Maintenance and Protection of Rammed Earth Buildings
As summer arrives, owners of rammed earth buildings turn their attention to surface maintenance, especially after enduring a long, punishing winter and the added complexities of COVID. Rammed earth structures, while celebrated for their thermal mass and natural beauty, require thoughtful care to preserve their integrity and appearance across seasonal cycles.
Surface Protection for Exterior and Interior Walls
Tech-Dry offers a suite of products designed to enhance and protect both interior and exterior earth walls, reducing the burden of ongoing maintenance. In modern Australian construction, rammed earth walls often incorporate Plasticure, a water-repellent additive mixed directly into the earth during construction. This integral treatment improves durability, resists moisture ingress, and significantly reduces the occurrence of unsightly efflorescence.
However, for existing buildings without Plasticure, all is not lost. Tech-Dry’s Stabilised Earth Water Repellent provides a reliable post-construction solution. Applied to exterior surfaces, it penetrates the wall and forms a water-repellent barrier. This helps prevent moisture-related damage and staining. For interior walls, dust accumulation can be a persistent issue, especially in high-traffic areas or homes with children and pets. To address this, Tech-Dry recommends Earth Binder, a dust-sealing treatment. Earth Binder stabilises internal surfaces and reduces airborne particles, making cleaning easier and indoor air quality safer.
These innovations reflect Tech-Dry’s commitment to long-term performance, environmental safety, and ease of maintenance. Whether you’re restoring an older structure or maintaining a new build, Tech-Dry’s solutions support the enduring beauty and resilience of rammed earth architecture.
Concrete Treatments for Interior Slabs
In a recent technical breakthrough, Tech-Dry has also developed environmentally friendly concrete treatments for the densification and protection of interior concrete slabs often found in rammed earth buildings. These advanced formulations improve surface hardness and enhance resistance to staining, without compromising sustainability goals. These products are:
