Heavy-gauge, durable, recyclable and reusable HDPE liner system for all primary and secondary containment needs

SiteSaver is a strategically designed and comprehensive drill pad or construction site lining system that consists of thermoformed HDPE ribbed base sections, berms, and corner pieces. They are joined through an electro-fusion process to create virtually any size protective liner. Designed and manufactured by Penda, the nation’s #1 heavy gauge thermoformer, SiteSaver’s quality and product performance is backed by more than 60 years of plastics engineering leadership, product development and manufacturing excellence:

  • 100% recyclability
  • Reusable
  • Electrofusion for leak resistant performance
  • High resistance to acidic or alkaline soils and chemicals
  • Flexibility that makes installation fast and easy with minimal environmental disturbance
  • Low maintenance costs
  • Quality that meets ISO 900 and ISO 14001 standards



Perhaps the Most Effective Primary Containment Liner on the Market

Primary Containment is the most important preventative measure against potential spills of petrochemicals, frack water and other hazardous liquids.

The SiteSaver HDPE lining system has proven to be one of the most effective primary containment solutions for oil and natural gas drilling sites. Made from one of the most durable and corrosion resistant materials on the market, SiteSaver will help avoid the costly expense of liner replacement and maintenance, spill clean-up and government fines. Additionally, it provides:

  • Designed and approved for use to PA Regulations Act 13
  • Made with recycled HDPE & 100% recyclable
  • Installs quickly, removes quickly and can be re-used min three times
  • UV, chemical and weather resistant
  • Puncture/tear resistant with low maintenance
  • Minimize “slip, trip & fall” incidents
  • Provides a safer working environment when used in conjunction with gravel, fibergrates or rigmats
  • No VOCs
  • Collect and direct water or critical fluids
  • Has containment within containment capability – Berms can segregate areas within the primary containment, providing a low cost solution
  • Permanent or temporary
  • Easily transportable



SiteSaver’s secondary containment systems are designed to prevent leaks and from spills that might occur in or around tanks, generators, vehicles, lighttowers, or any other piece of equipment storing biofuel, chemicals, ethanol, oil, gas, diesel fuel and petroleum. SiteSaver berms are easy to install and feature fusible seams for a leak free secondary containment system.

  • Reusable up to 30 times
  • Made from corrosion-resistant, UV protected HDPE
  • Rugged, portable, no folding
  • Can be configured in various shapes and sizes
  • Exceptional chemical resistance
  • Low Maintenance
  • Nestable for transport
  • Environmentally compliant



  • Drilling sites primary containment
  • Drilling sites secondary containment


  • Petro/chemical
  • Pulp and paper
  • Custody transfer stations

SiteSaver has been specifically engineered to be infinitely expandable. Standard SiteSaver floor sections are 6.25′ x 8′. These floor sections can be joined to build a pad to the dimensions of any site.

The SiteSaver is made of HDPE (high density polyethylene), which is very durable and extremely resistant to chemicals and corrosion. Accelerated laboratory tests project a minimum lifespan of up to 50 years. UV stabilizers are also included to inhibit the physical and chemical process of UV-induced degradation. The inherent physical properties of HDPE used to manufacture SiteSaver will also allow it to perform well in both hot and cold environments.

Should damage to SiteSaver occur in the field, patch kits are available for flat portions along the perimeter of individual floor sections (i.e. the non-ribbed portion). Substantially damaged floor sections can be replaced with minimal disturbance to surrounding floor sections. To remove a damaged floor section, simply cut along the inside edge of the welded seam joining the damaged floor section to neighboring floor sections; remove the damaged floor section and replace it with a new one; re-weld the replacement floor section to the neighboring floor sections. Damaged panels can be returned to a SiteSaver Distributor for recycling.

Yes, SiteSaver can be reused multiple times. In fact, disassembling the SiteSaver is even simpler than assembly. To do so, cut the SiteSaver on either side of the welded seam joining floor sections together to break the pad into manageable pieces. The resulting smaller pieces are rolled up, placed on a flatbed trailer and brought to the next site where a new weld is installed and the SiteSaver reassembled.

Note: It is up to the contractor to determine how many floor sections remain assembled together to be rolled based on their equipment capabilities. SiteSaver recommends a maximum of 5 floor sections wide by up to 200′ of floor sections long for ease of loading and transportation.

The individual SiteSaver pieces are laid out and aligned along their perimeter edges, then welded with an electrofusion welding rod attached to a transition strip covering the seam between the floor sections. When properly performed, the weld creates a seal that is extremely strong and waterproof. Typically, SiteSaver panels will break or split in the non-welded plastic sections before the weld fails. Penda has conducted field testing to ensure the best design to provide a waterproof solution.

The ribs are engineered to maximize the overall strength, flexibility, and stability of the product. The corrugated design also helps convey runoff to specific location on the pad site. Additionally, the corrugations allow the SiteSaver to stack well for shipping purposes.

The engineered corrugations help direct runoff to a specific side of the SiteSaver. From there, runoff can be collected and conveyed to holding basins via ditches and/or pipes.

SiteSaver provides containment, but it is not recommended to drive directly on the panels. We recommend using gravel or rip rap (4″ deep) as a driving or working surface placed on top of SiteSaver. SiteSaver also works well with many types of rig-mats which provide a nice driving and work surface, but do not provide containment. Both gravel/rip rap and many types of rig-mats have been tested and approved to use with SiteSaver, including extremely heavy, steel mats.

There are several reasons for the gravel:

  1. The primary purpose of the gravel or rig-mats is to provide a safe work surface. The gravel (and/or rig-mats reduce) the possibility of slip/trip falls and provides a safer surface for evacuation in case of an emergency. Without these surfaces, wet conditions can make the HDPE material very slippery adding to a possible slip hazard.
  2. The gravel (and/or rig-mats) also protect and prevent damage to the SiteSaver pad. While the HDPE material is very robust certain site activities could cause damage, or in extremely severe cases, even penetration damage to the pad. For example, during fracking the extreme pressures exerted on the pump discharge manifold causes a great deal of vibration and movement of the manifold pipes. The gravel or rig-mats will protect the pad from this activity and many other site activities.
  3. Placing gravel on the pad will provide a drivable work surface. Vehicles can enter, drive across the pad, and exit the pad without compromising the protection provided by the pad.

If there is a spill on the gravel, surface layers can either be broken up by hand tools or by a Skid-Steer loader. If the spill has soaked through the entire depth of gravel, any gravel not able to be collected by hand tools or a Skid-Steer, should be removed with a vacuum truck with enough suction to remove rock from the channels between the ribs.

Gravel contaminated by a spill must be taken to a facility capable of remediating the contaminants on the gravel. Only clean gravel may be used as a replacement material.

If there is a spill on the rig-mats, spread an approved coagulating/absorptive agent in the area of the spill (above and below the rig-mat) to contain the spill. Then clear the contaminated material using hand tools, skid-steer and/or a vacuum truck. All contaminated material must be taken to a facility capable of proper disposal.

Provided that all gravel where spills have occurred is properly removed, the remaining gravel may be collected and reinstalled at a second site (Note; this policy has been approved by Pennsylvania Department of Environmental Protection, but should be confirmed in other states).
