Back to basics
Once again we are informed that recently installed memorials have failed the memorial inspection test due to the cement joint between the memorial base and the foundation base failing, and the bereaved memorial owner ending up with a wobbly stone which can rotate on the ground anchor, and which is not attached.
British Standards BS 8415:2018. Basic engineering principle – Design and construction 5.1 General: Cement, mortar or adhesives shall not be the sole means used for the bonding of structural connections.
- Controlling a foreseeable risk. All structural connections are bolted or dowelled or a recognised memorial locking system. This will then eliminate memorial failures.
- The use of cement paste/grout on granite memorials is too rigid to use. Granite being exceptionally hard and almost an impermeable surface with an average density between 2.65 and 2.75 g/cm³. As the neat cement paste dries very hard this in turn does not allow it to flex, shift or expand with temperature changes which then causes it to become brittle and crack over time. Therefore cement paste has no structural strength or flexibility and cement on its own should never be used. This method of installation is totally inadequate.
