Injecta Fire Barrier successfully installed injectaclad in just 9 weeks 

The brief

City Gate Construction approached Injecta Fire Barrier to undertake a remediation project at an apartment block in Newton Abbott. The brief was to create a cavity barrier between apartments in line with current building regulations enhancing the safety of occupants in the event of a fire. Using the patented Injectaclad system, there was no need to remove the building facade. This significantly reduced both the project costs and timescale to achieve the new standards as detailed in Fire Safety Act 2021 following the Grenfell disaster.

In 2022, the Government announced an agreement with developers to contribute a minimum of £2 billion towards cladding remediation on their buildings of 11 to 18 meters. This resulted in many building owners seeking cost effective solutions that are regulatory compliant and cause minimal disruption to protect their buildings from fire.

It is possible to use MEWPs for access, however in this instance, scaffolding was erected around the building. Small openings were made to the external walls at 2 metre centres, to gain access to the cavity.

Injectaclad was pumped both horizontally and vertically into special ‘socks’ that sit in the cavity supported by steel pins. The material contained in these socks is considered as an intumescent or reactive material. On contact with heat it expands approximately 25 times its size, forming a barrier to fire and smoke containing the disaster to where it started allowing time for occupants to safely exit the building. The holes in the external walls are made good.

The Solution

Example shows sock filled with Injectaclad inside a wall cavity. When heated, the material expands to 20-30 times it’s size to fill voids created by fire, preventing fire from spreading throughout the building.

The Result

The exterior of the building was newly rendered and the project was completed in a far reduced timescale when compared with traditional remediation methods.
