The main problem of local contractors using conventional or traditional method of construction are uneconomical use of resources and employment of large number of unskilled foreign workers.

​The government has for the past decades set up guidelines and implemented policies encouraging the use of Industrialised Building System (IBS) to improve output and efficiency of the local construction industry.

The Concrewall Building System

Concrewall Building System (IBS) Sdn. Bhd. (formally known as Trek Maya Sdn. Bhd.)  is a specialist system building contractor formed to undertake and implement the innovative Concrewall (M) Building System from Italy. 

• Acquired the patented machines from Italy and set up factory for the production of panels for local use
• Carried out and obtained tests certificates and approvals from local authorities for complying with requirements of local building by-laws and design codes and standards
• Trained local workers and operators on panel manufacturing in the factory and panels installation and system implementation on sites
• Completed various types of buildings using part of or the full Concrewall (M) Building System

The Concrewall (M) Building System is a construction system based on the structuring of modular panels. The basic panel consists of a double layer of high tensile wire mesh and an inner layer of insulating  polystyrene slab stitched together using patented machines.

The Different Types of Panel

The different types of panels when assembled on site and sprayed with concrete on both sides, can be used as partitions, structural walls, floors and roof slab.

PANEL TYPES

The Concrewall (M) panel consist of:
i- Single panel
ii-Double Panel
iii-Slab Panel
iv-Staircase & landing Slab Panels

Single Panel

• Slab of polystyrene reinforced with two steel nets stitched together by electro-fusion welds
• Single panel PSM40 to PSM80
• ​Can be use as structural wall as non structural partition wall

---

Double Panel

• Two slabs of Single Panel (PSM40) stitched together with lacing wires by electro-fusion welds.
• Double panel PDM100 to PDM200
• Can be used as load bearing walls up to 20 storey high​

---

Slab Panel

• Used for floor slabs and roofs with variable thickness according to the span
• Slab Panel PSSG2&3
• Standard panels can be used for floor span up to 7m

---

Stair and Landing Slab

• Slab of polystrene cut into staircase and landing slab shapes and reinforced with two steel nets stitched together b y electro-fusion welds
• To replace complicated and slow conventional staircases construction

​

Extension of existing terrace factory

• Erecting panels on strip footing on existing floor
• Erecting staircase and landing slab panels
• Supporting and spraying concrete to  wall
• Erecting extension 1st floor slab panels 
• Concreting 1st floor extension slab
• Finished structure (extension and additional floor)

 Main Technical Benefits

Lightweight

The panel is about 2/3 the weight of an equivalent half brick wall with plaster both sides.

​

Speed in Construction

Saving of up to 20% of construction time compared with conventional method of construction.

Comparison of Thermal Properties 

• ​Half Brick Wall -1.7
• Double Glass Glazing -3.0
• Single Glass Glazing -5.0
• 100mm thick Concrewall -0.9
• 200mm thick Concrewall -0.42

Fire Rating

Single Panel Concrewall of 150mm finished thickness has achieved a fire resistant rating of minimum 2 hours (refer to test certificates)

Acoustic Properties

• Half Brick Wall -2times
• 200mm thick Concrewall - 6times

Radiation Resistance Properties

Thickness of materials required in order to contain radiation intensity of SMREM per hour:

• Lead -38mm
• Concrete & Barium -200mm
• Concrewall -160mm
• Concrete -280mm
• Full brick wall -350mm

Properties of Polystrene

• Non toxic
• Not habitable to fungi, mold, bacteria & termites 
• Non-degradation over time
• Low absorption
• High compression resistance
• Non combustible
• Chlorofluorocarbon (CFC) free
• No known health rick

Wire Mesh in Concrewall Panels

• High strength -650 to 900N/mm2
• Low Carbon -facilities electro-fusion weld
• Galvanised -prevent corrosion
