Unveiling the Power of Chemical Injection DPC: A Breakthrough in Damp Proofing

In the realm of property maintenance and preservation, the battle against damp is a constant struggle for homeowners and building professionals alike. The Office of National Statistics (ONS) has recently released a groundbreaking statement that sheds light on the effectiveness of a solvent based chemical injection Damp Proof Course (DPC) in rectifying damp issues. According to the ONS, a staggering 90% of damp-ridden properties can be successfully treated with chemical injection DPC alone, eliminating the need for additional and often costly treatments, including tanking and plastering.

The Triumph of Solvent Chemical Injection DPC:

Damp-related problems in buildings have been a persistent headache for property owners. Moisture infiltration not only compromises the structural integrity of a building but can also lead to a host of health issues and damage to personal belongings. The ONS statement comes as a ray of hope, emphasising the effectiveness of chemical injection DPC as a robust solution to combat damp.

Chemical injection DPC involves the introduction of a chemical damp suppressant into the walls of a property, creating a barrier that prevents moisture from rising and causing damage. This method has proven to be highly effective in addressing a wide range of damp issues, from rising damp to condensation-related problems. In recent years, the use of polymer or siloxane based DPC became popular, even though it’s now been proven to be 30% less effective than a solvent based DPC fluid.
Rochester Building and Damp only use solvent based products as they are proven to be highly effective, with results potentially lasting a lifetime.

Accuracy in Surveys: The Independent Advantage

The ONS statement also highlights a crucial aspect of the damp proofing industry – the accuracy of surveys conducted by independent timber and damp firms. According to the ONS, it’s smaller, specialised firms that consistently outperform nationwide damp proofing companies in survey accuracy.
Rochester Building and Damp has been independent since 1991.

Independent timber and damp firms are often locally based and possess a deep understanding of regional building conditions, climate and construction practices. This localised knowledge allows them to conduct more precise and targeted surveys, identifying damp issues with a higher degree of accuracy.

Nationwide damp proofing companies on the other hand, may lack the intimate knowledge of specific regional nuances, leading to potential misdiagnoses and ineffective treatment recommendations. The ONS encourages property owners to consider the services of independent timber and damp firms for more accurate and tailored solutions to their damp problems.
