Fairlock’s Betaloc pool during construction HEAVY DUTY HYBRID
The remarkable Betaloc™ system from Fairlocks Pool Products is designed for vertical and horizontal reinforcement, creating excessive strength both compressively and laterally, which can be used for more demanding projects together with general everyday constructional needs.
Incorporating a unique dry build process, Betaloc™ allows the blocks to be laid to a running bond in a combination of half and third lengths. Dry building means that when stacking the blocks there is no need to mortar the joints together, thus saving time and extra cost implications. Using the Betaloc™ Shuttering Block also allows non- masons to construct with them, again saving on cost. The basic fact is that less skilled persons on site can build footings, foundations and many other applications using the Betaloc™ Blocks while skilled masons can concentrate on other areas of the project, creating a faster rate of construction. Betaloc™ Blocks are 450mm long x 225mm wide and high, each block weighs approx 20kg, which conforms to the HSE guidelines for single man repetitive lifting. Although Betaloc™ Blocks are lighter than most conventional hollow blocks and clearly more versatile, they can still accomplish minimum compression strength of 7.3N/mm². There are many distinct advantages in using the Betaloc™ Block to that of using a conventional dense hollow block: • Unique design allowing stronger reinforcement both laterally and compressively
• Dry stack building process • No mortar required • Non-mason friendly • Full structural calculations available (up to 2m wall depth)
The first course of Betaloc™ Blocks must be set on a bed of mortar with the vertical re-bars in place as with any other conventional hollow block, but from there, they can be stacked dry up to the required height, laying the horizontal re- bars in place before starting a new course. When the wall has reached the desired height and is plumb, it is ready for the concrete to be poured as you would a normal hollow concrete block

construction. The concrete then falls down the cavities to ensure there is no segregation, which in turn produces a wall with a magnitude of lateral and compressive strength. Fairlock’s Paul Webb comments: “When using the Betaloc™ system the pool builder or contractor effectively combines the ease of dry block building with the strength of a concrete build. Since introducing Betaloc™ in 2007 we have supplied many pool companies and the product has proved to be immensely popular with everyone we have worked with.” Fairlocks recommend that walls exceeding a height of 1.5m should be filled with concrete every 900mm.
David Clark, Managing Director of the Lifestyle Group realised the versatility of sprayed concrete to provide the complex specification required for pool owners. Unable to obtain the standards and more importantly the accuracy necessary, Guntek Ltd was formed in 1990 by purchasing pumping equipment from America.
Within a short space of time Guntek was constructing pool shells for many of the major pool companies in the UK who appreciated the quality of their shells, many of those companies still credit them with that accolade today.
MODULAR STRUCTURAL PERFORMANCE Concrete swimming pools are without doubt an excellent leisure investment so say Cheshire based Anderton Concrete Products Ltd. The company is the UK manufacturer of Stepoc; a system of highly- engineered and dimensionally co-ordinated building modules which are designed to readily accept horizontal and vertical reinforcement for use where structural performance is the prime consideration. Stepoc’s unique design enables the reinforcement to be placed in the optimum position to ensure that maximum strength is achieved just where it’s needed. Stepoc is then filled with concrete, which is poured down through the inter-connected cavities in the blocks. The block’s unique design creates a cascade or waterfall effect which ensures a smooth filling of the poured concrete, forcing out air and eliminating segregation, to create walls which have immense compressive and lateral strength. There is a delicate balance which must be met
with ground development, concrete foundation and structural integrity. Therefore Stepoc combines the ease of block-work with the versatility of in-situ concrete and yet is faster to apply than both, making it an ideal component in fast track construction for: • Swimming pools • Retaining walls • Basement walls • Shear walls • Laterally loaded panels
Whether it’s a swimming pool or indeed, a retaining wall around the pool Stepoc is an excellent way to enclose raised gardens and prevent erosion too. The engineering team at Anderton Concrete provides technical advice working with all associated parties offering valuable assistance in selecting and developing the most appropriate solution depending on a number of factors. From the outset these considerations will be factored into the final geotechnical solution when presented. So it would seem; based on concrete evidence, that well built, endurable and versatile concrete pools are as desirable an asset as they ever were. spn
