|
| When constructing bridge abutments, impermeable soil layers can trap water and create hyprdrostatic pressure against the structural wall. Saturated soils, excessive water run-off from road surfaces and freeze / thaw cycles in colder climates make proper drainage a critical design consideration. |
| |
|
| Improper drainage design can compromise the structure by creating leaks that require expensive repairs and/or maintenance. When proper drainage is unavailable, the wall must be designed to handle heavier loads, resulting in higher construction costs. Vertical drainage using stone is not a practical or efficient long term solution due to installation challenges and long term soil fines that can eventually clog the stone. |
| Prefabricated drains provide high performance drainage solutions for concrete structures by providing a positive and rapid evacuation of subsurface ground water before the accumulated hydrostatic pressure can compromise the structure. |
| |
|
Constructed with a molded high impact polystyrene core with a bonded filter fabric, sheet drains provide a sustainable, cost effective design that reduces the need for expensive repairs.
|
| |
| Prefabricated drains are sustainable,low-profile, lightweight products that provide superior collection and provide flow capacities that far exceeds that of several feet of aggregate. |
 . |
|
is designed for single-sided drainage applications that require high compressive strength and high flow capacity. |

|
|
 |
|
functions as a direct replacement to costly perforated pipe and stone systems.
By design, is equipped to handle the high volume of water generated by sheet drains more efficiently. |

SITEDRAIN & AASHTO M 288-06
 |
| |
| drainage products incorporate critical design considerations into a versatile and expanded product line. Specially designed drainage cores that address strength and flow requirements are combined with geotextiles meeting AASHTO M 288-06 survivability classifications for subsurface drainage. This allows design professionals the flexibility to factor in the many site variables that are critical to per-formance based on specific conditions.
