Above Ground
Fibreglass Pools.
Maxi Rib technology lets a Compass fibreglass pool be installed fully or partially above ground — the ideal solution for sloping sites, difficult blocks, split levels and tricky backyards where a traditional inground pool isn't possible.
Three Ways to Install an Above Ground Fibreglass Pool
Maxi Rib technology makes all three options viable on virtually any site. Whether you have a flat yard, a sloping site or a difficult block, we'll assess your property and recommend the right above-ground or inground approach.
Fully Inground
The standard installation for flat or gently sloping blocks. The pool sits entirely below ground level — the most common installation for Sydney suburban backyards.
Best for: flat blocks, standard suburban lots
Partially Above Ground
Part of the pool sits above the natural ground level — ideal for sloped blocks where full excavation would be expensive, or where a raised pool integrates with deck and entertainment areas.
Best for: sloped blocks, split-level homes, deck integration
Fully Above Ground
The entire pool sits above ground — made possible exclusively by Maxi Rib technology. Creates dramatic architectural installations, courtyard pools and rooftop possibilities.
Best for: courtyards, difficult sites, architectural feature pools
Maxi Rib: The Technology Behind Above Ground Fibreglass Pools
Standard fibreglass pools rely on surrounding soil for structural support — which is why they can only be installed inground. Maxi Rib is a proprietary structural rib system that runs the full length of the pool shell, providing the structural support to hold water load without soil backing.
This pioneered approach by Compass means Maxi Rib pools can stand above ground, sit on raised platforms, feature infinity edges with holding tanks below, and handle difficult site pool installations that would be impossible for any other fibreglass pool — including steep sloping sites and tight, awkward blocks.
Full-Length Structural Ribs
Proprietary rib system provides structural integrity without soil support.
Infinity Edge Compatible
Vanishing edge installations are made possible by Maxi Rib's structural capability.
Glass Wall Compatible
Above-ground walls create the perfect opportunity for acrylic glass panels.
Any Shape Available
Maxi Rib is available across all 10 Compass pool shapes and ~40 sizes.
Pools for Sloping Sites & Difficult Blocks
One of the most common questions we get from families on sloping sites and difficult blocks across hilly Sydney suburbs is whether their property is even suitable for a pool. The answer, with a Compass Maxi Rib above-ground fibreglass pool, is almost always yes.
By installing the pool partially above ground on the low side of the slope, we can create a level pool on even the steepest sloping site — without expensive excavation or retaining into the hillside. On a difficult block, the above-ground wall becomes an opportunity — for decking, glass panels or a dramatic raised pool.
Site Inspection Is Essential
Every sloped block is different. Book a free site inspection and we'll assess exactly what's possible on your specific block — including the most cost-effective installation approach.

Above-Ground Pool Questions — Answered
Is my block suitable for an above-ground fibreglass pool?
Most sites are suitable for a Compass Maxi Rib installation — including sloped blocks, split-level yards, small courtyards and even urban sites where excavation is limited. The best way to find out is a free site inspection — we'll assess your specific block and tell you exactly what's possible.
How high above ground can a Compass pool be installed?
With the drop-edge beam system, a Compass Maxi Rib pool can be installed with over 1 metre above ground on the high side. This enables dramatic above-ground installations and pool-deck integrations that are impossible with standard fibreglass pools. Every site is assessed individually as the exact height depends on pool shape, site conditions and structural requirements.
Can an above-ground fibreglass pool have an infinity edge?
Yes — infinity and vanishing edge installations are made possible by Maxi Rib technology. The raised wall on one side creates the overflow effect, with a holding tank below. This is one of the most popular applications of the Maxi Rib system for hillside and view properties.
Does an above-ground pool cost more than inground?
The cost varies depending on how much of the pool is above ground and what site preparation and retaining structures are required. In some cases, a partial above-ground installation on a sloped block can actually be more cost-effective than extensive excavation. A site inspection will give you accurate pricing for your specific situation.
