Black DirtWork Construction

DIRT WORK & PAD BUILDING

Dirt work out of Artesia, NM — building pads and prepping the ground with their own equipment, so each grizzly sits on a site that's built to hold it.

Owner: Mauricio Gabaldon 903-571-8961 blackllc23@gmail.com

American made. No excuses.

Every grizzly is fabricated and welded right here in the USA — and we proudly stand behind our veterans.
