Radon Barriers & Radon Membranes

A Radon Barrier is a flexible sheet of material designed to prevent Radon Gas from entering a building (either a Home or a Workplace).
Current regulations stipulate that a Radon Barrier must be fitted into new-build buildings in 'at-risk' areas.
The Radon Barrier is fitted after the foundations of the building have been laid, and is covered with a concrete slab.
It is essential that the Radon Barrier is fitted correctly and all overlaps are thoroughly sealed. Anything that protrudes through the Radon Barrier (usually Utilities like Water pipes, drains, electric cables and gas) must have a seal around it to ensure a well fitted Radon Barrier and prevent Radon Gas ingress into the building.
The Barrier comes in rolls and where these rolls overlap, the overlap must be sealed with either an adhesive, or a Thermal seal (where the two layers are melted together to form a join). This ensures the continuity of the Barrier.Using Radon Barrier products can give the following advantages:
Radon Barrier Benefits
- A radon resisting membrane will also act as a damp proof membrane to protect the building against the ingress of moisture from the ground
- Easy installation
- Meets with building regulations
- Can be tested prior to the pouring of a concrete slab to ensure full compliance and protection
Due to their nature, Radon Barriers are generally only fitted to new buildings.
In the case of an old building that needs Radon Mitigation, a Radon Sump and extractor fan can be installed to remove the build up of Radon Gas.
Waterproofing
The Waterproofing requirements of any Building are dependent on the purpose for which the Building was constructed.
A domestic basement or cellar needs a significantly different different approach than that required for an underground car-park where damp areas are less of an issue.
Our significant expertise in this area lets us carry out the work that you need for your particular building whilst maintaining all regulatory requirements.
Our experience includes (but is not limited to):
- Cementitious Tanking - a polymer modified cement based protective and waterproof slurry coating
- Cavity Drain Membranes - high density studded polyethylene sheets (HDPE) and polypropylene (PP) which are impervious to water and vapour proof
- Bituthene Membranes - a pre-formed Membrane of a high performance, cross laminated, HDPE carrier film with a unique, tacky, self-adhesive rubberized asphalt compound
Radon Sumps & Fans

Radon Sumps (with or without Fans) can be used instead of a Radon Membrane - each Sump can cover a floor area of up to 200m2.
The Sumps and necessary pipework are installed in the Hardcore layer prior to the pouring of the slab flooring.
Sumps can also be installed in older buildings that fall short of the Radon Gas Requirements for certification as installing a Radon Barrier into a pre-built building is almost impossible.
An Extractor Fan can also be added during installation where necessary, although this is not generally required.
The Sumps have up to 4 input/output fittings to which 110mm pipes can be attached for Radon Extraction. The input/outputs can also be used to interlink multiple Sumps so that they all feed to the same extraction point, thus reducing the amount of core drilling and fittings necessary for the build.
Domestic Installations
In addition to Industrial Installations, we also do a significant amount of work on Domestic Builds.
This includes new-build houses, extensions and remedial works on older buildings.
Our domestic work covers all of the areas included our industrial works, just on a smaller scale.
- Radon Barrier Membranes
- Radon Sumps
- Waterproofing
- Core Drilling
Our previous Domestic work ranges from a single extension to new builds of 300+ homes, so we have you covered whatever your needs.
Core Drilling
Core Drilling is a necessary part of most Construction works.
It's general use is drilling holes through walls or slabs to facilitate the passage of services such as water, electricity, and waste, or for the extraction of Radon Gas when a Sump is used.
It is an accurate, quick, easy and relatively clean way to drill holes in concrete and brick-work.
We specialise in core drilling for both Domestic and Industrial needs.
We use only the highest quality equipment to ensure that the work is carried out as efficiently as possible.
