Waffle Rubber

This type of padding is still being used today but often improperly. The waffle part of the padding gives it a thickness that is mostly air, and as a result, any of this type of padding rated less than 90 ounces is still too soft for today’s plastic backed carpets. Also, despite claims to the contrary, the rubber used to make these paddings is held together with clay type binders that break down with use.
