Fill & Base
Clay Embankment Fill
Also known as: Clay Fill, Embankment Fill, Impervious Fill, Pond Clay
Clay Embankment Fill is a cohesive, fine-grained clay material used where you need fill that holds back water instead of letting it through. It packs down tight and forms a low-permeability mass, which makes it the material of choice for building embankments, berms, and pond cores. When the job calls for a water barrier and not a drainage layer, this is the fill you want.
Applications
- Embankments & Berms
- Pond Cores & Liners
- Water Barrier & Cutoff
- Fill & Grading
- Erosion Control
Why It Works
Cohesive fill that holds back water.
Clay is fine-grained and cohesive, so when it’s compacted in proper lifts the particles bind into a dense, low-permeability mass. Water doesn’t move through it the way it moves through stone or sand. That’s the whole point of the material: it forms a barrier.
This is why it’s used for the core of an embankment, the liner of a pond, and any berm or dike meant to keep water on one side. Stone and granular fill give you structure and drainage. Clay gives you a seal. To perform, it needs to be placed and compacted near its optimum moisture content, which is how it reaches the density that keeps it tight.
