T-mex fabricates both dedicate leachate extraction wellheads and combined gas and leachate extraction wellheads. Most are fabricated around either an equal tee or reduced branch tee.

The wellhead inlet is generally extended to provide a telescopic sliding fit within a flexible adaptor which is located on the well liner. The top of the tee assembly will normally be fitted with screw cap, bolt on flange plate or stub flange, backing ring and blank plate.

Incorporated into the blank plate can be a number of sampling, monitoring, testing and extraction facilities.

On gas extraction wellheads a valve will normally be fitted onto the branch of the fabrication.
