Bosch GBH 2-26 DRE Professional
Rotary hammer
The Bosch GBH 2-26 DRE Professional is an SDS-plus rotary hammer used for cutting out cracks, chasing and opening up concrete. Most waterproofing that fails early fails on preparation, and cutting a crack to a proper profile is preparation work that a drill cannot do.

Product description
Leakproofs by Betterwork specifies and applies Bosch GBH 2-26 DRE 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 GBH 2-26 DRE Professional is used
This product is specified for cracks, concrete, bathroom.
- Cutting out cracks to a V or U profile before filling
- Opening a bathroom sunk slab for inspection or repair
- Removing failed brick-bat coba and old screed from terraces
- Chasing for injection ports before grouting
- Cutting back spalled concrete to a sound edge
Suitable substrates: RCC, Concrete, Masonry.
How it is applied
Used with the correct SDS-plus chisel or bit for the task, and with dust extraction on any occupied site. Cracks are cut to a consistent profile rather than merely widened — an irregular groove holds filler unevenly and cracks again along the thin points.
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
- Hammer, rotary hammer and chisel-only modes
- SDS-plus chuck for fast bit changes
- Suited to crack cutting and concrete opening-up
- Accepts dust-extraction attachments
