Masonry buildings have a range of benefits over traditional building materials as expanded below. From our inception masonry blocks have been the foundation of our business. Over time our range of traditional grey masonry has expanded to include architectural finishes. The benefit of supplying out of one masonry manufacturing site leads to a consistency in both structural quality and aesthetic.

The build process is invariably smoother when wall sizes and controls are designed to specific lengths and details that work for blocks. There are many resources available to assist designers and architects, these include;

3. Engage a professional mason to lay the product

Block layers can make all the difference when building with masonry. Block layers have a trade association that provides them with support in training and ongoing learning this goes above the licenced building practitioners. Above the trade association block layers can become Master Masons. Contracting with a Master Mason ensures the individual has been assessed as having an appropriate level of skills and knowledge to complete work to an industry best practice standard. More information can be found at the following links

Sealing - ViBlock

4. Sealing product

Viblock recommends all masonry is sealed to improve the look and durability of the product. Sealing is especially important for coloured masonry to reduce the likelihood of efflorescence and maintain the desired aesthetic over time. Viblock recommends Sto weathertight sealing systems are used for any walls open to the elements. For internal walls there are many sealers in the market it is important you have a professional installer complete the sealing and they follow the manufactures recommendations.

Efflorescence is a naturally occurring phenomena associated with all Concrete products. The chemistry involved is complex, involving several factors over which neither the manufacturer, the contractor, nor the end user has total control.

At Viblock we are very much aware of efflorescence and the problems it can create. Our manufacturing processes have all but eliminated the occurrence of efflorescence in our products, however unfortunately, we have no control over the environment in which our Masonry & Pavers are used.

In order to reduce the chances of efflorescence occurring, it is important that purchases care for the products from delivery to sealing (refer Viblock Care of Masonry, Pavers sheets and the paving laying guide).

Three steps to reduce the chance of efflorescence occurring

  • Products must be stored correctly before laying.
  • Laying of Blocks and pavers should be completed by a licensed trade professional.
  • Sealing should also be carried out by a trade professional

Efflorescence should it occur in no way effects the structural integrity of our Masonry Blocks and Pavers.
