Abstract
Abstract The erosion control blanket of blocks comprises a plurality of concrete blocks having a preselected configuration and being joined to adjacent blocks of the configuration by at least one of a plurality of embodiments of a reinforcing lattice structure. Individual blankets may be joined together to create a desired configuration for a substrate covering. Provision of the blocks in a blanket configuration provides a process of laying the blocks with attached lattice which is time and labor saving.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
77 words
A blanket of concrete blocks having a preselected configuration and having blocks thereof adhered to and held together by at least a first reinforcing lattice extending across a bottom surface of the blanket and to edges of the blanket, the blocks being positioned adjacent to one another with gaps therebetween, and adhering to the at least first reinforcing lattice by having wings of lattice underlying each block flexed into the concrete of each block during production thereof.
Claim 2
Dependent Claim
77 words
A blanket of concrete blocks having a preselected configuration and having blocks thereof adhered to and held together by at least a first reinforcing lattice extending across a bottom surface of the blanket and to edges of the blanket, the blocks being positioned adjacent to one another with gaps therebetween, and adhering to the at least first reinforcing lattice by having wings of lattice underlying each block flexed into the concrete of each block during production thereof.
Claim 3
Dependent Claim
13 words
The blanket of claim 1 wherein the reinforcing lattice is a geotechnical underlayment.
Claim 4
Dependent Claim
14 words
The blanket of claim 1 wherein the reinforcing lattice is a flexible matrix material.
Claim 5
Dependent Claim
21 words
The blanket of claim 1 wherein the reinforcing lattice is a grid of tubular structures which are layered according to direction.
Claim 6
Dependent Claim
19 words
The blanket of claim 1 wherein the reinforcing lattice is geotechnical material underlayment in combination with flex matrix material.
Claim 7
Dependent Claim
18 words
The blanket of claim 1 wherein the reinforcing lattice is geotechnical material underlayment in combination with tubular grid.
Claim 8
Dependent Claim
13 words
The blanket of claim 1 wherein said blocks are contiguous to one another.
Claim 9
Dependent Claim
13 words
The blanket of claim 1 wherein said blocks are spaced from one another.
Claim 10
Dependent Claim
10 words
The blanket of claim 1 wherein said blocks are hexagonal.
Claim 11
Dependent Claim
10 words
The blanket of claim 1 wherein said blocks are rectangular.
Claim 12
Dependent Claim
10 words
The blanket of claim 1 wherein said blocks are octagonal.
Claim 13
Dependent Claim
86 words
An erosion control system created from a plurality of blankets of concrete blocks having a preselected configuration and having the blocks thereof adhered to and held together by at least one reinforcing lattice extending across a bottom surface of the blocks and at least to edges of the blanket, such blankets being configured to have end edges of lattice which are matable with end edges of lattice of any adjacent blanket to produce any desired configuration for the system without interruption to a preselected block pattern.
Claim 14
Dependent Claim
86 words
An erosion control system created from a plurality of blankets of concrete blocks having a preselected configuration and having the blocks thereof adhered to and held together by at least one reinforcing lattice extending across a bottom surface of the blocks and at least to edges of the blanket, such blankets being configured to have end edges of lattice which are matable with end edges of lattice of any adjacent blanket to produce any desired configuration for the system without interruption to a preselected block pattern.
