Effective Solutions for Rising Damp in Sydney Homes
1. Damp Proof Course Installation
To effectively address rising damp, it is crucial to understand the importance of the damp proof course (DPC). The DPC is a vital component in preventing moisture from entering your home through the ground. It serves as a barrier against moisture, strategically positioned within the walls to block the upward movement of water, ensuring that your heritage or coastal home remains structurally sound and visually appealing.
There are various methods of installing a DPC, each designed to meet different needs and accommodate specific structural conditions:
a. Chemical Cream Injections
This innovative technique involves injecting a silicone-based cream into pre-drilled holes along the mortar lines.
