INFRASTRUCTURE DEVELOPMENT
Construction of Infrastructure has become core business for Bitumen World. This speaks to the construction of new or rehabilitation of roads (both national and secondary routes), the development of urban infrastructure, bulk earthworks, the construction of concrete structures and buildings.

Road Construction / Rehabilitation
All works (including earthworks, layer works, surfacing, storm water drainage, concrete structures, road signs, road marking and other ancillary items), done to contract specification; typically, Ministry of Transport or SATCC.

Urban Infrastructural Development
This pertains to the development of commercial or residential erven and associated roads and stormwater drainage, along with provision of various services such as sewer and water reticulation, all as specified. A few successful contracts have been undertaken.
Bulk Earth Works
Earthworks associated with the construction of road and dam embankments and open cast mining activities.
Structural Concrete and Building
There is capacity to undertake both the construction of both reinforced concrete structures and commercial or domestic buildings. The experience thus far i.r.o. structural concrete works stems from the construction of bridges (inclusive of road over rail), various stormwater structures and water retaining structures.
SURFACING OF PAVEMENTS
With the company having started out as a surfacing specialist this ability and capacity remains essential. This capacity supports both surfacing centric contracts (large and small) and the construction or rehabilitation of roads type projects.
Asphalt Paving
Three teams serve the local market, both on own projects, asphalt overlay centric contracts or as subcontractor. To ensure a quality end product and secure supply, the asphalt manufacture and quality control by a laboratory are both done in-house. The capability extends to new road construction, overlays to existing pavements and specialised applications such as substrate to an astro turf hockey pitch.
Bituminous Surface Treatments
These surface treatments include: prime cost, tack coat, single and double seals, cape seal, slurry seal and fog spray; all of which are within the company's experience. Quality end product is supported by the regular calibration of distributors and the monitoring of material quality (bitumen and aggregate).
Surface Defects Repairs
The repairs relate to filling of surface depressions (ruts), crack sealing, patching of potholes and the reinstatement of edge break. The work is carried out to contract specification or else defaulting to SATCC requirements.
Bitumen Handling
Having the facilities to store, heat and transport bitumen gives capacity to undertake remote works. In addition to the handling of bulk supply with tankers, there is also the capacity to decant bitumen from drums and pump in to bulk storage tanks.
MANUFACTURED PRODUCTS
With the company having started out as a surfacing specialist this ability and capacity remains essential. This capacity supports both surfacing centric contracts (large and small) and the construction or rehabilitation of roads type projects.
Hot and Cold Mix Asphalt
Most production of Hot-mix Asphalt relates to medium or fine grade mixes for use on own projects. Specific mix designs may be made available subject to inquiry. Cold-mix is popular for pothole patching and is packed in 50kg bags.
Contract Crushing
Manufacture of specified graded aggregate for both clients or own projects, subject to terms of agreement.
Pre-cast Concrete Units
An in-house facility was previously developed to manufacture pre-cast concrete units. This is chiefly used to supply own contracts with typically culvert portals, various types of kerbs and paving blocks.
