Outer water proofing

Durable system solutions for each application case

The effect and durability of waterproofing for buildings depend on different factors. This includes one of the most important factors, i.e. the selection of the correct waterproofing system depending on the type of water load. It is the correct classification of the load that allows sustainable functional waterproofing of buildings.

Restoration of bitumen subsurfaces

Subsequent outer water proofing that has contact with the ground requires greater care during planning and implementation. After exposing the part that needs to be waterproofed, the type and quality of the existing waterproofing needs to be assessed. In the case of bitumen-based old waterproofing, the firm connection to the subsurface needs to be checked before work is commenced, and any loose, adhesion-inhibiting components need to be removed. It is only necessary to completely remove the old waterproofing in some cases. To cater for the moisture load in the wall-sole connection, the old waterproofing in this area needs to be completely removed down to the mineral subsurface. The new hybrid waterproofing MB 2K is an easy way to create a effective bonding course and an optimum adhesive bonding between new and old waterproofing.

1 Remove the old coating

All the old waterproofing in the heavily exposed area at the footing needs to be removed down to the mineral subsurface.

2 Preliminary work

Break the edge of the projected foundation. Adhesion-inhibiting constituents must be completely removed.

3 Priming

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

4 Bonding course

Apply the Kiesol bonding course with WS Sulfatex within the response time.

5 Equalisation

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

6 Tight cove

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

7 Bonding course/scratch coat

Apply a thin layer of MB 2K with a trowel across the entire old waterproofing.

8 Surface waterproofing

After the bonding course reacts with MB 2K, apply the waterproofing in two work steps.

9 Heat insulation

After an adequate drying period, adhere heat insulation across the entire surface of the waterproofing with MB 2K.

10 DS Protect

Assembly of the DS Protect up to the ground level.

Subsequent waterproofing of mineral subsurfaces

One of the most reliable solutions for subsequent restoration of a wet cellar is to waterproof the outside cellar wall that has contact with the ground. The WTA information sheet 4-6-12/D ‘Subsequent waterproofing of parts that have contact with the earth’ contains explanations about installing this kind of waterproofing. In addition to the detailed damage and/or building diagnostics and the preparatory steps for the subsurface, the information sheet also addresses the various sealing materials like polymer modified, bituminous
thick coating or mineral water proofing grouts. For decades, Remmers has been supplying product systems that precisely match the WTA specifications. Numerous restoration reference objects demonstrate the optimum interaction of the system components made of mineral waterproofing grouts, water proofing filler and the bitumen-based surface water proofing. Waterproofing also needs to withstand the high requirements in the base area. This is where a variety of loads come together. Waterproofing must be positive fitting and reliable in the base zone / splashwater areas, transition area and areas that have contact with the ground. This means that, according to the familiar Remmers method, the splashwater areas in the base need to be waterproofed with mineral grouting systems that are highly sulphate-resistant, then a safety zone with an overlap of at least 20 cm needs to be created and the areas that has contact with the earth needs to be sealed to the optimum with PBD 2K.

1 Preliminary work

Break the edge of the projected foundation. Remove the adhesion-inhibiting components.

2 Priming

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

3 Bonding course

Within the reaction time of the Kiesol, apply WP Sulfatex as a bonding course in a “wet-on -wet” method.

4 Equalisation

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

5 Tight 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

After drying the equalisation, apply the first water proofing layer with MB 2K.

7 Second water proofing layer

As soon as the first layer can no longer be damaged, the second layer of MB 2K can be applied.

8 Heat insulation

After an adequate drying period, adhere heat insulation across the entire surface of the waterproofing with MB 2K.

9 Spritz/base render

Add SP Prep to a separate or the last still fresh layer of calcium carbonate as an bonding course for SP Top SR.

10 Base render

Apply SP Top SR after 24 to 48 hours.

11 Plaster sealing

Seal the pores in the base render with MB 2K. Apply the waterproofing min. 5 cm above the ground level.

12 DS Protect

Assembly of the DS Protect up to the ground level.
