Geogrids for Road Construction & Stabilization
Rigid Pavement Roads. Tensar geogrids can help you build stronger, longer-lasting rigid pavements. Building a rigid pavement structure with a geogrid layer will reduce deformation better than extremely thick aggregate base sections. This enhanced pavement design creates a more uniform and resilient pavement structure.

Unit Price
The "Unit Price" (or "unit cost") tells us the cost per liter, per kilogram, per pound, etc, of what we want to buy. Just divide the cost by the quantity: Example: 2 liters for $3.80 is $3.80/2 liters = $1.90 per liter. Comparing. Comparing Unit Prices can be a good way of finding which is the "best buy".
