07494648998 Website

Application

Provides protection against:

  • Water penetration.
  • H2S and microbially induced corrosion (MIC).
  • Acidic waters.
  • Sulfate attack.
  • Salts/ chlorides and corrosion.
  • Alkali silica reaction (ASR).


Can be used on:

  • Wastewater structures.
  • Pipes, manholes and pump stations.
  • Pre-cast concrete.
  • Sewers.
  • Lift stations.
  • Drop structures.

Description

An advanced chemical admixture based on Krystol waterproofing agents and special additives, that is designed to protect concrete from the harsh and destructive conditions present in sewer and wastewater environments containing hydrogen sulfide.


Features and benefits:

  • The concrete is better able to resist the corrosive sewer environment, adding years to the concrete’s service life and eliminating costly maintenance.
  • Does not leach from the concrete, and will not be consumed or overwhelmed by bio-film in a sewer environment.
  • Resists hydrostatic pressure, infiltration and exfiltration in pipes.
  • Seals and heals cracks and micro-cracks.
  • Permanent integral protection - impervious to scrapes or punctures.
  • Easily added to concrete at the time of batching - no installation labor.
  • Replaces costly membranes and liners for wastewater pipes or tanks.
  • Pesticide-free.


Performance requirements:

  • Bio-acid resistance – Treated samples retained 85% better toughness after bio-acid attack compared to untreated samples measured by load deflection testing.
  • Acid resistance – Weight loss reduced > 50% with exposure to 5% sulfuric acid solution. 
  • Water permeability – Reduced up to 97%.
  • Crack sealing – up to 0.5 mm.
  • Crack healing – Improved compressive strength recovery. 
  • Sulfate resistance – Greater than control (no strength loss).
  • Drying shrinkage – Reduced up to 25%.
  • Cracking – Reduced crack widths up to 53%.  
  • Freeze-Thaw – Reduced up to 87%.
  • ASR – Reduced ASR expansion.
  • VOC – Zero.
