Water is a sports and adventure space. That is why there are so many swimming pools, sports and leisure pools. Be it a sports pool, treatment pool or teaching pool or other, all types of pools represent a high technical challenge with regard to their functionality and demand longevity in terms of their life cycle. In new builds and renovations, the same parameters apply for appropriate functionality. Furthermore, in the course of expanding or making a pool more attractive, a refurbishment of the existing parts of the building is almost always considered. Continuous updating of the relevant technical regulations to their status today as well as the increasing demands for hygiene, health protection and sustainability have resulted in a significant rise in quality standards. On the one hand, this has implications for all those involved in the execution of such construction projects, and on the other hand, it requires experienced partners throughout the entire planning and construction process, also taking into account the expected investment costs.
Particularly for the commercial sector, the requirements are increasing with regard to digitalisation in the construction industry. In addition to the digitalisation of business models, this also includes the coordination of work assignments. Digital planning (BIM), communication via mobile devices and the availability of offers for the economic use and maintenance of real estate are essential components of a forward-looking construction system.
The SCHOMBURG group offers swimming pool construction trades tried and tested, sealed system solutions - from the injection hose and the two-component mineral-based sealing slurry, right to the chemicallyresistant joint mortar. These make it possible for the planner and the execution company to impress the developer with reliable planning and execution, especially developers who have already had to complain about damage to their properties and therefore show a particular sensitivity for possible sources of error. The expertise acquired over decades of development work across SCHOMBURG construction system materials offers the qualified specialist company significant added benefits. Those involved in construction benefit from competent advice on all aspects of efficient application technology, be it in relation to applications that comply with regulations or to special constructions and timeconsuming work. In the area of swimming pools, particular attention must be paid to the relevant waterproofing technology because there is no room for failure in the highly stressed tank bodies. Rising demands necessitates that the tiling trade work with the highest quality and efficiency. It is therefore not without good reason that swimming pool construction is described by skilled specialists as the “supreme discipline” of the tiling and waterproofing industry. It is frequently consequential damage resulting from mistakes in the waterproofing technology of earlier generations that after extended downtimes or periods out of use - provides the impetus for thorough renovation of defective existing swimming pools. However, such renovation measures are generally also seen as a real opportunity. It is not uncommon for developers to utilise pending substantial alterations as a chance to enhance the appearance of the project. As a result of this, the renovation project often looks like a new build on the old site.

“Standards-compliant” waterproofing in combination with tiles and boards in the different areas of a pool With the waterproofing standards DIN 18534 “Waterproofing for indoor applications” and DIN 18535 “Waterproofing of tanks and pools”, it is now possible to seal all areas of a swimming pool in compliance with standards for waterproofing in combination with a covering of tiles or boards (AIV). Until July 2017, the basis for planning waterproofing in swimming pools was generally the previous waterproofing standard DIN 18195 and the ZDB bulletins. While the various areas of use were previously subdivided by o load classes in the ZDB bulletins, the differentiation in DIN 18534 and DIN 18535 is made by water impact classes. In DIN 18534 “Waterproofing of interior rooms”, waterproofing is described with the following material groups: •W aterproofing with waterproofing materials in sheet form •W aterproofing with melted asphalt and asphalt mastic •W aterproofing with liquid application waterproofing materials in combination with tiles and boards (AIV-F) •W aterproofing with waterproofing materials in sheet form in combination with tiles and boards (AIV-B)
• Waterproofing with waterproofing materials in panel form, in combination with tiles and boards (AIV-F) In DIN 18535 “Waterproofing of tanks and pools”, waterproofing is described with

