Car park waterproofing has become an essential element of every multi-storey car park refurbishment and new build. As specialists in car park flooring for exposed and interior decks of car parks, here are the most common questions asked by facilities managers and contractors when planning a waterproofing project…
Let’s start with the basics: Car park waterproofing is the application of a waterproof membrane (or waterproof layer) that essentially wraps the building to protect the underlying structure from being damaged by the elements.
Waterproofing the top deck of a car park prevents ingress of water through the structure of the car park to protect the concrete and steel rebar inside. If water leaks in, you’ll run into various problems over the years with steel corrosion, which will compromise the integrity of the car park’s structure causing safety hazards and disrepair.
Yes. In fact, the reason why so many car parks now incorporate waterproofing treatments is to protect the decks from harsh chemicals from cars such as oil, de-icers, exhaust fumes, chlorides and other automotive fluids. It also protects the exposed decks from UV damage from sunlight, and weathering from wet and cold weather conditions.
A significant benefit of waterproofing is how it provides protection from abrasion and wear in high traffic areas. The material also increases safety thanks to its anti-slip properties, making it ideal for pedestrian walkways too. Because it comes in various colours, it can also be used to zone different areas for drivers and pedestrians.
Car park waterproofing actually saves property owners and facilities managers money, as its durability and crack bridging properties means a longer life and less maintenance. The material has been designed to repel oils and chlorides from impregnating the surface, which means easier cleaning too. Consequently, repair and maintenance costs are kept to a minimum.
At Roadgrip, we use waterproofing systems that are cold applied in liquid form. The advanced systems have been designed to cure and dry quickly with minimum downtime.
Yes. Subject to surveys and assessments, the systems we use can be applied to concrete, polymer modified cementitious screeds and asphalt substrates.
As specialists in car park waterproofing, we approach each project individually, however there are generic stages that apply. We begin by preparing the surface with shot blasting or diamond grinding (or both) and then prime and hand-apply the products for a perfect finish.
After this is cured (depending on the system, it could involve multiple layers), we apply the wearing course. This comes with anti-slip properties in multiple UV-stable colours to suit your brand and aesthetics.
At Roadgrip, car park waterproofing can be arranged as a standalone project or as part of a full refurbishment or build. Our team works either as a principal contractor or partner depending on the job.
We often work on waterproofing as part of structure care projects where we also treat the floors and walls of multiple car park decks. Decorating, signage and internal deck resin flooring is frequently included in that.
