Riser rings, cones and covers

With many years of experience and co-operation with our customers, we have developed a complete series of riser rings to adjust the well-constructions. The risers are made from recycled plastic, and thus has a high strenght and a low weight. They kan be combined as required to reach the right hight of the construction. The cover can also be used as protection of the shaftpipe, while the construction is being done. The cover is installed inside the cone preventing material to fall down in the well when opened.

Our cones are also made of recycled plastic. The cones are available with or without rabbet. They are much lighter than concrete and therefore much easier to work with. 

Finally our covers and frames are all made of recycled plastic. We have both covers and frames with and without rabbet. The covers and the frames are designed to load class A. They are much lighter than concrete and therefore much easier to work with.
