The com­pa­ny Stitz is a lea­ding spe­cia­list in geo­tech­ni­cal and soil inves­ti­ga­ti­on equip­ment. For gene­ra­ti­ons, we have been desig­ning and manu­fac­tu­ring field-proven soil mecha­ni­cal devices. Our broad and reco­gni­zed range offers a varie­ty of pro­ducts that meet the hig­hest qua­li­ty stan­dards.

The com­pa­ny was foun­ded by Kurt Stitz in 1961. In the early days, pre­cis­i­on mecha­ni­cal auto­ma­tic turned parts were manu­fac­tu­red. The pro­duc­tion quick­ly expan­ded into new areas. Due to the sub­stan­ti­ol growth, the pro­duc­tion site in Benthe became too small. In 1977, the pro­duc­tion was relo­ca­ted from Benthe to a new com­pa­ny buil­ding in Gehr­den.

Deve­lo­p­ments in mea­su­ring instru­ments in soil and rock mecha­nics fol­lo­wed.

Force trans­du­cers
Devices for mea­su­ring and moni­to­ring ten­si­le forces.

Uni­ver­sal length mea­su­re­ment devices for moni­to­ring move­ments in under­ground con­s­truc­tion.

Bore­hole defor­ma­ti­on probe
Used to deter­mi­ne static and rheo­lo­gi­cal rock and moun­tain data.

Mea­su­ring instru­ments
Elec­tro­noc dis­play and eva­lua­ti­on devices. Direct­ly rea­da­ble strains, length chan­ges, pres­su­res, and forces.

With the chan­ges and demands of the indus­try and equip­ment, we have also grown and con­ti­nu­al­ly ven­tu­red into new areas.

Window sam­pling
Inclu­ding per­cus­sion window sam­pler and hydrau­lic pul­ling devices for coll­ec­ting infor­ma­ti­on about soil com­po­si­ti­on and struc­tu­re.

Dyna­mic pro­bing
Inclu­ding dyna­mic pneu­ma­tic pene­tro­me­ter used to mea­su­re pene­tra­ti­on resis­tance in soil inves­ti­ga­gi­on pro­ce­du­res.

Soil inves­ti­ga­ti­ons
Various field devices such as hand drills for obtai­ning soil mate­ri­al to deter­mi­ne the con­tent of mine­ral nitro­gen (Nmin).

Water sam­pling
Dif­fe­rent water sam­plers for obtai­ning water samples for ana­ly­sis, for exam­p­le, con­ta­mi­na­ti­on spread.

In 1997, Dipl.-Ing. (FH) Micha­el Stitz-Maack was appoin­ted as the mana­ging direc­tor. Under his entre­pre­neu­ri­al lea­der­ship, signi­fi­cant pro­duct and tech­no­lo­gy inno­va­tions were imple­men­ted.

Deve­lo­p­ments and manu­fac­tu­ring of mea­su­ring instru­ments, as well as addi­tio­nal manu­fac­tu­ring and dis­tri­bu­ti­on areas for soil inves­ti­ga­ti­on equip­ment and geo­tech­ni­cal devices, fol­lo­wed.

Thanks to a well-estab­lished, loyal, and qua­li­fied team, we are able to carry out various manu­fac­tu­ring steps in-house.

In 2018, Henrik Maack M.Sc. was appoin­ted as the addi­tio­nal mana­ging direc­tor and ensu­res that we can con­ti­nue to offer our cus­to­mer relia­ble and cost-effec­ti­ve pro­ducts in the future.

Our goal is to offer our cus­to­mers not only inno­va­ti­ve pro­ducts but also tailor-made solu­ti­ons. Inge­nui­ty and well-foun­ded cus­to­mer know­ledge are cru­cial in this endea­vor. We engage deeply with the indi­vi­du­al requi­re­ments of our cus­to­mers to deve­lop the right solu­ti­ons. Our cus­to­mers app­re­cia­te our exper­ti­se as well as our relia­bi­li­ty, and they have trus­ted us for many years.

We take pride in being an estabi­lished com­pa­ny in the indus­try. In the future, we look for­ward to con­ti­nuing suc­cessful col­la­bo­ra­ti­ons with our cus­to­mers.
