PENETOSEAL CRYSTALLING WATERPROOFING

DESCRIPTION

Penetoseal is a unique chemical treatment, penetrating into the concrete with capillary effect, which waterproofs and protects concrete in depth.

APPLICATION FIELDS

  • Construction joints
  • Sewage and waste water treatment tanks
  • Structures below the groundwater level and subject to water penetration
  • Tunnels
  • Foundations
  • Concrete pipes
  • Swimming pools
  • Aquariums
  • Manholes
  • Elevator Pits

 

STANDARD

BS-EN 12390-8, BS 1881-122

FEATURES

  • Penetrates deeply and seals concrete’s capillary tracts and shrinkage cracks
  • Becomes an integral part of the concrete
  • Completely effective against high hydrostatic pressure
  • Protects from waterborne corrosive agents
  • Protects concrete and steel rebar from deterioration
  • Seals minor shrinkage and hairline cracks
  • Allows the passage of water vapor from the inside of the structure (the concrete breathes)
  • Easy to apply
  • Approved for use in contact with potable water

TECHNICAL PROPERTIES

Appearance:  Grey powder

Chloride content: according to standard

Temperature of consumption: ≥50C

Effectiveness: 2-3 weeks after operation

DIRECTION FOR USE

The substrate should be clean and sound, free of dust, loose particles, grease, oil and primers from previous membrane systems or bitumen. The surfaces must also have an open capillary system for the penetoseal treatment. The substrate must be prepared by suitable mechanical preparation techniques such as high pressure water jetting, wet sandblasting, wire brushing etc. and properly pre- wetted to a saturated surface dry condition. Spalled concrete should be repaired by cutting out to sound concrete. Cracks, holes and honeycombs must be repaired and patched with penetoseal and silica sand (5:2 by weight) prior to application.

Mixing:

Mix one 40 kg bag with approximately 12 liters of clean water mechanically using a drill and paddle (max. 500 rpm). Do not mix too wet otherwise the mix may crack and spall when drying. Always add powder to water.

Mix until a homogeneous consistency is achieved. Do not rework stiff material by adding more water. Mix sufficient material to use within 30 minutes.

Continuously mix the product during the application, do not dilute and use the hardened mixture.

Product should be applied in two layers. Apply penetosealL with a stiff fiber brush. Scrub well into the damp wall filling all pores and finish with final strokes in one direction. Apply the second coat while the first coat is still green, if this is not possible pre- water before application of the second coat. Application should be done first to the wall and then to the floors.

Curing:

Moisture cure penetoseal treated surfaces 3-4 times per day for a period of 2-3 days starting with fine water fog spraying the day following the completion of penetoseal applications and dehydration should be prevented.

STORAGE

The shelf life is 12 months if unopened, stored free from frost, moisture and direct sunlight.

SAFETY

penetoseal is alkaline, use protective gloves. If gets into eyes clean out with water immediately, and contact a physician. Mix in small quantities.
