1. ABRASIVE BLASTING / SURFACE PREPARATION
Abrasive blasting is the operation of forcibly propelling a stream of abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface, or remove surface contaminants.There are numerous generic terms for this application usually related to the abrasive media used like steel grit, steel shot, copper slag, garnet, glass beads and aluminium oxide.The equipment and blasting variants / process of Leads includes:
|Portable Blast Equipment||Grit blasting||Shot blasting|
|Blast Cabinet||Soda blasting||Bead Blasting|
|Blast Room||Steel Grit||Steel Shot|
2. PROTECTIVE / INDUSTRIAL COATING
An industrial coating is a paint or coating defined by its protective, rather than its aesthetic properties, although it can provide both. The most common use of protective coatings is for corrosion control of steel structures such as offshore platforms, bridges and underground pipelines.A typical coating system may include a primer, an intermediate coat, and a top coat. The polymer film acts as a physical barrier between the steel substrate and the corrosive environment such as atmosphere, water and soil. The industrial coating services offered by Leads includes:
|Epoxy Coating for Oil & Gas and Marine Industry|
|Cementitious Spray Fireproofing|
|Hydro Carbon Fireproofing|
|Intumescent Coating / Fireproofing|
|Pipeline Girth Weld Coating|
Fireproofing, a passive fire protection measure, refers to the act of making materials or structures more resistant to fire, or material for use in making anything fire-proof, or the act of applying such materials. Applying a certification listed fireproofing system to certain structures allows these to have a fire-resistance rating. An item classed as fireproof is resistant in specified circumstances, and may burn or be rendered inoperable by fire exceeding the intensity or duration that it is designed to withstand.
|Commercial construction||Structural steel to keep below critical temperature ca. 540 °C|
|Residential construction||Electrical circuits to keep critical electrical circuits below 140 °C so they stay operational|
|Industrial construction||Liquified petroleum gas containers to prevent a BLEVE (boiling liquid expanding vapour explosion)|
|Intumescent Fireproofing||Marine (ships)||Vessel skirts and pipe bridges in an oil refinery or chemical plant to keep the structural steel below
critical temperature ca. 540°
|Cementitious Fireproofing||Offshore construction||Concrete linings of traffic tunnels|
|Tunnel concrete walls and ceilings or linings|
|Under and above ground mining operations|
4. PIPELINE COATING
The application and maintenance of anticorrosion protection is one of the most important aspects affecting pipe manufacturing, laying and operation of pipelines. The two essential components of pipeline protection are: Anticorrosion Coatings and Cathodic Protection. Both are vital to ensuring the long life and operating safety of long pipelines.Depending on the plant configuration, the following types of external coatings may be applied:
Fusion–bonded powder coatings (FBE)
Multi–layer extruded polyolefin such as polyethylene (PE) or polypropylene (PP) coatings — the latter has found substantial use in high–temperature and offshore applications. An epoxy anti–corrosion primer is applied to the pipe. It adheres to a normally non–compatible mechanical outer layer of polyethylene or polypropylene by means of an adhesive layer. This system arose in response to the perceived vulnerability of strictly epoxy coated systems.
Multi–component epoxy and polyurethane coatings — epoxy coating is available in either “thin film” or double layer. The epoxy is the anti–corrosion agent.
Hot tape coatings — iInclude the use of heat shrink tape as well as the Vanguard® three–layer tape system and the Synergy® hot tape system. Vanguard, sometimes called “three–layer in a tape”, produces a DIN compliant three layer coating when the tape is fused onto the pipe surface. Factory–applied tape systems allow the pipe coater to avoid expensive purchases of extrusion and other equipment normally associated with three–layer PE or PP coatings.
Hot enamel coatings — coal tar or bitumen/asphalt coatings are applied in molten form with wraps of fiberglass and other felt tapes. While the coating life is excellent, HSE (health, safety and environment) concerns have diminished their use over time.
