About Us

After several years working in concrete and gaining hands-on experience in the building and construction trades, Greg Robles founded GR Concrete Construction LLP in 1990. What began as a residential concrete operation has grown into a contractor capable of delivering large-scale commercial and municipal concrete projects. Today, GR Concrete Construction continues to operate with the same principles it was built on by taking pride in every project, executing work with precision, and consistently delivering high-quality concrete construction.

“On behalf of Brinkmann Constructors and the Wind Crest team, we wanted to extend our appreciation for a job well done on the Wind Crest RB2.2 project in Highlands Ranch, CO. Your assistance lead to a successful turnover of this project with a highly regarded client. Brinkmann Constructors appreciates your firm’s hard work, customer service, quality, and integrity shown on this project. We look forward to working with your organization on future projects.”

“We had the privilege of working with GR Construction, LLP on our projects over the last few years. GR is a “Turn-Key Concrete” contractor that specializes in site concrete, cast-in-place structural foundations, and building flatwork for both slab-on-grade and elevated slabs. Their experience and expertise in their foundation work is excellent and true to line and grade. Their layout work is spot-on and they can often find errors in construction documents and address issues prior to concrete placement, thus eliminating extra cost to replace misplaced concrete, anchor bolts, and embeds. GR Construction, LLP can be relied upon to meet or exceed schedules when given the opportunity to do so. Their knowledge and performance of structural concrete work is some of the best we have had on our projects and we continue to solicit them for our work. Please feel free to contact me should you have any questions and/or concerns regarding GR Construction’s abilities to perform as a structural concrete subcontractor.”

“Brikmann Constructors has been working with GR Construction, LLP on multiple projects over the last several years. GR Construction, LLP typically performs a “Turn-key Concrete” subcontract that includes site concrete, cast-in-place structural foundations and building flatwork (both slab on grade and elevated decks). In recent years, they performed a turnkey concrete subcontract on the WindCrest Extended Care Center building which included a complex foundation layout including 5 building wings with interior foundations and stemwalls for load bearing structural steel walls. The subcontract also included slab on grade, (3) elevated decks, and site concrete package. Their experience and expertise in their foundation work was apparent in the quality of their work, knowledge of their site foreman, and involvement of upper management including the owner of the company. Their layout and anchor bolt placement was accurate and their onsite field staff was able to identify discrepancies in the construction documents to avoid errors and re-work. GR Construction, LLP met the schedule expectations on this project and have exemplified customer service meeting the needs of us as a general contractor. Their knowledge and performance has been noted as we continue to solicit them to perform on our projects. Please feel free to contact me should you have any questions and/or concerns regarding GR Construction, LLp’s abilities to perform as a structural concrete subcontractor.”
