Exterior waterproofing with ground contact

Exterior waterproofing
with ground contact

The best solution for professionals

Fast and easy application as well as a high level of safety along with short waiting times are the most important aspects that a modern waterproofing system must fulfil. The Remmers MB 2K system meets all these requirements. In combination with the Remmers International Guarantee (RIG), we not only offer the best possible product system for waterproofing structures with ground contact, but also an extra degree of security. Specialist companies that have been certified by Remmers as official RIG applicators have access to a variety of unrivalled benefits and additional services. After all, RIG specialist companies can work with and advertise to clients and building owners a 10-year product guarantee, which Remmers assures the specialist company. This creates trust and, as a unique selling point, is a major advantage in order procurement.

Exterior waterproofing on concrete surfaces with ground contact

MB 2K is notable for its multi-functionality, but the systems` economic efficiency is also unique. In addition to the fast and weather-independent drying of the material and the resulting short waiting times on the construction site, this is mainly thanks to the relatively low material costs.
Even when waterproofing building elements with ground contact against pressing water, a dry layer thickness of just 3 mm is sufficient – with no need for fabric reinforcement. Compared to conventional systems, which require a layer thickness of 4 mm, this saves material and the additional step of embedding the fabric.
A particularly effective application method for MB 2K is spraying. With suitable machine technology, spraying is a cost-effective alternative to manual application for surfaces starting from just 40 to 50 m².

1. Preliminary work
Chamfer the edge of the projecting foundation. Remove any components that could impair adhesion.

2. Levelling
Seal uneven areas and defects > 5 mm with WP DS Levell. Pre-wet highly absorbent substrates with water.

3. Priming
Apply an even layer of Kiesol MB. Pre-wet highly absorbent substrates with water. Leave out levelled areas.

4. Apply a scratch coat of MB 2K.

5. Embedding the joint tape
Apply MB 2K in the internal corner area and embed tape from the Tape VF series while still wet.

6. First waterproofing layer Evenly apply the first waterproofing layer of MB 2K.

7. Second waterproofing layer As soon as the first layer of MB 2K is dry enough to resist damage, apply the second layer.

8. Thermal insulation Once sufficiently dry, bond the thermal insulation over its entire surface area using MB 2K or 2K Remmers PMBCs.

9. DS Protect
Installation of DS Protect up to ground level.

Note
This system solution can also be used with other products based on the MB technology.
Exterior waterproofing on masonry with ground contact

People looking to build a basement can choose from a variety of construction methods. In most cases, concrete is chosen as the building material, as brick basements are no longer necessarily considered contemporary. But brick basements still exist – they have proven their worth for decades in terms of their load-bearing capacity and robustness and do not necessarily cost more than a concrete basement.
DIN 18533 also applies to brick basements. In terms of determining the water impact classes and other factors, there are no major differences compared to concrete substrates. Only when choosing a flexible polymer-modified thick coating it is necessary to work with a special agreement. However, this is not a problem, as Remmers has all the necessary suitability certificates for MB 2K.
The accompanying work, such as chamfering edges and rounding corners, does not differ from the procedure for concrete basements. However, special attention must be paid to protection against rear moisture and cross-sectional waterproofing, which does not exist in this form in concrete basements.

1. Preliminary work
Chamfer the edge of the projecting foundation. Remove any components that could impair adhesion.

2. Levelling
Seal uneven areas and defects > 5 mm with WP DS Levell. Pre-wet highly absorbent substrates with water.

3. Priming
Apply an even layer of Kiesol MB in the wall/base joining area. Pre-wet highly absorbent substrates with water. Leave out levelled areas.

4. Rear moisture protection
Apply an even layer of WP DS [basic] with a slurry brush to protect against backfacing water.

5. Sealing cove
Apply a sealing cove of WP DS Levell to the wet backfacing water protection and use a profiled trowel to profile in a radius of 50 mm.

6. Priming
Apply an even layer of Kiesol MB to absorbent masonry walls. Leave out levelled areas.

7. Scratch coat
Apply a scratch coat of MB 2K.

8. First waterproofing layer
Evenly apply the first waterproofing layer of MB 2K.

9. Second waterproofing layer
As soon as the first layer of MB 2K is dry enough to resist damage, apply the second layer.

