DANODREN H25

About this product

DANODREN® H25 is a 7.5mm deep brown nodular membrane made of high density polyethylene (HDPE) for protection and vertical drainage.

Protection of the waterproofing of buried walls in buildings and civil works, such as cut-and-cover tunnels and subways.

Protection of above-ground screeds.

Renovation of basements and underground constructions affected by damp.

Combined with layers of filter materials it can provide adequate drainage.

In cases of renovation, an air gap is created between the damp affected wall and the new finish, allowing it to ventilate and dry.

Easy and quick to install.

Chemically unchanged when in contact with chemical agents present in the soil (sulphates, chlorides, etc).

Provides permanent drainage.

Protects the wall from damp and allows water to drain, limiting its hydrostatic pressure.

Protects the waterproofing sheet from possible piercing caused by fill earth.

Resistant to breakage, impact and does not deform.

Walls :

The surface of the substrate and singular points must be uniform, clean, dry and free of foreign bodies.

The substrate for DANODREN H can be a waterproofing film.

DANODREN H is laid with the nodules facing the substrate. The sheets should be overlapped by 12 cm horizontally and 20 cm vertically.

The upper part is anchored with the DANODREN metal profile and mechanically fixed (they may also use HILTI-type fasteners, model X-SW or similar). In this way, the drainage sheeting is protected against dumping, backfilling and subsequent compacting of the trench and water ingress. This fastening must be 10 cm above the waterproofing membrane.

The corners and corners are finished off by bending the sheet.

Lay the drainage pipe.

Screeds:

When there is no hydrostatic pressure or the screed is above the water table, DANODREN H is spread with the nodules against the ground. The sheets should be overlapped by 12 cm.

Damp areas:

In case of rehabilitation, DANODREN H rolls are spread with the nodules against the wall.

Inverted roofs with continuous paving:

In the case of walkable roofs with continuous paving, it will be laid on the thermal insulation with the nodules facing upwards and then the screed will be laid.
