SWS®
EARTH CONTACT BACKFILL

Loresco type SWS is specially formulated for impressed current surface systems.

 
 
Loresco type SWS is designed for use in impressed current surface systems. SWS is also suitable for containerized anode systems and semi-deep impressed current systems. SWS may be poured dry or through water or light mud.

Loresco SWS exhibits a hard, round shape and does not require tamping because of its ability to go full density with simple pouring. The bulk density of SWS is 68 lbs. per cubic foot. The predominant particle sizing ranges from 1mm to 5mm with no particle larger than 12mm.

The manufacture of SWS is in a highly controlled "hot" atmosphere which produces a particle surface with wettable characteristics. This allows SWS to be freely poured directly into water or light mud without sacrificing system integrity due to poorly compacted carbon. Set-up time is almost instantaneous.

Loresco SWS is a product designed to be placed in the earth. According to EPA-approved leacherate tests, SWS meets all purity requirements for materials utilized in underground burial.

Installation:
Loresco SWS may be poured freely in dry applications. If SWS is poured through water, the rate should not exceed one hundred pounds per minute. The rate of pouring should be decreased if the fluid is a light mud.

Horizontal Installation Procedure:

bulletHave a reasonably clean ditch (design usually calls for a ditch one foot wide).
bulletPour Loresco SWS in a continuous layer six inches deep (or as specified).
bulletPlace anodes on top of SWS.
bulletPour SWS in a continuous layer until anodes are covered by a six inch backfill cover (or as specified).
bulletFill the remainder of the ditch as specified.

Vertical Installation Procedure:

bulletHave a reasonably clean hole (depth depending on soil resistivity).
bulletPlace one foot of SWS in bottom of hole.
bulletLower and center anode in proper position.
bulletPour SWS over anode until design level is reached.
bulletFill remainder of hole as design specifies.

Specifications:

bulletBulk Density: 68 lbs. per cubic foot.
bulletParticle Sizing: Ranging from 1 mm to 12 mm (90% between 1 mm and 5 mm)

Shipping:
Loresco SWS is shipped in 50-pound plastic-lined multi-wall paper bags. Pallets are available with 45 bags per pallet. Proven export packaging is available.
