In open-pit operations like this, bench design is everything. By displacing the rock face in engineered steps, we ensure maximum safety, stable slopes, and a highly controlled muck pile. Watch how clean this bench drops!💥

Landfills aren’t just hills of trash; they are massive, highly engineered underground bowls called “cells.” To maximize the capacity of a landfill and extend its operational lifespan, operators must dig deep into the ground. When they hit hard bedrock, standard excavators and bulldozers can’t break through it. Blasting is the fastest and most cost-effective way to fracture that solid rock so it can be excavated.💥
