When we talk about surface preparation we are primarily referring to the roughing up of concrete using a rotary nozzle. The preparation can be carried out to varying finishes (levels of roughness) as required for each specific project. This can range from removing 2-3mm of laitance, to removing enough concrete to expose the aggregate. Our operators have years of experience carrying out surface preparation and have therefore developed the skills necessary to achieve whichever finish is required by the client.
In addition to the capability of our operators, we are also able to offer surface preparation using Ultra High Pressure Water Jetting. Our UHP unit is capable of operating at 2800 BAR using 20lt / min and is excellent for preparing concrete surfaces for mesh and overlay systems or for creating a key for bonding to new concrete. This technology allows us to prepare more surface area per shift than ever before meaning shorter programme periods and reduced costs for our clients.
The UHP unit was first used on a project in Guernsey in early 2014, preparing concrete surfaces to the underside of a jetty. We started the project using a 1500 BAR unit using 50lt / min and the production and finish provided were both of an acceptable level. However, once the UHP unit was introduced the production on the project doubled and the finish provided was actually preferred by the client.
At Sabre Jetting Services, we are constantly looking to develop our equipment in order to offer our clients the most comprehensive and efficient service possible, utilising the most appropriate techniques for the tasks at hand.
