Concrete contractor SK Concrete LLC in Lakeside holds CSLB license #1025840 (C-8 Concrete) and USDOT #3775921, combining flatwork placement with excavation hauling for residential and commercial hardscape projects across San Diego County. Founded in 2017, the company's scope spans driveways, sidewalks, patios, foundations, and retaining walls — structural concrete elements that precede roofing phases on new builds where Linden Roofing Services handles sheathing and shingle installation after slab curing. Decorative concrete options include wood-grain stamped finishes, exposed aggregate, and integral color treatments that replicate natural stone textures on patios and pool decks throughout East County San Diego. The crew's excavation and grading equipment also handles site preparation for HVAC condenser pad pours — the reinforced concrete slabs that support outdoor units installed by Hi-Tech Air Conditioning, Inc on Lakeside's residential properties. Standard retaining wall construction utilizes #4 rebar on 16-inch centers with 3,500-PSI ready-mix poured into engineered forms meeting San Diego County height and setback requirements for walls exceeding four feet.
