How to use Hessian for Masonry Frost Protection

When the cold weather starts it can have dramatic effects on masonry, the mortar in freshly laid project can freeze and expand in sub-zero temperature and the bond between motor and bricks can fail to set in temperatures below 2o C. This can cause serious damage which can result in rebuilds which are both costly in time and finances. There are cold weather precautions which can help eliminate issues caused by freezing weather. Bricks, blocks, sand and cement should be protected from ground frost, snow and ice by securing hessian rolls over the top of the building materials. Using frozen building materials during construction can create projects to become unstable and hazardous. Any new masonry constructions will require protection against frost where temperatures are expected to drop below 2°C. Protecting masonry with secured hessian can prevent damage. It is best to drape hessian roll over the full length on any wall and secure at both the top and bottom to prevent high winds removing the coverings. Hessian will provide a physical barrier against frost without creating condensation which can occur when using polypropylene tarpaulins. If temperatures are expected to fall well below freezing, anti-freeze agents may also be required. It is good practice to place thermometers in shaded areas to provide a guide to mortar setting temperature guidelines.
