Masonry has high compressive strength and low tensile strength
The steel cord knitted tape for masonry reinforcement is intended to be used in horizontal masonry joints,with normal purpose motar and AAC blocks,clay blocks,clay bricks,dense aggregate concrete blocks,stone,etc.as walls or partitions for structural use.
benefits both structural and traditional masonry.
Any reinforcement is better than no reinforcement.
Inside Applications
Outside Applications
Stress concentrations around window openings can be absorbed by applying two layers of HardTape above and below the window.
Shrinkage or expansion of materials can lead to cracks in the masonry. HardTape allows for larger gaps between movement joints.
Point loads, are highly concentrated loads that cause tensile stress and cracks in the masonry. Using a concrete beam as support interferes with the homogeneous character of the masonry.
Depending on the volume of the load, three to five layers of steel cord tape can be used with HardTape steel cord reinforcement tape for masonry. This HardTape ensures the even distribution of the load. It is important to check that the contact stress between the point load and the masonry is smaller than or equal to the calculated value of the compressive strength of the masonry.
Partition walls on a floor plate will start to crack in where there is too much sagging. To prevent this, we can use HardTape to reinforce the wall.
HardTape can ensure stability of the masonry with and without a stack bond. For masonry with a stack bond, the bricks are placed directly above each other, meaning reinforcement is essential for wall stability. With masonry without overlaps, reinforcement is required to compensate for insufficient bending bonding.
HardTape can provide the perfect corner connection. Reinforced corner and T-connection can decrease crack,evenly distribute load,eliminate stress concentration.
HardTape reinforcement allows longer or thinner wall partitions that can withstand high wind loads. Retaining walls, Cellar walls, or silo walls are exposed to considerable stresses from lateral loading. HardTape reinforcement increases the loading capacity of the wall span between the columns.
Improve the stability of gables by reinforcing a joint every 300 mm height with HardTape. If the gables are more than 8 m high ,it is recommended to reinforce every 200 mm . Always take the recommendations for long walls into account.
Prevent cracks by reinforcing one or two joints above the facade support with HardTape.
Masonry on partly hardened soil or uneven terrain is susceptible to deformations and stresses. HardTape is recommended to reinforce the masonry.Reinforce the first 5 joints and foundation ,Reinforce masonry located higher up every 400 mm
Masonry beams with HardTape reinforcement absorb the bending moments over windows and doors. They can be used with soldier- or stretcher course.
Note:These beams are only suitable for non-bearing masonry, using normal masonry bonding. The mortar quality requires minimal compressive strength of M5 and a minimal bond strength of 0.20 N/mm².
HardTape is the perfect reinforcement material for claustra masonry,this can remarkblly increase the masonry stability ,tensile strength.
