T1/620

Height-adjustment ring

DN 625/850 mm

Polymer height-adjustment ring for construction of self-leveling and stationary type covers.

Height-adjustment ring is placed between support ring and adapter. It is installed when there necessary to increase the height of the chamber and reach surface level.

Advantages

Stable and long-lasting foundation for cover.

The smaller weight of the polymer elements ensures easy and quick construction process.

Can be installed in any weather conditions, D400 class durability immediately after construction.

High resistance against environmental influences.

Construction
- Chamber cover finial elements made from polymer are suitable for:
  - all the EVOPIPES chambers;
  - reconstruction of chamber covers of reinforced concrete chambers.
When assembling polymer chamber cover elements, one above the other, use silicone mastic, Ø 3-5 mm in two strips, on the surface of the polymer element!

During the assembly process the following remarks must be taken into account:
- Do not assemble the polymer surface finial elements on an unprepared ground, uneven, unlevelled, and unrepaired surface supporting the adjustment elements and in case of relief elements - on an uncompacted ground or substructure;
- Do not use cement-based mortar between polymer elements in the finial structure and between polymer and cast-iron elements of chamber finial;
- Do not make high adjustment based only on compensation rings with small dimensions (e.g. 21 cm adjustment made using 10 pcs of 15 mm rings and 2 pcs of 3 cm rings), as the possibility of height problem occurring during the operation increases the finial costs without any justification;
- Make sure that that frame of chamber cover is perfectly placed on the polymer elements.
