Polytunnel configurator

Tunnel type

Single tunnels stand separately on ground anchors. Multibay tunnels are bays joined side by side on shared legs, with gutters.

Which type is right for you?

Should several tunnels be joined into one block?Do you want to collect rainwater in gutters?Are you planning a very early crop?

Select answers and we will suggest a tunnel type.

Which tunnel type?

Single tunnels (Solo)Free-standing, each hoop on its own ground anchors. Easy to relocate; warmer inside — better for a very early crop.Multibay tunnels (Multibay)Bays on shared Y-legs, gutters between the bays. Lower cost per m², modular extension with further bays.

Field and dimensions

Give the field dimensions — we will calculate how many tunnels or bays will fit and what area will be under cover.

Field length

We set the tunnels along the longer side.

Field width

Gap between tunnels

A driveway or path between neighbouring tunnels.

The field has an irregular shapeWe will make staggered tunnels (stepped): bays of different lengths, matched to the field boundary.

Structure

Arch shape and steel. A round or gothic arch — we will match the hoop length to the width.

Arch shape

You choose the shape. We will match the hoop-tube length to the width.

RoundEven force distribution along the whole arch.GothicA pointed peak — sheds rain better and slides snow off.

Y-leg

A leg with a welded Y-connector, screwed into the soil, steel E370+Z275. The Ø40 mm leg fits Ø40 mm hoops only.

Leg length

0.75Ø1 m of the leg is screwed into the soil; the rest sets the side-wall height of the tunnel.

Ground anchors

Ground anchors screwed into the soil, steel E370+Z275.

StandardThey protrude only a little from the soil — the hoop tube slides onto the anchor.With an upliftThe tunnel stands 0.25Ø1 m higher. For crops that need more space under the roof.

Tunnel uplift

The anchor protrudes this much higher and the whole tunnel is raised by the same amount.

Spacing between legs (hoops)

A smaller spacing means more hoops on the same length and a stronger structure. Standard: 2.5 m.

Reinforcements

We fit reinforcements on every hoop. Some are standard; you choose the rest for wind and snow.

W standardzie

Ridge tube. The tube runs the full length of the tunnel, 20 or 40 cm below the peak of the hoops. It stiffens the tunnel from above and stops the arches from spreading.

W standardzie

Lattice cables. 3 mm steel cables run from the Y-leg to the hoop and form a spider-web net inside the tunnel. They hold the tunnel in the wind and partly relieve it under snow.

Ridge tubeoften chosenRura biegnie przez całą długość tunelu, 20 lub 40 cm poniżej szczytu wręg. Usztywnia tunel od góry i nie pozwala łukom się rozpierać.

Przekrój trzech naw tunelu ze stężeniem poziomym w wersji V zaznaczonym na czerwono: pozioma rura w górnej części łuku i dwa krótkie skośne stężenia do wręgi.

Horizontal bracingPozioma rura łączy obie strony łuku. Razem z wręgą tworzy kratownicę. Najmocniej wzmacnia tunel na śnieg.

Bracing variant

T and V are similarly effective.

T — vertical tubeV — two diagonal bracesSales advisor will choose

Strongest combination in multibay tunnels: Lattice cables + horizontal bracing. Best in a T or V variant — both are similarly effective. The cables hold the tunnel in the wind, and the bracing together with the hoop forms a truss that carries the snow.

Film

We offer only tunnels with a single film. Warranty on the film: 3 years.

Film type

Ventilation

How you want to open the tunnel to let out heat and moisture.

Tunnel sides

Either fixed curtains or side ventilation — not both at once.

Fixed side curtainsFilm fixed permanently on the sides of the block.Side ventilationYou raise and lower the film on the sides, by hand or with a drive.

Side ventilation

Gutters

Rainwater gutters between the bays are an option — tick if you want to collect water.

Rainwater guttersOption. Gutters between the bays collect water from the roof.

Assembly
