Appeal No. 2001-2357
Application No. 09/093,185
1. A waterproofing laminate material free of loose particulate
material consisting essentially of:
a flexible, porous carrier sheet laminated to a waterproofing
sheet which is formed by extrusion under vacuum from a
substantially homogenous [sic, homogeneous] deformable mass
consisting of a mixture of particulate smectite clay and a
liquid, in which respect the clay is in a range from 50% to 75%
by weight of the mixture and the liquid comprises water in a
range from 10% to 30% by weight of the mixture.
15. A method of making a waterproofing laminate material
consisting essentially of the steps of mixing a particulate
smectite clay with a liquid to form a mixture, said mixture
containing clay in a range from 50% to 75% by weight and water in
a range 10% to 30%, kneading said mixture in a high speed, high
shear mixer to form a substantially homogeneous deformable mass,
forming said mass by extrusion under vacuum into a waterproofing
sheet, and laminating said sheet with a flexible, porous, carrier
sheet to form a laminate structure free of loose particulate
material.
24. A waterproofing material free of loose particulate
material, consisting essentially of a waterproofing sheet which
is formed by extrusion under vacuum from a substantially
homogeneous deformable mass consisting of a mixture of
particulate smectite clay and a liquid, in which respect the clay
is in a range from 50% to 75% by weight of the mixture and the
liquid comprises water in a range from 10% to 30% by weight of
the mixture.
25. A waterproofing material free of loose particulate
material, consisting essentially of a waterproofing sheet which
is formed by extrusion under vacuum from a substantially
homogeneous deformable mass consisting of a mixture of
particulate smectite clay and a liquid, in which respect the clay
is in a range from 50% to 75% by weight of the mixture and the
liquid comprises water and an organic material in a range from
10% to 30% by weight of the mixture.
