The Rhinoplast range of Gas Barrier Systems has been designed to provide a complete solution to the problems associated with construction on land associated with a range of hazardous gasses, when installed in accordance with the relevant codes of practice.
Rhinoplast Gas Barrier Systems
We offer a ''pre pour'' inspection service to ensure correct installations and detailing.
Assessing the risk:
It is requirement of National Planning Policy Framework and Building Regulations Approved Document C, that where the proposed structure is at risk from gas contaminated land, the developer must carry out a risk assessment for submission to the local planning authority.
The types of ground gasses commonly encountered are:
A colourless, odourless naturally occurring radioactive gas. This gas is prevalent in granite areas but can occur almost anywhere. Granite is naturally rich in uranium. It is widely held that exposure to Radon Gas is a major cause of lung cancer.
A colourless gas formed by the decomposition of organic material. The gas
is flammable and potentially explosive even in relatively low concentrations. This gas is common on or near landfill sites, mining areas etc. This gas becomes explosive at concentrations of 5% subject to an ignition source.
A colourless gas which in sufficient concentrations can cause asphyxiation. Often associated with landfill areas it is formed by the oxidisation of carbon.
A range of hazardous substances often associated with the petrochemical industry. Typically found in disused petrol stations and industrial sites.
These barriers are designed to protect structures and inhabitants from the effects of these gasses. They will also act as damp-proof membranes where applicable and are intended to last the life time of the building. All of our membranes can be welded.
With the increase in awareness of such gasses, along with more and more stringent requirements, it is becoming more and more important for contractors to use '' fit for purpose materials'' in the secure knowledge that they will perform satisfactorily.
As pressure mounts on the construction industry to build on " Brown Field Sites " the demand for these products is increasing daily.
The primary method of protection to the structure is by way of a complete ''footprint'' membrane system combines with underfloor passive venting. The key to a successful outcome is installation. The best membranes poorly installed are likely to fail.
The Rhinoplast range includes pre-formed details and tapes to facilitate this. Where necessary we will provide on-site advice and training to ensure a successful outcome.

Rhinoplast Evolution Hydrocarbon Gas Barrier.
Rhinoplast Evolution Hydrocarbon Gas Barrier
Rhinoplast Evolution is a high specification co-extruded multi-layer barrier specifically developed for use on construction sites contaminated by Volatile Organic Compounds, Hydrocarbons and other ground gasses such as Methane, Radon and C02.
The product is 14 layers and contains 2 layers of gas barrier polymer (EVOH) to offer exceptional performance and prevent the ingress of dangerous gasses into buildings. It is manufactured using the latest co-extrusion technology and cannot delaminate. The product will also act as a damp-proof membrane.
The membrane is manufactured using high performance engineering polymers to give exceptional strength and does not require reinforcement. It can be installed by the use of sealing tapes or can easily be welded.
Standard roll size: 1.65m x 61m
Rhinoplast Hydrocarbon Barrier
An HDPE membrane designed to withstand the effects of fluid hydrocarbons. Tremendously strong and puncture resistant.
Available in: 1mm and 1.5mm thickness
Rhinoplast LT Jointstrip
