Welcome to the future of Blast Cleaning
Feb 11 2016Problem! How to protect the expensive wooden gymnasium floor at a prestigious Bedford School from flooding whilst using the Sika Ferrogard protection system on the concrete roof beams.
Until now pressure washing was the only effective way to remove the waxy residue left over on concrete surfaces that had been protected with Sika Ferrogard 903. It is essential to remove this residue in order to achieve a bond between the concrete substrate and subsequent anti-carbonation coatings, but pressure washing requires around 15 litres of water per minute to be effective. Over the course of several days this amounts to a lot of water, all of which is a potential threat to the wooden flooring. Concrete Renovations Ltd remedied the problem with the revolutionary Sponge Blasting method.
"Sponge blasting surely is the future of blast cleaning."
“The dry abrasive blasting qualities of sponge blasting were exactly what were required to carry out this contract,” said Graham Worraker of Concrete Renovations Ltd. “The sponge blast method removed all of the residue and was virtually dust free, this created a better working environment for all involved and the fact that all of the Sponge media was recycled during the process simplified the clear up procedure as well.”
“Sponge blasting the concrete beams was virtually dust free. We were able to achieve a better standard of preparation due to the flexibility of the equipment. There was less risk to other trades because of low rebound velocity, better visibility and virtually no dust emissions. Other benefits we found included a huge reduction in the amount of waste created as all the sponge was recycled, this reduced the impact on the environment, and reduced our overall waste disposal costs.”
