DrainGel™ is a highly-concentrated gel which clings to the sides of drains and pipes. DrainGel™ can also be easily sprayed into cracks and crevices and onto hard-to-access non-drain sites. DrainGel™'s formulation incorporates specialized microorganisms in combination with biological support ingredients and essential growth factors. This unique formulation promotes improved performance in degradation of organic materials in both aerobic and anaerobic environments. DrainGel™ is also specifically designed to block the production of odors frequently occurring in drain lines, sewer lines and grease traps.