In addition, internal coating materials may be applied including:
Fusion–bonded powder coatings
Multi–layer epoxy and polyurethane coatings
Coal tar and modified coal tar coatings
5. WATERPROOFING & INSULATION SOLUTIONS
Regardless of the structure type, choosing appropriate waterproofing solutions and techniques requires an evaluation of factors, such as cause/effect relationships, useful life, constructability, environment, aesthetics, and the overall cost-benefits of the alternatives. ABSTRACT understands the wide range of available solutions, and has significant experience in the selection and application of these solutions for our clients.
The commercial and industrial requirement services offered by Abstract includes:
- Vapor Barrier / Damp proofing
- Substructure Waterproofing Works / Basement Waterproofing

In building construction, waterproofing is a fundamental aspect of creating a building envelope, which is a controlled environment. Roofing materials are generally designed to be water-resistant and shed water from a sloping roof, but in some conditions, such as ice damming and on flat roofs, the roofing must be waterproof. Even the roof covering materials, siding, foundations, and all of the various penetrations through these surfaces need to be water-resistant and sometimes waterproof.
Many types of waterproof membrane systems are available, including felt paper or tar paper with asphalt or tar to make a built-up roof, other bituminous waterproofing, EPDM rubber, hypalon, polyvinyl chloride, liquid roofing, and more.Walls are not subjected to standing water, and the water-resistant membranes used as housewraps are designed to be breathable to let moisture escape. Walls also have vapor barriers or air barriers.
Damp proofing is another aspect of waterproofing. Masonry walls are built with a damp-proof course to prevent rising damp, and the concrete in foundations needs to be damp-proofed or waterproofed with a liquid coating, basement waterproofing membrane (even under the concrete slab floor where polyethylene sheeting is commonly used), or an additive to the concrete.A potential problem in earth sheltered dwelling is too much humidity, so waterproofing is critical. Water seepage can lead to mold growth causing significant damage and air quality issues. Properly waterproofing foundation walls is required to prevent deterioration and seepage.
6. TRAFFIC DECK SYSTEM
The Traffic Deck System offers the ultimate protection to concrete floors subject to the long-term stresses produced by the constant wear of vehicular traffic onto a coating system. A combination of systems can be produced using the various products within the range to ensure that final protection and finish offered are tailor-made for the end use of the floor. What’s more, the final PU Topcoat can be produced in a wide range of attractive colours to match the surrounding décor.This full system represents the latest in reinforced glass flake epoxy and polyurethane technology, and completely outdates the use of aggregate/sand as a reinforcement to the coating.

7. GRP LINING
GRP Lining has diverse applications including Corrosion Resistance, Structural Strengthening and Waterproofing. It can be found in most if not all Water Storage Tanks, Sewerage Tanks, Chemical Storage Tanks, Tank Roof Lining, Manholes, Sewerage Sump Pit, Cooling Towers, Chemical Plants, Fire Fighting Networks, Pipeline Networks, Water Transmission Pipelines, etc.
Special grade resins are used to attain various properties, which allow the GRP Lining to withstand resistance to fungi & algae, strong acids, chemicals and high temperature. It’s an effective alternative to component replacement.GRP Lining will completely and seamlessly seal the cracks, leaks, corrosion and flaking materials. It offers a new life to damaged/eroded walls providing a long term, secure environment at a fraction of the cost of a total rebuild.
Method of Normal GRP Lamination – on Concrete / Steel Tank Surface
1. After the surface preparation and removal of dust, first coat of resin is applied on the concrete surface. Care is taken to see that the resin fills all voids in the concrete surface so as to avoid the formation of air bubbles.
2. Prime Coat – Resin is applied on concrete surface. Then first pre-trailed layer of glass fibre (CSM) is placed on the resin applied surface.
3. A woolen roller is used for applying the resin on the mat.
4. Second layer of glass fibre (CSM) is placed over the first layer with resin applied over it.
