ADVANTAGES

 

LOW INSTALLED COST:
Combined installation and material cost is typically less than half the cost of aggregated drains.
EASY TO HANDLE AND INSTALL:
Lightweight (less than 5 oz / sf), easy to handle sheet drain is placed easily and quickly. No heavy equipment or skilled labor required. Inexpensive to store and transport.
HIGH FLOW CAPACITY:
By design, the flow capacity of thin, lightweight prefabricated drains far exceed that of several feet of stone.
REDUCED EXCAVATION:
Core thickness ranges from 1/4” – 1” and reduce the amount of excavation required to install aggregate systems.
SUPERIOR COLLECTION CAPACITY:
The open area for water collection in prefabricated drains is 65-80% vs. 3-5% in perforated pipe. This allows for faster and higher volume water collection in below grade applications, making prefabricated drains a better and more efficient solution for sub-surface drainage applications.
REDUCED CLOGGING:
Filter fabrics permit high volume water entry while retaining fine soil particles. Filtration properties combined with a large percentage of open area for water collection reduce clogging and the possibility of drainage failure.
PREDICTABLE PERFORMANCE:
Prefabricated drains are engineered to meet uniform and independently verified performance characteristics insuring predictable field performance.
HOLDS REINFORCED SHOTCRETE:
Formed core provides good surface adhesion for shotcrete and other construction materials.
ENHANCES WATERPROOFING:
Polymeric core is impervious to water. Water seepage to structural is minimized and provides extended life expectancy of waterproofing membranes.
CHEMICAL RESISTANT:
Prefabricated drain core and filter fabrics are resistant to all naturally occurring soil properties. Additional product choices are available for unique chemical conditions.
STRONG & DURABLE:
Crush strength of core resists damage during installation. High tear and puncture strength of fabric ensures no damage during normal backfill conditions.
SIMPLE INSPECTION:
Visual inspection of material an installation is easy and less time consuming.
 
 

 

   
 CHIMNEY DRAINS  
 
 
STRENGTH:
The chimney drain polymeric dimpled core functions as a pipe and creates a flow channel for collected water while providing strength to withstand load demands from soil or other surface pressure. Compressive strengths are 9,000 lbs/sq ft or 18,000 lbs/sq ft.
 
FLOW:
The core height for chimney drains are 0.25 inches or 0.44 inches and determines the amount of water that can be collected and transported. The flow capacity of the core ranges from 9 to 21 gpm per ft of width which is equivalent to the flow rate found in 4-8 feet of drainage stone.
 
FILTRATION:
The filter fabric prevents the intrusion of soil particles into the drainage core. The geosynthetic filter fabric provides a large open area, creating a more efficient means of water collection in sub-surface drainage applications. Water can quickly enter the drainage core with reduced clogging. The fabric is securely wrapped around the polymeric core to prevent soil intrusion into the flow channel. 
 
Chimney Drains are constructed with a wide range of filter fabrics choices to address the most challenging soil conditions. Chimney drains are available with filter fabrics meeting AASHTO M 288-06 specification for geotextile survivability classifications from installation stresses in subsurface drainage applications
