Key components

The Myrtha modular system is based on the exclusive use of stainless steel for all structural components, except the standard floor of the pool, that is formed by a thin concrete slab, only providing a smooth support surface. The connection between the wall structure and the concrete floor is made through a steel base frame, fixed on the floor by means of strong chemical anchors. The pool walls are formed by pre-manufactured stainless steel panels factory treated with a permanently welded layer of hard PVC. All Myrtha stainless steel components are completely bolted together, instead being welded, thus there are no potential corrosion points in a Myrtha structure.

Buttresses, at each panel joint, allow the water pressure to be redirected on the slab, while the overflow gutter channel closes the wall at the top. Myrtha Pools use a number of PVC based proprietary techniques for the waterproofing of the laminated panel joints, pool tank and  concrete floor.

The base frame

The base frame that outlines the swimming pool is constructed of bolted steel sections that form the supporting structure for the Myrtha wall panels. It is mechanically connected firmly to the concrete footing with the use of chemical anchors. Rigidity is obtained with the use of numerous threaded bars (anchor bolts) which are anchored in the perimeter curb. The threaded anchor bolts also provide micrometric adjustment so that perfect levelling of the structure is achieved.

The wall structure

The pool walls are formed using sturdy prefabricated stainless steel panels. The front side of the panels are factory laminated with a permanently welded layer of hard PVC and the backside is covered with a clear coat laminate. The panels are bolted to the base frame and to each other. Similar to the aviation industry, steel welding is avoided, therefore eliminating any potential corrosion points on the Myrtha structure. The exclusive use of stainless steel for the structural components and PVC for waterproofing means that there is minimal risk of corrosion, with a reliable waterproofing.

The support buttresses

A vertical reinforcement along each joint and sturdy steel buttresses provide rigidity and strength to the structure. Each buttress is anchored to the concrete footing. The structure is both sturdy and elastic and is therefore ideal for installations with difficult ground conditions (i.e. seismic zones, unstable soils, etc.).

The overflow gutter

The Myrtha overflow gutter is made using the same material used for the wall panels and comes in a wide range of standard configurations. The gutter can be supplied with a “diagonal flow” design, that 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 requirements and the gutter dropouts can be supplied with silencers which virtually eliminate any noise.

Waterproofing

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.

Fittings

To allow for better waterproofing, all joints between the Myrtha panels are sealed with liquid PVC or reinforced PVC tape. The resulting joint is water resistant and optically uniform to the panel surface leaving an elegant wall finish.

The Traditional floor

The standard floor of a Myrtha pool is formed using a concrete slab, which is only needed to provide a smooth support surface. The slab is waterproofed using a reinforced PVC membrane produced specifically for use with swimming pools and protected with a surface lacquering. Myrtha pools can also be built without concrete, as the sturdiness of the stainless steel structure is assured through the engineered footings. A special matting, called SoftWalk, has been developed by Myrtha Pools to attain a smooth support surface for the membrane, which, at the same time, still allows for subsurface drainage. Each Myrtha pool can be supplied with this user-friendly feature.

Finishing

 

After the pool has been completely sealed and the overflow gutter installed, ceramic tiles are applied to the Myrtha surface. Gluing tile on a Myrtha stainless steel surface is much easier and safer than on concrete, as there is no possibility of water seepage from behind the tile and the traditional problem of poor long-term adhesion is therefore eliminated.
