Hexprotect® AQUA vs Hexofloat® — engineering

Hexprotect® AQUA is AWTT's pre-ballasted 220 mm workhorse — 99% surface coverage, 130+ MPH wind, 25+ year life (AWTT-published). Hexofloat® is EuroCover's 190 mm AWTT design-approved variant — same patented working principle, ~30% lighter shell, 75 MPH wind, 15-year life (EuroCover-published).

Hexprotect® AQUA and Hexofloat® are the two members of the AWTT hexagonal floating cover platform sold through EuroCover Water Systems. They share the patented working principle of the AWTT hexagonal line; they target different procurement envelopes. This page is the engineering side-by-side.

How they share the platform

Both covers are hexagonal HDPE floating tiles that deploy anchorlessly onto an operating water body. Both carry a central-dome profile that sheds rainfall toward the seams between adjacent tiles, dissipates wind energy across the tile face, and absorbs small height variations across the tessellation. Both tessellate at 99% effective surface coverage (AWTT-published for AQUA; EuroCover-published for Hexofloat® on AWTT-approved tooling). Both install via shoreline launch with no anchors, no draining, no specialist crew.

How the envelope differs

Three engineering decisions distinguish the two covers.

Tile size and shell mass

AQUA is the 220 mm tile (AWTT-published) with the heavier shell engineered for the hurricane-rated wind envelope. Hexofloat® is the 190 mm tile (EuroCover-published) with a ~30% lighter shell — the basis of the EU lead time advantage (3–6 weeks vs the AWTT 2–8 week window).

Wind certification

The AWTT-published AQUA wind rating is 130+ MPH (209+ km/h) — hurricane-rated, with peer-reviewed wind testing behind the envelope. Hexofloat® carries 75 MPH (121 km/h, EuroCover-published) — sufficient for most inland EU industrial sites but below the AWTT envelope for hurricane-exposed deployments.

Service-life envelope

AQUA is engineered for 25+ years of service (AWTT-published), with peer-reviewed lifecycle validation. Hexofloat® targets 15 years (EuroCover-published) at the lighter shell mass — a deliberate trade-off for the EU manufacturing and lead-time advantage on the AWTT-approved platform.

When Hexofloat® makes sense

Hexofloat® is the right specification when EU manufacturing origin is a binding procurement constraint, a 3–6 week EU lead time fits the project schedule better than the AQUA lead time, transport efficiency matters on a large order, or site wind exposure stays inside the 75 MPH envelope (EuroCover-published — below the AWTT-published Hexprotect® AQUA wind rating) with a 15-year amortisation window. The two covers share the patented working principle of the AWTT hexagonal line — installs are identical, on-site behaviour is comparable; the trade-off is envelope vs availability.

Frequently asked questions

Are AQUA and Hexofloat® engineered the same way? #
They share the patented working principle of the AWTT hexagonal cover platform — anchorless hexagonal tiles with self-contained ballast and a central dome that sheds rainfall and dissipates wind. The envelope differs: AQUA carries the full 25-year, 130+ MPH AWTT-published specification on a 220 mm tile (AWTT); Hexofloat® delivers a 15-year, 75 MPH envelope on a 190 mm tile (EuroCover-published), the trade-off for EU manufacturing and ~30% less plastic per tile.
Why is the AQUA wind rating so much higher? #
Three engineering reasons. The AQUA tile is larger (220 mm vs 190 mm, both source-published values), giving more ballast mass per tile. The AWTT pre-ballasted shell is heavier per unit area than the EuroCover shell. And the AQUA side-wall profile is engineered for hurricane-rated lateral hold under sustained wind. For exposed sites the AQUA envelope is the right specification; for inland EU industrial sites the Hexofloat® envelope is typically sufficient (EuroCover-published).
Is the AQUA tile more expensive per m²? #
Per-tile, yes — AQUA's heavier shell uses more material. Per m² coverage the gap is narrower because both tessellate at the AWTT-published 99% effective rate. On 10-year TCO terms the gap closes again — AQUA's longer service life (25+ years AWTT-published vs 15 years EuroCover-published) defers the re-cover event. Project-specific quotations from EuroCover.
Can they install side-by-side on the same site? #
Mechanically yes — both tessellate compatibly at the hexagonal grid (both AWTT-published / EuroCover-published 99% effective coverage). Operationally most projects standardise on one cover to simplify replacement-part inventory and warranty administration. The decision is a procurement call, not an engineering constraint.
Which one ships from the EU? #
Both can ship from the EU. AQUA is held in EU stock by EuroCover (2–8 week lead time depending on quantity, AWTT-manufactured); Hexofloat® is EuroCover-manufactured in the EU on EuroCover-owned tooling (3–6 week lead time, EuroCover-published). For projects with EU-origin or REACH-bound procurement requirements, Hexofloat® is the cover whose origin certificate matches the constraint.
