We are thrilled with the crew, Oso, Jake and Omar that came out to do our job! We have a pretty large ranch home and our back patio slab had sunk about 4-5” and was pulling away from our house. These guys were great! They were respectful, friendly and very knowledgeable what needed to be done. Oso explained everything they would be doing and answered all of our questions! We watched them repair our concrete and they were professionals for sure! When they were finished, they made sure they cleaned off the patio of any debris that was left and used a blower to clean the concrete. We felt very fortunate to have this crew do our repairs! Thank you guys!

Isac and his co-worker did an excellent job raising a potion of my garage floor and three sections of my driveway. They did an great job applying grout in the garage and driveway. My only objection is that the grout used in the driveway is beige and doesn't very well match the concrete.

Manny Bello and Jose Ortiz from Ground Works arrived earlier than expected and assisted us with preparing the garage for the lift project- so much appreciated their help and advice! They both were very polite, friendly, and professional. I totally recommend Ground Works - they do great work and hire competent workers! Thank you Manny and Jose for your work today! JP came initially to assess our needs and he was excellent as well!!
