VOID FORMERS

VOID FORMERS

STOP USING EXPENSIVE HIGH DENSITY FOAM FILLING OR HEAVY COMPACTED SOIL FILLING TO CREATE RAISED CONCRETE FLOORS AND START USING ABS DISPOSABLE FORMWORKS ALSO CALLED LIGHTWEIGHT FILLINGS VOID FORMERS.

ABOUT ABS DISPOSABLE FORMWORKS

ABS Disposable Formworks are concrete shaping structures made of recycle plastic that are used only once. They are also called void formers, permanent Formworks or single-use Formworks. They create reinforced concrete raised floors up to 300 cm, thus providing a light, fast, easy and economical filling in any structure. Reinforced concrete raised floors are constructed faster and easier, are lighter weight and are more economical than conventional filling applications.

PLATIPLUS Tree Anchoring Systems

By securing the rootball underground, our systems allow for quick root development resulting in very low mortality rates for newly planted trees. A comprehensive range of kits and installation tools are available to provide above and below ground anchoring for standard and semi-mature tree transplants up to 65.5ft (20m) high. With continuous innovation we have developed high quality standard tree anchoring solutions for on-grade and on-structure, large palm trees or typhoon locations and permanent tree anchoring situations.

Secure the rootball underground no visible tree stakes or guy wires

Prevent strong winds and gusts from pulling down your trees

PAS68 Rated Security Bollards

PAS68 Rated Security Bollards is the latest Publicly Available Specification for vehicle security barriers. It has become the national standard and the security industry’s benchmark for Hostile Vehicle Mitigation equipment, and is the specification against which perimeter security equipment is tested as part of the ongoing research to prevent Vehicle Born Improvised Explosive Device attacks.

Crash tested.
Shallow mounted.
Static & Rising.
PAS68 rated
Low maintenance
Resistant to Oxidation
Durable and Strong

PAS68: specifies a classification system for the performance of vehicle security barriers, Subjected to a single horizontal impact. It also identifies impact test tolerances and vehicle performance criteria which need to be met in order for a product to conform and be granted a classification.

The PAS68 specification defines the vehicle type, test mass and impact speed together with the required measurements, vehicle and test item details that should be recorded and reported. Post impact, and if the test is successful -the VSB stopped and immobilised the test vehicle, then the penetration distance is measured.

The Internal PAS68 core for this product is designed to stop a 7.5 ton truck at 30 mph or 48 km at 90 degrees from break- ing through the security line.

The external shroud of the bollard is manufactured from 316L Stain- less Steel with a n outside diameter of 219mm as standard with a bright satin finish as standard. Is commonly used in embassies, prisons, airports, military bases, retail parks, ATM Machines, police stations and government buildings.

Disposable Formworks

ABS Disposable Formworks are concrete shaping structures made of recycled plastic that are used only once. They are also called void formers, permanent formwork’s or single-use formwork’s. They create reinforced concrete raised floors from 5cm up to 300cm, thus providing a light, fast easy and economical filling in any structure.

Treatment Train

WTBurden Surface Water Drainage Seminar 2019 consisted of an elaborate presentation of Hydro International® Products that are installed all around Doha and case studies including an overview of the science behind the design and functioning of the Downstream Defender® (Hydro Dynamic Separator), Up-Flo® (tertiary filters), Hydro brake OptimunTM (Vortex Flow Contro Unit) and Hydro Drop® (Vortex drop Shaft)

Learn More

The HYDRO-BRAKE®  Optimun vortex flow control provides customized water quantity management for stormwater, foul or combined water across a wide range of flows and for a variety of applications.  

Explore Our Projects

The DOWNSTREAM DEFENDER® is an advanced vortex separator uses to treat stormwater runoff in pretreatment or stand alone applications. Removes total suspended solids (TSS), floatable trash and petroleum products from stormwater runoff. 

Treats the entire storm with no washout or untreated bypass flows. 

Treats flows up to 700l/s per unit.

Stainless Steel Vortex Drop Shaft

Hydro Vortex Drop Shaft is a self- activating conveyance and flow control system that dissipates the energy of dropping water, enabling customers to convey water from great heights while preventing the damage and nuisance effects associated with falling water. 

Projects

Hydro Vortex Drop Shafts are applied in sewer and drainage systems to manage risks associated with erosion, hydraulic shocks, cavitation and vibration, which have the potential to damage 

the drainage infrastructure.

Odor control and chemical erosion

 Odor issues and chemical erosion is mainly caused by hydrogen sulphide production in sewer systems. Concrete is prone to chemical erosion by hydrogen sulphide in the flow, which can reduce the design life of the sewer system. Consistent mixing of air with the flow can raise dissolved oxygen levels and eliminate

these issues.

Structural Soil Cells – Stratavault, Citygreen

Structural Cells are modular units that assemble to form a skeletal matrix that supports relevant pavement loads while providing large volumes of soil within the structure for root growth.

Essentially, Stratavault treepits may be utilised wherever trees are being planted in paved areas. There are many areas where the application of this system can assist with the healthy growth of trees in cities: Carparks, Roadways, Footpaths, and Plazas.

Stratavault has been designed to achieve major reductions in installation costs. Units snap together quickly and easily, with labour times being drastically reduced. Positive and secure connectors are a feature of the Stratavault patented design both vertically and laterally. Stratavault components are simple and fast to click together, producing an integrated matrix.

HOW DOES THIS STRUCTURE CARRY SO MUCHLOAD WITH SO LITTLE CONCRETE?

One of the most common questions we get from construction sites is “can this, carry this load?”. Yes, it can! With a more technical language, how can this structure carry these loads with so little reinforced concrete and with so little slab thickness?

Actually, the answer is simple and it is hidden in the shape we give to the concrete. The only function of ABS Plus Disposable Formworks is to shape concrete, but while doing so we are inspired by a 1,500-year-old building technique.

 

One of the most common questions we get from construction sites is “can this, carry this load?”. Yes, it can! With a more technical language, how can this structure carry these loads with so little reinforced concrete and with so little slab thickness?
Actually, the answer is simple and it is hidden in the shape we give to the concrete. The only function of ABS Plus Disposable Formworks is to shape concrete, but while doing so we are inspired by a 1,500-year-old building technique.

 

While the structural design is being made, the slab thickness of the system is calculated according to the top of the dome to stay on the safe side, but the effective slab thickness increases as you move away from the center of the dome. There is also an expansion between the column and the arch, which acts as a column cap increasing the punching area of the column.

 

 

To summarize, the reasons why ABS Plus Disposable Formwork System can carry such heavy loads with very little slab thickness are:

  • The structure rests on countless columns,

  • Having column heads on the columns,

  • Connecting each column to other columns with arches,

  • And, domes resting on arches.

The reasons for preferring ABS Plus Disposable Formwork System are:

  1. ABS’ strong references

  2. Being the lightest structural filling solution

  3. Unmatched logistics savings

  4. Very high load-carrying capacity

  5. Shortened total construction time

  6. Creating a void space under the slab (95%)

  7. Quick and easy installation

  8. Providing an uninterrupted concrete surface

  9. Environmental benefits

  10. And, it’s extremely low cost


Reference Project: IstinyePark Izmir Shopping Mall Project


The picture above with all the heavy vehicles resting on the concrete raised floor constructed with disposable formworks was taken in İstinyePark İzmir Shopping Mall Project, where ZKZY is the main contractor. This area is the main podium area of the shopping mall and will be exposed to heavy vehicle traffic. The concrete thickness in the picture is 15 cm and the formwork height is 60 cm.
