NatSol    Green Dragon Environmental Standard Association for Environment Conscious Building

The COMPUS TWIN Full Access

NatSol does not usually carry out installation of its products. Instead we supply instructions and are happy to discuss installation with contractors.

Installation typically requires a 4 tonne machine, or larger, to carry out excavation and to lower the vaults into the ground. Assembly of the vaults and building requires general building skills.

We can offer supervision of installation for an agreed fee should this be required. In most cases we hope to avoid supervision in order to minimise costs.

We are, of course, very concerned that installations are carried out to a high standard by a competent builder who is familiar with all relevant health and safety procedures for the work involved and who will read our installation instructions and risk assessment thoroughly before the installation day. In order to help achieve this we follow certain procedures:-

 1. In parts of the country where we know of an experienced contractor we will supply clients with contact details so that they can obtain a quote from this contractor if they wish to.  2. We ensure that full installation instructions are sent out in advance to contractors and we are available to discuss these with them in advance.  3. With reasonable notice we are usually available by phone on the day of installation to answer any questions that may arise.

Having said all this, it must be understood that the contract for the installation is between the client and the contractor.

Installation instructions to download:-

Below are links to files which you can download. The first one is a risk assessment. The others are drawings and written instructions with photos to assist your understanding of the installation process. However, if you have actually ordered a toilet from us you should use the instructions we send to you or your contractor rather than using these on-line instructions which may be updated less frequently.

The last download on the list is a checklist of photos to take during the installation process and to send us before paying your contractor and receiving your guarantee.
