Abstract

The present disclosure is directed to systems and methods for structural reinforcement against shear forces. The reinforcement systems comprise a fluid- applied coating applied to a surface of a substrate of a structure and a mesh applied to the fluid applied coating, adhered to the substrate by the fluid applied coating, and exhibiting an area density of at least about 200 g/m2. The mesh can be disposed between the first and a second fluid-applied coating and can be oriented in various configurations to increase the resistance of the substrate to shear forces.

Claims

AMENDED CLAIMS received by the International Bureau on 29 December 2015 (29.12.2015)

2. The system of claim 1, wherein the reinforcement layer further comprising a second mesh disposed on the second fluid-applied coating.
3. The system of claim 2, wherein the reinforcement layer further comprises a third fluid-applied coating disposed on the second mesh and at least a portion of the second fluid-applied coating, wherein the third fluid-applied coating comprises the elastomeric polymer.
4. The system of claim 1, wherein the mesh comprises a coated glass fiber.
5. The system of claim 1, wherein the elastomeric polymer comprises an acrylic polymer.
6. The system of claim 2, wherein at least one of the mesh and the second mesh comprises a woven glass fiber. 27
7. The system of claim 6, wherein the mesh comprises a first woven glass fiber comprising a first plurality of warp strands and a first plurality of weft strands, and wherein the second mesh comprises a second woven glass fiber comprising a second plurality of warp strands and a second plurality of weft strands, and wherein the first plurality of warp strands are aligned biased to the second plurality of warp strands within the reinforcement layer.
8. The system of claim 1, wherein the substrate comprises a joint, wherein the joint has a joint length and a joint width and wherein the first fluid-applied coating covers at least a portion of the joint.
9. The system of claim 8, wherein the first fluid-applied coating is disposed in at least a portion of the joint.
