SPECIFICATION OF BITUMEN MASTIC
A Technical Overview with Basekim in UAE and Turkey
As the construction industry evolves, so does the need for precision in materials. The specification of bitumen mastic is one such detail that contractors and engineers cannot overlook. In fact, every successful infrastructure project depends on using the correct grade and formulation. That’s why Basekim, trusted across the UAE and Turkey, plays a vital role in supplying and guiding the use of British Standards-compliant mastic asphalt.
What Is Bitumen Mastic and Why Specification Is Critical?
Bituminous coating is a robust, waterproof material composed of asphaltic cement, fine filler, and mineral aggregate. Consequently, it creates surfaces that resist weather, moisture, and mechanical stress. However, not all mastic mixtures are created equal. Therefore, project engineers must rely on clear asphalt mastic specification to select the proper product.
in other words, if you skip this step, the wrong type of asphalt could lead to early failures and costly repairs. As a result, every tender must include specific references to the bitumen mastic standards that apply.
Why Basekim Stands Out in UAE and Turkey
First of all, Basekim does more than manufacture coatings. In addition, they provide tailored technical advice to architects, civil engineers, and procurement teams. Because of this, they are the top choice in the UAE and Turkey for accurate bituminous mastic grading and supply.
Moreover, their production lines follow rigorous controls that match every requirement listed in the British Standards. Thus, working with Basekim means guaranteed quality and compliance.
Bitumen Mastic Specification by Application
To ensure proper usage, each application area must refer to its designated BSS table and column. The following table outlines the most common use cases:
| Use Case | BSS Reference | Table/Column | Recommended Cement Type |
|---|---|---|---|
| Roofing | BSS 6925 – 988 | Table 3, Col. 2 | Medium hardness asphaltic cement |
| Tanking & Damp-proofing | BSS 6925 – 1097 | Table 3, Col. 2 | Waterproof-grade asphaltic cement |
| Industrial Flooring | BSS 1076 – Grade A & B | Tables 5 & 6 | Heavy-duty flooring mastic |
| Road Paving | BSS 1447 | Table 1, Col. 3 | High-resistance paving mastic |
As shown, the specification of bitumen mastic directly determines the cement type, which in turn ensures long-term performance.
Choosing the Right Aggregate: Limestone or Natural Rock?
In most cases, limestone and natural rock aggregates are the go-to choices. While limestone offers a smoother, cleaner finish, on the other hand, natural rock provides superior pressure resistance.
Because each type has different physical properties, Basekim assists contractors in choosing the aggregate that aligns best with the specified bitumen mastic standards.
Don’t Forget the Isolating Membrane
Equally important, any application of bitumen mastic must include the right isolating membrane. Depending on the environment and structure, options may include:
-
Kraft building paper
-
Fiberglass tissue
-
Sheathing felt
Consequently, Basekim’s team evaluates these choices based on each project’s location, moisture level, and expected load.
Add Surface Treatment for Enhanced Performance
After applying the mastic layer, a reflective or protective surface treatment increases durability. Common materials include:
-
Bituminous aluminum paint
-
Acrylic colored paint
-
Mineral chippings
As a result, surface treatment not only enhances appearance but also improves safety by reducing slips and UV degradation. Therefore, Basekim always recommends adding this layer as part of the total mastic asphalt specification.
Writing Clear Tender Documents: Step-by-Step
To avoid confusion and legal disputes, contractors must write tenders with clarity. Thus, here’s a checklist to include in your tender:
-
Exact BSS number and cement type
-
Table and column reference
-
Aggregate type and grade
-
Chosen isolating membrane
-
Surface treatment plan
With these elements, your tender becomes transparent and ready for execution. Moreover, Basekim offers assistance in drafting these documents for their clients in the UAE and Turkey.
Common Industries That Depend on Bitumen Mastic
The specification of bitumen mastic influences a range of applications:
-
Roofing Systems: High UV and water resistance
-
Tanking & Waterproofing: Subsurface moisture protection
-
Industrial Flooring: Heavy load and chemical resilience
-
Highways & Urban Roads: Shock absorption and surface protection in every scenario, Basekim ensures correct grading and batch control for the application at hand.
The Dangers of Incorrect Specification
Unfortunately, many coating failures occur due to incorrect specifications. For example, using roofing-grade cement on a road surface would cause premature cracking.
Therefore, it is critical to follow official bitumen mastic standards closely. Basekim not only supplies the materials but also double-checks compliance before product delivery.
Environmental and Safety Advantages
Unlike traditional tar-based coatings, modern bitumen mastic is much safer. Furthermore, it has low toxicity, emits minimal fumes, and meets EU environmental standards.
Because of these features, Basekim’s materials are favored in green building projects across the UAE and Turkey.
