The original. Taken further. grundomat p+ soil displacement hammer
Proven GRUNDOMAT technology – Taken FUTHER to meet the requirements of modern construction sites
Robust. Precise. Effective.
And now consistently refined.
For over 50 years, GRUNDOMAT has been the original in soil displacement. Construction companies, utility companies and civil engineering businesses around the world rely on its reliability, robust construction and precise operation in daily use.
With the GRUNDOMAT P+, we are building on the proven technology of the GRUNDOMAT P – and continuing to develop it in areas that really matter in practice: serviceability, wear, operational safety and handling. Optimised components, a well-thought-out design and targeted improvements to details ensure a longer service life, less downtime and better planning for everyday construction site operations.
With that the GRUNDOMAT soil displacement hammer will remain the reliable solution for demanding applications in trenchless pipe construction in the future.

Optimised head sealing – dependably tight for lasting performance
The optimised, durable head gasket reliably protects the GRUNDOMAT against dirt and particles entering the front of the housing. This ensures that the tried-and-tested 2-stroke principle continues to function perfectly, even in demanding applications.
Your benefit: Consistent performance, fewer breakdowns, and increased service life of machine and individual components (chisel and front part of the housing).
Guide bushing – precise guidance, less wear
The guide bushing, located at the front of the housing, significantly reduces wear between the bushing and the chisel. This provides stable guidance for the chisel inside the housing's front part, supporting precise and accurate work.
Your benefit: Lower maintenance costs, longer service intervals, considerably lower service costs.
Wear indicator – machine condition at a glance
The wear indicator allows you to check the condition of the housing quickly and easily. Maintenance needs are identified early on – without the need for time-consuming inspections.
Your benefit: Better planning in everyday work, greater operational reliability and, ultimately, avoidance of unplanned downtime.
Service-friendly design – back in operation faster
The GRUNDOMAT P+ features a screw-in front housing that makes servicing and maintenance much easier. Wear parts, such as the head and chisel, can be replaced quickly and cost-effectively
without dismantling the entire machine.
Your benefit: Shorter service times, noticeable cost savings, carrying out simple servicing work yourself.
Crowned head – the right choice for challenging soils
For hard and heavily compacted soils, the GRUNDOMAT P+ is also available with the proven crowned head, ensuring higher installation speed and accuracy.
Your benefit: More ground penetrating power, improved accuracy and greater success with demanding construction jobs – a noticeable increase in productivity.
