Application steps

Discover the application steps, the products used for this solution and other alternative products.

1

Existing substrate

2

Regularization layer POLYDREN PP

Place the regularization layer against the substrate using mechanical fastenings.

3

Fixing disk MAPEPLAN DISK

Apply the fixing disks by nailing them through the underlying regularization layer.

4

Waterproofing membrane MAPEPLAN

Spread the primary waterproofing membrane on the whole cap and fasten it through thermal welding on the fixing elements.

5

Protective layer (confinement of injection) MAPEPLAN PROTECTION

Spread the protective membrane in areas subject to risk of wear and fasten to the underlying layer through thermal welding.

6

Backup injection system MAPEPLAN INJECTION VALVE + IDROSTOP MULTI + MAPEPLAN END BOX

Preparation of the structural joint waterproofing system by laying IDROSTOP MULTI injectable hoses in correspondence with the WATERSTOP profiles, with subsequent arrangement of the post-casting injection points through suitable preparation of the hose junction boxes (MAPEPLAN END BOX).
