Basement waterproofing

Proven systems for usable cellars and high-quality housing

If the damaged cellar wall is not freely accessible due to covering or rebuilding work, subsequent interior water proofing is a real alternative. If the product systems are ideally matched, even high-quality housing can be created in this way.

Excellent reliability for high-quality use

For the purposes of ensuring quality and durability, careful preparation of the surface is essential. The WTA information sheet 4-6-12/D contains extensive advice here. Thanks to the interaction of individual system modules, such as surface pretreatment/strengthening, inner water proofing, horizontal impervious layer and energy-adapted protection systems, it is possible to create high-quality usable housing in old cellars.

1 Preliminary work

Remove older render and coats up to 80 cm above the damage zone and scratch out damaged joints 2 cm deep.

2 Priming

Apply Kiesol (1:1 with water) evenly on the prepared subsurface. Pre-wet heavily absorbent subsurfaces with water.

3 Bonding course

Apply the Kiesol bonding course made of WS Sulfatex with the wide brush within the response time.

4 Equalisation

Equalise all unevenness with WP DS Levell in a wet-on-wet method.

5 Sealing cove

Apply a tight cove with WP DS Levell using a tight cove trowel in a “wet-on -wet” method.

6 First water proofing layer

Apply the first water proofing layer of WP Sulfatex with a wide brush onto the equalisation layer.

7 Second water proofing layer

Two layers of calcium carbonate onto the first water proofing layer “wet-on -wet”. If necessary, several layers may be necessary depending on the loading conditions.

8 Spritz

Add the mixed and still fresh WP Sulfatex spray mortar until all is covered.

9 Restoration render coat

Apply SP Top WD rapid after 24 hours.

10 Restoration render - completion

Once rigid, rub down or prepare the SP Top WD rapid with a sponge float and a little water, and then rework with SP Top Q2.

For dry and watertight usable cellars

Time is money! It is therefore worthwhile opting for fast solutions for cellar rooms used as cellars. Solutions that do not aim for maximum (living) comfort but efficient completion times. The Remmers repellent mortar delivers this solution. In cellars that are purely used as cellars, the product can be used in combination with the capillary filler iQ-Top SLS alternatively to the classic Kiesol system comprising grouts and high-performance restoration render.

Application examples

A system solely for usable rooms with normal moisture levels because moisture sorption through a capillary-active filler is only reliably possible at low temperatures or vapour pressure gradients
Store rooms, stock rooms, garages, bicycle cellars

Properties

Fibre-reinforced water-permeable render
Tested up to 2.5 bar (this corresponds to a 25 m water column!)
Considerably higher speed because denseness and equalisation through one product

Advantages

Special system for basements
Efficient model thanks to less and simple work steps
Equalisation and sealing only with repellent mortar

1 Surface treatment

Remove older render and coats up to 80 cm above the damage zone and scratch out damaged joints 2 cm deep.

2 Priming

Apply Kiesol (1:1 with water) evenly. Pre-wet heavily absorbent subsurfaces with water.

3 Bonding course

Apply the Kiesol bonding course made of WS Sulfatex with the wide brush within the response time.

4 Sealing cove

Apply WP Top [basic] with a tight cove trowel “wet-on -wet” in the transition area between the wall/floor.

5 Equalisation

Equalise all unevenness with WP Top [basic] in a wet-on-wet method.

6 Sealing layer

Apply a water proofing layer of approx. 20 mm made of WP Top [basic] in the roughened equalisation. Roughen the adequately stiffened surface to improve the grip of the subsequent filler.

7 Surface finish

Apply a layer of iQ-Top SLS of approx. 5 mm after 2 – 7 days.
