Fluids used in the hydraulic fracturing (fracking) process that are returned to the surface, called flowback, are generally stored in open pits (ponds) or tanks at the well site prior to disposal. Flowback – water combined with sand, sediment, oil and other additives – must be contained to ensure it does not permeate into the ground. Frac water ponds are typically lined with a geomembrane to help prevent any seepage or leaks.

Nilex can custom fabricate frac pond liners to any size. Nilex geomembranes are designed to withstand the contaminants contained in the flowback and are highly puncture resistant.


This latest innovation in geomembrane liner technology is the patent pending HLR (Hot Liquid Rated) Series of geomembrane liners. With its unique blend of special resins and additive package, this series of hot liquid resistant (high temperature) geomembrane liners offers the same hydrostatic...

Enviroflex linear low density polyethylene (LLDPE) geomembranes provide much of the same durability and resistance properties found in high density polyethylene (HDPE) geomembranes, but with the added benefit of increased material flexibility because it is a lower-density polymer. This gives...


The customer, Harber Coatings, specializes in protecting industrial parts against corrosion and abrasion. Their coating process involves the use of dip tanks that contain a solution of nickel, phosphorus, or hydrochloric acid. During a recent inspection, the tanks themselves showed signs of…
