  • Essential for reparation of pavement, concrete roads, ramps, surface treatment of roads, new constructions, etc.
  • As a modifier additive for hydraulic anchoring, it acts as a binder, improving the waterproof effect of the system and confering better hydraulic properties such as a greater adherence.
  • PREPARATION OF THE SURFACE: supports must be clean and exent of wrongly attached parts. Moisten with water beforehand. 
  • AS BONDING: apply using a brush or a roller. Do not let dry before applying the mortar. For works of high performance, it is recommended making a grout of CC308, concrete, gravel and water. Knead and apply with brush. Do not let dry before applying the mortar or concrete.

  • AS ADDITIVE: mix CC308 with water at a rate of 1:4 depending on the required resistance.
  • High performance due to its low dosage
  • Effectiveness: enhances resistance of mortar against flexion and compression and reduces risk of fissure while hardening
  • Multi-action: promotes adherence, improves resistances and lowers fissure risks
  • Safe to use: not classified as hazardous
  • Environmental improvement: biodegradable product
  • Other benefits: enhances resistance against abrasion and favours water-resistance of mortars
