Helpful definitions and frequently asked questions

Whether you’re new to this industry, need some refreshers or just want to learn more, here are some definitions and examples of some of the work and service we provide.

Cold Cutting

Cut pipe without the use of heat, open flames or producing a spark.

Dry Ice Blasting

Is a form of carbon dioxide cleaning, where dry ice, the solid form of carbon dioxide, is accelerated in a pressurized air stream and directed at a surface in order to clean it.

Hydro-demolition (hydro demolition, hydroblasting, hydro blasting, waterblasting, waterjetting)

High pressure water technique, removes concrete that is deteriorated or sound concrete, as well as grout and asphalt.

Example of hydro demolition in a tunnel in Hawaii


Hydrolase is a class of enzyme that is commonly used as biochemical catalysts that use water to break a chemical bond.

Hydro-scarification (Hydro scarification, scarification)

Used for concrete bridge or road surfaces, this technique uses high pressure water to remove the top surface to create bonding for new, sound concrete.

Remove old laminates without chemicals and without harming the aluminum or corrosion resistant coatings

Inconel is a family of austenitic nickel-chromium-based superalloys.

Inconel alloys are oxidation-corrosion-resistant materials well suited for service in extreme environments subjected to pressure and heat.

Water Jet (waterjet, water jet cutter)

A water jet cutter, also known as a water jet or waterjet, is an industrial tool capable of cutting a wide variety of materials using a very high-pressure jet of water, or a mixture of water and an abrasive substance.

Waterjet cutting is often used during fabrication of machine parts. It is the preferred method when the materials being cut are sensitive to the high temperatures generated by other methods. Waterjet cutting is used in various industries, including mining and aerospace, for cutting, shaping, and reaming.

Power Washing (pressure washing)

Is the use of high-pressure water spray to remove loose paint, mold, grime, dust, mud, chewing gum and dirt from surfaces and objects such as buildings, vehicles and concrete surfaces.

Shotcrete, or sprayed concrete is concrete or mortar conveyed through a hose and pneumatically projected at high velocity onto a surface, as a construction technique. It is typically reinforced by conventional steel rods, steel mesh, or fibers.

Shotcrete is usually an all-inclusive term for both the wet-mix and dry-mix versions. In pool construction, however, shotcrete refers to wet mix and gunite to dry mix. In this context, these terms are not interchangeable.

Shotcrete is placed and compacted at the same time, due to the force with the nozzle. It can be sprayed onto any type or shape of surface, including vertical or overhead areas.

Sound Concrete

Free of structural flaws, will not crack under excessive usage


Dry mix

Water Blasting

Also known as Hydrocleaning, which uses high pressure water for cleaning.