• Joint sealing tapes • Sealing collars • Reinforcing inserts • Thin-bed mortar These must be explicitly named in the test certificates of the planned waterproofing system to be used. In accordance with DIN 18534, all surfaces per the water exposure classes W2-I and W3-I must be sealed. However, with water exposure class W1-I it is only necessary to seal substrates and wall surfaces manufactured from water-sensitive building products, or water-resistant building products if these are located directly behind water-sensitive building products, for example insulation. In the case of wall surfaces exposed to water, waterproofing must be applied a minimum of 20 cm above the water intake point or above the height of the anticipated splash water area. If it is only necessary to seal the substrate or floor, e.g. changing areas or the foyer of a swimming pool, the waterproofing layer must be applied min. 5 cm above the upper edge of the top floor covering. All installation or assembly parts in the area of the waterproofing, e.g. drains, gutters, shower fittings, as well as all assembly parts in a pool that is to be waterproofed must have a min. 5 cm wide sealing flange running all round according to the new waterproofing standards. While waterproofing with AIV-F, such as crack-bridging, cementitious waterproofing slurry is possible in all neighbouring water exposure classes DIN 18534 (W0-I to W3-I) and DIN 18535 (W1-B to W2-B), waterproofing with waterproofing materials in sheet form in combination with tiles and boards (AIV-B) is only applicable on surfaces with water exposure classes W0-I to W2-I as well as on wall surfaces of water exposure class of DIN 18534. Bonded waterproofing (AIV-B) does not apply in DIN 18535, the standard for waterproofing tanks and pools.

Water exposure classes W2-I and W3-I, high to very high water exposure
Swimming pool surrounds · Shower syst ems and sanitary rooms · Sauna areas In wet areas whose wall or floor substrates are classified in water exposure classes W2-I or W3-I per DIN 18534, only subfloor structures made of water-resistant building materials may be used (see tables pages 4 + 5). With AIV-F, polymer dispersions (DM) are only permitted on wall surfaces up to water exposure class W2-I and floor surfaces up to W1-I. Crack-bridging, cementitious
waterproofing slurry (CM) and reaction resin (RM) may be used on wall and floor surfaces in all water exposure classes. Waterproofing with waterproofing materials in sheet form are permitted in combination with tiles and boards (AIV-B) for wall surfaces up to water exposure class W3-I and floor surfaces up to water exposure class W2-I.

Liquid application waterproofing materials used in pools include crack-bridging, cementitious waterproofing slurry (CM) or reaction resin (RM). After completion and before producing the ceramic cladding, concrete pools that are furnished with bonded waterproofing should be subjected to leak-tightness testing for a minimum of 14 days, during which the pool should be filled with chlorinated water continuously. During this time, the pool water level must reach the maximum water level. Before tiling with hydraulically hardening thin-bed mortar, the drying time of the concrete structure must be at least 6 months drying time. In addition, the surfacing material bedding must cover the whole area insofar as possible. With laying formats > 10 × 10 cm, apply the combination method (Floating-Buttering method).

Brine and seawater baths · Steam ba ths · Thermal and mineral baths The allocation of suitable SCHOMBURG composite waterproofing systems to the water impact classes of the waterproofing standards DIN 18534 and DIN 18535 can be found in table form at www.schomburg.de. Permissible installation surfaces and substrates are listed in Tables 2 and 3 of the ZDB bulletin “Bonded sealing (AIV)” – November 2022. As already described with the swimming pools filled with water per DIN 19643, in thermal, mineral, brine or seawater pools, it is possible to use mortar or levelling compounds (e.g. PCC mortar = Polymer-CementConcrete mortar) as a pre-blended dry mortar as an alternative to cement plaster from the mortar group PIII CS IV per DIN EN 998-1 without the addition of lime hydrate. Polyurethane- or epoxy resin-based reaction resin systems are applied as liquid application waterproofing materials in thermal, mineral, brine or seawater pools, and in the neighbouring wet areas with chemical exposure. The AQUAFIN-EPOX reactive resin sealing system used in these areas is based on epoxy resin. Epoxy resin-based sealing systems offer greater processing reliability and a lower health risk during application. Furthermore, the tested, two-component, reactive curing, flexible waterproofing slurry AQUAFIN-RS300 can be used as AIV in areas in and around bathing pools where the filling water is aggressive to concrete, up to exposure class XA2 per DIN 4030.

