GKB Drainmaster
The GKB Drainmaster was designed to aid in surface drainage with no pipe installation all in one pass. Digging 2-3 trenches up to 10″ in depth while backfilling with sand all in one pass, making standing water a thing of the past.
The GKB Drainmaster has been in development since 1985, and we have kept refining the Drainmaster since then. The system has been developed in order to improve and accelerate the drainage of surface water. The result is your grass will continue to grow in quality and become more stable.

The trenches are filled with drainage sand to the operating depth of 23 cm during the same operation. The wheels of the Drainmaster will press the drainage sand into the trenches. The sand bunker has been developed in such a way that you can operate the full length of a pitch with one operation, or you can decide to do two operations across the width of the turf.

The grass will grow on the trenches within a number of weeks. The created drainage network ensures a higher playing capacity. As a result of stronger grass, you will also experience less damage from the activities on the grass. If you combine the operations of our Drainmaster and Combinator you can create an even, well-functioning sports turf.
