High-pressure waterblasting and abrasive sandblasting for pipe interiors, concrete surfaces, tanks, and industrial equipment — performed by Allied All-City's own crews across Long Island.
Every waterblasting and sandblasting job is handled by Allied All-City's own trained crews — never handed off to outside contractors.
Licensed to work on Long Island municipal infrastructure, commercial facilities, and industrial sites in Nassau and Suffolk Counties.
Decades of hands-on industrial cleaning work means our crews know how to protect surfaces while still delivering full clean results.
Industrial cleaning emergencies don't follow business hours — Allied All-City is available around the clock when you need us fast.
Proper surface preparation directly affects how long coatings, linings, and repaired components last — cutting corners here costs significantly more down the road.
Every benefit above is delivered on every job we take.

We evaluate the surface condition, substrate type, and project specifications to determine whether waterblasting, sandblasting, or a combined approach is appropriate.
Our crew mobilizes the correct equipment, establishes containment for waste water or blast media, and protects adjacent surfaces before work begins.
We complete the cleaning pass, inspect the surface against spec requirements, and document the finished condition before handing off to the next phase of work.
Standard pressure washing equipment operates in the range of 1,000 to 3,500 PSI, which is adequate for light residential and commercial cleaning tasks. Industrial waterblasting — also called hydro-blasting — operates at pressures that start around 10,000 PSI and can reach 40,000 PSI or higher on specialized units. That level of pressure is in a completely different class. It removes industrial coatings, mineral scale, hardened concrete, rust, and heavy fouling from steel, concrete, and pipe surfaces with a thoroughness that consumer or light-commercial equipment simply cannot match. Allied All-City operates industrial-grade waterblasting equipment suited for municipal and commercial project specifications, not scaled-up pressure washers.
Yes, and this is actually one of the more common applications we handle on Long Island. Before a pipe can receive a cured-in-place lining, spray-applied lining, or any other internal protective coating, the pipe interior has to be thoroughly cleaned. Scale, rust tuberculation, root material, grease deposits, and old lining remnants all have to come out. If they don't, the new lining won't bond correctly and the investment in the lining project is compromised from day one. We use high-pressure waterblasting to clean pipe interiors as part of a preparation-to-lining sequence, and our camera inspection capability lets us verify the interior surface condition before the lining crew moves in.
We sandblast structural steel, carbon steel tanks and vessels, cast iron components, concrete surfaces, masonry, and industrial equipment fabricated from a range of metals. The approach and media selection vary depending on the substrate and the specification requirements for the finished surface. Steel structures going to coating are typically blasted to SSPC-SP6, SP10, or SP5 standards depending on the coating system. Concrete surfaces may require a lighter profile for sealers versus a more aggressive preparation for thick-film epoxy or cementitious coatings. We'll review the project specifications and substrate condition before the job to make sure the process we're using is matched to what the finished coating or repair actually requires.
Yes, containment is part of every job. For sandblasting, we establish containment to capture spent blast media and prevent it from spreading across the job site or entering drainage systems. The spent media is collected and disposed of properly — the disposal method depends on what the media contains after blasting, particularly if the surface being blasted had lead paint, coatings with hazardous constituents, or other regulated materials. For waterblasting, we manage waste water runoff containment and can coordinate proper disposal. Allied All-City's environmental division handles regulated waste disposal, which means the cleaning crew and the compliance side of the job are coordinated through a single contractor rather than two separate parties.
When done correctly by an experienced crew using the right equipment and pressure for the application, neither process damages sound base material. The key is matching the pressure, media, nozzle selection, and standoff distance to the substrate. That's a judgment call that takes real field experience to get right consistently. An inexperienced operator using too much pressure on thin-wall pipe or deteriorated concrete can cause damage — which is exactly why operator experience matters as much as equipment capability. Our crews have been doing this type of work for decades across a wide range of substrates and project types. We know how to push surfaces hard enough to get them clean without compromising the material underneath.
Yes. Allied All-City works with Nassau County and Suffolk County municipalities, water districts, and sewer districts on infrastructure maintenance and rehabilitation projects. Municipal work often has specific specification requirements — surface preparation standards, documentation, confined space protocols, traffic control, and waste disposal procedures — and our crews are experienced working within those requirements. We also work on commercial and industrial sites including manufacturing facilities, food processing plants, fuel storage facilities, and marine structures. If you have a project that requires surface preparation or industrial cleaning at scale, contact us to discuss the scope and we can outline what the process and timeline would look like.
