Addressing Brickwork Defects - Spalling & Moisture Trapping
Spalling brickwork, characterised by the cracking or breaking of bricks or building materials beneath the surface, is often a result of water penetration. This issue manifests as flaking, cracking, peeling, crumbling, or chipping stones or bricks. The cycle of rainwater infiltrating bricks, freezing, expanding within gaps or holes, and subsequently melting can cause this subsurface damage.
While spalling might initially seem like a mere cosmetic concern, it can escalate into significant structural damage, incurring hefty repair costs if left unattended. During colder months, the freezing temperatures can exacerbate hairline cracks and holes, especially when coupled with damaged gutters and improperly fitted window and door frames.
For properties exhibiting painted spalling brickwork, it's recommended to strip away the masonry paint entirely and opt for lime wash or mineral paint as a preventive measure against future issues.
It's crucial to note that while cement-based mortar and renders are suitable for newer constructions, they can be detrimental to older buildings that were originally built with lime mortar. Cement pointing in such older structures can trap moisture at the brick's edge, leading to breakage during freeze-thaw cycles. Similarly, cement render can hold onto moisture, inducing dampness and hastening erosion. Our Surveyors typically advocate for lime-based mortars, renders, and plasters for older properties, as they facilitate the escape of trapped moisture, ensuring better breathability.
