1. The base frame
The base frame that outlines the swimming pool is made up of bolted steel sections that act as the supporting structure for the Myrtha® wall panels. It is fixed firmly to the concrete footing by the use of chemical anchors and rigidity is obtained by the use of these numerous threaded bars which are fixed in the perimeter curb. The threaded bars also allow micrometric adjustment so that perfect levelling of the structure can be attained.
2. The wall structure
The pool walls are formed by the use of sturdy stainless steel pools panels. The pre-manufactured panels are factory treaded with a permanently welded layer of hard PVC, and are bolted onto the base frame and to one another. Similar to the aviation industry, the use of actual steel welding is avoided, thus there are no potential corrosion points in a Myrtha® structure. The exclusive use of stainless steel for the structural components and PVC for waterproofing means that there is minimal risk of corrosion and a high probability of leak free construction.
3. The support buttresses
At every panel joint (3 feet), sturdy steel buttresses give rigidity and strength to the structure. Every buttress is fixed to the concrete footing. The structure is both sturdy and elastic and is therefore ideal for installations with difficult ground conditions (e.g. seismic zones, or on unstable soils).
4. The overflow gutter
The Myrtha® overflow gutter is made with the same material that is used for the wall panels and comes in a wide range of standard configurations. The gutter can be supplied with a design (“diagonal flow”) which limits the evaporation of chemicals and reduces the noise of the falling water. The patented Myrtha® gutter grating has been designed to meet the strictest anti-slip and load regulations and the gutter dropouts can also be supplied with silencers which virtually eliminate noise.
In order to perfectly waterproof the Myrtha® structure, a rigid PVC profile, specially designed, is used to seal the panel joints. The profile is bonded through a special liquid PVC that also penetrates in the joint between the panels, guaranteeing a perfect, long lasting sealing. The resulting joint is extremely resistant and optically uniform to the panels surface.
6. Protective reinforcements
In order to allow for better waterproofing all joints between the Myrtha sections are welded with a liquid PVC or a reinforced PVC tape. The result joint is extremely resistant, optically uniform to the panel surface and aesthetically pleasant.
7. The Traditional floor
The standard floor of a Myrtha® pool is formed using a concrete slab, which needs only to provide a smooth support surface. The slab is waterproofed by a reinforced PVC membrane, produced specifically for use with swimming pools and protected with a surface lacquering. Myrtha Pools® can be built without concrete as the sturdiness of the stainless steel structure is assured through the engineering of the footings. A special matting has been developed by Myrtha® to attain a smooth support surface for the membrane, whilst at the same time allowing sub surface drainage. In any type of Myrtha® pool, this floor can be supplied with a user friendly “Softwalk” floor. The soft floor is ideal for pools that have multi-purpose use with shallow water activity and for shallow water pools with toys and/or with beach entry. A Myrtha® floor can be easily marked with racing lanes or safety markings using PVC membrane or special purpose mosaic tiles.
