The Combi series is made from high quality HDPE (high density polyethylene). Additives are added, which secure lifespan and optimal strength, without deformation.

The Combi series is a classic when it comes to elevation/blocking-up joist floors and terraces made from wood.

The Combi Base along with one of the four Combi tops form the basis of a Combi elevation/blocking-up (32 – 99 mm). All four combinations of base + top can be heightened with 1-5 Combi extensions of each 35 mm. These opportunities grant an elevation/blocking-up span of 32-274 mm.

There are two types of soles in the Combi series; One sole to protect a vulnerable foundation like roofing felt and one that grants an effective and documented step impact soundproofing.
