When buildings and structures are extended or converted, the foundations often
have to be reinforced or enlarged.

 

Sleeve pipes are inserted into the ground to achieve this. These pipes are used
to grout the free pore volume with cement, microfine cement or plastics in
stages. This produces a homogeneous body that can carry the necessary loads.

 

By means of ground stabilisation and injection of cement and solid material,
subsided building structures are underpinned, secured and then raised again.

Amongst other things, cements, microfine cements, PU resins or gels are
implemented as injection materials.

A compressive strength of > 50 N/mm2 was achieved for this case of ground
stabilisation with a rigid PU resin system.
