Dedicated To Supporting Builder's Merchants

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:

 

Radon Gas

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.

 

Methane Gas

 

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.

 

Carbon Dioxide

A colourless gas which in sufficient concentrations can cause asphyxiation. Often associated with landfill areas it is formed by the oxidisation of carbon.

 

Hydrocarbons

 

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.

Radon Sump Unit

The Radon care and Cavity Gas Vent System is manufactured by a rotational moulding process from heavy duty polythene. The Sump is constructed with a solid roof and base and is provided with 40mm diameter holes in the walls.

 

Spigots for 100mm pipe connections are provided at each end of

the sump but are blanked off with knock outs to allow choice of direction for extract pipe. The cavity gas vent comes with a detachable polyethylene cap, which can be removed if an extraction system has

to be attached.
