When polyurea alone isn’t enough — we bring all the supporting layers too: concrete restoration, sandblasting, industrial epoxy, and more.
Sandblasting is the classic foundation for any quality industrial coating project. It removes rust, old coatings, and contamination, and creates a controlled roughness on the metal that maximizes the adhesion of the new coating. We work to SSPC-SP10 (Near White Metal) and Sa 2.5 standards — the highest in the industry.
After sandblasting, we apply multi-layer industrial paint systems using advanced chemistries: epoxy, polyurethane, or polyurea — according to the project’s specific requirements and the environment in which the facility will operate.
On projects where the plant or building cannot be shut down — and adding dust to the air is unacceptable — we work with a vacuum blasting system. The abrasive particles are shot at the surface and immediately collected back into the machine along with rust and old coating. No dust in the air, no need to wrap the area, and we can work in a hospital, a food plant, a shopping mall, or any other sensitive environment.
It’s one of the most sought-after technologies in Israel — and very few contractors have it. Anaf is one of the few providers in Israel that owns the professional equipment for this kind of work.
Negative-side sealing is the most challenging waterproofing case: water enters from the inaccessible side — meaning we’re working on the inner side of the wall or floor, while water is being pushed in through the concrete from outside. In this situation, conventional external sealing isn’t possible, and a special method is required.
Our approach: injecting active acrylic or polyurethane materials into the cracks and voids behind the wall. The material reacts with water and expands, forming a hermetic barrier inside the concrete itself. After injection, we can also apply a front-face polyurea seal for a perfect, decades-lasting result.
This method is mainly needed in underground machine rooms, underground parking, building basements, and the sealed sections of elevator shafts.
When the concrete substrate is damaged — large cracks, crumbling sections, exposed rebar — you can’t just spray a coating over it. You first have to restore the concrete itself. We specialize in industrial sprayed restoration concrete to EN 1504 standards, in stages:
Typical projects: bridge support columns, retaining walls, marine structures, sewage basins, and older industrial buildings that need infrastructure upgrade.
Asbestos and iskurit (corrugated steel) roofs on older industrial and commercial buildings suffer from a range of problems: leaks at bolt points, rust in steel panels, cracks, and peeling paint. Removing the roof is usually complex, expensive, and requires hazmat handling. Sealing and coating the roof with a polyurea system is an excellent alternative — extending its life by 15–20 years at a fraction of the cost of removal and replacement.
The method: cleaning the roof, treating bolts and joint points, anti-corrosion painting, and finally a continuous polyurea layer that covers the entire roof as a single unit. The result is a brand-new roof without shutting down the plant for a single workday.
In certain situations polyurea isn’t the ideal solution — for example, in food plant floors, pharmaceutical labs, or underground parking. In these cases, industrial epoxy is usually the right choice. It creates a strong, perfectly flat, clean, low-maintenance surface.
We apply epoxy systems to international standards: thin-film finishing epoxy, self-levelling epoxy for aesthetic, perfectly flat surfaces, and quartz-filled epoxy for high-load environments. Every system includes primer, intermediate layer, and topcoat with additives as needed — such as anti-static, low-slip, or high chemical resistance.
