The composition of mastic asphalt allows it to endure the rigors of heavy vehicular movement without succumbing to wear and tear. Its toughness makes it particularly suited for application in high-traffic areas such as car parks and roadways, where durability under constant use is essential. The material's resilience to compression and abrasion contributes to its longevity, even under the weight of heavy vehicles.
Given its durability and low maintenance requirements, mastic asphalt represents a financially prudent choice for waterproofing. The initial investment is offset by the material's extended service life and the reduced need for repairs or replacements, making it a cost-effective option over the long term. This economic efficiency is bolstered by the material's ease of installation and minimal upkeep.
Mastic asphalt's resistance to a wide range of chemicals, including oils, petrol, and other potentially corrosive substances, makes it ideal for use in environments where chemical spills are possible. This resistance ensures that the surface integrity of the car park is maintained, preventing the degradation that can result from chemical exposure and ensuring a longer lifespan for the waterproofing layer.
Mastic asphalt's production process has achieved a carbon zero rating, reflecting its minimal impact on the environment. This sustainable aspect is a significant benefit, aligning with modern construction efforts to reduce carbon footprints and contribute to environmental preservation. The use of mastic asphalt in projects supports sustainable construction practices without compromising on performance or durability.
One of the unique properties of mastic asphalt is its flexibility, particularly at lower temperatures where other materials might crack or become brittle. This flexibility allows it to accommodate minor structural movements and thermal expansion and contraction without compromising its integrity. This adaptability minimizes the risk of cracking and ensures the longevity of the waterproofing protection.
The nature of mastic asphalt makes it exceptionally easy to maintain and repair. In the event of damage, repairs can be conducted quickly and effectively without the need for extensive work. This ease of maintenance ensures that the waterproofing layer can be kept in optimal condition with minimal disruption, further extending the life of the application.
To enhance its durability, especially in areas subjected to intense vehicular pressure, up to 30% grit can be added to the mastic asphalt mix. This modification increases the mixture's hardness and abrasion resistance, making it even more suited to withstand the demands of high-traffic parking areas without compromising its waterproofing efficiency.
Mastic asphalt's reliability and effectiveness in waterproofing applications have been demonstrated through its long history of use.

Waterproofing a car park with mastic asphalt is a process that requires careful preparation, application, and finishing to ensure a durable and effective barrier against water ingress. The procedure typically involves several key steps to achieve optimal results:
Using mastic asphalt for waterproofing provides a robust, long-lasting solution that not only protects the structure from water damage but also offers a smooth, durable surface for vehicular and pedestrian traffic. Proper installation by experienced professionals is essential to ensure the longevity and effectiveness of the waterproofing system, making mastic asphalt a reliable choice for car park waterproofing projects.
Vehicle access ramps are subject to considerable down slope forces due to vehicle traction and braking. This makes it imperative to bond the mastic asphalt directly to the surface of the ramp.
The surface of the ramp should be tamped concrete with no joints. The tamp marks on the concrete should be across the slope of the ramp. These tamp marks provide a key for the asphalt to bind with.
The concrete needs to be as dry as possible. The reason for this is to prevent any blistering occurring in the asphalt. Once this is achieved a limited amount of high bond primer should be applied. With a vehicle access ramp in a car park no sheathing felt is used. A primary coat of roofing asphalt is applied upon the tamped concrete. This coat should be 15mm in thickness. Next a coat of 25-30mm of paving grade asphalt is applied (if the access ramp needs to endure heavier vehicles such as lorries 40mm paving grade asphalt will be necessary).
The ease of car park repair when asphalt is used is one of the key reasons for it being the best choice of material for a car park which seeks to be cost effective whilst meetings the latest environmental standards. Asphalt being an easy material to repair gives you a vastly extended life span for your car park. This means the cost per year of service for your car park is significantly reduced. To maximise the life span of your car park it is important to take care of any problems when they first occur.
One of the best ways to make sure you stay on top of your car park repair needs is to schedule an annual maintenance survey. This survey is designed to identify small problems before they become larger ones. On a typical survey defects such as failing upstands, expansion joints and pothole repairs are likely to be found. Once completed you will have a good idea of your car park surface conditions and know what is the best course of action to take to get the maximum service from car park waterproofing.
It is not always easy to spot a problem developing in its early stages. For this reason, using an waterproofing expert to conduct an annual maintenance survey on your car park is recommended. The benefit of choosing an expert is they can identify problems and provide solutions before they develop into something more serious. Most of the time a serious problem is only noticed when there are extreme weather conditions, normally this leads to costly damage. You gain two major benefits from investing in a maintenance survey. Firstly, this can potentially save you vast sums of money. And secondly, it can add years to the lifespan of your asphalt car park which will vastly reduce your cost per year of service.
During an annual maintenance survey the most common type of defects identified include:
To conduct repairs to the mastic asphalt deck the process is as follows:
This process illustrates the cost-effective nature of car park repairs in mastic asphalt. Notice how just the affected area needs to be repaired without the need to take up and relay areas which are still performing well. Also, it causes minimal disruption to the rest of the car park allowing business to resume as usual for unaffected areas.
In nearly every instance repair is a better choice than a full replacement of the waterproofing. Hence, the consistently high demand for car park repair work.
