Vacuum Pressure treatment is a process in which Bamboo/ Timber is impregnated with water containing preservative. This helps in preventing from fungi/ other insects attack.

Bamboo is a natural material of organic origin. Without any protective treatment its durability is less than five years. Unlike varieties of timber like teak, bamboo structure is void of toxic deposits. The presence of starch makes it more attractive to microorganisms. Biological degradation can affect the usage, strength, utility and value of the bamboo/bamboo product leading to:

• decay and disintegration
• splits or cracks
• unsightly stains and blotches

Treatment is more economical in the long run. In order to improve the durability and performance, bamboo and bamboo products are treated with or without the use of chemicals.

Treatment is intended to:

• Extend durability and prolong useful life.
• Arrest and delay degradation.
• Preserve dimensional stability and retain strength
• Impart properties like fire resistance, lustre, etc
• Improve aesthetic qualities

Vacuum Process Treatment is a long term chemical treatment.

The Culm is first evacuated by creating a vacuum to partly remove air which may restrict entry of preservative solution due to air bubbles. The solution floods into the cylinder and forces into the Culm on release to normal pressure. Another cycle of vacuum is repeated to improve penetration and preservative loading.
