Hydro demolition contractor in the Philippines
Dezu is a PCAB-licensed hydro demolition contractor removing damaged or excess concrete with ultra high pressure water while preserving rebar and sound structure — using both Conjet robots and precision hand lances. Six delivered projects since 2021 across railway infrastructure, power plants, petrochemical facilities, and viaducts, as the specialized subcontractor to international EPC and construction joint ventures.

Robotic or hand lance — which does your project need?
Robotic hydro demolition suits large volumes, thick sections, and continuous production — our Conjet robot removed honeycombing from a double-cell underground railway wall with 1.6 meter thick legs and 1.2 meter thick slabs. Precision hand-lance work suits confined areas, selective repairs, and smaller scopes like beam honeycombing or shear key exposure. Dezu delivers both and recommends the method after a scope review.
Why hydro demolition instead of jackhammering?
Ultra high pressure water removes damaged concrete without impact or vibration, so reinforcing steel is preserved and sound concrete is left without microcracks. The exposed surface is rough and clean, which bonds better with new concrete. For structural repairs where the rebar must survive, jackhammers create the damage hydro demolition avoids.
Is Dezu licensed for construction-classified work?
Yes. Dezu Corporation holds PCAB Contractor's License No. 56253, a DOLE-approved Construction Safety and Health Program, and is a PhilGEPS Platinum member. We work inside PEZA zones and on permitted public infrastructure.
