Outrigger Kitchen Floor tiles badly cracked

Hello, Two mains reasons I would say is movement in the substrate over time has caused it to crack which is transferred to the tile, a decoupling membrane matting would prevent this from happening in the future. Secondly I would say rising damp, if there was moisture coming through I would put down a liquid damp proof membrane over the old substrate.

If the floor tiles in the outrigger kitchen of the 1900s house are badly damaged, there could be various reasons for the issue, and rising damp is just one possibility. It's important to consider multiple factors that could contribute to damaged floor tiles: Damp Issues: While rising damp could be a concern, other types of dampness, such as penetrating damp from leaks or condensation issues, could also cause damage to floor tiles. Investigate for signs of water ingress, leaks, or condensation in the area. Subfloor Structure: If the subfloor is solid concrete with no damp-proof membrane, it could be more susceptible to moisture-related issues. Lack of a membrane can lead to moisture rising through the concrete, causing problems with flooring materials. Subfloor Ventilation: In older properties, inadequate subfloor ventilation can contribute to moisture-related problems. Ensure that there is proper ventilation to prevent excessive moisture buildup in the subfloor. Previous Water Damage: Consider whether there has been any previous water damage or flooding in the area that could have affected the subfloor and contributed to the damage to the floor tiles. Age and Wear: The property being from the 1900s means that wear and tear over the years could also be a factor. The subfloor and the tiles themselves may have deteriorated over time. To address the issue, consider the following steps: Professional Inspection: Hire a building surveyor or a qualified professional to inspect the area and identify the cause of the damage. They can assess the condition of the subfloor, look for signs of damp, and provide recommendations for remediation. Damp Proofing: If rising damp is suspected, installing a damp-proof membrane or other appropriate damp-proofing measures may be recommended. This could involve work on the subfloor or the installation of damp-proof courses. Subfloor Repairs: If the subfloor structure is compromised, repairs or replacement may be necessary. This could involve addressing any issues with the concrete and ensuring proper ventilation. Flooring Replacement: Depending on the extent of the damage, you may need to replace the damaged floor tiles. Choose appropriate flooring materials that are suitable for the specific conditions of the outrigger kitchen. It's crucial to address the issue before completing the sale, and consulting with professionals will help you determine the most effective and lasting solutions for the damaged floor tiles and any underlying problems.

over time there is expansion and retraction. re do tiles making sure to apply a membrane to suit concrete floors and movement.

• Moisture Assessment: Use a moisture meter to check the concrete subfloor for hidden moisture, even if there are no visible signs of damp. This can help confirm or rule out rising damp as the cause. • Subfloor Solutions: If it’s a solid concrete slab without a damp proof membrane (DPM), consider either installing a new DPM beneath a new concrete slab or applying a chemical DPM treatment to the existing floor before retiling. • Consultation with Specialists: For an accurate diagnosis and to explore the best repair options, consult with a damp proofing specialist or structural engineer, especially due to the property’s age.
