concrete, driveway Grading and forming 28 March 2017 Steve Leave a comment Alejandro and Juan from Gilsa Construction arrived to regrade the roadbed, prepping it for concrete — and to build the lumber forms. Alejandro works the scoop on the Bobcat down the long run of driveway to the street. The chunks of asphalt rubble get loaded into the dump truck. The truck took two loads away. Juan, front, and Alejandro, back, sledgehammer the forms and braces into the roadbed. There will be a rock channel down the center of the driveway to collect water and carry it from the back of the driveway all the way to the street, with the ability for water to percolate into the ground to feed the oaks — and to reduce impervious cover.
