What Questions should I Ask Concrete Contractors in Denver?

When hiring concrete contractors in Denver, it is essential to ask specific questions to ensure they can handle the region’s unique geological challenges, such as expansive clay soils and freeze-thaw cycles. Based on local requirements and industry standards, you should ask the following questions:

1. Certifications and Licensing: Ask if the contractor and their products are ICC and ISO certified. Additionally, verify if they hold the valid licenses and supervisor certifications required by Denver’s Community Planning and Development.

1. Experience with Local Conditions: Inquire about their experience managing Denver’s expansive soils and whether they perform geotechnical testing before starting a project. You should also ask if they are familiar with local building codes and permitting processes, including the Waste No More recycling mandate.

1. Materials and Solutions: Ask what specific products they use for foundation stabilization or crack repair, such as helical piers, push piers, or specialized epoxy injections. Inquire if these materials meet ASTM standards and offer freeze-thaw resistance.

1. Warranties and Contracts: Request a detailed breakdown of costs and ask about the specific warranties provided for both the labor and the products used.

1. Professional Affiliations: Ask if they are members of professional organizations like the Colorado Ready Mixed Concrete Association (CRMCA), which indicates an adherence to high-quality industry standards.
