Abstract:
To meet the demands of Internet retailing, landlords holding expiring leases on vintage low-rise buildings are exploring the feasibility of raising the roofs of these buildings to clear heights upwards of 45 ft (13.5 m). What comes next is an evaluation of an existing conventional interior concrete slab-on-ground installed in the facility several decades ago and selection of one of the options available to increase structural capacity of this floor. These options, including bonded concrete toppings, bonded epoxy mortar overlay, unbonded concrete overlay, and removal and replacement of an existing slab, are discussed in the article.
