profloor wt series

sku: wtz4100 · floor
best for: back-of-house service areas, heavy load bearing driveways, and interior or exterior areas expecting multi-directional or seismic movement with high water usage.

Introducing the WTZ4100

The PROFLOOR WT expansion joint cover is a watertight solution for areas of high water usage where multi-directional or seismic movement is required. The top cover plate remains flush with the finishing surface during thermal movement and temporarily displaces to slide over the finish during seismic movement. Not recommended for forklift or heavy concentrated wheel loads.

01 — movement

movement

the wtz4100 takes up thermal and structural movement (the movement for each size is in the profile specifications below) while the cover stays seated on both sides of the joint.

integral punctureless water barrier

the cross-section shows the punctureless epdm/tpv water barrier integrated beneath the centre-bar assembly, connecting to the adjacent waterproofing membrane to eliminate every water entry point.

seamless finished installation

the centre-bar cover plate sits flush with the finished floor, exposed in aluminum or stainless steel, carrying heavy pedestrian and medium vehicular traffic across any gap size.

Punctureless Water Barrier Integration

The integral punctureless water barrier runs below the cover with no fixings through it, keeping the joint watertight in areas of high water usage.

Extruded Aluminum Base Frame and Cap

Extruded aluminum base frames and base caps are fixed to each slab with M8 sleeve anchors at 450 mm centres and carry the cover plate and the water barrier.

Steel Turnbar Assembly

A steel turnbar assembly at 500 mm centres holds the cover plate. The plate stays flush during thermal movement and slides over the finish during seismic movement.

Aluminum or Stainless Steel Cover Plate

The cover plate is supplied in extruded aluminum or stainless steel for heavy pedestrian and medium vehicular traffic. It is not intended for forklifts or other heavy concentrated wheel loads.
