ZENBES CMU (CONCRETE MASONRY UNIT) is a Precision Engineering Block made by the ISO certified Zenbes S/B using machineries and production processes pioneered in U.S.A.
Since 1999, Zenbes CMU has been used in many commercial, residential and civil projects in Singapore for the following reasons.



High Strength     Remarkable compressive strength, low breakage and wastage and suitable for both load-bearing and non lead-bearing construction.
Flexible & Modular Construction    Zenbes CMU’s has a footprint about 05 times that of conventional building materials like clay and cement bricks resulting in shorter construction time. Though smaller than panels, Zenbes CMU can be man-handled and does not require hoisting equipment to install. Wastage arising from trimming is minimal. Zenbes CMU can be laid with cement sand mortar or the more expensive thin-joint mortar. The cost and labour of plastering are eliminated owing to its excellent dimensional consistency. Additional treatments with skim coat, paint or sealer may be chosen depending on need. Its hollow core design reduces the load on slabs and the need for excessive and expensive structural design and reinforcements.
Fire Resistance    Zenbes CMU is non-combustible and provides exceptional fire resistance (ranging from one to four hours) required by all modern construction.
Sound Insulation    Structures constructed from Zenbes CMU perform better in the area of noise insulation and noise reduction resulting in a quieter and more desirable living environment.
Lower Energy Cost    The thermal properties of Zenbes CMU ensure that buildings constructed from it are cooler in warm climate and warmer in cold climate, thereby. This reduces the energy cost needed to regulate temperature through air-conditioning or heaters.
Flexible & Adaptable    Zenbes CMU can be integrated with steel reinforcement for added flexural and tensile strength. Cleaner designs can be achieved through the embedment of rebars and the concealment of cabling and piping.

Rockface CMU Blocks are commonly used for the construction of retaining wall, sound barrier, planter box, feature & fencing wall.



Louvre CMU block was originally design to be used as letter slots at gate posts. Its unique design and properties have resulted in its used as features for both indoor and outdoor structures. It can be used in pairs and combined with fairface and rockface CMU to yield many possibilities and design options.

Acoustic properties (sound transmission class and noise reduction coefficient) are fundamental requirements in designing noise barrier. The design of noise barrier wall varies from place to place depending on the bandwidth of noise pollution. Noise barrier wall can be constructed using one or a combination of Absorptive, Diffusive & Fairface CMU Blocks.
Acoustic (Absorptive) 140mm thick
Absorptive Acoustic CMU is specially designed with a Helmholtz Resonator to provide maximum absorption of noise from a narrow frequency bands.
Rockface (Diffusive) 140mm / 190mm thick
Diffusive CMU has a random surface terrain that is particularly efficient in reducing noise from broad frequency bands (e.g. vehicular traffic noise).
