Demolition of Buildings & Structures

Bringing Expertise & Precision to Exploration, Estimation & Excavation

Building demolition is necessary due to many reasons like extreme damage in the existing structures, the need for an expansion of existing buildings or sometimes in case of a change in rule by the government. A number of building demolition techniques like wrecking ball, selective demolition, etc. are used to bring down the structures. Demolition by explosives, however, is one of the quickest building demolition techniques, hence preferred by many. A simple principle of weakening the fundamental support is used in order to demolish a structure. It involves a strategic placing of demolition explosives and setting up the detonation times.

Safety during demolition by implosion is a major responsibility. Safety of life of working personnel and neighbouring structures as well as being compliant with the environmental standards while executing a building demolition requires a delicate balance.

At Uttam Blastech, we are in cognition of the safety measures required during the building demolition. Therefore, we take pride in our collaboration with NITREX SRL®, a company based out of Italy, which specialises in implosion and demolition of structures that meet the European Standards of Safety and Environment. Uttam Blastech has an expertise in demolition and implosion of residential, commercial and industrial structures and buildings.

The team of experts at Uttam Blastech take care of demolition by implosion process from start to finish.

A number of modifications like removing the loose parts such as brickwork of the ground floor are carried out. Structures like balcony or canopies, which protrude out of the main building are dismantled. The preliminary dismantling helps in optimizing the final fall.

  • Supply and installation of explosives:

Uttam Blastech handles the supply of explosives from NITREX SRL®.

Implosion is planned by taking site-specific parameters into account. Further, installation of demolition explosives is executed as per the plan. The time difference between the detonation times is crucial and is set up according to the planned sequence.

  • Supervision of explosion:

The team of Uttam Blastech conducts a thorough supervision during the process of an explosion. NOMIS_Mini_Supergraph II, a vibrations measuring device is also installed in place and monitored to ensure that the vibration limits are not exceeded.

  • Handling of demolition debris and recycling:

The aftermath of a demolition is the large quantity of debris and the need for recycling the waste. Uttam Blastech takes care of this exhaustive task as well. We move the demolition debris by a fleet of heavy equipment, including excavators and loaders, onto trucks and other earthmoving vehicles. It is then carted off the demolition site to an approved recycling facility.
