Delivering Damp Proofing for Commercial Properties

To ensure at the right solutions are deployed for the specific requirements, each situation is audited by one of our qualified, certified CSRT/CSTDB.CSSW surveyors to clearly identify the scope of work.

A detailed report summarises the source of the damp, recommend treatments and a quote for the necessary repairs. Photos support the findings and we welcome a follow-up conversation to answer any questions.

Typical treatments where remedial works are required:

Delivering Timber Treatment for Commercial Properties

The B2B sector is a primary driver of the timber treatment sector, accounting for the vast majority of volume and high-performance chemical applications. Many businesses require industrial-grade treatments to meet legal building codes, safety standards and long-term infrastructure goals.

Timber treatment is about risk management and ROI:

  • Compliance & Building Regs: Structural timber used in commercial buildings must meet specific “Use Classes” (e.g., UC3 for cladding, UC4 for ground contact).
  • Liability: If a commercial deck or a utility pole fails due to rot, the business faces significant legal and financial liability.
  • Longevity (15–60 Years): Businesses look for service life specifications. Industrial pressure treatment can extend the life of a timber post from 5 years to 30+ years, drastically reducing replacement costs.

In cases where damp has affected structural timbers, treatments we suggest include:

Delivering Basement Tanking for Commercial Properties

Basement tanking in commercial buildings is a waterproofing method used to prevent water from penetrating below-ground structures like basements, cellars and underground parking areas. It’s especially important in areas with high groundwater levels or poor drainage.

We create a watertight barrier on walls and floors to stop moisture ingress. The type of system used depends on your risk level and building use and we work with our clients to understand the best solution for their needs.

Additionally, other services we offer include:

All treatments are delivered in compliance with PCA standards and covered by our 20-year guarantee. Prokil supports health and safety needs under CHAS and other rules for commercial projects when needed.
