The Process Of Car Park Waterproofing

At Car Park Waterproofing Systems, we are proud to offer a range of market leading solutions for waterproofing car parks. We are not tied to any particular product and will always provide impartial recommendations based upon the unique needs of each car park project. To give you a deeper understanding of the process of waterproofing a car park, we will provide step-by-step guides of how to waterproof a car park using the two most effective materials on the market. These materials are; cold applied liquid membranes and mastic asphalt.

Car Park Waterproofing With A Cold Applied Liquid Membrane

A cold applied liquid membrane is a waterproofing solution which requires no heating nad is applied as a liquid at ambient temperatures. Cold applied liquid membranes cure to form a seamless, elastic and durable waterproof barrier. Cold applied liquid is frequently chosen for car park waterproofing. The excellent waterproofing properties of cold applied liquid membranes means it is also widely used for roofs, walkways, balconies and steps. The main benefits of cold applied liquid for car park waterproofing are; they are easy to apply, cost-effective, safe to use, have excellent elasticity and provide a seamless finish. Here is how to apply a cold applied liquid membrane for car park waterproofing.

Step 1: Car Park Surface Preparation

• Cleaning: The first step of applying a cold applied liquid membrane for car park waterproofing is to thoroughly clean the surface of the car park. This means you should remove all dirt and debris from the car park deck. Then remove any existing sealants or coatings from the car park surface. When cleaning is complete the surface should be completely dry and free from any materials which may impair the adhesion of the waterproofing membrane.
• Repairs: Next there should be repairs of any cracks, holes, or damaged areas in the concrete or asphalt substrate. Any surface issues must be dealt with to ensure a smooth substrate which will enable an even application of the cold applied liquid membrane to the car park deck. This is achieved by planing. Planing is the process of removing layers or uneven sections of a surface to create a smoother, more even finish. Planing is often carried out with specialised machinery, such as a planer or milling machine.  The objective of planing is to create a smooth base which will support an even application of the membrane. The final step of surface preparation is to ensure the substrate has a good key base for adhesion to the membrane.

Step 2: Priming The Car Park Surface

• Application of Primer: The car park surface should be primed with a primer which suitable for use with the chosen cold applied liquid product. The primer improves the adhesion of the liquid membrane with the car park surface. Before proceeding with the application of the cold applied liquid membrane the primer should be completely dry.

Step 3: Applying The First Layer Of Liquid Waterproofing To The Car Park Surface

• First Layer Application: The first layer of the cold-applied liquid should be implemented using a brush, roller or spray equipment. The best way to apply the liquid product should be found in the manufacturers specification. It should be ensured the liquid coating is covered consistently across the car park surface. The reason for this to avoid areas which are not sufficiently protected which can cause leaks over time.
• Curing: One the the first layer has been applied, it should be left to cure in line with the the manufacturer’s guidelines. The cure time for the first layer of waterproofing on a car park can fluctuate depending on factors such as the ambient temperature and humidity.

Step 4: Additional Car Park Waterproofing Layers and Detailing

• Additional Layers: With some cold applied liquid waterproofing systems additional layers will be required. These should be added in accordance to the manufacturers guidelines once the first layer has cured. In most cases additional layers will improve the durability and lifespan of the car park waterproofing membrane.
• Detailing: Complex details on a car park deck should be paid special attention to ensure they are correctly waterproofed. Complex detailing includes areas around; drains, upstands and plant machinery. Complex detailing often requires a special detailing product which often has additional fibres for reinforcement and increased durability.

Step 5: Inspection and Repairs Of The Liquid Car Park Waterproofing Membrane

• Quality Inspection: Once the cold applied waterproofing membrane has cured, the entire car park surface should be analysed for imperfections and areas where there is not sufficient coverage of the liquid applied membrane. These areas should be marked so repairs can be easily executed.
• Repairs: The areas marked for repairs should be fixed. This will often include applying another coating of the cold applied liquid to ensure the whole car park surface has an even coverage to a sufficient thickness.

Step 6: Protective Top Coat Application (Optional)

• Top Coat Application: A protective top coat can be applied to the liquid membrane to provide extra durability. This top coat can protect against a number of factors including; UV light, chemicals, and heavy usage. In many cases, a top coat will extend the life of a car park waterproofing system. A typical top coat for a cold applied liquid car park waterproofing system would be an aliphatic polyurethane.

Step 7: Regular Maintenance Of The Car Park Waterproofing Membrane

• Maintenance Checks: Regular maintenance of the car park deck is imperative to maximise the longevity of the waterproofing membrane. It is strongly recommended to schedule regular inspections of the car park waterproofing and quickly address any issues which appear.

Cold-applied liquid membranes are a leading choice for car park waterproofing due to being seamless, easy to apply and durable. However, the quality of cold-applied liquid membranes can vary significantly between brands and it is recommended to understand these differences before making a choice.

