Bosch GAS 15 PS Professional
Wet and dry vacuum extractor
The Bosch GAS 15 PS Professional is a wet and dry extractor. It is the least glamorous item in this catalogue and one of the most consequential: a substrate that has not been properly vacuumed after cutting is a substrate the primer bonds to dust rather than to concrete.

Product description
Leakproofs by Betterwork specifies and applies Bosch GAS 15 PS Professional as part of a complete waterproofing system. A material on its own does not stop a leak — what stops it is the right material chosen for the right defect, on a surface that has been properly prepared. That is why we deep-scan before we specify.
Where Bosch GAS 15 PS Professional is used
This product is specified for concrete, terrace, bathroom.
- Extracting dust during crack cutting and chasing
- Cleaning a slab after grinding and before priming
- Removing standing water from a sunk slab or basement before treatment
- Site clean-down in occupied properties between visits
Suitable substrates: RCC, Concrete, Screed, Tile.
How it is applied
Connected to the cutting or grinding tool where an extraction port exists, and used to vacuum the full area before priming. Wet pick-up is used to clear standing water from areas being prepared for treatment.
Preparation is the part that decides whether the system lasts. Loose material and failed old coatings are removed, cracks are cut and filled, and the surface is cleaned and brought to the moisture condition the product requires before anything is applied. Skipping that stage is the single most common reason waterproofing fails in its first season, whichever brand is on the tin.
Key properties
- Handles both dust and standing water
- Connects to grinders and rotary hammers for extraction at source
- Removes the dust layer that stops primers bonding
- Reduces silica exposure during concrete cutting
- Essential on occupied residential sites
