Capillary Break under Pavement

Application Overview

Moisture intrusion from capillary rise and fluctuating groundwater levels is a major cause of weakened pavement foundations. POME’s engineered capillary break systems use high-performance geocomposite drainage layers that have been rigorously tested for flow capacity, compressive strength, and long-term durability. These systems provide a reliable, engineered barrier that maintains a dry and stable subgrade, improving pavement life and performance.

Challenges in Pavement Subgrade Stability

Capillary Rise
Fine-grained soils draw water upward, reducing bearing capacity and accelerating pavement deterioration.
Moisture Sensitivity
Wet subgrades lead to rutting, pumping, and premature structural failure.
Seasonal Water Table Fluctuations
Variable moisture conditions introduce differential settlement and pavement distortion.
Inefficient Traditional Methods
Thick granular layers are costly and offer inconsistent performance and require significant excavation.

POME’s Solution

High-Performance Geocomposite Drainage Systems
Develops engineered capillary break solutions using advanced geocomposite drains tested for flow efficiency, compressive strength, and long-term durability.
Effective Moisture Barrier Against Capillary Rise
Creates a consistent moisture break that prevents upward water migration, maintaining stable and dry subgrade conditions beneath pavements.
Thin, Predictable Alternative to Granular Layers
Replaces thick granular drainage layers with a thin, uniform system engineered to deliver reliable and predictable hydraulic performance.
Improved Subgrade Stability and Reduced Settlement Risk
Minimizes moisture fluctuations in fine-grained and weak soils, enhancing subgrade stability and significantly reducing the risk of long-term settlement.
