Concrete Crushers (Hydraulic Concrete Shears) for Demolition: Where They’re Most Effective and How to Get Maximum Results
Concrete crushers (often called hydraulic concrete shears, concrete pulverizers, or simply crushers) are excavator attachments that don’t “hit” like a breaker — they crush and bite through concrete, breaking a structure into controlled fragments. In demolition, they are one of the most practical tools when you need precision, safety near existing buildings, and reduced vibration compared to a hydraulic breaker.

Using a Hydraulic Breaker for Demolition: Where It Works Best and How to Get the Best Results
A hydraulic breaker (hydraulic hammer) is one of the most powerful and practical tools in modern demolition. It’s used when manual methods are too slow, and blasting is either inappropriate or not allowed. Thanks to controlled impact force, a breaker can quickly fracture concrete, reinforced concrete, stone, asphalt, and other hard materials while keeping the process manageable and reducing risks to nearby structures.

Demolition of an FBS block foundation
What Is an FBS Foundation and Why It Needs to Be Dismantled
An FBS foundation (solid concrete block foundation) is one of the most common base types used in residential, industrial, and warehouse construction. These blocks are known for their strength, durability, and stability. However, over time, situations may arise that require FBS foundation dismantling.
Reasons include: building reconstruction, design errors, structural damage, or the need to relocate a structure. Dismantling may also be necessary during major renovations or when redesigning a land plot.

How Much Scrap Metal Hides in an Old Factory? An Appraiser’s Inside Look Before Demolition
Industrial demolition isn’t just a cost center. Inside every obsolete plant lie tons of recoverable metals that can offset—or even exceed—the teardown budget. Below is an engineer-appraiser’s view of what, where and how much value you can unlock from a typical Soviet-era factory before the first excavator arrives.
1. Steel frame and purlins: the “quick” tonnage
Workshop skeletons from the 1960s use S245 I-beams. Average steel density: 32–35 kg per m² of roof. A 4 000 m² hangar yields about 135 t of structural steel. At...
