Membrane Roof

Bituminous products are perfect for the waterproofing of roofs on buildings as they move with the structure as they are not too rigid and do not absorb water. Waterproofing membrane systems are designed to protect both residential and commercial buildings through a mixed substance made up of organic liquids that are highly sticky and viscous. They can also be used as a continuous waterproofing membrane for foundations, basements, tunnels, concrete etc. and it is applied by flame bonding.

Application procedure

10cm overtopping shall be allowed for side joints and 15cm overtopping for ends by using welding torch. Joints should be heated and bituminous surface by using trowels before welding the joint together. The transverse joints of the first layer covering should be laid down in an offset position for the top layer. Longitudinal and transverse joints of the first layer should be centered. Roof covers should be laid perpendicular to the slope from the point where the slope is lowest.

• Dimensional stability
• Excellent stability at high & low temperatures
• Higher tear & impact resistance
• Available in plain or mineral finish for light foot traffic

Metal Roofing

Metal roofing is widely used in industrial sheds and warehouses due to its durability and structural efficiency. However, with time, issues such as rusted fasteners, widened bolt holes, and deteriorating sealants lead to frequent water leakage—particularly at joints and overlaps. HAMI INSULATIONS offers two advanced waterproofing systems tailored for metal roofs.

1. Liquid-applied membrane system

High-quality elastomeric coatings such as acrylic, polyurethane, or silicone are applied over a properly prepared metal roof surface. This creates a seamless, flexible membrane that fully bonds to the roof, sealing fasteners, overlaps, and penetrations. Reflective coatings with high solar reflectance can reduce internal heat buildup and improve energy efficiency.

2. Spray-applied polyurethane foam system

The foam expands upon application, sealing all joints, holes, and gaps to form a seamless, fully bonded layer across the metal surface. It is then coated with an acrylic UV-resistant topcoat. This system is certified by the Dubai Central Laboratory and backed by a 10-year manufacturer's guarantee.

GRP Lining

GRP (Glass Reinforced Plastic) is widely used throughout industry, being cost effective, highly durable and due to its flexible process, has a variety of different uses. GRP is an excellent lining system compared to coatings such as epoxies and urethanes, due to the way the system is applied and thickness to which it is applied. It is applied in sheets rather like wallpapering and the advantage GRP has over coatings is that it will cover cracks and even large holes. It is possible to cover defects and uneven substrates with a minimum of 3mm thickness, giving a very strong but still flexible coating.

Application method GRP

• Surface prepared by grit blasting to the standard required for the application
• Prepared areas primed with a coat of resin
• CSM (Chopped Strand Mat) applied to all primed areas in layers to construct required thickness
• A chemical resisting tissue veil applied to improve chemical resistance and prevent pinholes
• A resin wash, pigmented to the required color, applied to all areas
• The resin washed lining system is sanded to remove irregularities and debris
• A GEL Coat applied to finish the lining system

Specialist Treatment Services

Injection treatment

Polyurethane injection is extremely cost effective, in part because the procedure is uncomplicated and takes very little time. Polyurethane hardens quickly, which shortens the process even further. Hydrafoam PU is a hydrophobic polyurethane grout designed to stop water leaks. It is typically injected into cracks in concrete, honeycombed concrete, soils, pipes, pipe intrusions and other voids by use of a high pressure pump. When the liquid polyurethane meets water or moisture it reacts with it and then expands, creating a dense, closed cell foam through which water will not pass. In an unconfined environment the expansion rate of the material is 20 times its own volume.

Wet area treatment

Two part acrylic modified cementitious coating for protecting concrete structures against water, vapor, ingress of chloride ions, attacks of acidic gases and alkalis. It cures to form a tough flexible coating having excellent waterproofing properties. Single component, elastomeric, acrylic waterproofing and protective coating forms a tough, flexible and durable coating resistant to UV and other weathering agents.

Foam concrete

Lightweight concrete has extreme importance to the construction industry. It includes an expanding agent that increases the volume of the mixture while giving additional qualities such as lessened dead weight. It is lighter than conventional concrete. Its main specialties are low density and thermal conductivity, with advantages including reduction of dead load, faster building rates and lower transport and handling costs.

Pile head treatment

The Pile Head Treatment is the final working step of a successful piling and foundation system. Every pile has to be protected against chloride and sulphate attacks on the reinforcement caused by the soil and groundwater. It also has to assure that there will be no passage of water from the ground to the substructure. A properly designed system includes re-profiling, waterproofing and full encapsulation of the entire pile head.
