When the Lans Lock method is applied on an ALC base, the anchorage strength of anchor pins has to be checked.

Environmentally-responsive high durability combined waterproofing method (method with a long-term guarantee of 30 years)
Advantages of the VD method

Combined waterproofing
Improved asphalt sheet
Rapid-hardening and high-durability type urethane

Combined waterproofing using “Plamax,” a rapid hardening-type urethane, and “Hybrid sheet,” an improved asphalt sheet. This is an advanced waterproofing method in which the degree of impact on the global environment is taken into account.
Typical rooftop
Characteristics
Combined waterproofing method with a 30-year guarantee
The system unique to the VD method is adopted to meet the requirements for the long-term use of buildings. On condition that the top coating is repainted every 10 years [charged separately], we guarantee the quality of the waterproofing layer for 30 years. (The top coating has to be repainted every 15 years [charged separately] in the VD-HG.)
Outstanding durability under severe conditions
The high durability of “Plamax” adds to buildings’ lifespan. Plamax shows high durability even under severe conditions.
Reusable material containers
To enable the major materials used in this method to be easily taken out of their containers, a polyethylene bag is placed inside the containers. This makes reuse of containers possible.
