Description

Features:

  • RIW Cementseal is polymer modified to give excellent adhesion and abrasion resistance.
  • Dense matrix offers low permeability to water, even at 10 bar pressure.
  • Totally waterproof and will also resist negative water pressure.
  • Gives enhanced resistance to carbonation.
  • Will readily accept flooring and other decorative finishes.
  • Materials are pre-packaged and only require mixing on site to give a slurry, which can then be easily applied by brush, squeegee or spray.
  • Non-toxic when cured.
  • CE marked.

Substrate:

  • The areas to be treated must be free from all unsound material, e.g. dust, oil, grease, corrosion by-products and organic growth.
  • The strength of the concrete sub-base should be a minimum of 20 N/ mm².
  • Deck or floor areas should be primed with RIW Cementseal Primer.

Application temperature:

5–35°C.

Curing:

Protect the mortar from strong sunlight and drying winds with RIW Cementseal Primer, polythene sheeting, damp hessian or similar.

Usage:

  • Designed to be used to prevent water ingress into basements, cellars and other below ground structures.
  • It can also be used for temporary waterproofing in new construction, to protect from water ingress prior to weatherproofing of the structure.

Product Options

Primer/ curing agent:

- RIW Cementseal Primer:

  • An environmentally friendly, multi-functional water based compound, formulated on an aqueous acrylic copolymer.
  • The product chemically reacts with cement, to produce a durable surface seal, which stabilises the substrate and reduces the evaporation of water.
  • Provides efficient sealing of horizontal concrete substrates, by stabilising the surface and preventing out-gassing, prior to the application of RIW Cementseal.
  • The product will also act as a curing agent for newly placed cementitious mortars and coatings, by helping to reduce the amount of water evaporating from the surface.
  • The primer is also used when applying joint tape.

Joint tape:

- RIW Cementjoint:

  • An advanced, elastomeric, highly tear resistant, breathable, waterproof composite tape.
  • Permanently elastomeric composite membrane embedded in backing fabric, exhibiting over 600% elongation.
  • Impermeable to water under 10 bar hydrostatic pressure, yet allows the free passage of water vapour.
  • Good UV and weathering resistance and highly resistant to a wide range of chemicals.
  • When embedded in RIW Cementflex, it gives a highly flexible, impermeable seal over ‘live’ cracks and expansion/ construction joints.
