Concrete
Carbon Graphite Solutions

		Problem: Mid-state Michigan hospital required a change of use of a floor supporting structure from Patient Care to an MRI machine. Existing 1930's pan joist construction could not handle new imposed loads from the imaging head. Solution: Building Restoration, Inc. workers install horizontal carbon fiber strips within the floor slab area, directly over the floor joists. Each strip has a tensile design strength of 406,000 PSI. Installation required removal of two inches of the existing concrete overlay.
Close-up of the installation of vertical stirrup reinforcements. A total of 44 stirrups were installed in the area of the MRI machine on both beams and floor joists.
		Installation complete-- Magnetic Resonance Imaging Head installed on top of finished tile floor. This is the same location as the first picture above

Crack Movement Arresting

Problem: Existing concrete floor has construction joint passing through area to be tiled. Movement within the existing construction joint due to thermal changes will cause the tile system to crack.

Solution: Installation of carbon fiber reinforced stitching strips at 8" centers along crack length. Additionally, note carbon fiber wrapped around base of log post to reduce cracking movement (also see fiber wood applications).

Constraints: Epoxy application needs to have grit texture for proper bond with floor tile grouting and unevenness at control joint slabs requires flexible carbon graphite strips to follow contour.

Location: Residential, Allegan County, MI
Engineer/Architect: None

Problem: Block wall within the residential structure is bowing inward due to lack of proper reinforcement placement in the original construction. Wall has been displaced by 2 inches.

Solution: Application of pultruded carbon fiber strips.

Constraints: None

Location: Residential, Mount Pleasant, MI
Engineer/Architect: MAK Engineering, Inc.

Problem: A mechanical contractor pierced structural reinforcement while coring.

Solution: Application of carbon fiber strips on tensile strength of wall

Constraints: None

Location: Western Michigan University, Dalton Center
