Specializing in rock drilling and controlled blasting in Alpine, Tom C Dyke Drilling & Blasting operates from Tavern Road near the Viejas Casino & Resort corridor with an estimated five to nine crew members. Site clearance for construction pads on Alpine's granite-rich terrain often follows tree removal and vegetation management by firms such as Artistic Arbor Gardens Inc on Hi Ridge Road in Lakeside. The company's drilling and boring capabilities serve residential lot preparation, commercial site development, road construction, and utility trench excavation across East County's rocky substrates. Pool excavation in Alpine's decomposed granite soil frequently requires pre-drilling and fracturing before conventional digging equipment can operate, a preliminary phase that precedes the structural work performed by Gammon Pools Inc on Mapleview Street in Lakeside. Heavy equipment operations include pneumatic rock hammering, controlled explosive charges for boulder removal, and precision boring for foundation pier holes on sites where standard augering cannot penetrate the native rock layer.
