FAQs
Specialized Services Frequently Asked Questions
What industrial dry ice blasting services do you offer?
We offer non-abrasive, dry ice cleaning for sensitive industrial machinery and electrical panels, cleaning in-situ to reduce downtime.
Is dry ice blasting safe for cleaning live 11kV electrical switchgear and MV/HV panels?
Yes, dry ice blasting is a completely dry, non-conductive, and non-toxic cleaning method, making it exceptionally safe for sensitive electrical infrastructure. Available to industrial facilities in Gauteng, KwaZulu-Natal, the Western Cape, and all other provinces, Alsandro Construction specializes in the precision cleaning of running Medium Voltage (MV) and High Voltage (HV) electrical panels, including 400V and 11kV switchgear. The CO2 pellets sublimate instantly, leaving zero moisture and eliminating the risk of short circuits.
How does the dry ice cleaning process work without damaging sensitive industrial equipment?
Dry ice cleaning utilizes three primary physical forces: kinetic energy, thermal shock, and gas expansion. Soft CO2 pellets are accelerated at supersonic speeds via compressed air. Upon impact, the extreme cold (-78.5°C) creates a thermal shock that embrittles the contaminant. The pellet then instantly converts into a gas, expanding 800 times in volume to lift dirt, grease, and carbon deposits away from the substrate. This non-abrasive process cleans without etching, pitting, or wearing down delicate machinery parts.
Can dry ice blasting reduce maintenance downtime in manufacturing and power plants?
Absolutely. The most significant advantage of dry ice blasting is its ability to clean industrial equipment in-situ, drastically reducing operational downtime for manufacturers across South Africa. Because the process requires little to no disassembly of machinery and generates no secondary waste streams (like sand or water) that require post-cleaning removal, facilities can often resume production immediately. Furthermore, because it is a dry process, there is zero cool-down or drying time required before equipment can be safely restarted.
Why is professional underground utility detection critical before commercial site excavation?
Underground utility detection is an essential risk mitigation strategy that prevents catastrophic damage to buried infrastructure during excavation, trenching, or horizontal drilling. Alsandro Construction utilizes advanced, non-destructive mapping technologies (such as GPR scanning) to precisely locate subterranean hazards across sites in Gauteng, the Free State, Limpopo, and nationwide before breaking ground. By identifying these hidden assets, we protect teams from strikes, prevent costly delays, avoid regulatory penalties, and ensure local communities don’t suffer utility outages.
What specific types of buried services and pipelines can your utility detection equipment locate?
Our specialized utility detection experts are equipped to comprehensively map and trace a wide array of underground networks. We accurately locate running power lines, high-voltage electrical cables, natural gas lines, and telecommunications fibre-optics. Additionally, we detect complex wet utilities, including bulk water mains, stormwater drains, and sewerage pipes. This detailed visualization and mapping process ensures that all subsequent earthmoving and infrastructure development occurs with absolute precision and safety.
