fast basement waterproofing

VANDEX CLADDING OF STONE/ BITUMINIOUS FELT.

Easy& Fast application (even when application (even when wet)wet)

No Protection needed (Cost saving).

Long Life Forms part of Structural concrete. Crack Bridge by crystallization

upto 0.3 mm . Sealmess and no fear of joint

failures due to age. Vandex Super is part and parcel of the structural concrete incase of structural alterations there are no cold joints formed due to age of applications.

Can be applied with ease from negative side of basement structure and can be applied post construction also.

Very Slow application and time consuming.

Protection needed (Extra cost) Extra cost of protection Does not form part of structure. Has very Limited crack bridging

capacity. Fear of Joint failure ever present

due to water pressure or age or poor workmanship

Does not form part of structural failure the system is not repairable from negetive side.

Can not be applied or used from negetive side or post construction.

Three elements of a successful

Vandex application

1. Surface preparation

How it shouldn’t be !!

• The laitance is still existing

Surface preparation

All concrete to be treated must be clean and have an ”open” capillary system. Remove laitance, dirt, grease, etc. by suitable means.

Concrete without any surface preparation

Concrete which received a surface preparation by high pressure water

jetting

• Aggregates are visible

Concrete which received a surface preparation by water-sandblasting

Water-sandblasting

• 180 bar water

• plus sand

Routing out visible cracks not subject to movements that exceed 0.3 mm

Application of Vandex products

Prewatering

Surfaces must be carefully prewatered prior to the Vandex application. The concrete surface must be damp but not wet.

Simple test by hand

Do not apply the products at temperatures below the values indicated on the product data sheet or on frozen substrates

Control of material consumption in relation to the surface => correct layer thickness

When problems arise, stop the application and investigate => damage limitation