Car Park Waterproofing With Mastic Asphalt

Mastic asphalt is an exceptionally durable waterproofing material often referred to as “The King Of Waterproofing”. Mastic asphalt is applied after blocks are heated to a molten state then applied to the substrate. The mastic asphalt cools and hardens to form a waterproof membrane. This mastic asphalt membrane is seamless and joint-free. Mastic asphalt membranes are well-known for their resistance to water ingress and mechanical damage. Mastic asphalt is often used for car park waterproofing. The popularity of mastic asphalt as a waterproofing membrane for car park decks is due to it having excellent load-bearing capacity, durability, and longevity. All of these attributes make mastic asphalt ideal for meeting the demands of high-traffic applications.

Step 1: Car Park Surface Preparation

• Cleaning: Before applying mastic asphalt the car park deck should be thoroughly cleaned. There should be no dirt, debris or any other substances which may hinder adhesion. Once the surface is cleaned it should be left to dry.
• Repairs: The cleaned car park deck should now be addressed for cracks, holes, or any uneven areas. Defective areas should be repaired and any uneven areas should be rectified before moving on to priming.

Step 2: Priming The Car Park Deck

• Application of Primer: Before the application of mastic asphalt, a bitumen-based primer should be applied to the entire car park deck substrate. The use of such a primer enhances the bonding of the mastic asphalt to the substrate. When applying a bitumen-based primer for mastic asphalt it should be ensured complete coverage is achieved. Once applied the primer should be allowed to dry according to the manufacturer's specification.

Step 3: Laying Roofing Underlay On Fibreglass Tissue

• Laying: Upon the primed surface a 10mm roofing underlay on fibreglass tissue should be laid. This serves as a separating membrane. The benefit of this 10mm roofing underlay on fibreglass tissue being laid is it prevents adhesion, serves as a moisture barrier, protects the substrate from high temperatures and enhances the durability of the waterproofing system by allowing for thermal movment.

4. Applying Roofing Grade Mastic Asphalt

• First Layer: One or two coats of roofing grade mastic asphalt should be applied to the car park substrate. Each coat of mastic asphalt should be spread evenly to guarantee an even finish. This mastic asphalt forms the initial waterproofing barrier for the car park.

5. Applying Paving Grade Mastic Asphalt

• Paving Coat: Next a top coat of paving grade mastic asphalt is applied to provide hardness and durability to the demands of a car park. This layer of paving grade mastic asphalt includes 30% grit for extra hardness. While 40% grit can be added to the paving grade mastic asphalt in areas with especially high demands, such as loading bays with pallet trucks, it must be noted it can be challenging to achieve a proper seal with such a high grit level. Regardless of the grit level in the paving grade asphalt, it should be applied smoothly and compactly.

6. Skid Resistance

• Crimp Roller: To provide a skid resistance to the car park deck surface a crimp roller is used. After applying the paving grade asphalt top coat to the car park a crimp roller is passed over the surface. This crimp roller provides skid resistance and prevents slipping in icy conditions. The use of a crimp roller eliminates the need for an additional anti-slip coating.

7. Detailing

• Upstand Margin: The perimiter of the car park deck should be waterproofed with a 100mm wide margin of roofing grade mastic asphalt. This margin should go between between the parking deck and concrete or brickwork upstand. The purpose of this margin is to allow for movement.
• Angle Fillet: A second angle fillet is added to create a watertight seal between the car park deck and upstand after the paving grade asphalt is laid.
• Upstand Application: For upstands mastic asphalt should be apploed to a minimum height of 150mm. This mastic asphalt should be to a thickness of 20mm, using three coats. Car park upstands should be tucked into a 25mm x 25mm chase cut into the concrete or brickwork, then pointed with mortar.

8. Cooling And Setting

• Curing Time: Once the car park waterproofing is complete it should be left for the mastic asphalt to cool and set properly. The setting time of mastic asphalt can vary, but it typically takes a few hours for the surface to be ready for pedestrian traffic. For vehicular use the waiting time is longer. The correct curing of the mastic asphalt is essential to ensure full strength and durability of the waterproofing membrane.

9. Quality Inspection

• Inspection: Once the mastic asphalt has cooled and set, the surface should be inspected for any imperfections or weak spots. The thickness should be consistent across the car park deck and the surface should be completely sealed. If any areas have issues they should be repaired immediately.

10. Applying A Protective Finish (Optional)

• Protective Layer: In some applications a protective finish will be required. This depends upon the expected traffic and environmental conditions the car park must endure. In situations where a protective finish is required it can help extend the lifespan of the mastic asphalt waterproofing.

11. Maintenance

• Regular Checks and Maintenance: Once car park waterproofing is complete, regular checks and maintenance should be scheduled. The car park deck should be inspected for signs of wear or damage. Although mastic asphalt is highly durable, maintenance can significantly expand the car park's lifespan and prevent the need for major repairs.

Mastic asphalt is especially favoured for its robust nature and ability to form a seamless, watertight layer that's ideal for areas exposed to significant weather variations and heavy traffic. Although the cost of mastic asphalt is higher than other waterproofing membranes for car parks, it often works out cheaper when you analyse the price from the perspective of cost per year of service life.
