SikaControl®-739

(former MasterPel® 739)

A LOW DOSAGE HYDROPHOBIC PORE-BLOCKING ADMIXTURE FOR WATER RESISTANT CONCRETE AND MORTAR

SikaControl®-739 is a hydrophobic pore-blocking ingredient (H.P.I) which imparts water resisting properties for concrete / mortar. It reduces water absorption and water permeability of concrete significantly and enhances durability of concrete.
SikaControl®-739 is a chloride free organic admixture. It reacts with the cement hydration products to form a hydrophobic ingredient to reduce the capillary suction and prevent the ingress of water / potentially deleterious soluble material.

  • Very low absorption – Increased durability and water tightness
  • Very low water permeability – Favourable values indicate imperviousness
  • Integral system – Protection is maintained throughout the concrete matrix
  • Ammonia free – Environment friendly. Fully compatible with certain surface coating and finishes

Usage

SikaControl®-739 is suitable for any concrete structure, which requires watertightness, such as:
  • Basement walls / floors, Underground car parks
  • Tunnels / underpass / airport or station buildings
  • Foundations, piles and pile caps
  • Water retaining structures, swimming pool, water
  • tanks, reservoirs, water towers
  • Land drainage, manholes
  • Reinforced concrete in marine environment subject to tidal and wet/dry cycling
  • Waste water treatment and desalination plant
 

Advantages

  • Very low absorption – Increased durability and water tightness
  • Very low water permeability – Favourable values indicate imperviousness
  • Integral system – Protection is maintained throughout the concrete matrix
  • Ammonia free – Environment friendly. Fully compatible with certain surface coating and finishes

Technical Information

Curing Conditions

Like all cementitious product, concrete made with SikaControl®-739 must be protected against rapid drying due to high temperature and/or strong wind. The use of wet burlap, plastic sheets or a curing compound is highly recommended.

Application

Application Information

Dispensing

SikaControl®-739 should be added separately to the initial batching water to ensure complete distribution throughout the mix. Do not use seawater, bore water or water containing a high dissolved mineral of content, for mixing concrete.
