Can only damaged portions of a membrane be repaired?

Localized repairs may be appropriate for isolated deficiencies where the surrounding membrane remains serviceable. Where deterioration is widespread or the system has reached an advanced stage of aging, broader replacement may provide a more appropriate long-term strategy.

Why are joints important in parking garage rehabilitation?

Expansion, construction and other movement joints help accommodate movement while controlling water penetration. Failed joints can allow water and salts to reach structural concrete and lower levels, contributing to deterioration.

Can drains be included in rehabilitation plans?

Yes. Drains, drainage pathways and surrounding interfaces may be incorporated where deficiencies contribute to standing water or water infiltration. Waterproofing performance depends on both preventing penetration and directing water toward effective drainage.

Why is standing water a concern?

Standing water increases the duration of moisture exposure and can carry chlorides into vulnerable areas. Ponding may also indicate inadequate slopes, blocked drainage or localized surface conditions that should be considered during rehabilitation.

Can ramps be included in parking garage rehabilitation?

Yes. Ramps are exposed to vehicle traffic, abrasion, water, salts and temperature changes and may require concrete repairs, waterproofing, joint work or other rehabilitation measures.

Are beams and columns included in parking garage rehabilitation?

Yes, where deterioration is identified. Plans can include repairs to beams, columns, walls and other structural components, with repair details adapted to their function and observed condition.

Can crack repairs be included?

Yes. However, the repair method should be selected according to the crack's location, width, activity, cause and structural significance. Not every concrete crack should automatically receive the same treatment.

Why are estimated repair quantities used?

The complete extent of concrete deterioration is rarely visible before demolition. Estimated quantities provide contractors with a basis for tendering while recognizing that actual repair quantities may change once construction exposes concealed conditions.

What are unit prices in a parking garage rehabilitation contract?

Unit prices establish agreed pricing for defined categories of work, such as a specified quantity or area of concrete repair. They provide a structured method for adjusting project costs when actual quantities differ from preliminary estimates.

Why are unit prices particularly important for concrete repairs?

Once demolition begins, additional deterioration may become visible. Unit pricing allows actual quantities to be measured and valued according to predetermined categories rather than requiring entirely new pricing for every variation.
