A Safer, Smarter Way to Remove Concrete

Concrete Hydro Demolition

By eliminating mechanical impact and introducing water, hydro demolition bypasses the mode of entry and potential damage from silica by preventing the creation of respirable dusts.

Hydro demolition is an advanced method of concrete removal that uses high‑pressure or ultra‑high‑pressure water jets to selectively break down and remove damaged or deteriorated concrete. Unlike traditional jackhammering or mechanical demolition, hydro demolition does not rely on impact or vibration. Instead, the pressurised water penetrates the pores of the concrete, separating it from the reinforcing steel without causing micro‑cracks or structural damage.

Why It Matters: Preventing Silica Exposure

One of the most significant advantages of hydro demolition is its ability to greatly reduce the generation of respirable crystalline silica dust. This type of dust, created when concrete is mechanically cut, drilled, or broken, can pose serious long‑term health risks, including lung cancer, silicosis, chronic obstructive pulmonary disease (COPD), and other respiratory illnesses. Because hydro demolition uses water as the cutting force, the process:

Eliminates airborne silica particles at the source
Prevents dust from becoming airborne, as debris remains saturated
Provides a cleaner, safer work environment for crews and bystanders
Supports compliance with strict occupational health regulations relating to silica exposure

Benefits

Increased productivity compared to traditional concrete deterioration methods

Ultra high-pressure hydro demolition accelerates concrete removal and surface prep, cutting project time. A single Hitech robotic machine matches the output of 10–12 jackhammers, removing about 0.3 cubic meters per hour.

Ability to remove concrete and surface membranes in a variety of situations

Ultra high-pressure hydro-demolition, using handheld lances or robotic machines, works on horizontal, vertical, and overhead surfaces, unlike traditional methods limited by safety risks and inaccessibility.

Superior surface bonding characteristics

Ultra high-pressure hydro-demolition creates a rough surface for superior bonding, outperforming jackhammers and sandblasting. Tests show up to 50% stronger adhesion than mechanical methods.

Reduced emissions and water reuse

Ultra high-pressure hydro-demolition reduces noise and adapts to various job-site conditions, including bad weather. Water used can also be filtered and reused.

Eliminates concrete micro-fractures

Ultra high-pressure hydro-demolition is vibration-free, preventing rebar loosening and microfractures in surrounding concrete. Pressure levels adjust based on surface conditions.

Selective concrete deterioration

Ultra high-pressure hydro-demolition precisely removes weak concrete while preserving rebar, offering greater accuracy than jackhammers.

Reinforcing bar is cleaned without damaging the structural integrity

Ultra high-pressure hydro-demolition precisely removes concrete, exposing rebar while eliminating rust and scale without damage.
