Permanent, Stay-in-Place Curb & Base-Wall Formwork

Stay-in-place concrete curb forms are a lightweight, modular, permanent form system used to cast clean concrete kerbs and base walls beneath panel and mesh fences. Made from recycled engineering plastic, the forms stay in place after the pour — an eco-friendly, economical alternative to traditional timber and steel formwork.

Thanks to standard panel sizes, each panel can be carried and assembled by a single worker without a crane. Connected to one another in seconds with plastic locks and pins, the panels adapt modularly to different wall lengths and heights.

With its light weight and fast installation, under-fence wall formwork significantly reduces labor time and cost on site; as the product stays in place on the surface, it leaves a clean face that provides added insulation to the wall.

Thanks to its rust-free, rot-free and water-resistant plastic structure, the surface is easily cleaned after application; it can be washed and painted if desired.

The modular design lets you work with the same panels on garden and boundary walls, curbs and retaining applications as well as under-fence walls. With internal and external corner pieces, spacers (spacer connectors) and bracing accessories, the system delivers a complete formwork solution.

GooPlast under-fence wall formwork features a strong ribbed structure engineered to withstand the lateral pressure of fresh concrete, giving clean and safe results. Its self-spacing design also removes the need for separate concrete-cover spacers. With UV resistance and flame-retardant (non-combustible) properties, it keeps its form and color for many years in sun-exposed outdoor applications.

Areas of Use

Walls beneath panel fences

Artificial turf pitch and sports facility walls

Park, garden and playground walls

Swimming pool and treatment plant walls

Estate and villa perimeter walls

Factory and facility perimeter walls

Advantages

When suitable reinforcement is used, the lightweight panels are carried and assembled by hand with no crane or heavy equipment, reducing labor and equipment costs on site.

The engineering-plastic structure does not rust and resists corrosion; it protects the structure even on damp and aggressive ground and provides a long-lasting surface.

The engineering plastic is UV-stabilized; it lasts for years in sun-exposed outdoors without loss of color or form. With its flame-retardant (non-combustible) property, it is a safe choice for exterior and perimeter applications.

The plastic locking system snaps panels together in seconds; thanks to the modular design, the form is set up quickly and easily, shortening application time.

Remaining permanently on the surface, the panels create a face that gives the structure added thermal and moisture insulation.

The water-resistant plastic surface is very easy to clean after application; it can be washed and painted if desired.

Made from engineering plastic, it eliminates timber consumption and significantly lowers total formwork cost.

Application Steps

Reinforcement and Preparation

The under-fence wall reinforcement is placed according to the project and the form surfaces are checked.

Joining the Panels

Modular panels are connected with plastic locks and pins to form the wall faces.

Spacing and Bracing

Opposing panels are linked with spacers (spacer connectors); the form is leveled and braced with props where needed.

Concrete Casting

Concrete is poured in a controlled manner and placed with vibration; the strong ribbed structure resists lateral pressure.

Cleaning After Application

Once the concrete has set, the product stays permanently in the structure; it requires no stripping and the surface can be simply cleaned when needed.

Frequently Asked Questions

Yes. Under-fence wall formwork stays permanently in the structure after the concrete is cast; it is not stripped and provides added insulation on the surface.

No. Because the panels are lightweight, they can be carried and assembled by hand without a crane or heavy equipment.

With its lightweight structure, it is used on walls beneath panel and mesh fences, artificial turf pitches and sports facilities, park, garden and playground walls, estate/villa perimeter walls, and swimming pool and treatment-plant walls.

Yes. The engineering plastic is UV-stabilized and does not lose color or form in sun-exposed outdoors. It is also flame-retardant (non-combustible), making it a safe choice.

It needs no plaster, because a clean plastic surface remains; decorative finishes can be applied over this surface if desired.

No. Since the product is self-spacing, there is no need for separate concrete-cover (spacer) elements.

Stay-in-place curb forms are permanent recycled-plastic moulds that remain embedded in the concrete kerb or base wall after pouring, instead of being stripped — giving a fast, clean cast with no formwork removal.
