GOC388370-CT - Waterproof Chiller Room Floor - Construction Phase

The work in this contract includes but is not limited to:

1. Repair and seal the hairline crack in the floor slab.
2. Carry out a laser-level survey to precisely outline the extent and depth of “depressions” in the floor, where water pooling occurs, to locate the extent and depths of the floor defects.
3. Determine the precise extents and thicknesses of floor surfacing build-up required.
4. Prepare and build-up the depressions/defective areas first.
5. Blast-clean the floor surface to remove existing coatings, grease, dirt, and other deleterious substances that could negatively impact adherence of the topping.
6. Layout the build-up areas, and build-up in layers, filling the depressions and sloping to floor drains, using the surfacing in accordance with the product manufacturer’s instructions.
7. Check that the floor grades have been corrected.
8. Prepare the remaining floor areas for surfacing application by blast-cleaning.
9. Apply one layer of the surfacing at a uniform thickness over the entire chiller room floor, where it is accessible (the floor areas under the raised mechanical equipment is not easily accessible for coating application). Repeat with a second application, if required by the surfacing manufacturer to achieve 100% waterproofing.
