Faster consolidation
Most settlement completes during construction, not after.
Ground & Infrastructure Solutions
Ground Improvement (PVD) & Soil Reinforcement
Prefabricated vertical drains and reinforcement to accelerate consolidation and strengthen soft ground.
Overview
Prefabricated vertical drains (PVD) shorten drainage paths in soft, saturated soils so consolidation settlement occurs faster. Combined with soil reinforcement such as geosynthetics, they help make weak ground suitable for embankments and infrastructure.
Soft clays hold water and settle slowly under load. Prefabricated vertical drains (PVDs) shorten the drainage path so that settlement finishes in months instead of years, and geosynthetic reinforcement adds tensile strength so embankments can be built safely on weak ground.
- PVD systems for accelerated consolidation
- Soil reinforcement with geosynthetics
- Geotextiles, geogrids and geomembranes
- Suited to soft-ground embankments
Key Benefits
Build on soft ground
Makes weak sites usable without deep excavation.
Strong, stable embankments
Geosynthetic reinforcement improves stability.
Economical alternative
Often cost-effective compared with piling or replacing soft soil.
Where It Is Used
- Road and rail embankments on soft clay
- Port, airport and industrial platforms
- Reclaimed land
- Steep slopes and walls needing reinforcement
How We Work
-
1
Investigate the soft layer
Establish thickness, compressibility and drainage properties.
-
2
Design the system
Choose drain spacing, depth, surcharge and reinforcement layers.
-
3
Install
Drive PVDs on a grid and place the drainage blanket and geosynthetics.
-
4
Monitor settlement
Track settlement and pore pressure to confirm consolidation.
What You Receive
- Ground-improvement design basis
- Installation records
- Settlement and pore-pressure monitoring data
- Completion report
Frequently Asked Questions
How much faster is settlement with PVDs?
It depends on soil and drain spacing; the designer calculates the expected time, often reducing it from years to months.
Do PVDs need a surcharge?
Usually yes. A temporary surcharge helps to complete consolidation on schedule.
