Expert weatherproofing services for modular building penetrations

As part of our comprehensive design and build service, we can manufacture and install bespoke load-bearing curbs, as well as vertical and roof penetrations on all modular building types from any manufacturer, including Portakabin. Our unique fibre-reinforced weathering system ensures a reliable and professional finish with long-term performance.

We have experience working on modular buildings for a wide range of applications; from schools and universities to hospitals, offices and factories. Our services include:

  • Application of our specialist GRP weatherproofing
  • Design, build and installation of GRP upstands
  • Installation of cable trays and plant deck
  • Roof repairs
  • Roof maintenance

Because our weatherproofing method does not require additional penetrations for fixings, the result is a more aesthetically pleasing roof finish. This also helps to avoid thermal bridging and maintain U-values for thermal efficiency.

Creating wall or roof penetrations in modular buildings is straightforward however, ensuring structural integrity and a weatherproof seal is more complicated. Getting it right is critical, and the team at Jones Weatherproofing has the skills and expertise to provide reliable, high-quality building penetrations that prevent rainwater ingress and wind damage.

Adapting modular buildings with weatherproof penetrations

Because they are cost-effective, quick to install and reliable, modular buildings are a popular option to increase space within existing premises. They are widely used in sectors ranging from education and healthcare to construction and manufacturing. Depending on the application, modular buildings can be adapted in a variety of ways to meet project requirements. They are often customised with features such as:

Service Risers

Wherever pipes or ducting enter or exit a building, the penetration can be prone to water ingress and other problems. This is particularly problematic for service risers that extend upwards through a roof, which is a typical issue for plant decks.

Commercial Roof Repairs

When a commercial roof is in need of repair, you’ll want to get it fixed quickly and to a high standard. Weatherproofing is key, and many leaky roofs can be attributed to poor weathering around the building penetrations.

Commercial rooflight and window installations are excellent ways of providing natural lighting and ventilation, but unless they’re installed correctly, they can also result in problems such as leaks, damp and draughts.

Modular building penetrations – onsite or offsite

For modular buildings that are already in place, our team can come to you to install building penetrations and weatherproofing. With more than 45 years of experience, we know how to work quickly and efficiently to avoid unnecessary disruption.

If the modular building has not yet been delivered, we can attend the manufacturing site to have the building penetrations installed and weatherproofed. We are the only building penetration specialist to offer this service offsite, significantly reducing construction time and disruption on site.
