What is Mastic Asphalt?

Mastic asphalt is the most durable waterproofing solution available. It is the traditional choice of specifiers because it has a proven track record of success in a variety of different applications.

It is made up of graded aggregates bonded together in bitumen. When this combination of materials becomes solid it forms a dense impermeable mass.

Why Choose Mastic Asphalt?

1. Durability

Asphalt is one of the most durable waterproof membranes’ available. It has a life span of more than 50 years.

This has led to it being used in many high-profile projects across the UK. Especially in projects which must stand up to sustained use such as bridges and car parks.

In the event of any damage, asphalt also can be easily repaired.

2. Recyclable

According to experts the material is deemed to have hardly any environmental impact. At the end of its useful life, mastic asphalt is 100% recyclable. This makes it an environmentally friendly option.

3. Carbon Zero Status

The Mastic Asphalt was the first industry in the world to achieve the Carbon Zero status. This means any project using an advanced mastic asphalt system will benefit form a 100% CO2 neutral solution.

4. Fully Trained Operatives

All mastic asphalt operatives are taught by professional tutors and undergo a traditional time served apprenticeship.

5. Perfect for Roof Gardens

Mastic asphalt is widely considered to be the most reliable waterproofing system available for green roofing projects and unlike other types of membrane, the material has a long and proven track record in this market place. It has been successfully used on green roof projects for over 80 years.

Its seamless application ensures that plant roots are unable to penetrate vulnerable areas such as joints and seams used in the application of other types of membrane. Matched by its inherent strength and durability together with its built-in green qualities, mastic asphalt can be the only choice for green roof projects – particularly in design situations that may attract foot or vehicular traffic.

6. Fire Resistant

The high mineral content of mastic asphalt renders it virtually incombustible. Mastic asphalt fulfils all the external fire resistance required for a roof covering and achieves the highest rating (p60) – now (aa) – when tested in accordance with BS.1476 part 3:1975. It has also been tested in accordance with draft European standards prEN1187-1 and prEN1187-2. No significant spread of flame was observed and no flame penetration occurred. Mastic asphalt systems also have LPCP accreditation for fire safety.

7. Flame Free Application

Because Mastic Asphalt is laid in molten form it is frequently confused with other types of membrane that require naked flame or torch on application.

For major projects the material is usually taken to site by hot charge tankers direct from the manufacturer and taken to the point where it is needed for rapid installation – a major advantage for contracts with critical time constraints. For smaller projects solid blocks are preheated in boilers placed at ground level.

At no time is there any type of naked flame at the point of installation and because mastic asphalt is so highly flame resistant, there is little or no potential of fire risk.

8. Best Value Roofing Solution

According to independent studies (60-year life-cycle costings) mastic asphalt roofing has proven to be the most cost-effective waterproofing material (savings of approximately 10-15 per cent on alternative systems).

9. Scope of Use

Mastic asphalt has been successfully used to provide unbeatable protection from water penetration for centuries. In recent years, the material has been reformulated to include advanced polymers for increased durability, combining its traditional strengths with modern technology. Not simply a roofing
material, it is used in various applications, including walkways and roads.

It is highly resistant to all types of weather situation and attacks from thermal shock (rapid temperature changes), which are a frequent source of break down in many other types of membrane. Its durability and seamless application means that it is one of the few membranes able to handle consistent heavy foot and vehicular traffic, including from Heavy Goods Vehicles, and still maintain its waterproof integrity. It is also easy to repair should alterations or damage occur.

10. Attractive Finish

Mastic asphalt roofing provides the base for numerous attractive roof finishes:

For example: roof gardens, inverted roofs with stone, slab or timber decking finishes and, of course, roof tiles and reflective coatings.

The material’s unique flooring qualities lends itself to both domestic and commercial specifications for damp proofing and wearing or underlay materials. The option of coloured mastic asphalt flooring and the newly designed polished stone finish (terrazzo) make it the designer’s and architect’s dream – solving two issues in one (damp proofing and floor finish).

The job was booked in straightaway and a team set about taking off old asphalt rebuilding and repairing the big Victorian staircase and then asphalting. The finish was quite amazing, these guys are very skillful at what they do and My husband and I were delighted. They were a professional team really hard working and highly recommend them.” Customer in London

“Ryan and team arrived, late afternoon, as agreed, to review balcony, approx. 25m2, 3 sides fed by tiled roof and one long length hand-rail. Problem, 3 leaks in different places from 10yr old asphalt roof. We discussed the problem and Ryun suggested a choice of two plan of action. We found his quotation very acceptable. This work was completed as agreed, in only a few days, to our complete satisfaction. Eight months after completion, I can now report that after a very wet winter, the roof is in a sound state. An excellent job done.” Customer in Cambridge
