A spring force is a contact force not a non-contact force.
contact force:when two objects are in contact with each other it is called contact force.non-contact force:when two objects are not in contact with eachover
Magnetic force is a non-contact force.
It is a non-contact force - no contact is required for the force to act.
non contact
Here are technical definitions for the two: Contact Grouting is the filling of voids between a structure (typically a lining) and the host geologic material. Consolidation Grouting is the filling of rock discontinuities. As far as your question concerning the consumption rate of cement for contact grouting it is dependent on numerous variables, the lining method, the quality of the lining, the grouting pressure, the grouting refusal criteria, the timing of the grouting, etc.

Grout is a material used to fill voids in concrete or tile structure. Grouting or Injection Grouting or Pressure Grouting invariably means the process of injecting grout into isolated pores or voids in a concrete or tile structure.Eg:- Injection grouting in a concrete water storage tank.
Grouting brush is a cleaning supply used to clean tiles.
Latex paint can stick to the floor grouting.
What is composition of cement and any other metrial for grouting on floor ceramic tiles.
cement grouting is the process of injecting the cement slurry in to the engineering structures to stabilize the structure.

The Grouting Intensity Number (GIN) involves the energy expended, which is grouting pressure P, and the grout volume injected V. The product PV is called the Grouting Intensity Number or GIN. The volume may be unitized to the length of the grouting intervals as liters/m (or interchangeably as weight of cement injected in kg/m, since for moderately thick mixes the numerical values are similar within 5 to 10 percent). The pressure has been used traditionally as bar, resulting in P-V or GIN units being bar liter/m
Curtain grouting is carried out to make the rock mass less permeable at a given line (or two or three parallel rows). Depth of grout curtain holes vary from a few meters to more than 150 m. Consolidation grouting aims to improve rock mass (foundation) strength, permeability and reduce its deformability and executed in an area rather than a line. Usually, grout holes for consolidation grouting are less than 15 m deep.
