In a residential neighborhood built on sandy loam soils, a resident had a new retaining wall installed to improve her property’s boundary. Just after the construction was finished a sink hole appeared below the new retaining wall. This hole was covered and compacted but because of the poor soils of the area the hole reappeared adjacent to the first hole and the retaining wall.
To ensure that this ongoing problem didn’t continue a Filtrexx Channel™ was constructed to move a concentrated rain water flow from a neighbors yard to an area where it could be dispersed into a sheet flow area. The Filtrexx Channel Soxx™ was vegetated with fescue an d rye grass. The sink holes have not reappeared since the channel was installed.
