Concrete car parks face a myriad of problems throughout the annual weather cycles. Not only this, but they are constantly exposed to oil spills, carbon dioxide gasses, de-icing salts and excessive amounts of water.
Waterproofing membrane is used to protect the concrete from these aggressive substances, preventing any serious damage and prolonging the lifeline of the carpark’s utility.
Out of every element of a car park, it is the top deck which is the most exposed to corrosive factors such as UV damage, water overflow, freezing and thawing, and chloride exposure. It is crucial that the top layer of any carpark is protected from these issues, especially if the concrete deck is already cracked or damaged.
The intermediate decks are not exposed to any harsh weather however, they still require protection from de-icing salts which are brought in from the cars, abrasion and deterioration of the concrete.
In addition to this, ground bearing slabs are also required when fitting out a car park, in order to control the moisture due to damaged damp-proof technology.
A feature which must not be overlooked is the ramp of a car park. These slanted surfaces wear quickly and require heavy duty protection against mechanical impact and deterioration.
Most waterproofing decking systems allow skid resistance, walkways and enough crack-bridging protection to be able to withstand minor structural movement. This preventative effort is needed in case of any leaking of surface water that could spread to the decks below.
A liquid substance is usually applied to most car parks for a seamless, tough and elastomeric finish to the concrete, acting as a protective layer which can last for many years, making it the preferred option for engineers across the UK.
Benefits of Liquid Waterproofing include:
- Thin, lightweight material
- Non-abrasive & environmentally friendly
- Durable protection
- Resistant to fire, diesel and brake fluid
- Cost effective & long-term
- Increases the life span for both new and existing structures
- Provides an aesthetically pleasing finish
- Elastomeric & resistant to UV damage
- Capable of bridging the cracks and joints caused by thermal expansion or moving vehicles.
If these protective measures are overlooked, the owner of the car park could face major problems with the steel reinforcement and the reliability of the structure after water damage.
As the UK sees a growth in densely populated areas, parking is becoming an increasingly vital part of today’s mobile community. It is important to ensure the maximum protection when building a car park, minimising any potential damage due to weather cycles, abrasion or deterioration.
