Coatings and Linings

We have considerable experience in utilizing a range of coating systems including epoxies, phenolics, glass flake, vinyl polymeric, polyurethanes and zinc silicates.

Metallization

Metallization of storage vessels and pipelines have also been executed utilizing plasma spray (zinc and aluminium).

Water Proofing

Waterproofing is a highly specialized aspect of building design and maintenance which is beneficial to protect your valuable building assets for decades to come. Waterproofing can best be described as the treatment of a surface or structure in order to prevent water infiltration. By properly waterproofing the below and above grade structure, you not only protect the space and its contents from costly water damage, but you also preserve the structure itself.

Apollo ISD has completed extensive repairs to many key industrial assets and landmarks within Qatar and offers clients a service that ensures results

Quality

Apollo ISD has a well-trained and highly experienced workforce which includes NACE certified and BGAS certified inspectors. We can accommodate all of our clients requirements, and strictly adhere to SSPC and NACE standards for surface preparation, installation techniques, inspection and quality control unless otherwise stated

Resinous Flooring

 Floors are an important element of many facilities, they provide:
 

  • Protection to the structure against deterioration,
  • A reliable surface for the placement of equipment
  • A non-skid surface for safe and efficient movement of personnel and machinery.
  • Clear markings for access and designation purposes

However, if your floors are not up to the task, they can also be a liability requiring frequent repair and maintenance; thereby, resulting in excess cost and downtime. That's why it is so important to choose a contractor that really knows industrial flooring...Apollo Industrial Services Division.

We identify the root cause and then match the best repair method and material, developing a systematic repair program. Apollo Industrial Services Division has a dedicated civil crew who are experienced and adhere to strict quality standards and repair procedures. We deliver the required skill, resources and technical expertise to each concrete repair project. Whether it’s:


  • Shotcrete / Guniting
  • Trowel Applied
  • Structural Repair
  • Structural Strengthening

Our crew are trained applicators and will self-perform many different forms of repair methods. Typical Applications Include:


  • Structural Slabs, Beams, Columns & Piers
  • Equipment Pads
  • Concrete Buildings, Walls & Foundations
  • Parking Structures & Basements
  • Water & Wastewater Treatment Plants
  • Sewers
  • Tanks
  • Industrial Floors
  • Retaining Walls
  • Private Villas

Shotcrete and Guniting

 Dry-Mix

Dry-mix shotcrete is a highly efficient and cost-effective way to apply concrete or mortar, for both new construction and repair. Properly applied, it's structurally sound and durable. But it requires specialized knowledge, skill and experience. It's not a job for just any contractor.

Dry-mix shotcrete can be successfully applied on virtually any surface: flat or curved, vertical or sloped, even overhead.

Apollo Industrial Services Division has been successfully applying dry-mix shotcrete since 1995, and this is still the most popular method of application. The setup can be established where access is difficult as equipment can be located up to 1000 feet from the substrate. In most applications this method is more cost effective than wet-mix as it reduces the need for cranes, forms and pumps.

Wet-Mix

Wet-mix shotcrete involves pumping of a previously prepared concrete, typically ready-mixed concrete, to the nozzle. Compressed air is introduced at the nozzle to impel the mixture onto the receiving surface. The wet-gun procedure generally produces less rebound (waste material that falls to the floor), and dust compared to the dry-mix procedure. The greatest advantage of the wet-mix process is that larger volumes can be placed in less time.

Apollo Industrial Services Division is an experienced applicator of both methods and our projects include but are not limited to:


  • Four Season Hotel Roof Domes (Drymix)
  • Doha North Sewage Pumping Station, PS70 Sump (Wetmix)
  • Doha Zoo, Alligator Pool Area (Drymix)
  • Amonia Storage Tanks, Um Said (Drymix)
  • Doha City Centre Shopping Mall, (Dry Mix)
  • Gas Recycling Project, Dukhan (Drymix

Injection, Pressure Grouting and Ground Stabilisation

Forces exerted on reinforced concrete or masonry construction buildings through initial curing, stress movement, vibration, settlement and often poor construction can lead to formation of cracks or voidage. Inevitably these will lead to water penetration and the selection of the most appropriate injection resin, grout or elastomeric bandage is where our many years of leak sealing experience are crucial.

Historically the defects listed would lead to breaking out and reinstatement or at worst complete removal and reconstruction.

Apollo Industrial Services Division offers clients a number of services each chosen to fit the specific requirements:


  • Pressure Grouting. Both chemical and cementitious grouting is carried out by Apollo ISD for filling structural voids and strengthening foundations.
  • Resin Injection. Cracks in concrete structures can often be repaired using low viscosity epoxy resins, injected under controlled pressure. This method provides a mechanical bond and restores structural integrity.
  • Leak Sealing. A specially developed extension of pressure grouting techniques provides a permanent solution to water leakage into tunnels, basements and other underground structures.

Apollo ISD often utilises these techniques in parallel to concrete repair works as generally these problems are usually inherently related in terms of root cause and end consequence for our clients. Our dedicated crew are trained applicators of a number of major manufacturers and we can offer an unbiased solution to the client’s needs.

Our approach includes:


  • Identification of the root cause
  • Selection of the most appropriate technology
  • Injection/Grout plan
  • Execution and monitoring of the works