CAPILLARY-BREAKING JOINT In the case of pool edge systems with a high-lying water level, exposure of the covering on the lower-lying pool surround to the effects of capillary water must be avoided. In order to prevent water leakage, the capillary-breaking joint presented in the “Wiesbaden” and “Finland” pool edge systems is applied with ASODUR-SG2, mixed with quartz sand in a mix ratio of 1:1 parts by weight.
MOVEMENT JOINTS BETWEEN THE POOL EDGE AND SURROUND The tank body is often separated from the remaining loadbearing building components of a swimming pool by construction measures. A tried and tested construction variant, for example, is the flexible bedding of the swimming pool surround on a reinforced concrete pool edge base. The structural separating joint that arises here must be professionally protected against water ingress into the plant rooms below.

During the bonded waterproof system application and laying works, the joint is bridged with the joint tape technology compatible with the waterproofing system, as shown. For surfaces with water exposure class W3-1, according to DIN 18534-3, additional cut protection must be planned and installed for movement, connection and bay sizing joints.

The Wiesbaden pool edge system finds application with high or low-lying water levels. The high Wiesbaden gutter shown here is an overflow system with specially shaped ceramic parts. The water level is at the height of the pool edge. Whereby the ceramic overflow gutter is arranged outside the pool and will be covered with a grate.
14 schomburg.com
The Finnish gutter is also a pool edge system with a highlying water level. The pool edge is applied with a beach-like gradient. The water level sits at the height of the overflow edge arranged outside the pool. So, the Finnish gutter system enables numerous design options, in particular with rounded pool geometries.
The pool edge construction depicted here, with low-lying water level, has proven outstanding in the design of therapy pools with brine. The water level is approx. 25-30 cm below the top edge of the pool and the swimming pool surround is lowered relative to the water level for patient care. schomburg.com 15
Pool edge waterproofing for unseal ed waterproof pool constructions If no complete sealing of the waterproofing basin construction is planned, care must be taken when “sealing” the swimming pool surrounds to the basin to ensure that it is not possible for water to migrate behind this. Migration behind the waterproofing can lead not only to leaks but also to an impairment of the adhesive bond of the AIV-F to the substrate. In order to counteract this, a so-called “receiving groove” is usually set into the concrete structure in the area of the pool edge, into which the waterproofing is fed in the swimming pool surround. DIN 1045 allows water to penetrate up to a maximum of 5 cm into the waterproof concrete construction. Experience shows that water usually penetrates 15 - 25 mm into the concrete. With the subsequent cutting of an approx. 3 cm deep “receiving groove”, migration behind the waterproofing can be prevented. However, this type of migration protection for the waterproofing reduces the thickness of the concrete cover in the area of the groove by more than half, which poses possible risks for the corrosion protection for the reinforcement at this point. If the construction of the so-called “receiving groove” is not included in the contract for the structural work, additional legal problems arise, as the cut in the waterproof concrete construction interferes with the preceding trade.

In order to prevent damaging influence due to water ingress behind the waterproofing layer on the bonding of the waterproofing, we recommend the following possible design variants (see drawings): • Application of a two-layer primer with the water-insensitive epoxy resin primer ASODUR-SG3-thix • Producing the capillary grouting behind the Wiesbaden channel with capillarytight epoxy resin mortar at full depth as far as the upstand surface (concrete) of the gutter blocks. With this variant, the waterproofing ends approx. 10 cm above the upstand surface of the gutter blocks on the concrete. With these two variants, the reservations in terms of building law and construction relating to designs with a so-called “receiving groove”, can be eliminated.
With these design variants as in the two illustrations, the water penetrating the concrete by capillary action must travel at least 30 cm in the concrete, parallel to the concrete surface, in order to reach the contact zone of the composite waterproofing (AIV). This can be excluded with a probability bordering on certainty if the waterproof concrete construction is carried out professionally.

