Chicago Botanic Gardens


CTLGroup provided materials recommendations, design detailing, and construction procedures to improve appearance and avoid cracking of floor systems in the Botanic Garden Plant Science Center visitor gallery. CTLGroup worked with the architect to review and revise concrete mix designs, as well as to develop construction details to avoid unwanted random cracks in the thin overlay radiant heated concrete.

Placement patterns for radiant heating tubes, construction joints, sawcut shrinkage control joints, and insulated subbase details were critically evaluated and finalized. Our team also developed procedures for the placement, finishing, and curing to maximize the uniform appearance of the floor finish over this large area. In laboratory floors, CTLGroup developed repair plans for areas that required corrective action before installation of resilient floor coverings. After installation, the laboratory floors had a uniform appearance and no reflection of the excessive cracks that occurred during construction.
