Strengthening walls

Problem

Reinforced concrete and masonry walls need to be strengthened against undue wind loads, deflactions, additional loads, shear cracks and extraordinary loads due to explosion or impact.

1. Deflections

Additional loads due to physical loading, wind or impact can result in flexural failure of walls. This is a result of insufficient lateral reinforcement in the wall or exceptional loads placed on the wall.

2. Damages

Wall structures are susceptible to sudden impact damage, causing localised failure in shear. Damage can arise from vehicle strikes, blast damage, impact from flying debris or accidental damage from other structural members.

3. Damages

Reinforced concrete walls are susceptible to damage caused by:

settlement of foundations
flexural bending cracks
shear cracks
thermal movement cracks
overloading
impact damage

Solution

Use externally-bonded reinforcement – sheet wrap

Install sheet wrap to the surface of the wall as containment reinforcement, flexural strengthening, impact strengthening and shear strengthening. The thickness of FRP wrap can be determined by design and the number of FRP sheet layers applied.

Masonry walls Sheet wrap – flexural strengthening

weber.tec force glass sheet

weber.tec force aramid sheet

Install layers of glass or aramid sheet to strengthen the wall in accordance with the design engineer’s specification.

Concrete or masonry walls Sheet wrap – impact strengthening

weber.tec force aramid sheet

Install multiple layers of aramid sheet to strengthen the wall against impact damage or blast damage from explosions. Aramid is excellent for impact strengthening to walls.

Concrete walls Sheet wrap – shear strengthening

weber.tec force carbon sheet C640

Install multiple layers of C640 carbon sheet ultra-high modulus to strengthen against shear cracking to concrete walls.
