All external areas are subject to severe environment conditions which might affect our internal dry areas specially all related to leakage. Waterproofing the concrete structure is essential to avoid problems such as oxidation of steel and damages related to water infiltration.Weber proposes several waterproofing solutions for roofs ( exposed, covered, planted, insulated).



Waterproofing for roof systems

Waterproofing of exposed roofs

Roofs are generally exposed to heavy weather conditions and require specific waterproofing solutions. weber offers two solutions:

1. Waterproofing with polyurethane liquid membranes providing flexibility, solar reflective and easy to apply and maintain features.

2. Waterproofing with bituminous sheet membranes and cement based coating with resistance to indentations caused by traffic, better crack bridging and suitable for large flat roofs.

Waterproofing systems for rooftop garden & planted areas

Roof must be waterproofed durably and frost resistant. If you are growing plants on it; whether you will grow plants on containers, raised beds or on the roof itself. Waterproofing system is a must and should be first step to terrace garden construction as it protects the roof from leaking. Waterproofing should cover up the entire surface of the roof.

Thermally insulated roofs

weber offers two systems as follows:

1. Inverted roof system : consist of a waterproofing layer, insulation layer and finishing layer. with this arrangement , the roof waterproofing membranes remain protected from mechanical damage and against the direct influence of external factors. The temperature on the waterproofed surface remains stable regardless of the weather conditions.

2. California system : is an insulated walkable flat roofing, finished with white high reflective aluminium foil self-protected membrane with double layer waterproofing application in full bonding. It gives a full waterproofing, thermal and sound solutions for roofing.

Waterproofing for accessible terraces

  1. Bituminous sheet membranes

    When applying the bituminous sheet membranes , Biflex PL (SBS bituminous membrane) or Biplas PL (APP bituminous membrane) are the recommended products. Care should be taken for the stacking of materials. The rolls should be dispersed uniformly. They should be stored standing up. Any horizontal stacking of bituminous membranes on top of each others, might damage the materials, especially under sun heat.

  2. Polyurethane liquid membrane

    When applying the polyurethane liquid membranes , prime first with weberdry prime 310 PU and then apply the weberdry 360 PU. Once the first layer is applied and after 12-18 hours (not later than 48 hours) , apply another layer of weberdry 360 PU.

  3. Protection

    Geotextile white PET to protect the waterproofing membrane used,and gravel or loose tiles can be laid over the protection (soft protection) / Geotextile white PET for protection of the waterproofing membranes used, and webercol floor in order to proceed with tiling (Hard protection) /Geotextile white PET for protection of the waterproofing membranes used, extruded polystyrene o thickness depending on the amount of thermal conduction designed (Thermal protection)
