Geomembrane Liner Installation
Geomembrane liners are impermeable membrane materials installed to prevent liquids from migrating through soil or containment structures. In civil and environmental engineering, they are used in applications ranging from water storage and stormwater management to hazardous material containment and landfill construction. Exact Stormwater Management has been installing and repairing geomembrane liner systems throughout the Southeast since 1992, working with a wide range of materials including HDPE, LLDPE, PVC, RPP, RPE, and XR-5 in thicknesses from 10 mil to 100 mil. If you need a geomembrane liner installed, repaired, or replaced, contact us for a project consultation.
Pond and Lake Liners
Pond and lake liners are among the most common geomembrane liner applications. They are used to retain water in irrigation ponds, retention ponds, decorative water features, golf course water hazards, and aquaculture facilities. Without a liner, water loss through seepage can make these water features impractical or impossible to maintain. Exact Stormwater Management installs pond liners for residential, commercial, agricultural, and municipal clients throughout the Southeast.
Material selection depends on the application, water chemistry, UV exposure, and long-term maintenance requirements. We commonly install 30 mil PVC, HDPE, LLDPE, RPP, RPE, and XR-5 pond liners, selecting the appropriate material based on your site conditions and budget. With experience in pond liner installation dating back to 1992, we have the expertise to recommend the right liner system and install it correctly the first time.
Underground Detention and Cisterns
Geomembrane liners are a critical component of underground detention systems and cisterns. Whether the goal is stormwater harvesting for reuse or groundwater exclusion to protect infrastructure, a properly installed liner prevents leakage and ensures long-term system performance. Liners are used in modular underground detention systems, concrete cisterns, and precast vaults throughout residential, commercial, and municipal projects.
Exact Stormwater Management has extensive experience lining underground detention and cistern systems across the Southeast. We work with project engineers and contractors to select the appropriate liner material and ensure the installation meets design specifications.

Bioretention Facility, Biofilter, Dry Swale
Bioretention facilities, biofilters, rain gardens, dry swales, and compost-amended grass swales are semi-natural stormwater treatment systems designed to filter runoff before it reaches streams and waterways. Many of these systems require a low-permeability liner at their base to control infiltration rates, prevent groundwater contamination, or meet the design requirements of a specific permit or engineering specification.
Exact Stormwater Management installs geomembrane liners in bioretention systems and biofilters throughout the Southeast. We work as both a prime contractor installing the full system and as a subcontractor handling the liner installation within a larger project. Whether liner installation is a standalone scope or part of a turnkey build, we ensure the liner is installed correctly for critical applications where leaking is not acceptable.
Secondary Containment Liners
Secondary containment liners are required under EPA Spill Prevention, Control, and Countermeasure (SPCC) regulations for facilities that store oil or hazardous materials in above-ground storage tanks (ASTs). The liner creates an impermeable barrier inside the containment berms or dikes, ensuring that any tank failure or spill does not reach the soil, groundwater, or surrounding waterways. Proper secondary containment is not only an environmental obligation but a legal one for many facilities.
Exact Stormwater Management installs secondary containment liners for fuel terminals, industrial facilities, and utility sites across the Southeast. We commonly use XR-5 and HDPE liners for these applications due to their chemical resistance and long service life. Our crews are experienced working within active industrial environments and meeting the specific design and inspection requirements associated with SPCC-regulated secondary containment systems.
Geomembrane Liner Repairs and Rehabilitation
All geomembrane liner systems experience stress and wear over time from UV exposure, mechanical loading, chemical contact, and freeze-thaw cycles. Liner damage can include punctures, tears, seam failures, and UV degradation. In many cases, a targeted repair or partial replacement is a cost-effective alternative to full liner removal and reinstallation, extending the functional life of the system by years or decades.
Exact Stormwater Management performs geomembrane liner repairs and rehabilitation on landfills, lagoons, secondary containment systems, stormwater basins, and other lined structures. We locate damaged areas, prepare the liner surface, and apply patching or welding techniques appropriate to the liner material. When repair is no longer sufficient, we also perform full liner replacements to restore containment integrity.
