Vertical drainage systems are a proven solution for accelerating the consolidation process of loose soils. To maximize your vertical drainage system’s efficiency and functionality, use strip drains as your horizontal drainage solution at the surface to evacuate the water from the building pad.
A vertical drainage system, also commonly referred to as wick drains, aims to draw or wick the water in the soil to the surface to speed up the settlement process. Depending on how porous the type of soil will determine the grid pattern and spacing of the vertical drain as well the time necessary to complete the settlement process. The timeframe for the settlement process to occur is known as the consolidation period. Vertical drainage systems shorten the consolidation process by transporting, or wicking, water from the soil to dedicated drainage areas.
Vertical wick drains are prefabricated geotextile filter-wrapped plastic strips with grooved channels. The filter wraps prevent soil and debris from entering the drain, resulting in constant flow rates for the entering water.
To create the most dependable and efficient drainage, a drainage path must be provided to receive this water and conduct it from under the surcharge to designated drainage areas. This drainage system must perform without applying excessive back-pressure to the vertical drains, causing delays in the consolidation process. Traditionally, layers of sand or gravel are installed above the horizontal drainage system in a process known as surcharging. The best solution is to install a strip drain as your flat drain path to receive inflow from the vertical drainage system. Strip drains can reduce and often eliminate the need to use the granular layer.
Vertical drainage systems are a proven method that has been applied in a variety of construction sites. Prefabricated vertical wick drains are most commonly used as a ground improvement method in commercial, civil, and industrial applications, such as:
- Mining areas
- Dredging and land reclamation
- Flood protection
- Retail Developments
- Tank farms
When comparing strip drains to alternative drainage systems, it is clear that strip drains are the most beneficial. French drains and traditional pipe systems are not as effective, durable, or reliable as strip drains and are often more expensive to install. One of the most glaring advantages strip drains offer is their superior water intake or inflow rate. Strip drains can move a much higher volume of water when compared to other systems.
The open surface area of the strip drain core allows for faster permeability of groundwater into the drain, while the geosynthetic filtration ensures the system will remain free flowing. As long as you install the proper size strip drain, clogs are virtually impossible. They are designed to prevent soil and other debris from entering. The highest quality strip drains have a 0% failure rate.
Strip drains also benefit worksites by being easier to install than French drains or other traditional linear drains. The narrow trenches strip drains are installed to require little ground disturbance, and no extra layers of gravel or sand are needed. High quality strip drains are easily installed. As the product is unrolled, there is zero memory to the coil, as found with traditional drain tile, making it much easier to work with. The simplified installation also translates into cost savings. Fewer labor hours and workers are required to install strip drains.
