INTRODUCTION
vSlab is a precast prefabricated insulation concrete slab. It is used on reinforced concrete flat roofs as a thermal insulation and sound isolation layer. It also plays the role as a protection screed layer for waterproofing membrane of inverted-roof-system.

VSLAB PAVER
Aside from the vSlab (With Blue Foam), Vodapruf has also manufactured a “vSlab Paver”. It is a form of ferro cement slab that is used as an insulative slab for external application. It has a 4-leg frame underneath each paver, like a pedestal. A Paver has the strength to withstand weight and human traffic.
TECHNICAL ADVANTAGES
It has an immediate-open-to-traffic curing time with a high productivity rate of 125m2/man/day. It is a single layer installation as compared to some industrial method of a 3-layer method such as Cast-in-Situ Panels. Therefore, producing a consistent quality-finishing.