emulsified epoxy resin ASODUR-V360W. The silk-matt surface of this sealing resin prevents the screed chalking, reduces wear and improves the cleanability. Whereby the surface structure of the screed remains largely intact. For a smooth or slip-resistant coating as well as for improved hygiene or work safety, the application of the pigmented
approx. RAL 1015
2-component EP coating ASODUR-B351 is recommended. This is highly chemically resistant and withstands mechanical loading, does not contaminate food and is plasticizer resistant. The EP-floor coating ASODUR-B351 also satisfies increased demands for a nonslip surface (R9–R11) and a particularly dense surface. In addition to the legal regulations in the workplace ordinance and workplace regulations, certain construction requirements also apply to recreation rooms. Furthermore, personal injury due to VOC emissions from synthetic resin coatings in occupied rooms, must be avoided. The vapour permeable sealing product ASODUR-V360W satisfies the assessment scheme of the German Committee for HealthRelated Evaluation of Building Products (“AgBB”) for the reduction of indoor air pollution, and is therefore ideal for industrial and commercial indoor spaces. After sealing or coating are complete, thorough cleaning takes place with the industrial floor cleaner ASO-R008. This cleaning concentrate improves the cleanability during subsequent maintenance cleaning.

Waterproofing of buildings WATERPROOFING BUILDING COMPONENTS IN DIRECT GROUND
WALL/FLOOR TRANSITION
Moisture in buildings is a major cause of building damage. Errors in the planning and execution of waterproofing – in particular the incorrect formation of existing building features – are critical here. In order to protect building components against water penetrating from the ground and to avoid damage in indoor areas, the exterior surfaces are sealed and insulated. The decisive standard here is DIN 18533.
INTERSECTIONS
Connections with intersections or similar must be established with floating or fixed flange constructions, adhesive flanges or suitable joint sleeves for example, depending on the water exposure class. In water exposure class W1.1-E, the connection can be established with AQUAFIN-RB400 in conjunction with the ADF pipe gasket for example.
In the area of the wall/floor transition or structural movement joint, waterproofing from AQUAFIN-RB400 for example is further reinforced by ASO-Dichtband-2000-S.
EXTERIOR WATERPROOFING
Exterior waterproofing covering the whole area of the surfaces in direct ground contact is applied with the aforementioned products, depending on the water exposure class. Waterproofing is fully covering and free of defects, and takes place in a minimum of two application steps with the required minimum dry film thickness. With water exposure class W2.1-E, it is necessary to document the layer thickness checks (quantity, position, result) and material rate of consumption, as well as the results of the drying test.

WATERPROOFING CONSTRUCTION JOINTS
Waterproof concrete constructions (concrete in accordance with DIN EN 206-1 and DIN 1045-2) are produced as a sealed tank. However, construction or building sequencerelated joints generally require joint sealing. Various waterproofing systems are available for construction joints, e.g. compressible injection hoses, swelling joint tapes, etc. AQUAFIN-CJ can be used to seal such joints depending on the requirements. With the injection hose AQUAFIN-CJ1 the reinforcement arrangement in the concrete is not impeded and upstands are avoided. After concreting, the waterproofing measure is implemented with AQUAFIN-P4. This is a solvent-free 2-component elastic PUR injection resin that is tested for building approval in conjunction with AQUAFIN-CJ1. Alongside injection hoses, expanding jointing bands like AQUAFIN-CJ6 are also a suitable method for sealing construction joints.
Due to the simple fastening method, they can also be adapted to awkward joint shapes. The thermoplastic elastomer contained in the swelling joint tapes reacts upon contact with water and their volume increases. Due to the resulting contact pressure, the material then seals the construction joint against the adjacent concrete flanks.

International standards and regulations In many countries, a range of regulations apply to construction works and in particular to the construction of swimming pools and their tanks. In Europe, these are largely regulated by European Standards (EN).
The waterproofing of swimming pools in combination with bonded tiled finishes is regulated in Europe by EN 14891. We confirm compliance with this with the following test certificate:
Such testing of waterproofing bonded with tiles also applies in Belgium and we are able to provide verification accordingly.
