Can Ultralight be used under heavy loads such as a car?

Although it would depend on the total point load (aka ground pressure), the answer is no. Warmup’s Ultralight was designed to be used in foot-traffic applications only.

Point loads greater than Warmup’s Ultralight Compressive Strength (10% Compression) of 32 psi (220 kPa) may cause a future failure. Warmup recommends a rigid foam that meets the specifications for heavy-point load applications.