10. Thermal insulation
Once dry, bond the thermal insulation over its entire surface area using MB 2K or 2K Remmers PMBCs.

11. Protecting the waterproofing
Installation of DS Protect up to ground level.
Strip waterproofing of joints on concrete with ground contact
To ensure the high-quality usability of even a waterproof concrete basement, water penetration through joints and cracks must be permanently ruled out. Only waterproofing products for which a suitability test has been carried out in accordance with PG-FBB may be used as joint sealants. MB TX 2K, a modern, flexible polymer-modified thick coating, meets this requirement..

1 to 1 – container packaging reduces preparation time and prevents mixing errors
Stable consistency with minimal dripping loss
No priming necessary – contact layer ensures bonding strength early on
Latest filler technology for streak-free, high-performance application

Fabric reinforcement for 2-layer application
Resistant to water pressure after one day
Long open working time delays skin formation and minimises blistering on the surface

Early resistance to rain means product can be applied in all weather
Can be applied from an air and substrate temperature of 1°C
1. Preliminary work
Chamfer the edge of the projecting foundation. Mechanically remove cement paste in the wall/base connection and on the face of the floor slab > 15 cm. Remove any components that could impair adhesion.

2. Levelling
Seal unevenness, defects and element joints > 5 mm with WP DKS rapid [basic]. Pre-wet highly absorbent substrates with water.

3. Scratch coat
Apply a bonding course of MB TX 2K to at least 15 cm on both sides of the joints and the foundation faces.

4. Embedding joint tape in the wall/base connection area
Apply MB TX 2K in the internal corner area and embed Tape VF 120 crease-free while still wet.

5. Waterproofing the wall/base connection
Apply two layers of MB TX 2K to the surfaces prepared with Tape VF 120.

6. First waterproofing layer in the area of cross-joints of element walls
Evenly apply a first waterproofing layer of MB TX 2K then embed Remmers Tex 4/100 reinforcing fabric.

7. Second waterproofing layer

8. Thermal insulation
Once dry, bond the thermal insulation over its entire surface area using MB TX 2K or 2K Remmers PMBCs.

9. Protecting the waterproofing
Installation of DS Protect up to ground level.
Reliable waterproofing of pipe lead-throughs

The higher the stresses, the more important it is to ensure the reliability of waterproofing in especially sensitive areas. This includes penetration points, which can prove to be an especially critical area. The pipe flange system has been proven to stay waterproof at immersion depths of up to a 5 m water column.
The pipe flange is permanently and securely bonded to the substrate and to the pipe. This configuration ensures an optimum bond between the pipe lead-through, the pipe flange and MB 2K / Remmers PMBCs.

1. Preparing the substrate
The substrate must be roughened, dry and free of dust. Fix the pipe so that it cannot move during the application of the waterproofing.

2. Applying flange adhesive
Apply adhesive to the pipe flange and the mineral substrate.

3. Attaching the pipe flange
Clip together the two half-shells around the pipe and push onto the substrate, twisting gently. Then waterproof the building structure with MB products or Remmers PMBC.
The top-performing protection and drainage system
The heavy-duty, three-layer protection and drainage system protects structural waterproofing to the highest level in accordance with DIN 18533 and DIN 4095.
Remmers DS Protect protects the perimeter insulation boards from moisture as a second, waterproof envelope on the basement wall waterproofing, ensures thermal stability and keeps basement walls permanently warm and dry. The transmission of shear forces from the soil to the waterproofing is reliably prevented by a sliding film perforated in the micrometre range.
The additional filter mat laminated onto the dimpled sheet ensures that water is filtered and drained. The weather-resistant filter mat prevents the dimpled structure from becoming clogged. In addition, the permanent action of the pressure exerted by the soil is distributed over a wide area.
Safe and highly durable according to DIN 18533:
Good water drainage (drainage system as per DIN 4095)
Resistant to weathering
Temperature-resistant from - 30°C to + 80°C
Compressive strength: approx. 350 kN/m²
Resistant for at least 25 years in natural soils with pH values between 4 and 9 and a soil temperature < 25°C
