Understanding Wall Cracks

Wall cracks can signify various underlying problems, from minor cosmetic issues to more severe structural issues affecting your home’s foundation. Neglected cracks can lead to significant devaluation of your property if left unaddressed. Our team can assess the root cause of wall cracks and provide professional guidance on the best course of action to safeguard your property’s integrity.

Blue Board for Exterior Walls

Blue board, commonly used as an exterior wall cladding, is a solid 7mm sheet designed for acrylic rendering. This versatile material offers a beautifully rendered finish without the appearance of traditional masonry. Our team utilizes blue board extensively for external applications, including fencing and courtyard surroundings, due to its durability and aesthetic appeal. With options available in various sizes, blue board is an excellent choice for enhancing the visual appeal and functionality of your outdoor spaces.

Identifying Structural Concerns from Wall Cracks

Not all wall cracks are indicative of structural damage, but certain characteristics may raise concerns about the integrity of your building’s foundation:

  • Vertical Misalignment: If one side of the wall is notably higher than the other.
  • Width: Cracks wider than 5 mm (half a centimeter) may suggest structural weaknesses.
  • Location: Cracks originating from windows, doorways, or building corners are particularly worrisome.

Minor hairline cracks, typically resulting from seasonal soil movement, are often cosmetic and easily repairable. However, larger cracks may signal underlying issues that require attention.

Causes of Large Wall Cracks

Significant cracks can result from structural weakening due to water infiltration beneath the building’s foundations. Moisture-saturated or excessively dry soil can compromise the stability of the structure, leading to extensive cracking throughout the walls.

Effective Crack Repair Solutions

Addressing large cracks in walls requires comprehensive solutions to restore structural integrity. At Australian Rendering Company, we employ various techniques tailored to the specific needs of each project:

  • Crack Filling: Our team utilizes specialized plaster compounds and drywall joint compounds to effectively fill and repair cracks. We ensure meticulous attention to detail to achieve seamless results, whether it’s plastering over improper priming or stitching cracks in older homes.

Understanding Drummy Render and Concrete Spalling: Causes and Solutions

Drummy render, characterized by a hollow, drum-like sound when tapped, occurs when the cement or plaster render coating becomes loose and pulls away from the underlying substrate. This phenomenon can result from various factors, including heavy vibrations, water ingress, insufficient cement in the mix, or improper application of render. Additionally, activities such as plumbing and electrical work may contribute to the formation of a membrane that separates the render from the substrate.

Concrete spalling, on the other hand, refers to the deterioration of concrete surfaces, particularly at slab edges, due to exposure to moisture. This moisture can infiltrate from external sources such as rain or garden watering, leading to consistent dampness and subsequent issues like efflorescence, mould growth, and paint peeling on external walls.

 Australian Rendering Company, we specialize in diagnosing and addressing issues related to drummy render and concrete spalling. Our experienced team employs proven techniques and high-quality materials to repair and restore damaged render and concrete surfaces, ensuring long-lasting durability and aesthetic appeal for your property.
