms
 
  • Tunnels
  • Swimming pools
  • Water retaining structures
  • Dams
  • Waste water treatment structures

Technical Information

Concrete mix design

  • Sika® WT-110 P has been formulated for use in concrete with a medium to high workability (> S3 Consistence) with a minimum cementitious content of 350 kg/m3 and a maximum water/cementitious ratio of 0.45.
  • Concrete containing Sika® WT-110 P should have a maximum SCM of not more than 25 %.
  • Sika® WT-110 P has been specifically formulated to produced a S3 consistence with a w/c ratio of < 0.45 at 350 kg/m3 cementitious without the addition of a separate superplasticer (HRWR).
  • Subject to material package and cement content water reductions of between typically 10 - 15 % can be achieved. Laboratory trials are always recommended to evaluate and confirm actual water reduction.
  • Should the addition of a Superplasticiser (HRWR) admixture be required to achieve a w/c ratio of < 0.45 a Sika® Viscocrete® (WR) admixture is to selected to ensure compatibility.

Compatibility

Sika® WT-110 P is compatible with many Sika products.

  • Sika® ViscoCrete® (WR) admixtures
  • Concrete containing Sika® WT-110 P should have a maximum SCM of not more than 25 %

Important: Always conduct trials before combining products in specific mixes and contact our Technical Service Department for information and advice about any specific combination

DISPENSING

  • Forced action and truck mixers should be free from all contaminants prior to the batching of concrete containing Sika® WT-110 P.
  • Sika® WT-110 P should be added to the mixer at the recommended dose (1 bag per m3) prior to the batching of concrete.
  • Batched concrete mix constituents should be subsequently batched on to the Sika® WT-110 P in accordance with Sika® mix design recommendations.
  • Additional mixing water should then be dispensed to bring the concrete to the desired consistence.

 
  • On completion of the batching procedure the concrete load should be mixed in the truck mixer/agitator on full revolutions for a minimum of 5 minutes to ensure that the optimum consistence has been achieved.
  • The w/c ratio and consistence control remains the responsibility of the concrete producer. Laboratory trials are recommended to evaluate and confirm the actual water reduction.

In the event of a part load (< 1.0 m3) it is recommended that 1 bag of Sika® WT-110 P is used.
