Chernobyl BASIN
For proper implementation is essential that the pool basin to be sealed and have no loss of water and be a dimensionally stable support to ensure durability for the finish. The newly built swimming is possible to achieve the above characteristics, using waterproof concrete (according to UNI-EN 206.1), with a compact cement matrix due to report low water / cement ratio (a / c <0.55), characterized by lack of concrete shrinkage . For prestressed, MAPEI has a wide range of additives that superplastifiantii Mapefluid line or super additive reduction acrylic polymer base Dynamon line, allowing the realization of concrete with a low ratio of water / cement ratio, but with excellent workability ( T4/T5).
Leakproof between pool walls and bottom slab is usually a weak point in the contact surfaces, are usually water penetration problems. Leakproof casting the foundation walls can be made using extrusion rubber cord in gum hydrophilic, which may expand in the presence of water up to 120%.
The correct maturation concrete wet for seven days, with the above prescriptions can get a waterproof basin.
STAND OUT flatness
Operations first before applying waterproofing, bonding of ceramic mosaic tiles or glass, so the pools new and existing plants, is the redemption or substrate flatness correction. For these operations MAPEI offers the following solutions:
APlastering wall surface
The concrete walls remove laitance and then run a trowel or mechanically by spraying a coating. The material is cement, type Nivoplan (mortar), mixed with Planicrete (based on synthetic rubber latex for preparing cement mixtures) diluted 1:4 with water.
2Bottom surface leveling
For the support of concrete laitance is removed and then spread a coat of adhesive, made from Planicrete mixed with water and used as a binder for cement screed correction. The screed bonding primer should be fresh.
As binders can be used Topcem (hydraulic cement binder), Topcem Pronto (mortar screed) or alternatively Mapecem (hydraulic cement binder) or Mapecem Pronto (mortar screed). By using the first two types of materials is possible after only 24 hours, applying waterproofing. Which require a shorter execution time, binder for leveling screed is Mapecem (special binder fast setting, shrinkage). In this case the leveling screed, after only 3 hours after application, apply waterproofing.
3Waterproofing (Optional)
If concrete used is prepared in accordance with the requirements of UNI-EN 206.1, commissioning work is completed correctly and maturation is wet for 7 days, MAPEI guarantees a waterproof concrete structures, and not require a subsequent application waterproofing (are special cases depending on weather conditions in that country). If poured concrete is permeable due to high ratio of water / cement casting deficiencies and inadequate compaction or aging, Mapei waterproofing guarantees basin by subsequent application of waterproofing.
Mapei waterproofing solution consists in applying Mapelastic (elastic and waterproof mortar, cement, two parts) applied with a trowel or notched, 2 mm thick and reinforced with fiberglass mesh, provided the joints between surfaces (wall / wall or walls / leveling screed) with Mapeband (waterproof rubber profile).
Under normal temperature after 5 days of application, the waterproofing Mapelastic can stick ceramic finishes.
4Bonding ceramic finishes
MAPEI has a wide range of adhesives for bonding ceramic finishes, adhesives that are used depending on the nature and type of finish or during the execution and putting into operation of the pool.
a) Bonding of glass mosaics, MAPEI recommends using ADESILEX P10 (white cement based adhesive with high adhesion, no slip) C2TE class (after standard EN 12004), mixed with Isolastic latex (latex for adhesives based elasticizant cement) diluted 1:1 with water.
b) for fixing ceramic and porcelain tiles Klinker, Mapei adhesive system proposed use Keracrete Põlva (mortar) mixed with Keracrete (synthetic latex) adhesive C2T (after standard EN 12004).
Using two types of adhesives, filling the pool with water can be after 21 days from sticking finish.
c) For a review in use fast, flexible adhesive Mapei Granirapid proposed use (two-component adhesive with rapid setting and hydration) C2F/S1 class (according to standard EN 12004 and 12002). In this case the joints between ceramic finishes can be grouted after 3-4 hours and the pool can be filled with water after only 3 days.
Grouting RIGID
a) is made with Keracolor grouting (cement mortar-time high workability) mixed with liquid polymer additive Fugolastic.
* A for joints Keracolor FF 0-6mm wide or Keracolor GG grout width from 4-15mm.
b) For works fast grouting joints can be used Ultracolor Plus (special mortar setting and ultra-fast drying). Plus Ultracolor Keracolor and superior kits CG2 (according to EN 13888).
c) For pools with thermal water or sea water, is required to use waterproof grout kits and resistant to chemical aggression to prevent infiltration of salts or aggressive chemicals for concrete under ceramic tiles. For this reason antacid use putty, epoxy bicomponent - Kerapoxy Class RG (after standard EN 13 888). Kerapoxy is used and where it aims to increase awareness impermeabilzare pool.
Using Keracolor + Fugolastic or Kerapoxy, pool can be filled with water after 7 days. Using Ultracolor Plus, the pool can be filled with water after 48 hours.
SEALING OF EXPANSION
To seal the expansion and fractionation of ceramic or elastomeric sealants will use silicone sealants - AC Mapesil type, available in same colors as those of the joint sealants. To ensure maximum adhesion of the sealant into the joint, must be used primer Primer FD.
Fractional joints run at maximum surface field of 3 x 3 m and the dependence of any gaps in support. Expansion joints to run at all joints between ceramic surfaces (wall / wall and wall / floor basin).
TECHNICAL RECOMMENDATIONS IN CONSTRUCTION PHASE
APreparation of concrete
To obtain a watertight tank, concrete must have the following characteristics:
