ST JAMES HOSPITAL
St James Hospital - Leeds.
Complete Blasting Services were contacted by Sir Robert Mcalpine to carry out a specific design feature for the new Hospital wing.
The scope was to shot blast the newly poured concrete walls removing only the top skin revealing a raw aggregate design with a visible textured finish.
The concrete area had been designed by the architects of London never done before in a Hospitals surroundings.
After several site visits testing out different abrasive products, grades and pressures we were able to achieve the perfect requirement.
Using a medium grade recycled glass abrasive we found the product was achieving the best quality finish.
Due to shot blasting within the grounds of a live working Hospital Health and safety requirements meant the works planned had to be extremely protective of the surroundings.
Due to the multiple obstacles shot blasting can produce with Dust, Noise and flying abrasive we had to provide safe and effective solutions for all possible hazards.
The Process.
*Dust: Attaching a water fed nozzle to the blast hose mixes a continuous flow of water into the abrasive mid air causing a dust suppression method,
This reduces dust up to 95% compared to blasting without water.
After each working day the walls were jet washed down removing the wet slurry caused by the wet blasting method leaving behind a clean finish.
*Noise: Due to high pressure air flow the blasting work creates a loud whistle this was reduced by surrounding the working areas with a sound dampening acoustic barrier supplied and erected by CBS.
Whenever blasting our team put in place safe distance exclusion zone's and protective barriers ruling out any possible hazards.
CBS Made the whole project hassle free for the clients by re assuring and testing for all safety requirements.
Works completed in September 2018 . Project value £21,000.
