Abstract
The present invention provides compositions used for filling joints in construction applications that remain hard yet pliable over time, even in gaps larger than 1.2 centimeters and methods of making the same.
Claims43
A joint filler composition comprising:
- a dry mixture containing at least one particulate filler;
- polyvinyl alcohol in an amount between about 1 and 10 percent by weight of said particulate filler;
- and
- a borate salt in an amount of at least about 10 percent by weight of said polyvinyl alcohol;
- wherein the balance of said composition is said particulate filler, and said composition is substantially free of water storage materials.
2 more elements
A joint filler composition comprising:
- a dry mixture containing at least one particulate filler selected from the group consisting of sand and stone dust;
- polyvinyl alcohol in an amount between about 3 and 7 percent by weight of said particulate filler;
- and
- a borate salt in an amount of at least about 10 percent by weight of said polyvinyl alcohol;
- wherein the balance of said composition is said particulate filler, and said composition is substantially free of water storage materials.
2 more elements
A method for producing a joint filler composition comprising:
- providing at least one particulate filler;
- adding polyvinyl alcohol in an amount between about 1 and 10 percent by weight of said particulate filler;
- and
- adding a borate salt in an amount of at least about 10 percent by weight of said polyvinyl alcohol;
- wherein the balance of said composition is said particulate filler, and said composition is a dry mixture that is substantially free of water storage materials.
2 more elements
A joint filler composition comprising:
- a dry mixture containing at least one particulate filler as-a polyvinyl alcohol in an amount between about 3 and 7 percent by weight of said particulate filler;
- and
- a borate salt in an amount of at least about 10 percent by weight of said polyvinyl alcohol;
- wherein the balance of said composition is said particulate filler, and said composition is substantially free of water storage materials and yields a shore A″ wet hardness of at least about 40.
1 more element
A method of filling a joint between paver blocks and/or stone, said method comprising:
- forming a composition that comprises at least about 90 wt.% of at least one particulate filler, polyvinyl alcohol in an amount between about 1 and 10 percent by weight of said particulate filler, and a borate salt in an amount of at least about 10 percent by weight of said polyvinyl alcohol, said composition being substantially free of water storage materials;
- filling said joint with said composition to a desired level;
- saturating said composition in said joint with water, and allowing said water-saturated composition in said joint to harden.
