Drainage

Drainage composites play an important role in building envelope protection. Above-grade drainage panels help channel water away toward drains to eliminate build up. Below-grade drainage panels help serve a number of purposes: One, they help divert water away from the structure to designated discharge points. Two, they help protect the waterproofing system from additional damage. Three, drainage strips can help collect and expel methane gas and other contaminants from underneath structures. EPRO provides a wide variety of drainage composites to address a number of different conditions.

e.drain

e.drain has been specifically designed to meet the drainage and protection requirements of below-grade waterproofing applications. E.Series utilizes e.drain in applications for over-excavated, below-grade foundation walls to effectively eliminate the buildup of nuisance water, provide another layer of waterproofing redundancy and provide protection during backfill. e.drain is also applied to shoring as a base course for E.spray.

When concrete is applied, the e.drain and e.spray become integrated into the below-grade foundation walls, forming a uniform composite system that directs water away and provides a seamless waterproofing membrane.

e.drain features a lightweight, three-dimensional, highly flexible, high-density polyethylene (HDPE) core and a polypropylene geotextile filter fabric. The filter fabric is bonded to the dimples of the HDPE core. e.drain benefits include:

  • High-density polyethylene core provides a high level of chemical resistance and performs as a waterproofing barrier.
  • Unique shallow dimple design allows for a uniform application of e.spray.
  • For shoring applications, e.drain allows waterproofing to become fully integrated into and bonded to the building foundation wall.
  • Variable widths (6’ and 8’) provide minimal overlapping of seams and increase installation efficiency.
  • Suitable for both cast-in-place concrete and shotcrete.

e.drain 6000

e.drain 6000 is applied in negative-side applications to blindside shoring walls, in positive-side applications to over-excavated walls and over plaza decks. e.drain 6000 prefabricated drainage composite is designed to protect the E.Series system assembly while effectively eliminating the buildup and ponding of water against the membrane assembly.

e.drain 6000 features a lightweight, three dimensional, high-compressive strength polypropylene core and bonded non-woven geotextile fabric. The bonded filter fabric allows water to pass freely into the molded drain while preventing soil particles from entering and clogging the core structure. e.drain 6000 benefits include:

  • Provides extremely high compressive strength to meet a wide variety of project conditions.
  • Polypropylene provides greater chemical resistance than traditional polystyrene.
  • Maintains flexibility in freezing temperatures.

e.drain 6200

e.drain 6200 is applied in positive-side applications to over-excavated walls and over plaza decks. e.drain 6000 prefabricated drainage composite is designed to protect the E.Series system assembly while effectively eliminating the buildup and ponding of water against the membrane assembly. Unlike e.drain 6000, e.drain 6200 contains a plastic backing film to provide additional waterproofing system protection when necessary.

e.drain 6200 features a lightweight, three dimensional, high-compressive strength polypropylene core and bonded non-woven geotextile fabric. The bonded filter fabric allows water to pass freely into the molded drain while preventing soil particles from entering and clogging the core structure. e.drain 6200 benefits include:

  • Contains a protective plastic film on the backside of the drainage composite.
  • Provides extremely high compressive strength to meet a wide variety of project conditions.
  • Polypropylene provides greater chemical resistance than traditional polystyrene.
  • Maintains flexibility in freezing temperatures.

e.drain 9000

e.drain 9000 is applied in horizontal above-grade waterproofing applications over plaza decks, planters, green roofs and balconies. e.drain 9000 prefabricated drainage composite is designed to protect the E.Series system assembly while effectively eliminating the buildup and ponding of water against the membrane assembly.

e.drain 9000 features a lightweight, three dimensional, high-compressive strength polypropylene core and bonded woven geotextile fabric. The bonded filter fabric allows water to pass freely into the molded drain while preventing soil particles from entering and clogging the core structure. e.drain 9000 benefits include:

  • Provides extremely high compressive strength to meet a wide variety of project conditions.
  • Woven geotextile retains soil and sand while allowing filtered water to pass into the drainage core.
  • Maintains flexibility in freezing temperatures.

e.drain 12ds

e.drain 12ds has been specifically designed for installation along the base of below-grade foundation walls to enhance the removal of water away from the building to the specified discharge points.

e.drain 12ds features a lightweight three-dimensional, highly flexible polypropylene core and a non-woven geotextile filter fabric. The filter fabric is bonded to the dimples of the polypropylene core to prevent clogging within the drain. e.drain 12ds benefits include:

  • Cost-effective alternative to traditional pip and gravel French drains.
  • Exceptional flow rates.
  • Excellent compressive strength.
  • Installation can occur in any weather condition.

e.vent

e.vent is a composite low profile pressure relief and collection system designed to mitigate the build up of methane gas and contaminated vapor under an overlying structure. e.vent is most commonly designed to operate passively, but may also be designed as an active system when conditions require.

e.vent features a lightweight, three-dimensional, highly flexible polypropylene core and a non-woven geotextile filter fabric. The filter fabric is bonded to the polypropylene core to prevent fine substrates, such as sand, from clogging the vent pipe. e.vent benefits include:

  • Cost-effective alternative to traditional trenched PVC or ADS pipe systems.
  • Placed directly below the barrier system to drastically reduce vapor accumulation under the structure.
  • Can operate as a passive system with the ability to activate in the future.
Note that e.vent is not effective when constantly submerged, and it should be placed within a permeable substrate.
