In construction and environmental work, liners aren’t just a base layer — they’re a critical barrier system designed to protect groundwater, waterways, and long-term site performance.
Different projects demand different liner systems. Here’s a breakdown of where and why they matter:
HDPE (High-Density Polyethylene)
- High chemical resistance and durability
- Ideal for frac ponds, industrial water storage, and landfills
- Prevents seepage into groundwater — critical in energy and resource sectors
LLDPE (Linear Low-Density Polyethylene)
- Flexible and conforming — great for irregular surfaces
- Used in storm ponds, lagoons, and areas with settlement concerns
- Easier installation, especially in tight spaces
Geotextile Liners
- Woven/non-woven fabrics used for separation and filtration
- Common beneath aggregate layers, in drainage zones, and as cushion layers
Spray-On Polymers (e.g., Eco Anchor, Eco Haul)
- Used for dust control, soil stabilization, and erosion protection
- Fast to apply, bonds directly to surfaces
- Excellent for haul roads, slopes, and temporary stabilization
GCLs (Geosynthetic Clay Liners)
- Combine bentonite clay and geotextile for natural sealing
- Used in ponds, landfills, and mining operations
- Self-healing properties when hydrated — ideal for layered systems
Radon Barriers
- Gas-blocking membranes under slabs
- Stop radon gas from entering structures — especially critical in residential builds
Radon Gas Venting Layer Over Radon Rock
- Perforated pipe network in a venting layer
- Channels sub-slab gases like radon out through vent stacks
- A standard for passive or active mitigation systems
Lined Stormwater Ponds (Community Ponds)
- Lining community storm ponds is key to protecting groundwater and waterways
- Prevents leachate and surface contaminants from entering sensitive areas
- Supports municipal compliance and long-term sustainability
Erosion Control Materials
- Includes blankets, mats, geotextiles, and tackifiers
- Keeps soil, sediment, and contaminants contained on-site
- Crucial for slope stabilization and stormwater protection during and after construction
Why It Matters:
- Water always finds a way — and if your site isn’t sealed and stabilized properly, it can take contaminants, fines, and liability with it. From frac ponds to suburban developments, the right system matters.
- At CEC, we install liners and erosion materials with precision, environmental foresight, and long-term performance in mind.
