Let’s Talk Containment — Not All Are Created Equal

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.
