Drill powder extraction
The problem is familiar: Water collects on sealed concrete surfaces such as in multi-storey car parks, parking decks or bridges. If de-icing salts are applied to these surfaces in winter, the salt penetrates into the concrete and attacks the reinforcing steel below.
In order to recognise how deeply the chloride has already penetrated into the concrete, and which points are particularly at risk, drill powder can be extracted from the concrete. At critical points badly affected by corrosion, we can establish the magnitude of the damage by means of a potential field survey. Through a combination of both methods – drill powder extraction and potential field measurement – we offer an economically sensible method of analysis as the potential field measurement is only carried out on the really critical points.
We carry out professional drill powder extraction to determine the chloride content in concrete at different degrees of depth. For this we use the BEG1 - a special equipement developed in-house by our company which enables the clean and uncomplicated collection of drill powder. The BEG1 can be used with all established drilling machines. To this end we have developed a new type of hollow drill bit which enables particularly high-performance drilling.*
For the chemical analysis of the drill powder we work together with a recognised laboratory partner. You receive from us a complete analysis of the results of your drill powder extraction.
