Application

Cushion Pads

Solution

Cushion pads made of TECAST 

Description

When ramming concrete piles of varying lengths into the subsurface, cushion pads are used to absorb the impact energy.

Requirement profile

  • High energy absorption
  • Good recovery elasticity
  • Balanced ratio of strength to toughness

Material chosen

TECAST mod. offers the ideal combination of toughness and strength for differing soil conditions – allowing the cushions to withstand long operating periods.
