Protecting car parks with advanced waterproofing solutions


Car parks are essential infrastructure in urban areas, serving as the gateway for vehicles to residential, commercial, and industrial spaces. Despite their practical function, car parking garages face constant exposure to the elements, vehicle traffic, and chemical pollutants, all of which can lead to significant wear and tear. Advanced waterproofing solutions are crucial to ensure longevity and functionality. At Robex, we offer multiple advanced waterproofing solutions. Our signature product for car parking garages and car park decks is RX Protadeck, a cutting-edge waterproofing system designed to meet the heavy-duty requirements of car parks.

Why do car parks and decks need waterproofing?

Car parks endure a range of harsh conditions, including exposure to water, oil spills, and the constant pressure of vehicular traffic. Without adequate waterproofing, water can seep into the concrete, leading to cracks, spalling, and corrosion of the reinforcement steel. Over time, this deterioration can compromise the structural integrity of the car park, leading to costly repairs and potential safety hazards.

Effective waterproofing prevents water ingress and protects against chemical attacks, ensuring the durability and safety of car park structures. This is where RX Protadeck excels, offering a comprehensive solution to protect and prolong the life of car parks.

What is RX-Protadeck?

RX Protadeck is a high-performance waterproofing system. It provides a seamless, fully bonded, and trafficable membrane that is both water and chemical-resistant, with added abrasion resistance to withstand the rigours of heavy traffic. 

RX Protadeck offers several key benefits, including excellent durability with resistance to ageing, UV rays, abrasion, weathering, de-icing salts, and chemical attacks. Its versatility allows application to both horizontal and vertical substrates, forming a tough, abrasion-resistant membrane. It is easy to maintain, as it can be cleaned with steam or degreasers, ensuring a pristine surface. Its long service life reduces the need for frequent repairs, making it a cost-effective and reliable waterproofing solution.

One of the standout features of RX Protadeck is its rapid application and curing time. Areas treated with RX Protadeck can be returned to service in under 20 minutes, minimising downtime and disruption. This fast-track waterproofing system ensures a high-performance solution that protects structures from deterioration by water and chloride ions.

Material Specification

  • Primer: Penetrates and seals the substrate, creating a strong bond between the deck and the RX Protadeck membrane.
  • Glass fibre membrane: Facilitates movement and deflection, ensuring flexibility in the structure.
  • RX Protadeck membrane: A 1.8mm high-performance resin membrane that ensures 100% effective waterproofing.
