FAQ

Is MEPCRETE (AAC) a new product?

AAC has already been in use in most European countries for more than 80 years as well as in the Far and Middle East for the past 40 years and in Australia and South America for over 20 years. AAC has been manufactured and used in the US since the mid 90's. Structures built over 75 years ago are still standing today and continue to perform well and require little maintenance. India had started to use AAC approximately since 17 years.

Where can MEPCRETE AAC Block be used?

MEPCRETE AAC Block can been used for the following applications: Hospitals, hotels, motels and restaurants, retail and warehouses, industries, cold storage, auditorium & theatres ,office buildings, education institutes construction, medical clinics and offices, religious structures, homes, multi-family projects, specialty application such as fire walls and sound walls.

Why is MEPCRETE AAC Block a good thermal insulator?

Combining AAC's R Value with 100% wall coverage thermal mass inertia and low air infiltration results in a wall system that has proven to reduce energy in most applications.

How plumbing and electrical lines are put in MEPCRETE AAC Block walls?

Chases are routed or sawn in the AAC for the lines and then patched with Cement mortar or AAC bonding agent.

Why is a vapour barrier not required in the exterior wall assembly of MEPCRETE AAC Block wall?

The enclosed cellular structure of MEPCRETE AAC Block along with the exterior finishes provides a healthy balance between resistance to moisture penetration and vapour diffusion. This balance maintains a dry system, prevents moisture condensation and allows vapour diffusion when and if any presence of vapour occurs within the wall system.

Why is MEPCRETE AAC Block considered as a Green Building Component?

Autoclaved aerated concrete (AAC) is well known as an environmentally friendly construction material. The energy consumed in the production process is only a fraction compared to the production of other materials. The manufacturing process emits no pollutants and creates no by-products or toxic waste products. MEPCRETE AAC Block is manufactured from common and abundant natural raw materials. The finished product is twice the volume of the raw materials used, making it extremely resource-efficient and environmentally friendly.

Can Gypsum board or Sheet rock be used on AAC walls?

Yes, Gypsum board or sheet rock can be attached directly to AAC walls with construction adhesive & screws, or it can be attached to furring strips. AAC should be dried before the Sheet rock is applied.

Can AAC Blocks be used with normal concrete blocks / Bricks?

Although the mix of AAC blocks & concrete blocks or bricks is not required in most cases, there is no technical restriction to prohibit the use of both products, also there’s no technical issue raised if you decide to change to material to MEPCRETE AAC BLOCKS, even if not planned initially.

What are the main advantages of AAC blocs over other building materials?

AAC is light weight, highly fire resistant, has thermal insulation value, does not decay or rot, has good sound reduction properties & is cost effective. AAC performs well is seismic situations and high wind areas. Building with AAC can reduce the quantity of materials used & labour needed to build a building.

How durable is AAC in various climates?

Autoclaved aerated concrete is extremely durable. It does not rot or decay like wood or other organic materials. It does not rust like metal. Termites and other pests do not eat it. AAC will not burn. The millions of tiny cells in AAC cushion buildings from major force, preventing progressive collapse. AAC has withstood earthquakes in Japan, the frigid temperatures of northern Europe, the harsh salty air of the French Rivera, and the hillside fires of San Francisco.

Can AAC blocks be used for basement walls?

Yes. The walls must be designed correctly to account for axial loads when used as a basement retaining wall. Due to the extreme horizontal pressures exerted by backfilling, thicker walls with additional vertical concrete and rebar reinforcement should be used, as specified by a qualified structural engineer. All walls below grade should be waterproofed as discussed above.
