Most HDD contractors know the frustration of the paint filter test. Landfills, in order to accept drilling waste or spoils, put a sample of the material on a paint filter for five minutes. If any portion of the material passes through the filter in that test period, the material is deemed to have free liquids. Of course, landfills can then reject the whole truck or require premium disposal fees.
Our company advised horizontal directional drilling specialist Brotherton Pipeline Inc., a registered minority company out of Gold Hill, Oregon, on one solution for this issue. Brotherton has over 30 years of experience in natural gas transmission and distribution, plowing, trenching, vacuum excavation, auger boring, rock hammer boring and underground power installation. The company (like every HDD contractor) has always found drill spoils a challenge. Its crews work throughout the western and northwestern U.S. on a variety of projects, including crossings for highways, creeks, rivers, streets, wetlands, canals, railroads and lava fields, as well as beach approaches. We recommended and they have come to rely on our Slurrybond 2000 G, one of several spoils solidification products on the market.
