135mm Cellcore Cellvent HX Grade 7/10 combines the benefits of the Cellcore HX range with Ventform to alleviate the effects of ground heave whilst also providing an excellent gas venting medium.

Cellvent HX is available in a range of specifications and can be used in conjunction with gas membranes, vent outlets and venting accessories to form a complete gas protection system.

Cordek EPS Void Former Formwork Cellvent HX is designed for use under suitably reinforced ground floor slabs where subsidence is not expected.

Cellvent HX is supplied with an equivalent ventilation capacity to the Ventform 80 range which includes a 40mm void depth, If a greater venting capacity is required, please contact us.

The depth of the Cellvent HX panel will depend upon the amount of ground heave that has been predicted.

Grade 7/10 is calculated and calibrated for concrete thickness up to 220mm (has been tested to achieve the specified performance characteristics).

Cellvent HX is a highly-durable, BBA certified product which meets the NHBC’s Technical Standards.

One of great things about Cordek Cellvent HX is its very simple to work with and doesn't have much dust off when cut on site.

The cost of manufacturing Cellvent HX is considered linearly proportional to its grade which is based on maximum concrete depth.

Cellvent HX Grade 7/10 price is the lowest compared to the higher grades: 9/13, 13/18, 18/24 (price available upon request/quote).

Equivalent to 135mm Cordek Cellvent HX is 90mm Cordek Cellcore HX S Under Slab.

Grade 7/10 means that safe load is 7 kN/m2 and fail load is 10 kN/m2 (kilonewtons per m2).

Safe load is a maximum safe force that a Cellvent HX material offers without fear of breaking.

Fail load is not safe force and will cause permanent deformation of the product.

Shrinkage category of 135mm Cellvent HX is classified as low.

Cordek Cellvent HX Soil Plasticity index is 10-20.
