What our german customers say:

Berliner Wasserbetriebe plays it safe!

Water is precious and should reach consumers safely. Quality and reliability are top priorities for the company "Berliner Wasserbetriebe".

"Berliner Wasserbetriebe" therefore uses the HMP SON for error-free and fast evaluation of dynamic probing.

Dynamic probing acc. to DIN EN ISO 22476-2 is used for subsoil investigation and provides information about the bulk density of the existing soil layers. It supplies important hints on excavation resistance and possible settlements. Logging and evaluation of the measured values by means of HMP SON provides enormous advantages compared with the manual method. Subjective errors by the examiner during logging and evaluation can be avoided and costs + time will also be reduced.

Cost and time savings > community Gemünden and Homberg use HMP LFG

Public authorities/institutions use LFG to save money

Again and again, communities need to repair brokenup road surfaces, eliminate the consequences of water pipe leakages and carry out the necessary roadway renovations. In case that this is a classified roads, in other words a roadway for which maintenance the federal state or province is in general responsible, the responsible supervisor requires a professional proof regarding proper compaction of the filled up area or rather proper restoration of the road surface.

Until now in communities it was only allowed to be done by specialized companies, because they have to have special test equipment. This increased the costs, especially because the construction works could normally not be carried out self-operated by the building yard, but also a subcontracting was necessary.

By means of their own dynamic plate load tester, decisions and proofs for construction works can now be made even faster and cheaper.

Magdeburg Cathedral Square shines in a new splendor

"With the redesign of the Magdeburg Cathedral Square we have breathed new life to this venerable place," said Mayor Lutz Trümper during the opening ceremony.

In order that this beautiful sight is not clouded, the executing construction companies did not renounce on quality assurance measures. For this reason the executing company STRABAG examined the bearing capacity of the substructure by using the dynamic light weight deflectometer HMP LFGpro, for preparation of the paving construction work on the Cathedral Square.

HMP PDG - used for harbour development

In Magdeburg harbour, on the Steinkopf Island, the Static Plate Load Tester HMP PDG is currently being used by Mr. Lutz Paulinus in order to assess the deformability and bearing capacity of the soil by means of the determined load settlement lines.

The company baulab Ingenieure Magdeburg relies on HMP testing technology for more than 20 years. Also the Light Weight Deflectometer HMP LFG, the soil density meter HMP DEN and a pneumatic penetrometer belong to the company equipment park.

As part of the track bed renewal a new barrier-free stopping point in front of the zoo in Magdeburg is also being set up. The congestion at this point (the connection between industrial zone and urban zone) is enormous. Therefore specific attention is paid on quality assurance in order to avoid damages to the road caused by subsidence.

- for 15 years in use now

"We just gave our device to its annual calibration. The fact that the Light Weight Deflectometer is now also available with GPS is indeed great, but in fact it just has to measure quickly and accurately!" says Mr. Fiedler - shown here while testing the compaction of a filling above a newly installed sewage pipe.

If the filling is compacted insufficiently, the pavement above could subside later and this would lead to costly guarantee claims. By performing the dynamic plate load test the proof of quality can certainly be documented and additional costs can be avoided.

First light weight deflectometer HMP LFG 0002 still works properly – after almost 22 years of continuous operation!

First HMP LFG – in use for 22 years!

The first HMP LFG was sold according to new Engineering Code in October 1992 and still works properly – after almost 22 years of continuous operation!

Mr. Christian Recklies (engineer at the “PGI Planungsbüro Geohydrologie, Grund- und Ingenieurbau GmbH, Magdeburg) just received it here recently cleaned and calibrated.

Due to tradition construction quality is a top priority for Kern-Haus.

“The most important prerequisite for carried out work is the craftsmanship. Already in 1994 the 5-phases TÜV inspection during the construction phase was implemented at Kern-Haus. In that way Kern-Haus records a maximum and uncompromising performance for the building owners and already set high standards for the  whole sector at an early point in time. Additional voluntary quality assurance offers the most security possible to our building owners. Even before pouring the concrete floor slab, the foundation stability is being evaluated by means of the Light Weight Deflectometer HMP LFG to make sure that this house has a solid basis.”

HMP LFG’s are indestructible

- After 20 years in use ICP makes demand of the replacement event “Old for New”

Reliable technics and quick service are of enormous importance for us for being able to perform all our daily tasks. Testing devices are working materials for us! For more than 20 years we count on that everything works without problems with HMP. Today we are sending our first Light Drop-Weight Tester HMP LFG (year of manufacture 1992!) into retirement and in exchange we are taking a HMP LFG-SD of the latest version into our inventory.”

HMP LFG Light Weight Deflectometer determining the compaction quality

HMP LFG - Quality assurance in road construction

"As the branch manager of the Peter Gross GmbH & Co.KG in Pfungstadt I attach particular importance to the quality of our building constructions. When determining the compaction quality I count on the measurement results of our Light Drop-Weight Tester HMP LFG. The trials take only about 2 minutes and on the basis of these results I immediately can decide how to continue with the corresponding construction project. This helps me to save costs and provides security to my contractor, because all measurement results are immediately documented at the site. One of our device is already in use for more than 15 years and still works without any problems!"

STRABAG

"On my construction sites I have four Light Drop-Weight Tester HMP LFG in use. Depending on the progress of the construction their usage is coordinated. This helps me to save a lot of costs and time, because Static Plate Load Tests are very complex. For major construction projects we determine the correlation values of the measured values of the Static Plate Load Tests and in that way we are able to prove the even compaction within a short period of time at many measuring points. Our oldest device is from the year 1993 and still used every day!"

HMP LFG Dynamic Plate Load Tester on our track construction sites for quality assurance

HMP LFG - Use in track construction

"Especially in track construction the bearing capacity of the ground has to be ensured. Therefore we at MHB are going the safe way and use Dynamic Plate Load Tester on our track construction sites for quality assurance.With this it is possible to determine the compaction quality quickly and easily, even between the sleepers. So that I as a site foreman can immediately decide, if f. e. a soil exchange is necessary. On our sites we have 2 Light Drop-Weight Tester HMP LFG interchangeably in use. The handling is really very easy."

Self-monitoring in garden and landscape construction

"We are a gardening and landscaping company in Bielefeld. In accordance with the drafts and plans of leading garden and landscape architects, we perform the execution of the complete outside facilities, including all ancillary trades. A modern and considerably large machinery is at our trained employees disposal. This ensures a smooth service, shortens construction times and enables us to complete the works on time. The quality of the construction works is our foremost goal. In order to for example avoid subsidence damages of our paving works, we test the soil stability by means of the Light Drop-Weight Tester HMP LFG before construction starts. For self-control it is only a small effort and offers us and our customers assurance."
