Getting the best from Alphacrete®

During construction, Alphacrete® should be protected from the weather on-site including the covering of completed but uncapped work. These precautions will reduce the likelihood of efflorescence and subsequent lime blooming. 

After construction, completed walls should be covered using polythene to provide protection and to prevent uncured blockwork from being saturated. An air gap between the masonry and covers will enable newly built masonry walls to cure. The period this protection is needed will depend on the conditions but in cold wet weather it could be up to several days.

Care should be taken to prevent mortar smearing the surface of the Alphacrete® Masonry Block, as cleaning at a later stage could be difficult and can lead to expensive and time consuming remedial treatments. Prevention is better than cure.

All mortar joints should be well filled to help prevent weeping.

Cavities must be kept clean, as dirty cavities increase the risk of water reaching the inner leaf and can cause cold bridging.

Scaffolding boards should be turned back to avoid unsightly splashing of the work.

Masonry products should not be used if frozen and must be protected from frost and rain prior to construction and stacked on a level area on pallets.

Sand used for mortar production should be assessed for freezing and also be protected from the elements.

Building of architectural masonry should be avoided during severe wind, rain and where air temperatures fall below 2º.
