Complete Geomembrane Accessory Systems for Secure Installation

A geomembrane liner system is only as strong as its detailing. Proper anchoring, penetration sealing, seaming, and edge termination are critical to long-term containment performance. GeoCHEM provides a full range of geomembrane accessories engineered to support field installation, repair, and securement of LLDPE, HDPE, polypropylene, and specialty liners.

Whether the application involves environmental containment, water storage, tank lining, vapor barriers, or temporary covers, our accessory systems ensure continuity, durability, and wind resistance.

Securement & Ballast Systems

GeoSkrim® Reinforced Sandbags (8 Mil & 12 Mil)

Designed to secure large geomembranes and reinforced covers, GeoSkrim sandbags are manufactured from reinforced extrusion laminate material for superior tear resistance.

Benefits include:

• Heavy-duty scrim reinforcement

• Improved wind resistance compared to standard sandbags

• Reusable design

• Ideal for temporary and permanent liner ballast

Common uses:

• Landfill caps

• Pond liners

• Temporary containment covers

• Agricultural covers

• Construction enclosure films

Proper ballast placement reduces uplift and protects seam integrity during high-wind conditions.

Penetration Sealing & Detailing

GeoBoot System

Pipe and vertical penetrations are among the most common failure points in liner systems. The GeoBoot System is engineered to provide a secure, watertight seal around penetrations that pass through vapor barriers or geomembranes.

Applications include:

• Under-slab vapor barriers

• Tank penetrations

• Pond aeration lines

• Drainage piping

• Utility risers

Proper boot detailing maintains membrane continuity and minimizes leakage risk.

Field Seaming & Repair Materials

GeoCHEM Welding Rod (4mm & 5mm)

Used for extrusion welding of HDPE, LLDPE, and compatible geomembranes, GeoCHEM welding rod supports:

• Field seam repair

• Patch installation

• Pipe boot attachment

• Detail welding work

Packaged in 10 lb spools and manufactured to meet performance requirements for field fusion applications.

Proper welding rod selection ensures chemical compatibility and structural seam integrity.

Mechanical Attachment & Tie-Down Solutions

Geo-Clips

Full-size 11” clips designed to secure poly sheeting to scaffolding and temporary framing systems. Ideal for:

• Construction enclosures

• Dust containment

• Temporary weather barriers

Provides rapid installation and secure fastening without damaging film materials.

Tarp Grabbers & Tie-Down Buttons

Traditional grommets often tear out under load. Tarp Grabbers and Tie-Down Buttons distribute tension across a wider surface area, significantly reducing pull-through failures.

Advantages include:

• Eliminates need for pre-installed grommets

• Stronger hold under wind load

• Repositionable installation

• Suitable for reinforced poly and standard polyethylene films

Ideal for:

• Temporary containment

• Geomembrane edge securement

• Agricultural covers

• Scaffold enclosures

Seam Tapes & Bonding Solutions

High-performance seam tapes and bonding materials provide reliable joining of compatible films and vapor retarders where thermal welding is not required.

Applications include:

• Vapor retarder seam sealing

• Patch repairs

• Temporary liner systems

• Construction film overlaps

Proper seam treatment is critical to maintaining vapor, gas, or liquid containment continuity.

Fabrication & Customization Services

In addition to standard accessories, GeoCHEM offers:

• Factory-fabricated panels

• Custom boot fabrication

• Pre-welded pipe penetrations

• Reinforced edge hems

• Specialty detailing solutions

Custom fabrication reduces field labor, improves quality control, and enhances installation efficiency.

Compatible Liner Systems

Our accessories support installation and detailing of:

• LLDPE Liners

• HDPE Liners

• HDPE Alloy Liners

• HDPE Alloy Tank Liners

• Polypropylene Liners

• Fish-Safe Liners

• Geomembrane Patch & Seam Tape Systems

Selecting compatible accessories ensures chemical resistance, seam performance, and long-term containment reliability.

Installation Best Practices

For optimal performance:

• Match welding rod material to liner resin type

• Properly clean surfaces before welding or taping

• Maintain recommended ballast spacing in windy conditions

• Detail penetrations prior to system commissioning

• Follow manufacturer welding temperature guidelines

Accessory selection and proper detailing significantly reduce failure risk and extend service life.

Applications

• Environmental containment

• Secondary containment systems

• Water reservoirs and ponds

• Tank liners

• Landfill covers

• Construction vapor barriers

• Temporary industrial containment
