Roof Slab Waterproofing Details

Typical waterproofing details of foundations above the roof slab shall be followed as per approved shop drawing.

Roof slab waterproofing details.

Of the most critical areas of roofs especially when the waterproofing system. Perimeter foundation insulation is required in colder climates to reduce the heat loss from a slab on grade to the below grade foundation wall. Winkler one is a high performance waterproofing solution for flat roofs that encompasses all the positive features of a liquid applied roof system. Topical sealers can be made from acrylic epoxy and polyurethane based materials.

Waterproofing bituminous sheets used in low slope roofs. Winkler one material cost may be higher than some liquid applied membranes however the labor cost to apply it is lowered due to the reduced time of application steps and the details treatment efficacy. Once the waterproofing membrane is laid drying out of the structural slab will mostly take. Unauthorized entry shall be restricted to the waterproofing areas.

Waterproofing bituminous sheets applied in either single or multiple layers are one. Being trapped between the reinforced concrete roof structure and membrane. On completion of waterproofing membrane and before undertaking any further activity it shall be tested by plugging the outlets and flooding 50mm above the highest point by hose and leaving flooded for twenty four hours before draining off. Large amount of water vapour can evaporate from reinforced concrete or a wet screed.

The sealer is impermeable provided it is applied correctly and forms a waterproof membrane around the concrete preventing moisture from entering the concrete.
