Parkade Waterproofing

A vehicular traffic coating is a wear system, not a permanent one. The base and reinforced layers usually outlive the topcoat by years, so the practical answer is that the wear coat needs recoating well before the whole system is replaced. Ramps, turn zones and entries typically thin out first, and recoating those areas on their own is normal maintenance.

Yes. Parkade work is normally staged in sections so a portion of stalls stays open while another cures. The constraint is cure time, not application time: the deck section has to stay free of vehicles until the topcoat has cured, which depends on temperature and humidity. Cold, damp weather stretches that window, so scheduling matters more than crew speed.

That is efflorescence and reinforcing corrosion. Water passing through the slab carries dissolved lime out with it, leaving white crust, and once it reaches rebar the steel rusts and expands, which spalls the concrete off from the inside. It is a sign the deck above has been leaking for a while. Coating over the top without repairing the slab traps the problem.

No. A penetrating sealer soaks into the concrete and reduces water and salt absorption, but it does not bridge cracks and it is not a membrane. A traffic-bearing waterproofing system is a continuous elastomeric layer applied over the slab, detailed at every drain and joint, with a sacrificial wear surface on top. Sealers are maintenance; membranes stop water getting through.
