Concrete demolition with Ketrak : What does it mean? Concrete’s high strength makes it one of the hardest materials to demolish, making the correct method essential. Concrete demolition with Ketrak is one of the safest, most precise non-explosive demolition methods , separating concrete controllably without severe vibration, excessive noise or damage to surrounding structures. Many civil engineering and building projects therefore use Ketrak concrete demolition for its safety and quality.
What Is Concrete Demolition with Ketrak?
Ketrak concrete demolition means breaking concrete or rock without explosives. Contractors drill holes and fill them with Ketrak mixed with water. After several hours, Ketrak expands, exerting very high pressure on the hole walls so the concrete cracks and separates controllably.

Ketrak Application Services for Concrete Demolition
Ketrak services from Mahtecsa provide a specialist solution for demolishing various concrete structures without explosions or severe vibration, enabling controlled concrete demolition in building, industrial and civil engineering projects. Ketrak demolition is applicable to reinforced concrete, foundations, floors, walls and concrete structures , each using specific procedures and protocols:

Reinforced Concrete Demolition with Ketrak
Reinforced concrete demolition with Ketrak breaks concrete containing rebar without explosives. In this Ketrak concrete demolition method, the material is poured into drilled holes. The Ketrak demolition agent creates expansive pressure and controlled cracking. Once concrete breaks, remaining reinforcement is separated using hydraulic shears or cutting tools .
Concrete Foundation Demolition with Ketrak
In Ketrak concrete demolition services, holes are drilled in the foundation and filled with Ketrak. The Ketrak demolition agent creates very high expansive pressure, cracking and breaking concrete from within. This Ketrak concrete demolition method is highly suitable for thick, strong foundations without explosives, with minimal vibration and surrounding damage.
Concrete Floor Demolition with Liquid Agents
After concrete drilling, concrete demolition liquid or Ketrak mortar is poured into holes. Gradual expansion cracks concrete from within and breaks it without explosions or severe vibration. This Ketrak demolition method for concrete floors is suitable for buildings, factories and industrial yards because it minimizes surrounding damage.
Concrete Wall Demolition with Concrete-Removing Acid
Demolishing concrete walls with concrete-removing acid is not possible. These acids only dissolve thin concrete layers or dried cement on surfaces and equipment. Walls require methods such as concrete cutting, concrete demolition agents such as Ketrak or hydraulic breakers.
Concrete Structure Demolition with Ketrak
For Ketrak concrete demolition services, holes are first drilled in the specified structural areas and filled with Ketrak. The material gradually expands, exerting very high pressure on the concrete. The concrete demolition agent then cracks and demolishes the structure controllably without explosions, severe vibration or surrounding damage.
Concrete Demolition in Confined Spaces with Ketrak
For Ketrak concrete demolition in confined spaces, holes are drilled and filled with Ketrak, whose gradual expansion cracks and breaks concrete from within. Without explosions, severe vibration or flying debris, this is a safe, suitable option for enclosed spaces, basements, tunnels and limited-access locations.
Why Is Ketrak Used for Concrete Demolition?
Concrete demolition with Ketrak is suitable for many projects because it cracks and breaks concrete controllably without explosions, severe vibration or excessive noise. It is therefore safe and precise where surrounding structures must be protected or explosives cannot be used.

Factors Affecting Ketrak Concrete Demolition Prices
Ketrak concrete demolition prices vary according to several factors, particularly project parameters and the quantity of concrete demolition agent, or Ketrak used. Different factors determine Ketrak concrete demolition prices , including concrete thickness and strength, work volume, hole quantity and depth, Ketrak consumption and site access. Harder concrete and more complex projects increase duration, material consumption and demolition costs.

- Higher costs in some projects: Mechanical methods may be more economical for small or simple demolition projects.
How to Use Ketrak for Concrete Demolition
The Ketrak concrete demolition procedure includes proper drilling, preparing Ketrak mortar and placing it in the holes. Correct water ratios, specified hole depth and spacing, and ambient temperature directly affect demolition quality and speed.

Concrete Drilling and Site Preparation
Specialists define the Ketrak demolition area and drilling points to provide suitable locations, depths and spacing. This preparation distributes Ketrak’s expansive pressure evenly through the concrete, directing cracks along the intended route and improving precision, safety and efficiency.
Preparing and Mixing Ketrak for Concrete Demolition
For concrete demolition with Ketrak, specialists mix the material with a specified water quantity to activate the required expansion. They pour the mixture into concrete holes so the Ketrak demolition agent gradually expands, creates high pressure and cracks the concrete controllably.
Placing Concrete Demolition Ketrak in the Holes
At this stage of Ketrak concrete demolition services, specialists prepare the agent and slowly pour it into the holes until completely filled. This allows the Ketrak demolition agent to expand uniformly, exert the required pressure and create controlled cracks.
Allowing Time for Cracking and Demolition After Ketrak Placement
After pouring Ketrak into the concrete holes, specialists wait for gradual expansion and pressure buildup. Concrete cracks controllably and becomes ready for separation and final demolition.
How Long Does Ketrak Concrete Demolition Take?
For Ketrak concrete demolition services, duration depends on concrete thickness and strength, ambient temperature and Ketrak type. Initial cracks generally appear within 2–12 hours, while complete demolition may take 24 hours or longer. The more suitable the Ketrak concrete demolition conditions and the more closely technical instructions are followed, the faster and more effective the material becomes.
How Is Reinforced Concrete Demolished with Ketrak?
For reinforced concrete demolition with Ketrak , specialists first drill holes to specified depth and spacing and fill them with Ketrak. This concrete demolition agent gradually expands, cracks concrete and separates it from reinforcement. Remaining bars are then cut using suitable tools such as hydraulic shears or cutting equipment , because Ketrak only demolishes concrete and does not cut rebar.
How Ketrak Works in Concrete Demolition
During Ketrak concrete demolition, the material, mixed with water, gradually expands inside the drilled holes, exerting very high pressure on internal walls. This creates controlled cracks and separates concrete without explosions, severe vibration or surrounding damage.
Ketrak Compared with Explosives and Traditional Concrete Demolition Methods
Unlike explosives, Ketrak and many traditional methods differ in that Ketrak uses expansive force without explosions, severe vibration or excessive noise. Specialists therefore use Ketrak concrete demolition services for projects requiring high precision, greater safety and protection of surrounding structures and services .
