SBE Certified Construction Equipment Rentals and Sales

“BUILDING ANSWERS”.  For more than thirty years, we have been distributors of building materials, construction supplies, construction equipment, and outdoor power equipment. When you need building answers, think of Gamka Sales first!

Gamka is one of the largest independent construction suppliers in New Jersey. We cater to concrete, site and landscape contractors. We sell, rent and service most major brands and are a certified warranty center for everything we sell. If a contractor has anything to do with concrete, from placing it to restoring it and every stage in between, Gamka can help. We have the equipment to vibrate it, screed it, finish it, heat it, grind it, drill it, and cut it. We have the ties, the chairs, the expansion joint, the fillers, the anchors, the keyway, the stakes, the insulation. We have the chemicals to seal it, cure it, damp proof it, stain it, clean it, release it, bond it, grout it, level it, accelerate it, retard it and protect it. If you don’t want leaks Gamka has the water stop, if you have leaks we have the plugs. Got cracks? We have the caulk and patches. Concrete contractors come to Gamka for solutions to problems and with a staff sharing 250 years of expertise, contractors leave with answers.
