## Abstract

Features for formliners to form a decorative pattern in a curable material and methods of using the same are disclosed. An improved formliner is disclosed with substantially seamlessly connecting components that reduces the need for using adhesives for interconnecting a plurality of formliners in a pattern. Further, the formliner is configured to reduce and/or substantially eliminate visible seams in order to create a more natural appearance in a finished product of the curable material.

## Claims

### Claim 1

A formliner for use with curable material, the formliner comprising:
a plurality of cells each configured to face the curable material;
a rib system comprising a plurality of ribs extending along at least two cells of the plurality of cells, the plurality of ribs forming at least parts of boundaries of the at least two cells; and
a channel extending along a cell of the at least two cells, the channel positioned between the cell of the at least two cells and a rib of the plurality of ribs, the channel extending through an other rib of the plurality of ribs between the at least two cells of the plurality of cells, the rib extending straightly at a portion of the rib forming the channel.

### Claim 2 (depends on 1)

The formliner of claim 1, wherein the channel extends into the cell to form an edge between the cell and the channel.

### Claim 3 (depends on 2)

The formliner of claim 2, wherein the edge is spaced from the portion of the rib forming the channel along an extent of the cell.

### Claim 4 (depends on 2)

The formliner of claim 2, wherein the edge is formed from the channel connecting to the cell at substantially 90 degrees.

### Claim 5 (depends on 1)

The formliner of claim 1, wherein the channel extends from the cell toward a surface configured to support the formliner.

### Claim 6 (depends on 1)

The formliner of claim 1, wherein the channel has a width generally corresponding to a thickness of the formliner.

### Claim 7 (depends on 1)

The formliner of claim 1, wherein at least some of the plurality of ribs are substantially polygonal shaped.

### Claim 8 (depends on 1)

The formliner of claim 1, wherein the formliner comprises a first end and a second end, the first end being formed to include a first finger joint pattern and the second end being formed to include a second finger joint pattern that is complementary to the first finger joint pattern, wherein the first end is configured to be overlaid with the second end to connect two or more formliners.

### Claim 9 (depends on 1)

The formliner of claim 1, wherein at least some of the plurality of cells have different sizes.

### Claim 10 (depends on 1)

The formliner of claim 1, wherein the plurality of cells comprise opposing ends, the plurality of cells being arranged in a plurality of rows with each layer having at least two cells disposed end-to-end.

### Claim 11 (depends on 10)

The formliner of claim 10, wherein cells of a first row of the plurality of rows are offset from cells of a second row of the plurality of rows.

### Claim 12

A formliner for use with curable material, the formliner comprising:
a plurality of cells each configured to face the curable material;
a plurality of ribs extending along at least two cells of the plurality of cells, the plurality of ribs forming at least parts of boundaries of the at least two cells; and
a groove connecting at least a part of a cell of the at least two cells to a rib of the plurality of ribs, the groove extending along at least portions of boundaries of the at least two cells, the groove extending into the cell to form an edge between the cell and the groove, the groove extending through an other rib of the plurality of ribs between the at least two cells of the plurality of cells.

### Claim 13 (depends on 12)

The formliner of claim 12, wherein the rib extends straightly at a portion of the rib forming the groove.

### Claim 14 (depends on 13)

The formliner of claim 13, wherein the edge is spaced from the portion of the rib forming the groove along an extent of the cell.

### Claim 15 (depends on 12)

The formliner of claim 12, wherein the edge is formed from the groove connecting to the cell at substantially 90 degrees.

### Claim 16 (depends on 12)

The formliner of claim 12, wherein the groove extends from the cell toward a surface configured to support the formliner.

### Claim 17 (depends on 12)

The formliner of claim 12, wherein the groove has a width generally corresponding to a thickness of the formliner.

### Claim 18 (depends on 12)

The formliner of claim 12, wherein the other rib of the plurality of ribs comprises a first wall extending upwardly from an other cell of the at least two cells, a second wall extending from the first wall substantially in parallel with an extent of the other cell of the at least two cells, and a third wall extending downwardly from the second wall toward the extent of the other cell of the at least two cells, and wherein the rib of the plurality of ribs comprises a fourth wall extending upwardly from the groove, a fifth wall extending from the fourth wall substantially in parallel with an extent of the cell of the at least two cells, and a sixth wall extending downwardly from the fifth wall toward the extent of the cell of the at least two cells.

### Claim 19

A method for assembling formliners, the method comprising:
connecting a first formliner with a second formliner by overlaying at least a portion of an overlapping section of a rib of the second formliner onto at least a portion of an overlapped section of a rib of the first formliner, the overlapping section of the rib of the second formliner configured to face curable material; and
positioning at least a portion of a first rib edge of the overlapping section of the rib of the second formliner into a groove of the first formliner, the groove of the first formliner extending between the rib of the first formliner and a cell of the first formliner, the groove extending into the cell of the first formliner to form an edge between the groove and the cell of the first formliner, the cell of the first formliner configured to face curable material.

### Claim 20 (depends on 19)

The method of claim 19, wherein the groove of the first formliner extends through an other rib between the cell of the first formliner and an other cell of the first formliner, and further comprising positioning the at least a portion of the first rib edge of the overlapping section of the rib of the second formliner into the extent of the groove through the other rib connecting the cell and the other cell of the first formliner.

### Claim 21 (depends on 19)

The method of claim 19, further comprising placing curable material against exterior surfaces of the first and second formliners to create a pattern in the curable material.
