The V-Lock sheet liner has 2 splayed studs, each one 15 mm in
length and joined by a cross bar in a V arrangement.
The double stud unit is formed during the extrusion process
and it is integral to the sheet itself. There are 400 such stud
units per square metre to ensure perfect embedment of the
sheet liner to concrete after casting.
The angle of splay ensures that the height of each V-LOCK
stud unit, from the top of the sheet in cross-section, does not
exceed 13 mm and that the V-Lock Liner can resist great pull-off
forces, both physical perpendicular pull-out type, and Hydraulic
type, exerted from behind the sheet itself.
V-lock lining outperform traditional coatings in aggressive acid and
caustic environments. V-lock lining is a suit of thermoplastic products,
which are welded or fused together to form a custom designed
lining for concrete structures.
This type of lining provides a chemical resistant, leak tight barrier to
contain environmentally hazardous materials or to protect concrete
structures from chemical attack.
The anchored concrete protective liners are locked into a cement
substrate to resist thermal expansion, contraction and groundwater
pressure. The high elongation of thermoplastics and the anchoring
system of V-lock concrete protective liners allows the liner to bridge
cracks in the substrate.
Some areas of use for V-lock lining are:
• Sewerage pipes
• Man holes
• Grease traps
• Concrete structures that need protection
