Enka®Break

Capillary Break Layer

Geosynthetic capillary break layers are used to replace the more traditional  sandy gravel or gravel capillary break layers in embankment bases and pavement structures

EnkaBreak is a geocomposite that can be applied as horizontal capillary breaker under infrastructural embankments, parking areas or any pavements located in areas with high groundwater conditions. It is installed just above the highest level of the water table ensuring the capillary void is never totally saturated by groundwater.

EnkaBreak provides an effective horizontal capillary barrier by creating a continuous spacing layer which prevents moisture to rise.

Based on several academic resources it can be stated that the most effective capillary break method is by creating a durable spacer between the saturated subsoil and the embankment structure.

EnkaBreak replaces expensive thick granular layers and so reduces the amount of excavation and required new raw materials. The use of EnkaBreak will result in less construction time, lower maintenance intervals and an improved expected lifespan of the project. EnkaBreak additionally contributes to lowering CO2 emissions.

Benefits of using EnkaBreak geosynthetic capillary break layer
  • Reduce the negative impact of high and differential groundwater conditions
  • Reduce amount of excavation and supply of new raw material
  • Improved lifespan and maintenance interval
  • Replace expensive thick granular layers for capillary break function
  • Reduce construction time
  • Lower CO2 (carbon dioxide) emissions
Application Areas
  • Infrastructural embankments
  • Parking areas with high groundwater conditions
  • Pavement structures 
  • High embankments (>2m)
  • Low embankments (eg: polder wetlands with low height embankments)
