Pressure grouting is one damp-proofing method.
Understanding Pressure Grouting
Pressure grouting is a technique used to prevent dampness in structures. It involves injecting a grout (a mixture of cement, water, and other additives) under pressure into cracks and voids within a structure's foundation or walls. This high-pressure injection forces the grout deep into the gaps, effectively sealing them and preventing moisture penetration. The pressure ensures complete filling of the cracks, preventing water ingress.
How Pressure Grouting Works
- Identification of cracks and voids: The process begins with careful inspection to locate areas where moisture is entering the building.
- Grout injection: Specialized equipment is used to inject grout under pressure into the identified areas.
- Grout setting: The grout hardens, creating a waterproof barrier that prevents further moisture penetration.
Advantages of Pressure Grouting
- Effective sealing: Pressure grouting effectively seals even the smallest cracks and voids.
- Long-lasting solution: The grout forms a durable, long-lasting barrier against moisture.
- Minimal disruption: The process is relatively non-destructive, minimizing disruption to the building.
