Presentation on Brick/Block Mesh Reinforcement
By: Christopher Nganga Gathini
Collaboration Engineering Solutions and Products (K) Limited
Synopsis:
Increasing cases of masonry defects in
construction
Lack of consistency in the quality of
building materials
Use of inappropriate building materials for
masonry works
Need to specify economical and durable
materials for masonry construction
Need to sensitize the market on
availability of alternative quality products

Brick Mesh Reinforcement:
Features:
Better bond between masonry units
Economical to transport
Easy and economical to store
Reduction in implementation time (high
performance specification)
No skilled labor required
Quality assured by implementation
factory
Reduction in Wastes and fallings
Engineered for performance and
durability
Cost savings of between kshs. 6.5 to 16.5
per meter length

Truss/ladder reinforcement:
Features:
Reinforces a variety of masonry walls
Greatly reduces cracking that can arise
from thermal stresses
Enhances resistance to water penetration,
as cracks are controlled
Increases lateral flexural strength
Bonds exterior and interior masonry
wythes together in composite walls
Bonds masonry at intersecting walls and
corners
Increases elasticity
Increases performance of masonry walls
under various stresses
