• Easy Application – As a moisture-cure one component type water-sealing. Standard caulking guns can be used as for conventional sealants.
• Physical Properties -After hardening, it has better physical properties than those of conventional putty type sealants.
• Water-swelling – Swelling up to 2 times (approximately) by Volume as a result of its water absorption ability.
• Good Adherence – It adheres to various materials such as concrete, metals, glass, etc.

• Water sealing of joints in cast-in-situ concrete
• Water sealing around steel posts/columns, king posts, that are cast into concrete
• Water sealing around pipes for pipe penetrations through concrete
• Box culverts & manholes joints
• Form tie holes and form ties
• Rough concrete surfaces of joints
• Hydrostatic head pressure resistance of up to 2 bar (20metres)

Note: The products design and performance, its intended use, installation and final confirmation and approval for use, must be provided by the project’s Design Engineer and Project Manager.

1. Break the moisture-proof aluminium foil on the top of the cartridge, and remove the metal coverseamer from the bottom.

Where shown on the drawings, the hydrophilic gun grade waterstop sealant shall be Leakmaster LV-Z as supplied by CJSA. The Hydrophilic gun grade waterstop sealant is to be polyurethane based and able the be adhered on to concrete, steel, ceramic and/or plastic surfaces. It must have a minimum expansion capability of two times by volume (200%) and be able to withstand a minimum of 2.0 bar (20 meters) of hydrostatic head pressure resistance and proof of this must be provided by an independent laboratory test report. The product must be installed in accordance to the supplier’s installation guidelines and the Design Engineer’s specification.

In confined spaces or in still air conditions, the use of a ventilation fan or suitable respirator should be used, and the advice and approval of the Site Safety Supervisor is essential.
