Parkade Membrane Install & Repairs

Vehicles regularly entering parking garages leave water, oil and dirt behind. Heavy salts and gravel tracked in during the winter months can corrode the structure’s concrete and steel support system.

No matter how and where they are constructed, parking garages are vulnerable to these environmental conditions. Over time, concrete becomes susceptible to deterioration as moisture and salts seep in. If left untreated, the structure can become substantially compromised, exposing owners to costly risks.

Rooster Building Group will help identify specific problem areas, hazards and possible proactive maintenance opportunities within your parking structure. Based on our findings, we will recommend a repair and maintenance schedule aimed to avoid costly restoration, decrease liabilities, adhere to bi-laws and maintain the property’s value and useful life as it ages.

Our parkade repair & membrane replacement services include:

  • Complete membrane replacement
  • Membrane repair and patchwork
  • Concrete replacement and structural repair
  • Epoxy injection
  • Non-slip ramp coatings
  • Crack repair
  • Cathodic protection
  • Expansion joint installation/replacement


All types of parking structures are subject to deterioration; therefore Rooster Building Group has identified key indicators to help building owners assess if a parkade is in need of preventative maintenance:

  • Water Leakage: Leaking water can be indicated by exposed metals rusting or by rust stains being evident along parkade walls. These warning signs indicate that the parkade is in need of immediate repairs. The longer the condition is left unattended, the more expensive the consequences can become for property owners.
  • Ponding and Pooling Water–Water and parking garages do not mix well, so standing water is an obvious issue. A simple drain installation or protective waterproof membrane can prevent future, larger problems.
  • Expansion Joint Failure– Failed or failing expansion joints provide another method for water to penetrate and reach the reinforcing steel and connector plates. Typically, repairing expansion joints is much simpler and cost effective, as a preventative maintenance technique, than resolving issues created by corroded reinforcing steel and connector plates. Detecting expansion joint problems and investing in repairs will be beneficial in the long run.
  • Delaminated, Spalled, Horizontally Cracked and Vertically Cracked Concrete– Concrete is prone to crack at some locations. Delaminated or spalled concrete is when a piece of concrete detaches from the structure. Along with delaminating and spalling, vertical and horizontal cracks in the concrete also represent threatening areas of weakness. These issues are problematic as they can lead to structural damage because they allow water to reach the parkade’s reinforcing steel. This type of damage is commonly seen on Post-Tensioned and Conventional Cast-In-Place concrete parking garages.
  • Exposed Rebar (Reinforcing Steel)– If rebar can be seen, there is a problem that deserves swift attention. When rebar is introduced to water, it corrodes and expands up to eight times its original size. This condition usually is the result of a crack in the concrete that allows water to travel through and reach the rebar. The force of the expanding rebar causes more damage to ­the concrete around it, which creates greater access for water and more corrosion. It is imperative to stop this compounding cycle as soon as possible.
