The COMPUS TWIN FULL ACCESS

NatSol does not usually carry out installation of its products. Instead we supply instructions and are keen 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:-

  1. We have a list of contractors who have carried out satisfactory installations. Prospective clients can obtain a quotes from these contractors if they wish to. However, the inclusion of a contractor on this list does not constitute a recommendation.It must be understood that the contract for the installation is between the client and the contractor.
  2. We try to ensure that installation instructions are sent out to contractors when the job is first being discussed and we are available to discuss these with them. A further set including SITE SPECIFIC VAULT INSTALLATION GUIDANCE is sent with the boxed components before the installation day.
  3. With reasonable notice we are usually available by phone on the day of installation to answer any questions that may arise.

Installation instructions to download:-

Below are links to files which you can download. The first one includes 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 downloads on the list are checklists of photos to take during the installation process to send us before paying your contractor and receiving your guarantee.
