Parex CS Grout

Non-shrink, high strength, versatile (consistency can be adjusted), high flow, cementitious grout

Parex CS Grout is a Portland cement based product giving high strength, high flow and non-shrink properties. By adjusting the water content, different consistencies (liquid, plastic and mortar) can be achieved. Placed grout gives structural support and good vibration resistance.

  • High strength.
  • High flow at the maximum permissible water content. 
  • Non-shrink.
  • 'Chloride-free' (<0.05%).
  • Low water absorbtion.
  • Resistance to sea water and mild alkali attack.
  • Excellent flow characteristics.
  • Pumpable.
  • Adjustable water content for varying applications.

Application steps

MIXING

Pour 4.5 litres of clean water into the mixing vessel for each complete 25 kg bag of Parex CS Grout to be used. Slowly add the powder to the water whilst continually mixing. Mechanical mixing should be carried out using either a high torque slow speed drill with a grout stirrer, or a grout mixer set on slow speed (high speed or colloidal mixing will cause thixotropy, leading to loss of flow). 

Varying consistencies are achievable using the following water contents per 25 kg bag:

Mortar

3.6 litres

Plastic

4.3 litres

Liquid

4.8 litres

APPLICATION

Grout should be placed within 20 minutes of mixing. Continuous placing is important, pouring from one side of the formwork until the grout appears at the opposite side of the grouting area. Do not disturb once grouting has been completed.  

CURING TREATMENT

Placed grout, which is exposed, should be cured in accordance with good concrete practice, including water spray or by using Sikafloor® ProSeal. In cold weather, apply heat blankets to maintain a constant temperature.

CLEANING OF EQUIPMENT

Clean all tools and application equipment with water immediately after use. Hardened / cured material can only be mechanically removed.
