External basement waterproofing

Wet basements can not be fully used and might endanger the building substance. We offer different methods for making basements permanently waterproof: From the outside with polymer-modified thick film sealants, mineral sealing slurries or a cold self-adhesive waterproofing membrane – whereby the entire external wall area is treated and thus protected from water penetration. In repair cases the external waterproofing can be installed even from the inside of the basement. This method is called “curtain injection”.

  2. Waterproofing pipe penetrations
  3. Preparing wall/floor junctions 
  4. Installing fillets
  5. Waterproofing layer
  6. Protection of the waterproofing layer

 

The use of bituminous products belongs to the standard solutions for the positive side waterproofing of basements. The systems are applied in a paste-like form and are therefore seamless. They are easy and safe to use and have crack bridging properties. On clean, solid, stable, gypsum free mineral substrates  Polysil TG 500 is applied as a primer. This immobilizes salts present in the substrate and the substrate is solidified. When preparing to waterproof on top of old bituminous coatings  Bitumen Primer is used.

Pipe and cable penetrations are sealed with the permanently plastic putty  KB-Flex 200 and protected by a layer of  KB-Fix 5. Alternatively these areas can be connected with a fillet of the respective thick film sealant or fitted with flanges.

To protect against water creeping behind the lower waterproofing connections  NB 1 Grey mixed with  NB 1 Flex is applied first. To prevent stresses in the waterproofing, rounded fillets are installed in the wall / floor junctions.

The actual area waterproofing is achieved using  Deuxan 2C in two layers applied by trowel.  Deuxan Professional can be spray applied. For greater ease of manual application use  Bikuthan 1C or 2C. The addition of  Glass Fiber Mesh is recommended in all thick film sealants and all applications. This allows for a better control of the coating thickness and safely absorbs movement in the building.

Before backfilling the positive side waterproofing is to be protected from mechanical damages and settling with  SD Protection and Drainage Sheet.

Mineral sealing slurries are especially robust waterproofing systems with extremely good adhesion to mineral surfaces. They are not affected by moist surfaces and become an integral part of the building structure on which they were applied. Mineral sealing slurries are paste-like and are applied seamlessly to the building element being waterproofed. They are easy and safe to apply and can be installed as rigid or crack bridging systems.

On clean, solid, stable, gypsum free mineral substrates  Polysil TG 500 is applied as a primer. This immobilizes salts present in the substrate and the substrate is solidified.

Pipe penetrations are waterproofed using  KB-Flex 200 and sealed with KB-Fix 5. Alternatively these areas are to be attached to the waterproofing using proper sleeves or flanges.

The actual area waterproofing is achieved using mineral based Elastic material in two layers. The installation of Flex Fabric is recommended between the mineral Based  Elastic layers to achieve an especially visco-plastic waterproofing layer. In areas especially in danger of water creeping behind the waterproofing such as wall-floor junctions, a substrate preparation with mineral waterproofing with
subsequently crystallizing agents. Suitable for positive side  mixed with mineral Based Flex is applied. To avoid stresses in the elastic waterproofing, rounded fillets made of  Repair Mortar are installed in interior corners.
